EXT-HD50C: HDMI over Cat5e/6 Extender Explained
The EXT-HD50C sends HDMI over one Cat5e/6 run — 70M at 1080p or 40M at 4K@30Hz on Cat6 — with HDMI 1.4/HDCP 1.4 and loop-out.
What the WP-EXTHDTC100 does
The WP-EXTHDTC100 is a US 2-gang wall-plate transmitter and a receiver box that together move video, audio, USB 2.0 and control down a single CAT6/6A run. The plate takes two inputs — one HDMI (Type A) and one USB-C carrying DisplayPort 1.2a Alt Mode — and switches between them automatically, manually, or by priority. At the far end the receiver hands off HDMI, a balanced or unbalanced stereo audio output, and USB 2.0 device ports. It is built for bring-your-own-device rooms where the camera, speakerphone and display sit away from the table and a presenter arrives with just a laptop and one USB-C cable.
How far will it run, and at what resolution?
The kit reaches up to 100m (328 ft) over a single CAT6/6A cable, carrying up to 4K60 4:4:4 8-bit over HDBaseT 2.0. Both the HDMI 2.0b and the USB-C (DisplayPort 1.2a) inputs accept up to 4K60 4:4:4 with HDCP 2.3 and 18Gbps of video bandwidth, and the resolution range runs from 640x480p60 up to 4096x2160p60. HDR, HDR10, HDR10+, Dolby Vision and HLG all pass through. The short passive HDMI or USB-C cable from the source to the plate should be no more than 3m (9.8 ft).
Does the USB-C connection charge a laptop?
Yes, up to 60W — but only when the wall plate has its own power. USB-C charging draws from the included 24V supply connected to the plate's DC IN. Because the kit uses bidirectional PoC, one 24V/5A supply can power either end and feed the other over the CAT cable; however, if you power the plate from the receiver over PoC, video and USB still work but the USB-C port will not charge. To charge laptops, put the supply at the wall plate. Maximum draw is 111.8W with 60W charging active, or 41.74W without charging.
Can the room's camera and speakerphone connect at the display?
Yes. The receiver adds four USB 2.0 device ports (two USB-C and two USB-A, each 5V/1A) for a conference camera, speakerphone, keyboard, mouse or touch display. USB 2.0 travels over HDBaseT 2.0 at up to 255Mbps and follows the selected input: the USB-C input carries its own USB, and a USB HOST port (USB-B) on the plate, bound to the HDMI input, gives an HDMI-connected room PC the same devices when HDMI is selected.
How is the room controlled?
Bidirectional IR and RS-232 pass through the link, and the kit accepts API commands over RS-232 or the USB-C SERVICE port. A DISPLAY ON/OFF button on the plate powers the display on or off via CEC, RS-232 or IR, whichever you enable, and the plate's IR window supports IR learning. EDID management and CEC pass-through are handled across the link as well.
What is in the box
The kit ships with the wall-plate transmitter, the receiver, one 24V/5A desktop power supply, IR blaster and receiver cables (1.5m each), a 5V IR blaster cable, Phoenix connectors (two 3-pin and one 5-pin 3.5mm), two mounting ears and eight machine screws. The transmitter has a white front with a silver back; the receiver is a black iron box. Operating range is 32°F to 104°F (0°C to 40°C).
