ZXSe Hi-485 Communication Module (pcb only)

Hi-485 communication module, pcb only. Requires an RS485 card to be fitted in the control panel.
The Hi-485 nodes are able to detect and isolate transmission line faults such as short and open circuits on the network wiring. The Hi-485 modules also act as signal repeaters/boosters, which enable “High Integrity” loops of up to 12 km (39,370 ft) to be constructed.
