Xantech Universal Remote IR DC4 User Manual

INSTALLATION INSTRUCTIONS  
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.

FEATURES AND SPECIFICATIONS  
IR Signal & Power Inputs:  
Plug-in screw-type terminals for four-conductor connections. Handles wire sizes from 24 to 12 gauge.  
• Opto-Coupled IR IN Input and Separate IR Gnd permits IR input to be isolated from chassis and power  
supply grounds, where needed.  
RC68 Remote Programmer Code Settings for the Arrakis DC4 Control Protocols are as follows:

Output: RS232 DB9F connector.  
Power Requirements: 12 VDC 1.5 V @ 20 mA.  
Mounting: Flanges, plus supplied screws, permit easy mounting to flat surfaces.  
Dimensions: 4-3/8" L x 1-7/8" W x 1-1/4" H (110mm x 47mm x 32mm)  
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.
