2. On the XPC Gateway, check to ensure that DIP switches 3 and 4 are set to ON.
4.3 CONFIGURING THE BCM CONTROLLER
Refer to AERCO manual GF-115-C, Section 7 and program a communication address between 1 and 4
for the standard XPC Gateway. Ensure that each BCM Controller on the network has its own distinct
address. Contact AERCO if more than 4 BCM units will be placed on the network or a different address
range is required.
1. Set the communications baud rate to 9600.
2. This completes the required connections and settings and for the BCM.
3. Reattach the BCM mounting bracket to the front of the Modulex Boiler and replace all removed
panels.
Upon power-up, the Gateway should begin to read the BCM information after its preliminary checks.
