Port Function (4-Wire Pinout)

Some 4-wire RJ45 connectors on Clear-Com products include a software configuration that switches audio I/O pin configuration according to the device you are connecting to. This means that when connecting to Clear-Com devices, a cross-over cable is not necessary.

Clear-Com devices can have the following RJ45 4-wire pinouts:

Clear-Com 4-Wire (To Panel on older systems)
Clear-Com 4-Wire -X(To Matrix on older systems)
Configurable, (either pinout is possible, according to the Port Function toggle switch).

To set the Port Function toggle, go to Port Options in the CCM or the device front panel menu system.
