5Gbps Dual-Host USB-C Extender over CAT6a (100m/328ft) with Dual 4K HDMI Out
KanexPro EXT-USBCPD2X4K-100M, USB 3.2 Gen 1 Extender 100m, Dual USB-C Host Extender, USB over CAT6a, HDBaseT USB3 Extender, Dual HDMI Output USB Extender…
Extend two USB-C host laptops to a remote location up to 100 meters away — with dual 4K displays, USB peripherals, analog audio, and control — over a single CAT6a cable. The KanexPro EXT-USBCPD2X4K-100M is a 5Gbps USB 3.2 Gen 1 extender kit that delivers full USB-C docking station functionality at distances far beyond standard cable limits. Two selectable USB-C host ports on the transmitter support auto/manual switching for seamless presenter handoff, while USB-C PD charging up to 100W powers laptops directly from the TX. At the receiver, dual HDMI 2.0b outputs deliver mirrored or extended displays at up to 4K@60Hz with HDCP 2.2 compliance. Balanced and unbalanced analog audio is de-embedded via a 5-pin phoenix connector for integration with existing speaker systems. Three downstream USB device ports on each unit support webcams, PTZ cameras, keyboards, mice, and touch panels. RS-232 pass-through enables third-party control system integration, while FSYNC GPIO provides industrial camera synchronization. Bi-directional 24V PoC allows flexible power deployment at either end of the cable run.

Questions
- What USB and HDMI standards does the EXT-USBCPD2X4K-100M support?
- USB 3.2 Gen 1 at up to 5Gbps and HDMI 2.0b output at up to 4K@60Hz with 18Gbps video bandwidth and HDCP 2.2 compliance.
- What color depth and color space does the HDMI output support?
- 8/10/12-bit color depth across RGB, YCbCr 4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 color spaces.
- How do I connect the audio output for a sound system?
- Use the RX's 5-pin Phoenix AUDIO OUT connector, wired L+/L-/GND/R+/R- for balanced output (max 2Vrms) or L+/GND and R+/GND for unbalanced output (max 1Vrms), carrying de-embedded LPCM 2CH audio at 32-192kHz.
- How do I switch between the two USB-C host inputs?
- Press the front-panel Host Switch button, or send the API command "set input 1" or "set input 2"; auto-switching (default on) selects the active host automatically by detecting USB 5V.
- What power supply does the EXT-USBCPD2X4K-100M ship with?
- A DC 24V/7.5A locking power supply (AC 100-240V 50/60Hz input) is included. Note that the transmitter's DC 24V input port is documented as 24V/7.5A while the receiver's DC 24V input port is documented as 24V/3.75A in the panel descriptions.
- What are the dimensions and weight of the TX and RX?
- Both units measure 180mm x 95mm x 23mm (7.09 in x 3.74 in x 0.91 in); the TX weighs 482g (1.06 lb) and the RX weighs 486g (1.07 lb).
- There is no video on the connected displays. What should I check?
- Ensure the latest Synaptics DisplayLink driver is installed, use HDMI cables no longer than 3m, and confirm the LINK LED is illuminated on both TX and RX.
- USB devices are not detected at the RX. What should I check?
- Verify the USB LED is on or blinking, use a direct CAT6a cable (T568B to T568B), and check that the cable run does not exceed 100m.
- What makes the EXT-USBCPD2X4K-100M suited for a BYOD conference room?
- It combines dual-host USB-C switching, up to 100W PD laptop charging, and dual 4K@60Hz HDMI outputs with audio de-embedding over a single 100m CAT6a run, supporting two-laptop redundancy or presenter handoff.
- What control integration does the EXT-USBCPD2X4K-100M offer?
- RS-232 pass-through on both TX and RX plus a full ASCII API accessible via the SERVICE or RS-232 port, for integration with third-party control systems.
