RX10 Ten-Zone Receiver Decoder
Overview
The RX10 is a POCSAG receiver decoder equipped with 10 individually switchable relays, a Common relay
and an RS232 serial port.
A full function PC programming utility allows each relay to be configured to respond to a transmitted RIC
(receiver identity code) or a range of RIC’s. This will allow the user to independently energize (Close), de-
energize (Open) or alternate (Toggle) the state of each relay by transmitting specified RIC’s or ranges of
RIC’s*.
Additionally, the user can Close or Toggle each relay for a defined time period (1-255 seconds). Sending
repeat transmissions during the set time period will reset the timer, which allows a relay to be used as an
“in service” monitor. Example: as long as the unit keeps seeing the repeat transmissions within the set
time period, the relay will remain latched. If a transmission fails to be received within the set window, the
relay will drop out at the end of the set time period.
All relays have N/O, N/C and Common connections available on screw terminal blocks located on the main
circuit board (see diagram 1). The maximum contact rating of each relay is 0.5A @ 125V AC, 1A @ 60V DC.
A Common relay will latch when any of the 10-zone relays is triggered. This can also be programmed to
activate an internal sounder.
The unit can be reset by using either the key operated switch on the front of the RX10, or by transmitting a
programmed RIC. This will de-energize all relays and return the system to its initial power up state.
An RS232 serial port provides a data logging or repeater function. This can be programmed to send
transmitted messages to the serial port when either two individual RICs are specified, or when a range of
RICs is specified. Additionally, the unit can be configured to send Scope protocol for onward transmission
(using a Scope transmitter on a different frequency).
Front panel LEDs indicate when each relay is energized and a flashing LED advises when transmitted
data is received. A cool blue power LED completes the picture.
Power input requirement is 12V DC @ 0.7A, via the blue latching connector provided.
*Each RIC must be a 7-digit number in the range 0000008-2097151, excluding ranges
2007664-2007671 and 2045056-2045063.

Section 1: Installation
Certain precautions in sighting of the unit apply. As with all radio equipment, attention must be given to
the aerial selected and where the unit is mounted in relation to the transmitter being monitored. If the
unit is to be used with a second transmitter, it should be sited as centrally as possible within the secondary
area to be covered, although it must of course be within adequate distance of the originating transmitter.
It is therefore essential that adequate signal reception is checked before fitting the unit in the desired
location. Using a Yaesu VR-120D Communications Receiver programmed to the required frequency, a
signal strength of 5 or greater is deemed to be sufficient to provide a reliable consistent link. Readings
below this level may lead to poor reception in adverse atmospheric conditions.
Ranges of up to 1 mile can be achieved quite easily except where the conditions are such that signal paths
are severely obstructed due to reflections or physical obstacles placed in the way. Such conditions may be
experienced where there are a large number of metallic structures around the site, or where the receiver is
sited in a hollow, i.e. below the level of the transmitter or its aerial.
To mount the unit on the wall, remove the two screws from the front of the case and separate the cover
from the base plate, taking care not to stress the ribbon cable which connects the front panel indicators to
the main circuit board, as well as the cables which connect the Reset switch to the main board.
For ease of installation, the ribbon cable can be removed from the main board by lifting the collar either
side of the connector (see diagram 1). This will release the locking mechanism and the cable can be
withdrawn. The Reset lead can be unplugged from CN7 on the main board.
The RX10 base plate should be fixed to an even wall surface using suitable screws fitted through the 4.75
mm holes provided in the chassis plate. Hold the chassis up to the chosen location and with the aid of a
pencil, mark the position of the mounting holes.
Place the base plate over the mounting holes and fit the fixing screws. Check that the chassis plate does
not bend and that the screws do not snag or pinch any internal cables.
Connect the antenna to the unit via the BNC connector located at the top of the housing. If the antenna is
an external type, or an antenna which is separate from the RX10 unit itself, care should be taken to ensure
that certain installation criteria are met, as detailed next.
Warning: Do not use the chassis plate as a template for drilling the holes into the wall. Hammer drills
vibrating through the chassis may irreparably damage the quartz crystals on the printed circuit boards.

