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-2A or 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:
1
Fit 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.
2
Observing 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.
3
Use the M3 x 8mm SEM screw (E) to secure the Isolated
RS485 PCB to the metal spacer (position F).
4
Make all necessary wiring connections to the Isolated
RS485 Interface PCB - see details below.
5
If 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).
6
If no other PCBs require fitting re-connect mains
power and the batteries and replace the front cover(s).
7
To 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
8
Make 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.
