Re: Kenwood NXR 810 repeater

The 8 pin is used by the mic...but the programming pin outs remain?the same so either RJ45 8 pin or RJ14 6pin works.. And actually only 4 wires are used...TX data, RX data, GND and power for the interface IC ...using the DB25 on the back doesn't use power iirc as it's a straight RS232 connection to the PC?

I prefer to use the 8 pin modular cable.? That allows me to go to a site
and make programming changes from the front panel of the repeater and
not have to go in the back and possibly remove a db-25 that connects to
something else like a controller.? The less time I spend in the back of
the rack, the less time I have to accidentally disconnect something else.
