3.	A high current power supply, the 782-00 (1A @ 12
	VDC), provides the additional current needed for
	the keypads.
4.	A 786-00 power supply, plugged into a switched
	AC outlet on the A/V receiver, is used as a source
	of system power ON/OFF STATUS voltage (12
	VDC) for the Smart Pad2s and the 780-80 IR
	Receiver.
5.	A resistor (1k to 10k Ohm) may be added in series
	with the STATUS line, if desired, to adjust the
	brightness of the STATUS LED in the 780-80 IR
	Receiver. Refer to "REMOTE ROOM 3", Fig. 5.

7.	An RC68 and the Xantech Dragon DropIR™
	software are used to program the Smart Pad2
	keypads with the DC4 player commands and the
	A/V system commands.

Fig. 6 illustrates how the IR-DC4 is connected to provide IR control of a Digilink 4 via a PC running the Arrakis Music-Link Software (Win 95/98). The follow- ing should be considered when working with this con- figuration:
