Figure 8-11 shows a Sample Modbus Network wiring diagram for a Master EMS/BAS controlling

BCM Controller Slaves. This Figure shows an EMS or BAS Master equipped with a RS485 port.

If the EMS or BAS contains a 4-Wire RS485 port, refer to Detail “A” for wiring details. If the

controlling Master EMS/BAS contains only a RS232 port, a RS232-to-RS485 converter will be

required to interface with connector Y2 at each BCM Controller. It should be noted that this

diagram is only intended as a guide and does not include all possible scenarios. Refer to the

EMS/BAS manufacturer’s manual prior to attempting any network wiring connections.
