[5] RS232 EXPANSION

The HD88C and HD88CC5 can be expanded into larger systems. By using any combination of the HD88C and HD88CC5 (up to 4 units), a larger High-Definition distribution system can be created for up to 32 Zones of Component Video and Digital Audio Distribution.

The expanded HD88C units must have their own unique address (see ADDRESS (DIP SWITCH) section). The included RS232 expansion cable allows the units to be daisy chained via the RS232 control ports. This is done by connecting the SERIAL LINK port of the master to the XANTECH COM PORT of the other unit. The XANTECH COM PORT of the master is utilized to provide control of the entire system. Note that the Master is the main controlling unit. This unit is in charge of coordinating the communications between all expanded units. It is identified as the master by the unit address assigned to it. Refer to the ADDRESS (DIP SWITCH) section for further details.
