Channel:
In the case of single-channel receivers, the receiver only has one channel - channel 1.
In the case of multichannel receivers the receiver has, as the name suggests, multiple
channels. The number of channels is not the same as the number of receiver outputs.
The equation below describes the number of channels associated with a receiver, based
on the number of unique channel jumpers outputs:
No. of channels - 2No.of channel jumpers -1
Thus, a receiver with four channel jumpers actually has 15 channels. Single-channel
devices have no explicit channel jumpers; but one may assume that there is always one
implied jumper. Channels never need to be numbered or addressed directly. Instead,
channels are better tied to the functionality they are associated with. The term channel
no longer refers to the physical output, but is a convenient way to describe the collective
functionality that a transmitter activates.
As an example, consider the case
in Figure 2. A multichannel receiver
is used to control certain functions
onagate.Therstreceiveroutput
is tied to the gate trigger. The
second receiver output is used to
activate the courtesy lights. Now,
suppose the user would like one
button to trigger the gates, one
button to activate the courtesy
lights, and one button to activate
both simultaneously. To achieve
this type of control, the user would
learn a unique button to a unique
channel that supports the required
functionality.
• Button 1 is learnt to the channel
thatactivatestherstoutput
only
• Button 2 is learnt to the channel
that activates the second output
only
• Button 3 is learnt to the channel
thatactivatestherstand
second outputs simultaneously

As mentioned, channels need not be numbered explicitly; but for clarity the following
channels are available on a receiver that supports four outputs:
Simultaneous Channel Activation:
Simultaneous activation is a feature that is enabled on multichannel receivers that allows
a transmitter button to activate multiple primary channels simultaneously.
The primary channels are equivalent to the outputs referred to in the section above
(Out 1, 2, 3, and 4). Each of the primary channels that are activated simultaneously will
inherit their individual activation settings. For example, suppose a user learns a button to
activate primary channels 1, 2, and 4 (Outputs 1, 2 and 3 on the receiver). Individually
thechannelsareconguredwiththefollowingactivationsettings:
• Channel 1 has a one second pulse time
• Channel 2 has a four second pulse time
• Channel 4 is a latching channel
When the channels are activated simultaneously, the activation settings are applied as
if the channels were activated individually. In other words, channel 1 activates for one
second, channel 2 activates for four seconds, and channel 4 toggles its current output
state.
It is possible, and desirable in some cases, to disable the simultaneous channel activation
feature.Toeectthis,themultichannelreceivermustbepoweredupwithaspecial
combinationofjumperstted.

Channel Compartment:
Every channel that has unique functionality, has its own unique channel compartment.
A channel compartment is a memory space that stores all the transmitter buttons that
activate the functionality associated with the channel. Because channel compartments
are unique, certain operations can be applied to a channel compartment in isolation. For
example, a user may delete, or bulk demaster an entire channel compartment, thereby
modifying all remotes associated with a particular type of functionality. Although the
concept applies to the single-channel variants, it is practically obviated since there is only
ever one channel to modify - operating on channel one is equivalent to operating on the
entire transmitter memory space.
Channel Jumpers:
Multichannel receivers have four channel jumpers. The channel jumpers are used to
select a particular channel. Each jumper relates to a particular physical receiver output.
A channel is selected by placing links on the jumpers associated with the functionality
ofinterest.Asspeciedinthechannelnomenclaturesectionabove,theactualchannel
number is not important. The user must simply place jumpers based on the functionality
thatisofinterest.However,itisworthwhilenotingthatthechannelselectedbytting
linksonjumpers1and2,forexample,isdierenttotheoneselectedbyplacingalink
on jumper 1 alone. Hence the usefulness of using the term channel to describe collective
functionality.
ChanneljumpersbehavedierentlywhendiscussingtheSmartSwitchIIinterface.
The jumpers are used to select a 4-bit binary address that addresses a particular
SmartSwitch II device on the interface bus. Table 2 below documents the jumper settings
to address a particular SmartSwitch II device. A SmartSwitch II device address is nothing
more than a receiver channel output.
Table 2 illustrates that a transmitter button that is learnt to a particular channel will
simultaneously activate the onboard relays and the SmartSwitch II device with the device
address indicated (unless simultaneous primary channel activation is disabled).
Sticky Latches:
This is a special feature on all receiver variants that allows the receiver to restore its
output state on power loss. When power is restored, the output will assume the state
itlastreectedpriortothereceiverlosingpower.Normallyareceiverthathaslatched
channels will always power-up with the channels unlatched; regardless of the output
state of the channel prior to power loss. The sticky latch feature addresses this problem
(in applications where it is seen as a problem), and restores the output state of the latch
to its state prior to power-loss.
Beep-on-Activation:
This is a special feature on multichannel receiver variants that emits a short beep from
the buzzer on the receiver, when a button that is learnt into the receiver is pressed. It
is useful in cases where the user is within audible range of the receiver and would like
an acknowledgment that the transmitter transaction has been successfully received and
decoded by the receiver.
The feature can be enabled and disabled on multichannel variants.

