[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 8 systems), a larger High-Definition distribution system can be created.

For instance, two HD44C systems can be combined to create a much larger 4 source input to 8 zone output. The two HD44C systems must have its own unique address (see ADDRESS (DIP SWITCH) section). 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).
