The transmitter's at the source end. This is the box that sits next to your display and pulls the signal in. One Cat cable carries 4K video, audio, RS-232, IR, and power – no extra brick on the bench.
Bi-directional RS-232 means you can talk back to the source from the display side. Touch screens, barcode scanners, serial terminals – all work through the same cable. IR goes both ways too, one port at a time.
Rack-mountable if you're building a panel. Metal housing. Plug in, power on, done