Primary Channels:
Primary channel is a term that is used to refer to the channels that drive a single output
(typically a relay) on the receiver board. The table below lists the primary channels for
the various receiver variants. The cells highlighted in orange indicate that the channels
are accessible through the learning interface (four channel jumpers, hence 15 channels),
but none of the channels are primary channels. The single-channel variants have one
primary channel, channel 1, and cannot access any of the other channels.

3.1. Learning the First Master
1. Tolearnthersttransmitterbuttonintothereceiver,thereceiver‘TxMemory’must
be blank. As an extension of this requirement, the channel compartment related to
the function being learnt must be blank. Although generally applicable, this extension
only really has meaning when discussing multichannel receivers.
2. In the case of multichannel receivers, start by placing links on the required channel
jumpers to select the functionality of interest. This informs the receiver that a channel
other than channel 1 will be mastered.
3. Press and hold a new transmitter button. This button is said to master the channel
that has been selected for learning.
4. Whilethebuttonishelddown,thereceiver’sStatusLEDwillashquicklytoindicate
that the system is receiving a new Nova button that is not stored in any channel
compartment in memory.
5. After approximately 5 seconds the receiver will learn the transmitter button into
memory. The receiver will acknowledge the learning operation; in particular, the LED
onthereceiverwillbegintoashslowly,thebuzzerwillemitashortdoublebeep,
and the channel functionality will activate.
6. The button can be released once the learning operation is acknowledged.
7. If the button is not released following the learning operation acknowledgement, the
receiver will begin to enter learn mode for the particular channel of interest.
8. Toeectthismode,continuetoholdthebuttondown,andcounttheslowashes
oftheStatusLEDonthereceiver.After10ashes,orequivalently,10seconds,the
receiver will enter learn mode. The transition into this mode is indicated by a long
beepfromthereceiver.Inotherwords,itispossibletolearntherstmasterand
enter learn mode with one press (even if it is for an extended period of time – 15s+)
of the transmitter. For further information on learn mode, refer to the next section
dealing with learning additional remotes.

