Note:
Do not use a screwdriver or other
metal object to pry open the case. Only
slight hand pressure is required.
Note:
The 1ZC communicates
according to the RS-485 standard. This
allows for up to 32 devices to be on a
single twisted pair. Use of a signal
repeater will allow more devices to
be addressed.
Before wiring the 1ZC controller, the
network address of each unit must be set
using a binary DIP switch located on the
controller’s circuit board.
