EXT-USBC2XI-100M: Dual-Host USB 3.2 Extender Overview
Extends USB 3.2 Gen 1 (5Gbps) 100m/328ft over one CAT6a F/FTP cable, with USB-C and USB-B host inputs, RS-232, FSYNC and 24V PoC on the same link.
What the WP-EXTHDTC150 is and where it fits
The WP-EXTHDTC150 is a point-to-point HDBaseT extender kit that carries an uncompressed HDMI signal from a wall-plate transmitter to a compact box receiver over a single CAT6/6A cable. The transmitter mounts in a US 1-gang box and takes two sources — one HDMI and one USB-C — with automatic or manual switching between them. The receiver drives the display over HDMI and de-embeds analog stereo on a 3.5mm output for a local audio tie-in. It is built for jobs where the length of the run, rather than USB or KVM extension, is the constraint.
How far can it send 4K, and over what cable?
Over a single CAT6/6A run, the kit reaches up to 120m (394 ft) at 4K2K@60Hz 4:4:4, and up to 150m (492 ft) at 1080p@60Hz 4:4:4. The link passes 18Gbps of uncompressed HDMI 2.0b video and is HDCP 2.2 compliant, holding full 4:4:4 color at the 120m 4K2K@60Hz distance. Color depth of 8-bit, 10-bit and 12-bit is supported, along with RGB 4:4:4, YCbCr 4:4:4, YCbCr 4:2:2 and YCbCr 4:2:0, plus HDR, HDR10, HDR10+, Dolby Vision and HLG pass-through. Terminate the cable straight-through at both ends — wire both connectors to the same pin order and do not cross-connect.
Do I need a network switch or an AV-over-IP encoder?
No. The transmitter and receiver connect directly to each other across the one CAT6/6A cable, with no AV-over-IP encoder, decoder or LAN switch to commission between them. The HDBaseT OUT on the transmitter goes straight to the HDBT IN on the receiver. That keeps the signal chain to two boxes and one cable, which is the point of using HDBaseT here instead of a networked distribution system.
How does power work across the two units?
The kit uses bi-directional PoC (Power over Cable): connect the supplied 24V/1A adapter at either end, set the transmitter's PoC switch to ON, and that unit feeds the other over the CAT cable, so the second unit needs no local supply. If PoC is switched OFF, the far unit must have its own power. The transmitter draws 4.5W maximum and the receiver 4.7W maximum. The mains input on the adapter accepts AC 100–240V, 50/60Hz.
What control and audio does the link carry?
Bi-directional IR, RS-232 and CEC pass through the cable, so the control system can operate both source and display from either end — IR IN on one unit drives IR OUT on the other. The IR path runs at 5Vp-p over a wideband 20kHz–60kHz range. On audio, the HDMI signal carries formats up to LPCM 7.1, Dolby TrueHD and DTS-HD Master Audio, while the receiver's 3.5mm output provides de-embedded analog stereo (LPCM 2.0CH) for powered speakers or a local amplifier.
Which sources can the wall plate take?
The transmitter presents one HDMI input and one USB-C input, both supporting video up to 4K60 4:4:4. Press the SOURCE/AUTO button to switch between them; a green USB-C LED and a green HDMI LED show which channel is selected. Holding the button for 3 seconds toggles auto switching, indicated by a blue glow — useful when you want the plate to follow whichever source becomes active, or when you need to lock a specific input manually. The metal-enclosure transmitter measures 2.75" × 1.54" × 4.49" and the receiver 5.51" × 2.56" × 0.71".
