2.7 RS485 Communications Link

The panel is capable of communicating 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 panel
is connected to the repeaters in a 'daisy-chain'
arrangement via the RS485 Communications terminal
block, TB6, on the PCB assembly. The panel must be
fitted with the RS485 Interface Module PCB at connector
PL3 on the PCB assembly (see Section 2.7.1, Fitting
the RS485 Interface Module PCB).
The two end stations require a termination resistor to be
fitted as illustrated below.
To connect a panel to an RS485 communications link:
