Dual-Host USB 3.2 Gen 1 Extender over CAT6a — USB-C & USB-B Inputs, 100m/328ft
KanexPro EXT-USBC2XI-100M is a USB 3.2 Gen 1 TX/RX extender kit with selectable USB-C and USB-B host inputs, extending 5Gbps USB up to 100m/328ft over…
Most USB extension deployments force a choice: commit to a modern USB-C host or keep the legacy USB-B controller — but not both. The KanexPro EXT-USBC2XI-100M eliminates that compromise by accepting both a USB-C and a USB-B host on the transmitter, with selectable auto or manual switching, so integrators can serve mixed-generation environments over a single 100m/328ft CAT6a run without adapters, workarounds, or a second extender in the rack. Built for 24/7 industrial, medical, and institutional deployments, the EXT-USBC2XI-100M delivers USB 3.2 Gen 1 at 5Gbps over CAT6a (F/FTP) to a four-port device cluster at the receiver — 3× USB-A and 1× USB-C — while bi-directional 24V PoC keeps cabling minimal by eliminating the need for local power at the remote end. RS-232 pass-through and FSYNC GPIO support extend automation and synchronized camera control across the full link, making this TX/RX kit equally at home in a factory vision system, a medical cart deployment, or a security workstation.
- USB 3.2 Gen 1 extension at 5Gbps over a single CAT6a (F/FTP) cable up to 100m/328ft — no signal degradation over long runs in EMI-prone environments
- Selectable USB-C and USB-B host inputs on the transmitter with auto and manual switching — bridges modern and legacy host systems without adapters or cable swaps
- Four-port device cluster at the receiver (3× USB-A + 1× USB-C) — supports mixed peripheral deployments including cameras, touch panels, keyboards, and storage
- Bi-directional 24V PoC over CAT6a — eliminates the need for a local power outlet at the receiver, simplifying installation in remote or space-constrained locations
- RS-232 pass-through with 3-pin phoenix connector — integrates legacy serial control devices and automation controllers across the full extension link
- FSYNC GPIO pass-through — enables frame-synchronized industrial camera deployments and multi-sensor automation systems without a separate sync cable run
- Auto and manual host switching modes — supports hands-off failover in unmanned installations or precise operator control in active switching environments
- Dedicated SERVICE port (USB-C) on both TX and RX for in-field firmware updates — keeps deployed systems current without physical recall or bench service
- Plug-and-play operation with no drivers required — supports rapid deployment across Windows, macOS, Linux, and industrial controller environments

Questions
- What USB standard and data rate does the EXT-USBC2XI-100M support?
- USB 3.2 Gen 1 (SuperSpeed) at up to 5Gbps, backward compatible with USB 2.0 and USB 1.1.
- What is the maximum extension distance and required cable type?
- 100m/328ft over CAT6a (F/FTP) shielded cable; the local USB cable run at each end is limited to 1.5m/4.9ft.
- How do I switch between the two host inputs?
- Press the front-panel Host Switch Button to toggle between HOST 1 (USB-C) and HOST 2 (USB-B), or hold the button for 3 seconds to toggle auto-switch mode; via API, send "set input 1" for HOST 1 or "set input 2" for HOST 2, and "set autoswitch on" or "set autoswitch off" to control automatic detectio
- How do I access the API command interface?
- Connect the SERVICE (USB-C) or RS-232 (3-pin Phoenix, pin 1 TX / pin 2 GND / pin 3 RX) port to a PC and open a serial terminal; the SERVICE port is fixed at 115200 bps while the RS-232 port is configurable from 4800-115200 bps (default 115200), 8N1. Type "?" to list all commands.
- What power supply does the EXT-USBC2XI-100M ship with?
- Per the product manual's specifications table and package contents, a DC 24V/3.75A multinational locking power adapter (AC 100-240V 50/60Hz input).
- What are the dimensions and weight of the TX and RX?
- Both units share identical dimensions of 140mm (W) x 75mm (D) x 23mm (H) (5.51 in x 2.95 in x 0.91 in); the transmitter weighs 313g (0.69 lb) and the receiver weighs 318g (0.70 lb).
- No USB devices are detected at the receiver. What should I check?
- Confirm the CAT6a cable is connected to HDBT-USB3 on both TX and RX with the LINK LED solid on both units, verify USB 5V is present on the active host with "get usb5v 0", and use direct point-to-point cable routing only, with no switches, patch panels, or couplers in the path.
- The USB link falls back to USB 2.0 speed. What should I check?
- Confirm CAT6a F/FTP shielded cable is in use, since unshielded cable may degrade to USB 2.0 at 100m, verify no couplers or patch panels are in the run, and check the USB LED, which is solid for USB 3.0 and blinking for USB 2.0.
- Why choose the EXT-USBC2XI-100M over a single-host USB extender?
- Its selectable USB-C and USB-B host inputs with auto or manual switching let one receiver-side peripheral set serve either a modern USB-C laptop or a legacy USB-B host without adapters or cable swaps.
- What deployments benefit from the EXT-USBC2XI-100M's FSYNC and RS-232 features?
- Industrial camera installations needing frame-synchronized multi-sensor automation, and control systems requiring RS-232 pass-through or full ASCII API command control across the extension link.
