Thank you for the reply. I Googled the cable and found a post on Avsforum in the official Velodyne support thread (page 284 if anybody is interested). The question is if Global Cache GC-CGX converter cable is usable with signals from an Itach IP-IR.
Strangely, the answer from Velodyne support is: “The Digital Drive series subwoofer’s IR input connector is not compatible with Xantech or other brands. It is a proprietary remote eye accessory available from Velodyne.”
Further down the tread he follows up with:” The external remote eye is available from Velodyne, but is nothing more than an external IR sensor with a long cable. The idea being if your subwoofer was placed someplace that prevented the integrated IR sensor from easily detecting the remote, you could place this sensor near the rest of your gear then run the cable to the subwoofer.”
I don’t get it. Velodyne FAQ explains this IR port to be compatible with Xantech and Elan brand products. This guy however claims it’s not compatible with anything other than a proprietary IR sensor.
I think I’ll be using one of the IR emitters on the sub.
