2.7 RS485 Communications Link
The RS485 Interface PCB (PN: 124-247) enables the panel to
communicate with a maximum of sixteen (16) repeaters (active
IDR-2Aor passive IDR-2P) or mimic panels (IDR-M) (for further
details concerning the repeaters refer to 997-411, IDR-2A, -2P
& -6A Repeaters User Manual or 997-412, IDR Mimic
Installation and Commissioning Manual). The Isolated
RS485 PCB is located within a recess on the left-hand side of
the Main PCB. The PCB is fitted to the chassis using three
nylon snap-top spacers, provided with the Isolated RS485
Interface PCB Kit (PN: 020-479), and secured with a provided
M3 SEM screw to the metal spacer provided by the chassis.
To fit the Isolated RS485 Interface PCB follow the
instructions below.
Before starting, make sure you have a PC back-up of
the panel’s current configuration data.
Ensure you take appropriate anti-static precautions
before undertaking this procedure.
With the front cover(s) removed (see Section 2.5.1) and
ALL power disconnected, proceed as follows:
1Fit the nylon spacers (A) into the three provided holes
(B) in the chassis (C) - top right-hand position and both
bottom positions - by pushing them firmly into place until
they snap into position.
2Observing anti-static precautions, remove the RS485
Interface PCB from its packaging. If, after inspection,
no damage has occurred in transit and with it correctly
orientated, carefully offer the PCB to the three snap-
top spacers fitted in step 1. Working in a clockwise
direction, carefully push the PCB onto the snap-top
spacers (positions D) until the PCB is secure.
3Use the M3 x 8mm SEM screw (E) to secure the Isolated
RS485 PCB to the metal spacer (position F).
4Make all necessary wiring connections to the Isolated
RS485 Interface PCB - see details below.
5If the ID51/52 panel is NOT an end station, ensure the
jumper link is fitted in position JP1/2/4 (OFF) on the
Isolated RS485 PCB - this disconnects the line
terminating resistor. If the panel is an end station,
ensure the jumper link is fitted in position JP3/5/6 (ON).
With the IDR Series repeater, ensure the jumper link is
fitted as follows: an intermediate station - position JP1/
3/5 (TERM OFF); an end station - JP2/4/6 (TERM ON).
6If no other PCBs require fitting re-connect mains
power and the batteries and replace the front cover(s).
7To replace the Isolated RS485 Interface PCB, first reverse
the above procedure, steps 2 to 6, and then fit the
replacement RS485 Interface PCB using steps 2 to 6.
2.7.1 Cables and Wiring
8Make the following wiring connections to the Isolated
RS485 Interface PCB:
i Ribbon cable at socket SK2 from the Main PCB socket SK1.
ii Cable at socket SK1 from the next station on the
network (as applicable).
Make sure you
have a PC back-up
of the current
configuration data.
WARNING -
Disconnect ALL power
from the ID61/62 panel
when carrying out this
procedure.
