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.

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.
