Assign a unique node address to each CoreSense™ diagnostics module using switches 1 through 5.
a. Set the communications baud rate for the module using switch 7. "Off" = 19200 baud, "On" = 9600 baud.
The baud rate for each module should be set to match the rack controller.
b. Set switch 8 to "Off" for no parity, to "On" for even parity.
c. Set switch 9 to "Off" for stand-alone mode, to "On" for network mode. Network mode will generate a
communications error if the rack controller fails to communicate with the device. For stand-alone mode, no
communications are expected so the communication error is blocked.
d. Factory default setting is "On" for dip-switch 10, ie, discharge temperature protection. If you want to
disconnect the discharge temperature sensor, turn off dip-switch 10.
Push the reset button after changing the switch settings.
Ensure that the dip-switch settings on each module match the settings for the selected controller communication
port.