3.2. Learning Additional Transmitters
1. To learn additional transmitters into memory using a master transmitter implies that
at least one transmitter button (that must be a master) is already learnt into memory.
In other words, the channel compartment of interest must not be blank, and the user
must have access to a master button associated with that channel compartment.
2. Press and hold a master button that has functionality on the receiver that needs to be
copied.ThereceiverLEDwillashoncepersecondasperthestandardmasterash.
The master button must be held for between 10 and 20 seconds. After 10 seconds,
the receiver will provide a long beep to indicate that it has entered the learn mode
window. Releasing the master button within this 10-20 second learn mode window,
will place the receiver in learn mode. The receiver will stay in learn mode, for a
particular channel, for a period of ten seconds, failing any additional button presses.
While in learn mode the LED on the receiver will remain on.
3. Any unlearnt button that is pressed, and held down for a minimum of three seconds,
while in learn mode, will be added to the receiver.
4. TheStatusLEDwillswitchowhiletheunlearntbuttonisactivatedwithinthethree
secondlearningwindow.Thisconrmsthreethings:
a. The button transaction is being received by the receiver
b. The button is not learnt into memory. If the button is already learnt into
  memory,theLEDwillnotturno(forthecompletelearningperiod)whenthe
  buttonispressed(refertopoints6.aand6.b.belowforfurtherclarication)
 c. Thebuttonlearningprocessisnotnalised.
5. Once the three second period has elapsed, the LED will turn on again and the buzzer
willprovideadouble-beep.Thisservesasvisualandaudibleconrmationthatthe
receiver has learnt the button being pressed. (Refer to Appendix A on page 30 for a
description of the LED and buzzer feedback)
6. If the button is already learned into memory when it is pressed, the leading edge of
the transmitter transaction is acknowledged with a short beep.
 a. TheLEDwillnotswitchoforabuttonthatisalreadylearnedintomemoryasa 
master.
 b.TheLEDwillashperiodically(64mson/448mso)ifthebuttonisdemastered,
and is being held down to remaster it. Following the three second learning
window, the button will be remastered. The LED will switch on again, and the
  buzzerwillbeeponcebrieytoconrmthesuccessfulremasteringoperation.
7. Any additional remotes learned into memory are also given master privileges.
Hence, every button added to the receiver in this way automatically becomes a
master for functionality associated with the master that placed the receiver in learn
mode.
8. Any button that is pressed while the receiver is in learn mode (whether the button
is already learnt into memory or not) will extend learn mode by an additional 10
seconds from the time the button is released.
9. If no additional buttons are pressed within the 10s learning period, the receiver will
automatically exit learn mode. This exit is signalled by an extended single beep.
TheStatusLEDalsoswitchesoandresumesitsresponsibilitiesinnormalmode.
SECTION 3THE MASTER TRANSMITTER INTERFACE

page 12 www.centsys.com
3.3. Demastering Buttons
When a Nova Helix system is commissioned, all buttons learnt into the receiver are
granted master privileges for that receiver. From a security perspective, this is not
always desirable. To overcome this potential security issue, the system has the ability to
‘demaster’masterbuttons.
1. Press and hold a master button that is associated with the same functionality as the
buttons that need to be demastered. The master button must be pressed for between
20 and 30 seconds.
2. Aftertherst10seconds,thereceiverwillbeeponcetoindicatethatithasentered
the learn mode time window. The user must continue to hold down the master
button.
3. Upon exit from the learn mode window, and entry to the demaster mode window, at
20 seconds, the receiver issues a long double beep.
4. Following the long double beep, the master button must be released. At this point the
receiver transitions to demaster mode.
5. TheLEDwillashperiodicallywithtwoquickashes(64mson/256mso)andthena
longer pause (352ms). (Refer to Appendix A on page 30 for a description of the LED
and buzzer feedback) The receiver will only enter demastering mode for a particular
channel. The receiver will remain in demastering mode for a period of 10 seconds
failing any additional button presses.
6. While the receiver is in demastering mode, any mastered button that is pressed
for three or more seconds (but less than 10 seconds) and is associated with the
functionality that the receiver is currently demastering, is itself demastered. As with
learnmode,buttonsareacteduponontheirtrailingedge-referredtoas‘trailing
edgedemastering’-thismeansthebuttonisonlydemasteredwhenitisreleased.
7. The leading edge of the transmitter transaction is acknowledged with a short beep.
This beep occurs irrespective of whether the button is a master button or not.
8. The receiver will demaster a button if, and only if, the button is a master button and
is associated with the channel of the master that placed the receiver in demastering
mode. A demastering operation is acknowledged with a short triple beep.
The triple beep acknowledgement is the point at which the transmitter button is
primed for demastering. Actual demastering only takes place when the button is
released. If the button is not released, and is held pressed for a total of 10 or more
seconds, then the button enters the deletion window (refer to the section, Deleting
Buttons, for further information on this operation).
9. If no additional buttons are pressed within the 10s demastering period, the receiver
will automatically exit demaster mode. This exit is signalled by an extended single
beep.TheStatusLEDalsostopsashingandresumesitsresponsibilitiesinnormal
mode.
THE MASTER TRANSMITTER INTERFACESECTION 3

