Connecting the SmartLoop/NET module
Use either 4-pole shielded twisted cable for the connections or Cat 5 STP cable for Ethernet connections. The
latter will allow you to wire the data communication ring and the emergency alarm ring.

Danger:
In order to allow the ring to operate properly, the PORT-B and ALARM-B terminals must be
connected to the successive PORT-A and ALARM-A terminals.
The control panel uses an RS485 BUS for the HorNet ring node to node communications. The RS485 BUS
communicates at speeds of up to 57600 baud over distances up to 2000 metres between two nodes. The
SmartLoop/NET ports are opto-isolated, as without isolation the connection to the data acquisition
hardware to the target carries the potential for creating ground loops which will cause excessive noise in
the signal.
