Connection overview. Check the requirements below for the exact ports, cable type and supported operating mode.
No lag, no compression
Uncompressed transmission keeps mouse and video perfectly in step — suitable for editing, control rooms and gaming PCs kept out of the room.
Cinema-grade audio
Audio de-embedding supports PCM 7.1, Dolby Atmos and DTS:X for AV racks and home cinemas.
Power it from either end
Bi-directional PoC means the single adapter can sit at the TX or RX, whichever is more convenient. RS-232 and IR are passed through.
Make sure it fits your setup.
