Expanding the System Through Networking
Expanding the system can be achieved in various ways and requires the use of boards specifically
designed for communications purposes and boards that actually expand the system.
7.1
Communications: Controller Interface Card 302 - 725
The Controller Interface Card ( CIC ) provides 1 X RS232 O/P for High Level Interfaces, Graphics etc., 1 X
half duplex RS485 O/P for external LED Mimics, High level Interfaces – EWIS- , Graphics etc and option to
allow for multiple CIC interconnection.

7.2
Communications: Network Interface Card 302 - 724
The Network Interface Card provides two communication buses, RS232 and RS422, to allow the
networking of multiple panels in different combinations, eg. from Data Gathering panels to Peer to Peer
panels. Intercommunication can be via CN18 on the Main Controller (Loop Comms) or by way of a
Controller Interface Card connector CN3 (Out). Fitted to the rear of the NIC is the CPU IO Controller
(BRD85CPU) with NIC software to control the flow of communications in and out of the NIC.
