Section 3
— Connecting a Master / Slave Pair
Configuring two operators to be a Master and Slave pair is easy with the Smart Touch 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 RS485 serial port for
communication between Master and Slave operators.
NOTE
: Master and Slave operators must have the same version of the Smart Touch Controller and the same software
version loaded on both machines.
1. An electrical conduit for the interconnecting wires must span between the two operators. This conduit must
contain only low voltage ≤ 24V control and signal wiring.
2. Complete the installation of both of the operators as separate machines and verify that their basic functions are
correct as solo operators before interconnecting them.
3. The two gate operators should be supplied by home runs from separate 20A circuit breakers in the main panel,
but if there is only one circuit, be absolutely certain that the breaker and wire size is sufficient for the load of two
motors. See the
Appendix
pages 59 and 60.
4. External control inputs, vehicle detectors and entrapment protection sensors may be connected to either gate
operator without regard to preference.
5. To interconnect the two operators, route a shielded twisted triple cable between the electric control boxes and
connect to the RS485 Dual Gate terminals, in matching order on both machines. In the RS485 shaded area,
connect the terminals for Master Com to Slave Com as shown in the table below:
Slave

B

Shield wire to Ground*
*
NOTE
: Only ground to one operator. Do NOT attach the
shield wire to both operators. Cut off the shield and insulate
(tape up) the exposed strands at the other operator.
6. The Installer Menu in each operator must be set as a Master or a Slave under menu item [
]. Set one operator
as a Slave [
] and the other as a Master [
]. If the function of any external input is to be different than the
factory default, configure for the desired function on the operator where that input is connected. Internal functions,
such as the close timer or reversal distance, are controlled by the Master operator regardless of the settings in the
Slave.
7. Once set as a Master or a Slave, the operators are in constant communication with each other. If that
communication stops because the wires become severed or one operator is turned off, both machines will cease
functioning and the
appears on the display (a Master/Slave communication error). This error cannot be reset
until both machines are functional and communicating properly again.
