KH-UCANFD-PRO-X4U Compact Four Channel USB to CANFD Analyzer 3000V Electrical Isolation with DB9 Interface

Introduction:
- KH-UCANFD-PRO is the metal-enclosure USB CAN / CAN FD adapter family powered by CANmeleon. The current documented P/Ns are KH-UCANFD-PRO-X2U and KH-UCANFD-PRO-X4U, with two and four independent channels respectively.
- The 3000V isolation specification on this page applies to the current documented X2U / X4U products. For an earlier delivered unit, confirm its P/N and the specification supplied with that unit before applying these figures.
- The PRO series has a metal enclosure, protective end caps and two DB9 connectors. Each X2U connector carries one channel; each X4U connector carries two channels.

Highlights:
- Two channels, one DB9: One compact connector carries CAN1 and CAN2.
- 12Mbit/s CAN FD: Both channels support full-rate operation.
- Built-in termination: Switch with the user button and confirm with RES LEDs.
- 1500 V isolation: Separates the host from the CAN network.
- Compact enclosure: 86.0 x 42.5 x 20.5mm with integrated USB-A cable.

ISO and Non-ISO CAN FD:
- ISO CAN FD and the earlier Non-ISO CAN FD format are not fully compatible. X2U and X4U support both modes; the adapter, target nodes and host software must use matching modes, rates and sample points.
- CAN FD supports classical CAN 2.0A/B communication, but CAN FD extensions cannot be used on a classical CAN network.

Typical Applications:
- Synchronized acquisition, diagnosis and replay on multiple CAN FD buses.
- Vehicle and controller debugging, including BMS, VCU and chassis networks.
- Robot and industrial-network debugging.
- High-load CAN FD acquisition and stress tests.
- Automated test benches, production validation and long-term recording.
