Connection overview. Check the requirements below for the exact ports, cable type and supported operating mode.
Go further than HDBaseT
Long-reach mode stretches the link to 150m over Cat 5e/6/6A/7 — enough for campus buildings, factories and large venues.
Watch the source at the rack
The HDMI loop-out on the transmitter mirrors the picture to a local monitor, handy for technicians and control desks.
Built for integrators
Audio de-embedding up to PCM 7.1, bi-directional IR and RS-232, EDID DIP switches and one-way PoC make it easy to fit into a controlled system.
Make sure it fits your setup.
Choose the right mode
Use long-reach mode for runs over 100m; HDBaseT mode supports full features up to 100m. Set both units the same.
USB 2.0 devices
USB 2.0 and older devices are supported; keep total bandwidth modest for best results.
One transmitter, one receiver
This is a point-to-point kit. For one-to-many distribution, look at AV over IP.