page 13www.centsys.com
3.4. Deleting Buttons
A mechanism exists to delete an individual button that is already learnt into memory.
The transmitter must be available to delete the button in question from the receiver.
In other words, the transmitter may not be lost or stolen to remove a button from the
receiver.
1. Follow the steps to enter demastering mode. For reference follow steps one through
four in the Demastering Buttons section. The demastering mode channel need not be
the same as the channel associated with the button that must be deleted.
2. While in demastering mode, press and hold the button that must be deleted for
between 10 and 20 seconds.
3. On the leading edge of the button press, the receiver will emit a short single beep.
This is an indication that the receiver is receiving the button transmission.
4. After holding down the button for three seconds, the receiver will do one of two
things:
a. Emit a short triple beep if the button being deleted is a master button. This
triple beep indicates that the receiver is primed to demaster the button. If the
button is released in this window, it will simply be demastered (refer to the
previous section, Demastering Buttons, for further information on this operation).
b. Do nothing because the button being deleted is not a mastered button, and is
simply a button learnt into memory.
5. After holding down the button for 10 seconds, the receiver will emit a short beep to
indicate that the receiver is primed to delete the button.
6. After the short beep, the button must be released. As with all the other modes, the
required action (deletion in this case) only takes place on the trailing edge of the
transmitter transaction.
7. The receiver indicates a successful deletion operation with four short beeps.
Furthermore,theLEDashesquickly(64mson/64mso)foraperiodof700ms.
8. Once deleted, the system transitions back to demastering mode. Further buttons may
be deleted by following steps 2 through 7. Remember, the system must remain in
demastering mode to delete buttons.
9. If no additional buttons are pressed within the 10s demastering period, the receiver
will automatically exit demaster mode. This exit is signalled by an extended single
beep.TheStatusLEDalsostopsashingandresumesitsresponsibilitiesinnormal
mode.
SECTION 3THE MASTER TRANSMITTER INTERFACE

page 14 www.centsys.com
Table 4 details how to enter a particular jumper-based mode of operation by linking a
function jumper (J1 or J2) with power on the board, or before powering up the board.
The table below represents the functionality for multichannel receivers. Generally, a
channel must be set via the channel jumpers to carry out a particular operation with
respect to said channel. There are a few exceptions to this, where not placing links on
the channel jumpers invokes special operations.
• If any channel jumpers are linked, then the settings and modes of operation will
pertain to that channel
• If no jumpers are linked, then the system defaults to channel 1
In the case of single-channel receivers, the table below reduces in complexity by
removingallthe“NoChannelSpecied”cases.Eventhoughthereisnoexplicitchannel
jumper, one may assume that the channel 1 jumper exists, and is always bridged.

2. WhenjumperJ1istted,theLEDwillturnonaspermasterlearnmode.
3. Press a new button to learn it into the system. As with master learn mode, the
systemlearnsanewbuttononthetrailingedge(i.e.‘

transmitter transaction.
4. The leading edge of the transmitter transaction is acknowledged with a short beep.
This beep occurs irrespective of whether the button is already learned into memory or
not.

