Overview

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.

Key features
  • Extends USB 3.2 signals at 5Gbps up to 100m/328ft over a single CAT6a cable via HDBaseT
  • Dual USB-C host inputs on TX with auto/manual switching — supports two-laptop redundancy or presenter handoff
  • USB-C PD charging up to 100W (1×100W or 2×50W) — powers laptops directly from the transmitter
  • Dual HDMI 2.0b outputs on RX at up to 4K@60Hz — mirror or extend displays with HDCP 2.2 compliance
  • Balanced and unbalanced analog audio de-embedding on RX (LPCM 2CH, 32–192kHz) via 5-pin phoenix connector
  • Three downstream USB device ports on each unit (1× USB-C + 2× USB-A) for webcams, PTZ cameras, keyboards, and touch panels
  • RS-232 pass-through on both TX and RX for third-party control system integration
  • FSYNC GPIO pass-through for industrial camera synchronization (default level range 0–5V)
  • Bi-directional 24V PoC — power either TX or RX, the other unit is powered over the CAT6a link

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.
