Matrix: How do I link an Eclipse frame to an Matrix +3 frame?
Eclipse to Matrix+3 frame linking can only be accomplished with dumb trunk lines (CAT-5 trunking cables with only the audio pairs used). This allows for only port to port trunks with audio signals passing back and forth between the the two frames.
The RS-422 data pairs should not be linked between the two frames as the RS-422 data is not compatible between the two frames. Loop the RS-422 data pairs at each port or simply do not use at all.
See attached document below for wiring information.