doublebeep,conrmingthatthebuttonhasbeensuccessfullyaddedtothereceiver’s
memory. (Refer to Appendix A on page 30 for a description of the LED and buzzer
feedback)
6. Ifthebuttonisademasteredbutton,theLEDwillashwhilethebuttonishelddown.
The trailing edge of the transmitter transaction is acknowledged with a short single
beep,conrmingthatthebuttonhasbeensuccessfullyremastered.
a. If any channel jumpers are bridged, then buttons that are demastered can only
be remastered if their associated channel matches the channel selected by the
channel jumpers.
b. If no channel jumpers are bridged, then the system will remaster any demastered
  buttons;regardlessofthebutton’sassociatedchannel.
7. Any additional remotes learned into memory are also given master privileges.
Hence, every button added to the receiver in this way automatically becomes a
masterforfunctionalityassociatedwiththechannelspeciedbythechanneljumpers.
8. Obviously, there is no timeout associated with link learning mode since the link
bridging jumper, J1, forces the receiver to stay in link learn mode.
4.2. Remastering Buttons
If a button has been demastered, it can be remastered. There are two methods to
achieve this:
4.2.1. Link Learn Remastering
1. To remaster a remote, start by entering link learn mode. For reference, follow steps 1
and 2 in the Link Learning section
2. Toremasterbuttonsassociatedwithaspecicchannel,tthechanneljumperlinks
forthatchannel.Withlinkstted,onlybuttonsassociatedwithselectedchannels
can be remastered. All other buttons will register on the receiver, but will not be
processed (as per point 6.a in the Link Learning section).
3. To remaster buttons without regard for the channel they are associated with, do
nottanylinksonthechanneljumpers.Thiswillinformthereceiverthatitmust
remaster any demastered buttons that are pressed while in this mode (as per point
6.b in the Link Learning section).
4. Withthelearnlinktted,pressandreleaseademasteredbuttontoremasterit.If
a new button (button not learned into the system) is pressed in link learn mode, it
will be learned into the system (refer to the previous section, Link Learning for more
information).
5. The leading edge of the demastered button transaction is acknowledged with a short
beep. This beep occurs irrespective of whether the button is mastered or demastered
(in fact, it will occur irrespective of whether the button is in memory or not).
6. Whilethedemasteredbuttonishelddown,theLEDwillash(64mson/448mso)
to register that the button transmission is being received, and that the button is a
demastered button. (Refer to Appendix A on page 30 for a description of the LED and
buzzer feedback).

7. When the demastered button is released, the receiver will complete the remastering
operation and remaster the button. A single short beep will signal the end of the
operation,conrmingtotheuserthatthebuttonhasbeenremastered.TheLEDwill
turn on again at the end of the operation.
8. When jumper J1 is removed, the receiver will exit link learn mode.
4.2.2. Master Learn Remastering
1. To remaster a remote in this mode, start by entering master learn mode. Refer to
steps 1 and 2 in the Learning Additional Transmitters section on page 11.
2. Only buttons that are associated with the channel of the master button that entered
master learn mode can be remastered in this mode.
3. Press and hold a demastered button (associated with the relevant channel - see point
2 above), for a minimum of three seconds to remaster it. If a new button (button
not learned into the system) is pressed in master learn mode for more than three
seconds, it will be learned into the system (refer to the section, Learning Additional
Transmitters on page 11 for more information).
4. The leading edge of the demastered button transaction is acknowledged with a short
beep. This beep occurs irrespective of whether the button is mastered or demastered.
5. While the demastered button is held down within the demastering window (minimum
3s),theLEDwillash(64mson/448mso)toregisterthatthebuttontransmissionis
being received, and that the button is a demastered button. (Refer to Appendix A on
page 30 for a description of the LED and buzzer feedback)
6. Once the demastering period has elapsed (minimum three seconds), the LED will turn
on and the buzzer will provide a single short beep. This serves as visual and audible
conrmationthatthereceiverhaslearntthebuttonbeingpressed.TheLEDwillturn
on again at the end of the operation.
7. Once remastered, the system transitions back to master learn mode. Further buttons
may be remastered by following steps 3 through 6.
8. If no additional buttons are pressed within the 10s master learn mode period, the
receiver will automatically exit learn mode. This exit is signalled by an extended
singlebeep.TheStatusLEDwillturnoandresumeitsresponsibilitiesinnormal
mode.
4.3. Bulk Demastering
Since all remotes that are added to a receiver are always added with master privileges,
a mechanism has been exposed on the Nova Helix receivers that allows certain groups of
remotes, currently learnt on the receiver, to be demastered simultaneously.
To bulk demaster remotes, follow the procedure highlighted below:
1. Ensure that there is no power on the receiver.
2. If the receiver is a multichannel receiver, place links on the channel jumpers to select
the channel that will be bulk demastered. All the buttons associated with this channel
will be demastered. If all buttons (i.e. buttons associated with any channel) must be
demastered, leave the channel jumpers unlinked. Single-channel receivers always
bulk demaster all buttons because there is only one channel compartment.
THE JUMPER INTERFACESECTION 4

