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.

1. IR Emitter Lens.
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
application.
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.
