Master/Slave Systems
Two MSC-400 Controllers can be linked together for control of up to 22 Connected Devices via IR (22) or IR
U
and RS232 (the number of IR devices will vary by system, 10 RS232 devices max). Other than using IR/RS232
Port 12 for a Smart Macro Control Buss between Controllers, both Controllers are fully capable of all func-
S
tions. All Sensor Ports are available for Device Status Sensing of up to 12 devices, all Relays are available for
up to 4 switch closure connections and both Controllers can be connected to Media Center PCs. When mak-
I
ing connections in a Master/Slave system, follow all previous instructions and include the following connec-
N
tions: See section: Programming Master/Slave Systems for additional information.
