Crestron CNRJ11 4-Wire to RJ11 Cresnet Converter

Cresnet exists in two physical forms: the four-conductor cable landed on screw terminals, and the modular RJ11 patch cable used by touch panels and portable devices. The CNRJ11 bridges them. It presents one 4-pin 5 mm detachable terminal block and one 6-pin RJ11 female jack, wired in parallel one to one, so either end can be the source and the bus passes straight through without translation or buffering.

A green PWR LED lights when 24VDC Cresnet power is present at either port, which turns the converter into a quick continuity check when a device downstream will not come up. The housing is 3.25 in. wide and 2.00 in. deep, small enough to sit inside a rack, behind a panel or under a table where the transition needs to happen.
