Bi-parting Gate Systems
Chapter 5
Configuring two operators to be a Master and Slave pair is easy with the Smart DC Controller. There is no
need to order a special model or any adapters. The area of the board marked Dual Gate employs a 3-wire
RS-485 serial port for communication between master and slave operators.

EQUIREMENTS
When installing a dual-operator system, the following must be adhered to:
• An electrical conduit for interconnecting wires must span between the two operators. The master-slave
communication wires and any low voltage control wires must be installed in a conduit that is separate from
the high voltage power wires. Refer to Figure 5-2.
