GAP 1605
Mode of Opera ion
The GAP 1605 is a portable
programming unit used for
reading or programming
channel code(s) in the series
of Dupline
®
products.
The external switch turns
the power on/off.
When the battery is installed
and the power is on, the
GAP 1605 is ready for use.
Connect the cable between
the programming unit and a
Dupline
®
module type G..
5 keys provide the means of
operating the GAP 1605:
two keys are used for read-
ing and programming, two
keys for changing Groups
and Channels and one key
for selecting the desired
Input/Output.
The current coding is dis-
played by 4 x LEDs. The
top row of LEDs displays the
selected input or output.
The two middle rows display
the current channel group,
while the bottom row dis-
plays the current channel
code.
« In/Out - Key
This key is used to scroll
through the I/O's of a mod-
ule. If a new module is con-
nected or if consecutive
channel codes are allocated
to the I/O's, pressing the
«In/Out » key has no effect
since all Dupline
®
modules
are preprogrammed to their
physical number of inputs/
outputs. This key is also
used to switch between
consecutive and individual
coding of the I/O's. To
change the mode, keep
« In/Out pressed for more
than 2 seconds.
« Group - Key
Used to select the Group
address within the range A
to P. The Group LED will
shift one position right for
each key activation.
« Channel - Key
Used to select the chan-
nel(s) within the group. The
Channel LED will shift right
one, two or four positions,
depending on the number of
inputs/outputs. If consecu-
tive channels are selected,
then pressing the « Channel
key will have no effect.
« Read / On - Key
Used to turn on the GAP
1605 and to read the chan-
nel codes of the connected
module. When the reading is
completed, the display will
show the channel code of
the module: either 1, 2, 4 or
inputs/outputs.
2, 4 or In/Out LED's being
ON indicates that consecu-
tive channel codes are allo-
cated to the I/O's, e.g. input
1 coded to P1, input 2 to P2
... input to P .
If only one In/Out LED is
ON, then the I/O's are cod-
ed individually, e.g. input 1
to C5, input 2 to D4 etc. The
code for each I/O is indicat-
ed by a group LED and a
channel LED.
If the GAP 1605 is not con-
nected to a Dupline
®
system,
it will turn off within two se-
conds.
« Prog - Key
When the displayed I/O-
coding corresponds to the
desired channel configura-
tion, the codes will be
downloaded to the Dupline
®
module when pressing the
« Prog key.
After programming is exe-
cuted, a verification takes
place. If this verification
fails, all activated LEDs in
the display will flash two
times, and the programming
unit will switch off.
If such behaviour occurs re-
peatedly on the same mod-
ule, the module may be
faulty. If several modules fail
to download, the GAP 1605
may be faulty.
Individual In/Out channel
programming
The GAP 1605 features an
additional mode of single-
channel editing. Pressing
« In/Out for more than 2
seconds will change the
operating mode to single-
point programming. The
« In/Out key is now used
to select one of the eight
possible inputs/output, thus
making individual channel
coding possible. The In/Out-
LEDs assign the display
channel code to the corre-
sponding physical input/out-
put of the module.
In singlemode the « Chan-
nel key also has the ability
to disable an In/Out-position.
« Channel must simply be
pressed past channel ,
whereby both the Channel
LED and the Group LED will
turn off. To reenable, just
press « Channel again.
It is possible to change all
eight Inputs/Outputs, even
though some Dupline mod-
ules are built for only 1, 2 or
4 Inputs/Outputs.
To exit single channel pro-
gramming, just keep the
« In/Out key pressed for 2
seconds.
Output status setting
On receivers it is possible to
configure the status of the
outputs during Dupline
®
fail-
ure. Normally, any output of
a receiver will go off during
Dupline failure. In some cas-
es the inverted function is
desirable (e.g. light applica-
tions - turn on light if the
Dupline
®
is down).
To change output status, the
GAP 1605 must be put into
configuration mode. This is
done as follows:
• Remove any connected
Dupline
®
system.
• Keep both « In/Out and
« Group pressed, while
pressing « Read/On .
The first In/Out LED now
turns on. Connect the Dupline®
system, and press « Read/
On . If output status is set,
then channel LED 1 will illu-
minate. Pressing « Channel
will toggle the output status
On/Off.
Press « Prog to store.
If « Read/On is pressed
when no Dupline
®
system is
connected, the LEDs will
flash to indicated a false
condition. Only a successful
reading will reset this condi-
tion.