page 17www.centsys.com
3. Fit the link across J1 and power up the receiver. If the channel compartment
pertaining to the selected channel is not blank (has at least one button, whether it
is mastered or not, associated with the channel), then the receiver will enter bulk
demaster mode. If the entire memory is selected for demastering, then at least one
button must be learnt into memory (on any channel) to enter bulk demaster mode.
4. AfterthermwareversionnumberhasashedontheStatusLED,theLEDwillbegin
toashquicklytosignalthatthereceiverhasenteredbulkdemastermode.Ifthe
LEDdoesnotashquickly,thenthesystemisnotinbulkdemastermode,either
because jumper J1 was not linked correctly before power-up, or because there are no
buttons learnt into memory (or associated with the channel selected by the channel
jumpers).
5. Toconrmthebulkdemasteringoperation,jumperJ1mustberemoved.Ifthe
receiver is powered down before the jumper is removed, the bulk demastering
operation is not executed. This is useful if the mode is entered accidently and no
buttons must actually be demastered.
In step 3 above, it is noted that the system will only enter bulk demaster mode if at least
onebuttonislearntintothesystem,andassociatedwiththechannelspeciedbythe
channel jumpers. If there is no button in the relevant channel compartment, then the
receiver transitions into Autolearn mode for the selected channel. Refer to the Autolearn
section for more information.
4.4. Autolearn Mode
Multichannel receivers support the ability to map buttons to channels during the
Autolearn process. Part of the Autolearn setup procedure requires the establishment
of an association table. This table will be used for all buttons learned into memory
during the actual Autolearn procedure. Autolearn mode is also limited to a maximum
of 7 days before it times out. This prevents a user from accidentally leaving the system
inAutolearnonanindenitebasis.Therearesecurityriskslinkedwithasystemthat
is placed in Autolearn mode. The 7-day timeout will minimise these risks while still
providing the convenience of auto-learning buttons.
1. ChannelcompartmentsconguredforAutolearnmustbeblank.Inotherwords,
the entire Tx Memory needn't be blank to enter Autolearn, only the relevant
compartments. As a result, it is possible to enter Autolearn mode multiple times; so
longasthechannelsconguredfortheAutolearnsessionareblank.
2. Fit the desired channel links for the channel that is intended for auto-learning. It
is possible to omit channel links and enter Autolearn for channel 1, but only if the
channel is blank. In the case of single-channel receivers, this step can be omitted
since there are no channel jumpers. Single-channel receivers always enter Autolearn
mode for channel 1.
3. Fit the link across J1 and power up the receiver. One of two possible situations will
result:
a. The selected channel (set via the channel jumpers) is blank. In this case, the
system enters the Autolearn Commissioning procedure. The receiver remains in
  thisstatewhilethelinkonJ1remainstted.Whileinthecommissioningstate,the
LED on the receiver remains on. Entry to the commissioning state is also signalled
by a long beep from the buzzer. Continue to step four.
b. The selected channel (set via the channel jumpers) is not blank, or no channel
  hasbeenselected(nochannellinkstted).Inthiscasethesystementers
bulk demaster mode. Refer to the section with the title, Bulk Demastering, for
more information on the behaviour of the system in this mode.
SECTION 4THE JUMPER INTERFACE

