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 Pad
2
s 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
.
6. As with the previous example, an RC68 is used to
teach learning remotes (used with the IR receiv-
ers) the commands for each of the DC4 players.
7. An RC68 and the Xantech Dragon DropIR™
software are used to program
the Smart Pad
2
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:
1.
Fig. 6
shows a single 291-
80 IR Receiver as the IR control
source. Multi-room, whole house
systems with many keypads and
IR receivers may also be used,
connected to the IR-DC4, as shown
in
Fig. 5
.
2. The Arrakis Music-Link Soft-
ware permits the in-room IR re-
ceivers and keypads to remotely
operate the PC, and through it, the