Some major points to consider when installing equipment:
1. Never install antennas near or adjacent to telephone, public address or data
communication lines, or overhead power cables.
2. Avoid, wherever possible, running antenna coax alongside other cables and avoid kinks and
coils. Pre-terminated cable should not be altered.
3. Avoid mounting the receiver in the immediate vicinity of telephone exchanges or computer
equipment.
4. Always use 50 ohm coaxial cable between the antenna and the receiver. If cable runs
exceed 5 meters, always use low loss 50 ohm cable such as RG213 or UR67 to a maximum
of 15 meters.
Coaxial cable intended for TV, Satellite or CCTV installations is normally 75 OHM
and therefore totally unsuitable for any receiver installation manufactured by
Scope.
5. Also remember that the performance of the system will be affected by the type of material
the unit is mounted on and its surroundings.
The following is a list of materials that this receiver will be adversely affected by if
mounted on or if mounted in close proximity to:
a) Foil back plasterboard
b) Metal mesh or wire reinforced glass
c) Metal sheeting, large mirrors or suspended ceilings
d) Lift shafts
All of the above can reflect radio waves and thereby reduce the capability of the receiver to
perform its desired functions.
6. The circuit boards within this equipment may be harmed by Electrostatic Discharge (ESD).
Installers should ensure that both themselves and the system’s chassis are grounded before
beginning any installation and should ensure that adequate anti-static procedures are
adhered to at all times.
Fit the required switch cables to the appropriate relays. These are labeled Zone 1 to Zone 10 and Common
(the Common relay operates when any zone is triggered). Terminals are available on each relay for
Normally Open, Normally closed and Common.
Finally, connect the blue latching power connector to a 12V DC @ 0.7A power supply, observing the correct
polarity, as shown in diagram 1.
To program and configure the unit, the 9 way D connector must be connected to a COM port on a PC using
a standard 9 way serial cable (see Section 3, Programming Utility). This port can also be used to connect
the unit to a serial printer or PC for data logging purposes, or to a Scope transmitter for repeater
application.

Note! When re-fitting the front panel ribbon cable, ensure that the connector collar is
raised and check that the cable is square to the connector. Ensure that the cable runs
straight in the direction shown. Gently insert the cable tail as far as it will go, then
push down equally on both sides of the connector collar.

Section 2: System Operation
The RX10 can be used to remotely switch up to 10 different circuits. This can be achieved by independently
programming each zone with simple Close and Open latching commands. Zones can also be programmed
for momentary operation, and if required, a single command can be used to toggle the state of each zone. A
Reset function returns all zones to their initial state. This can be activated either over the air (by
transmitting the programmed command) or by operation of the front panel key switch. A Common relay
will latch when any zone is active. This can also be programmed to operate an internal sounder. The relay
can be used for connection to an external sounder or light providing a remote indication of system activity.
Both the configuration and uses of the RX10 are limited only by the user’s imagination, so here we will
provide just a few examples of how its functionality can be utilized.
Example 1: You want to use Zone 1 to switch on a light when you transmit a command. You then want to
switch the light off by transmitting a different command. To do this, connect your switch wires to the N/O
and Common terminals of Zone 1. In the RX10 Pro Configuration utility, click on the Chan 1 tab. In the
“Close” section, enable the tick box then enter the chosen RIC (or range of RICs) for switching the light on.
In the “Open” section, enable the tick box and enter your chosen RIC (or range of RICs) for switching the
light off (for a fuller explanation of programming the RX10, see Section 3).
When you transmit the “Close” RIC stored in Chan 1, the relay contacts will close, completing the circuit.
The Zone 1 LED on the main board and on the front panel will light. The Common relay will also operate
and the Common LED on the main board and front panel will also light. When you transmit the “Open”
RIC stored for Zone 1, the relay contacts will open, breaking the circuit. The Zone 1 LEDs will extinguish,
the Common relay contacts will open and the Common LEDs will extinguish.
Example 2:You want to use a single command on Zone 3 to switch a motor both On and Off for a
10-second period. To do this, connect your switch wires as in Example 1 if you require the motor to be in
the Off state when the RX10 is initially powered up or reset. If you require it to be ON in this state,
connect the wires to the N/C and Common terminals. In the RX10 Pro Configuration utility, click on the
Zone 3 tab, then set the “Tmax” value to 10 (seconds). Now enter your command RIC (or range of RICs) in
the “Toggle” section and enable the tick box. When you transmit the stored “Toggle” RIC, the motor will
run for 10 seconds, then stop. Transmit again to run the motor for a further 10 seconds. If you transmit the
RIC whilst the motor is running (i.e. during the set time period of 10 seconds), it will stop. Transmit again
to run the motor for a further 10-second period.
Example 3:You have a “supervised” system where the transmitter sends out test calls at timed intervals.
If the receiver fails to receive any test calls, you want to signal this by opening a pair of contacts. To do
this, in the RX10 Pro Configuration utility choose a zone (Chan) and set the Tmax value to a period greater
than your transmitter’s test call period. Enable the “Close” function and enter your test call RIC. Wire the
signal cables to the N/O and Common terminals of the selected Zone.

