5.11 Isolated RS232 Interface PCB
The ID2000 Series Isolated RS232 Interface PCB
(PN: 124-300) enables connection of the ID2000 Series
Fire Control Panel to an external printer, terminal or third-
party-protocol station. The Isolated RS232 Interface PCB
is located adjacent to and at the left-hand side of the Base
PCB. The PCB is secured in position using one metal spacer
and SEM screw and three nylon spacers all provided with
the Isolated RS232 Interface PCB kit (PN: 020-478).
CAUTION: This RS232 port is intended for connection to

Ensure you take appropriate anti-static precautions
before undertaking this procedure.
