[6] AC POWER INPUT
Standard IEC 3-Conductor AC Line Cord Receptacle for plug-in of a 3-conducator power line cord. Be
sure to note if the power receptacle is domestic (120VAC type) or international (240VAC type).
[7] RS232 EXPANSION
The HD44C and HD44CC5 can be expanded into a larger system. By using any combination of the
HD44C and HD44CC5 (up to 4 units), a larger High-Definition distribution system can be created.
For instance, two HD44C units can be combined to create a much larger 4 source input to 8 zone
output. The two HD44C units must have their own unique address (see ADDRESS (DIP SWITCH)
section). The top unit (master controller) must always be addressed as UNIT 1. See Section 8 for
setting the unit address. The included RS232 expansion cable allows a single RS232 control port to
be used to command the entire system. The expansion cable is connected between the DB9 (5) and
3.5mm stereo mini jack (7).
IMPORTANT NOTICE
The top unit (master controller) must always be addressed as UNIT 1.