RX10 Ten-Zone Receiver Decoder
Note that the relay contacts will be open until the first test call is received when they will close for the set
time. Because the test call interval is shorter than the set time, the timer is reset with every successfully
received call, so the relay contacts remain closed until a call is missed when they will open until a call is
successfully received.
Because both N/O and N/C terminals are available for each relay, this can cause confusion when deciding
on whether to select the “Close” and “Open” functions. To avoid confusion, the “Close” function for each
relay can be best described as “when the relay is energized”, and the “Open” function as “when the relay is
de-energized.”
For example, if the N/C terminal configuration is used, when the “Close” command RIC is transmitted, the
relay will energize and the contacts will go open. After this, if the “Open” command RIC is sent, the relay
will de-energize and the contacts will close. Similarly, if the N/O terminal configuration is used, when the
“Close” command RIC is transmitted, the relay will energize and the contacts will close. After this, if the
“Open” command RIC is sent, the relay will de-energize and the contacts will open.

Section 3: Programming Utility
a) Comm Port Configuration
Install the software provided on a PC running Windows XP.
Prior to programming the RX10, enter the Comm port and the comms baud rate, which you are using on
your PC to program the RX10.
Fit a standard 9 pin “null modem” serial cable between your PC Com port and the RX10 serial port.
To check the set baud rate of the RX10, select “GET” to read the stored data. The unit is now ready to
accept programming data.

c) Options
i) Reset
A specific RIC + beep type can be used to reset the RX10 over the air. The Enable tick box must be checked.
ii) Common Relay/Sounder
When any relay zone is activated, the common relay will be triggered. This can be programmed to stay
latched by checking the “Fixed” option, or it can be programmed for momentary activation by checking the
“Timed” option and entering the duration required (maximum is 255 seconds). The sounder can be
programmed to activate when the common relay is triggered by checking the “Link Common
relay/Sounder” box.
iii) Repeated Toggle Command Filter
Where the transmitter is programmed to send repeat calls for added integrity, it may be required to filter
out these repeats if the “Toggle” function is being used (otherwise the relay will change state every time a
repeat call is received). Enter the required time in the box provided (1-255 seconds). Note that this is not
necessary where only the “Close” or “Open” functions are being used, as these will ignore repeats of the
same RIC.

12 of 12
RX10 Ten-Zone Receiver Decoder
d) Relay Configuration
Each relay can be controlled using a range of RIC’s to close, open or toggle the state of the relay.
As previously explained, “Close” means “energize the relay,” “Open” means “de-energize the relay.”
“Toggle” means change the state of the relay each time the command RIC is received.
For latched (continuous) activation, the “TMax” box must be set to “0.” For “Close” and “Open” functions,
repeat receipts of the same activation RICs will be ignored, unless a timed activation state has been set, as
detailed below.
Where a timed state is required, this can be set between 1 and 255 seconds, after which the relay will
revert to its previous state. As explained above in Example 3, if the same activation RIC is received during
the timed period, the counter will be reset, thereby extending the period by the set time.

RX10 Ten-Zone Receiver Decoder
e) Serial Data Output
Where it is required to send message data for onward transmission or for logging purposes, the serial port
can be enabled. The RX10 can be programmed to accept either two individual RICs or a range of RICs.
Note: the RX10 does not provide time/date stamping, although this function could be facilitated using
suitable software on a PC, or by using a POS style printer with an onboard real time clock.
i) Serial Data – RIC 1 and RIC 2
Where individual RICs are selected, a specific beep type (A,B,C,D) must also be entered. When the chosen
RIC + beep type + message is transmitted, the message will be passed to the serial port.
ii) Serial Output Logger
A range of RICs can be entered, together with either a specific beep type or “All,” where any beep type is
valid. If the serial port is being used to pass data to a Scope transmitter (a repeater application), the tick
box “Scope Protocol Output Format” should be checked. This will output the Scope control codes + RIC in
front of the message. Where numeric messages are sent for onward transmission, the tick box “Interpret as
numeric messages” must be checked.
