KH-UCANFD-X2I — 2-Channel Industrial USB CAN FD Adapter
Chengdu Kunhong Electronic Technology Co., Ltd.
Product Overview
KH-UCANFD-X2I is a 2-channel industrial USB CAN FD adapter in the CANmeleon family. It expands a computer, industrial PC or robot controller with two CAN / CAN FD channels and is designed for industrial automation, robotics, field debugging, fixed test stations and long-term deployment.
Unlike portable LITE and PRO adapters, X2I uses an aluminum enclosure with mounting holes, pluggable CAN terminal blocks, termination DIP switches, a side button and clear front-panel status indicators.

Terminal Pinout
| Channel | Signal | Description |
|---|---|---|
| CAN1 | GND | Channel 1 reference ground |
| CAN1 | CAN1H | Channel 1 CAN High |
| CAN1 | CAN1L | Channel 1 CAN Low |
| CAN2 | GND | Channel 2 reference ground |
| CAN2 | CAN2H | Channel 2 CAN High |
| CAN2 | CAN2L | Channel 2 CAN Low |
The terminal can be supplied as one 6-pin block or two 3-pin blocks. Confirm CAN_H, CAN_L and GND before applying power.
Termination
| DIP switch | Channel | Function |
|---|---|---|
| 1 | RES1 / CAN1 | Enables channel 1 termination |
| 2 | RES2 / CAN2 | Enables channel 2 termination |
Enable the 120 Ω termination only when the adapter is at the corresponding end of the bus. Do not add extra termination at a middle node.
Button
Press and hold the button for about 3 seconds to switch firmware / protocol application. Keep USB power stable during switching, and avoid repeated button presses or disconnecting power.
Note: When the device is in use by software, including CANmeleon Device Manager, the device button is disabled to prevent accidental activation during operation.