4. Press a button on a transmitter to establish the button-to-functionality (channel)
relationship. The transmitter that is used to establish the relationship is not learned
into memory at this initial stage (although a button that is already learnt into memory
may be used). It is purely used to establish the relationship between a button and the
selectedchannel.TheLEDwillturnowhileabuttonispressed.TheLEDwillturnon
againandthebuzzerwillsoundbrieywhenthebuttonisreleased.Thisconrmsthat
the button has been successfully received and added to the association table.
5. The last button that is pressed for a given channel will dictate the button-to-
functionality relationship. For example, suppose button 1 is initially pressed and
associatedwithachannel,channel3forargument’ssake.Ifbutton2ispressed
subsequently, and it is the last button to be pressed during the channel 3 association
process, then button 2 will ultimately be the button associated with channel 3.
6. To add another channel to the current Autolearn operation, change the channel links
to the new channel of interest. Remember, only channels that are blank can be placed
in Autolearn mode. If a channel that is not blank is selected via the channel jumpers,
theLEDwillturnoonbuttonpress,butthereceiverwillnotgenerateabeepwhen
the button is released. This will signal that the channel is not blank and therefore that
Autolearn may not be enabled for that channel.
7. Repeat steps 4 through 6 to establish button-to-functionality relationships for all the
(blank) channels of interest. (Refer to Appendix B on page 31 for an example of the
Autolearncongurationprocedure.)
8. Oncetheassociationtablehasbeennalised,removejumperJ1.Thisconrmsthe
mappingandentersAutolearnmode.Thebuzzerwillbeepfourtimestoconrmthe
transition to Autolearn mode. While in Autolearn mode, the LED will remain on while
the system is idle. When the correct transmitter button (only buttons registered in the
associationtableareaccepted)ispressed,theLEDwillturno.Whenthebuttonis
released,theLEDwillturnonagain.Thebuzzerwillbeeptwicebrieytoindicatethat
the button has been successfully learnt. All buttons are learned as master buttons.
The receiver outputs associated with the mapped channel will also activate - they will
only activate on the trailing edge of the learning transaction.
9. Once learnt, the LED will stay on while a valid transmitter button is pressed and the
buzzer will not beep on the leading or trailing edge of the transaction. The relevant
receiver outputs will activate on the leading edge of the transmitter transaction.
10. Autolearn mode will exit automatically after seven days (so long as power is not lost
to the receiver). To exit Autolearn mode early, a master button must be pressed and
held for between 10 and 20 seconds. Any valid master button will exit Autolearn - it
need not be a button that is currently part of the Autolearn process.
4.5. Link Erase Mode
There are two primary types of erase that pertain to all the receiver variants:
• Transmitter Memory Erase
• Settings Memory Erase
The procedure to perform the erase operation is documented below:
1. Start with the receiver powered up
2. If a particular channel compartment must be erased (in other words, if all the remote
buttonsassociatedwithaparticularchannelmustbeerased),thentthechannel
jumpers that select the desired channel.
THE JUMPER INTERFACESECTION 4

page 19www.centsys.com
3. If the entire memory must be erased (or the Settings Memory must be erased), then
donottlinkstoanyofthechanneljumpers.
4. Fit a link to jumper J2.
5. TheLEDwillash10timestoindicatethatitisabouttoentertheeraseprocedure.
The link may be removed at this early stage without the erase operation completing.
6. AftertheLEDhasashed10times,itwillturnon.Thisindicatesthatthereceiveris
now primed for the erase operation to take place. The procedure may still be aborted
at this late stage by removing power to the receiver.
7. Remove the link across jumper J2 to complete the erase operation.
8. TheLEDwillswitchooncetherelevantmemorysectioniserased.Thereceiverwill
return to normal operation after the erase operation completes.
ThepropertythatdierentiatesthetwoeraseoperationsisthestateoftheTransmitter
Memory. If the memory is not blank (i.e. buttons are learnt into memory), then the
receiver will perform the Transmitter Memory Erase operation. If, on the other hand, the
Transmitter Memory is blank, then the Settings Memory Erase operation is performed.
Table 5 documents the settings that are erased in each of the erase cases.

Table 6 details the respective default settings when a Settings Memory Erase operation is
performed.
It should be clear from Table 5 that channels 13, 14, and 15 are special channels. These
channels were given special default settings so that a user can easily learn to channels
that enable particular functionality. Table 7 outlines the potential special purposes.
Table 8 details the respective default settings for the receiver's special features.
Single-channel receiver variants perform a limited subset of the operations performed
during the erase procedures. The table below is equivalent to Table 5, but outlines the
erase operations for the single-channel variants.
