2-13 Installation & Wiring
DIP Switch Configurations
DIP Switches Each keypad and controller has a DIP switch as shown in Figure 13. For convenience,
set the DIP switches correctly before mounting the units in a panel.
Keypad Settings The address and termination settings on the keypad DIP switch apply to the RS-485
network that connects it to the controller. See Figure 14 for guidelines and sample
settings.
Controller Settings The address settings on the controller DIP switch apply to a network connecting the
controller to a PLC or other system host. When the DIP switch is set to zero, the default
address programmed through the COMMUNICATIONS function takes affect. Whereas
the DIP switches can set a maximum address of “7”, the COMMUNICATIONS function
can establish much higher address numbers. These settings are not related to com-
munications with the keypads.
Two sets of termination switches are included on the controller. One set establishes the
termination value for an RS-485 network connecting the controller to a PLC or other
system host. It does not apply to an RS-232 network. The other termination switches
apply to the keypad network. See Figure 14 for guidelines and sample settings.
NOTE: Both termination switches in a pair must be in the same position.
