The RS485 network supports up to 127 unique addresses. These are used to identify each zone of the
HSSD system. The hardware address on each termination board must be set for correct operation of the
communications network. Each termination board contains a DIP switch allowing the network address to
be set for each Detector.
If a replacement Detector is required to operate using the default settings no further action is necessary.
If, however, the default settings are not used in a particular application, then the Detector must be
reconfigured using the LaserNET software. Configuration details are contained in the LaserNET Version
3 Software Manual.
