7.2 ID SWITCH
The rotary ID switch is used to select the ‘ID’ of the 2157 expansion module as the host controller is
capable of giving instructions to a number of 2157 expansion modules at the same time (consult
relevant modules instructions for further details on number of supported expansion units).
The enclosure cover must be unclipped and removed to gain access to the switch. The switch should
be operated using a small screwdriver and set to match the required ID.
NOTE : The ID must be a unique number, different from the ID of any other 2157 module
connected to the host controller.
If two or more 2157 controllers are required to ‘mimic’ each other then they should be
configured with different IDs, and both configured the same in the host controller.
