IR-DC4

IR/RS232 INTERFACE MODULE

The IR-DC4 is an IR to RS232 Interface Module. Specifically, the IR-DC4 converts certain Xantech RC68
Remote Programmer IR control codes into RS232 commands that operate the Arrakis Digilink 4 Hard Disk
Audio Jukebox. This allows the unique advantages of the Arrakis Jukebox to be easily integrated into
Xantech IR-controlled whole house music systems. Refer to the Arrakis DC4 Users Manual for complete
configuration and operational details.

IR-DC4

RC68 PROGRAMMER

The RC68 Programmer (available separately) contains the commands necessary for IR operation of the

DC4 through the IR-DC4.

• Use it to program universal learning devices such as learning remotes, the Xantech Smart Pads,
Controllers, etc.

• NOTE: The RC68 codes operate many other Xantech models as well, therefore, only the button
descriptions that apply to the operation of the DC4 (Overlay "F") are listed on the next page.

CAUTION: While the RC68 will operate as a separate remote
control, it is highly recommended it
the following reasons:

• Since it includes adjustable code settings, the user may inadvertently
alter the installer configurations.

• Also, since the user will require IR commands from other brands of
equipment to control the total system, in addition to those of the DC4,
all commands should be consolidated into one learning device, for
ease of use.

2. IR command assignments for the DC4 (32 total). Refer to the

Arrakis DC4 users manual for command definitions.

3. Code Group Numbers. These numbers, on the top surface of

each button, apply to other Xantech products. Ignore for this

RC68 Code Switches - Settings

Fig. 2 RC68 with "F" Overlay

Three different IR code settings are needed to operate the 3 player
zones of the DC4. To set the RC68 for the desired IR code, proceed as follows:

1. Rotate the upper switch, on the rear of the RC68 to D. Refer to Fig. 3.

2. Rotate the lower switch to 1, 2, or 3, as needed. See below:

INSTALLATION

Fig. 4 illustrates a basic IR control system in which the IR-DC4 permits direct IR control of the Digilink 4.
Make connections as shown, keeping the following in mind:

1. Be sure to add a small jumper between the IR GND and PWR GND on the IR-DC4 as shown. This

provides a ground return for the IR signal coming from the CB12 Connecting Block.

2. Plug the 781RG Power Supply and the power plug of the DC4 into AC wall outlets only after all other

connections have been made.

3. Use the RC68 to teach a learning remote the commands for each of the DC4 players.

Fig. 5 is a typical multi-room version of a direct IR control system for the Digilink 4. In this case, Xantech
Smart Pad

keypads are used as well as IR receivers. The system is configured as follows:

2

1. The DC4 is the audio music source in the system using an A/V receiver, along with other A/V sources.

2. A 789-44 four-output Connecting Block is used so that other system components can be IR controlled

in addition to the DC4. If even more components need to be controlled, a ten-output amplified
connecting block, model 791-44, could be used.

2



IR-DC4

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

s and the 780-80 IR

2

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 receiv­ers) the commands for each of the DC4 players.

7. An RC68 and the Xantech Dragon DropIR™

software are used to program

the Smart Pad
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 follow­ing should be considered when working with this con­figuration:
