Name: 5Gbps Dual-Host USB-C Extender over CAT6a (100m/328ft) with Dual 4K HDMI Out
Brand: KanexPro
SKU: EXT-USBCPD2X4K-100M

Question 1

How do I send API commands to the extender?

Accepted Answer

Connect the SERVICE (USB-C) or RS-232 Phoenix port (pin 1 TX, pin 2 RX, pin 3 GND) to a PC, open a serial terminal at 115200 baud, 8N1, and type "help" or "?" to list all commands, for example "get status" for a full system status report.

Question 2

How much USB-C Power Delivery does the transmitter provide?

Accepted Answer

Up to 100W total, either as 1x100W to a single host or 2x50W when charging two connected hosts simultaneously; charging requires the TX to be powered from its external power supply, not via PoC.

Question 3

What audio formats does the EXT-USBCPD2X4K-100M carry?

Accepted Answer

Up to LPCM 2.0/5.1CH over HDMI, plus analog de-embedded LPCM 2CH audio (32-192kHz) via the RX's 5-pin Phoenix audio output.

Question 4

How do I connect the audio output for a sound system?

Accepted Answer

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.

Question 5

What are the dimensions and weight of the TX and RX?

Accepted Answer

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).

Question 6

What cable connection method does the CAT6a run require?

Accepted Answer

Direct T568B-to-T568B interconnection; do not cross-connect the cable.

Question 7

There is no video on the connected displays. What should I check?

Accepted Answer

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.

Question 8

USB devices are not detected at the RX. What should I check?

Accepted Answer

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.

Question 9

What control integration does the EXT-USBCPD2X4K-100M offer?

Accepted Answer

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.

Question 10

What industrial or specialty use case does the FSYNC port support?

Accepted Answer

FSYNC GPIO pass-through (default 0-5V) enables frame-synchronized industrial camera deployments across the extension link.
