6 meter IP-Bus Cable (male-to-male)
Pioneer's CD-IP600 is a 19.5-foot male-to-male IP-Bus extension cable (without power and ground leads). It has a black 11-pin male connector on one end, and a blue 11-pin male connector on the other end.
The cable is used to connect the Pioneer GEX-FM903XM add-on XM tuner to a compatible Pioneer receiver. When the cable is connected, you can control the XM tuner with the receiver's front-panel controls (instead of the wired remote control that's included in the GEX-FM903XM package), bypassing the FM modulator for full frequency response.
