KH-UCANFD-LITE-X2U Compact Dual Channel USB to CANFD Analyzer 1500V Electrical Isolation with DB9 Interface

Introduction:
- KH-UCANFD-LITE-X2U connects two CAN / CAN FD networks to a computer or industrial PC through USB-A. Both channels share one DB9 connector and can be separated with a terminal adapter or one-to-two DB9 Y cable.

- This page describes the current documented KH-UCANFD-LITE-X2U P/N. Enclosure dimensions follow the dimensioned drawing in the Interfaces section.

- The adapter provides 1500 V electrical isolation, up to 12Mbit/s in the CAN FD data phase, 64-byte CAN FD payloads and backward compatibility with CAN 2.0A/B. Both channels can operate at full bus load simultaneously.

- The integrated USB-A cable is 0.8 m long and UL-certified. A button switches the internal termination resistors, and each channel has independent multi-color status indication. The operating temperature is -40 to +85 °C; IEC 61000-4-2 ESD protection is ±15kV air discharge and ±8kV contact discharge.

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. All nodes on a bus must use the same mode. KH-UCANFD-LITE-X2U supports both modes.

Typical Applications:
- Automotive electronics, industrial automation, robotics, motor control and electric-drive development, debugging and diagnosis.

Technical Specifications:
- Two CAN / CAN FD channels through one DB9 connector.

- Arbitration rate: 25kbit/s to 1Mbit/s
- Data-phase rate: 25kbit/s to 12Mbit/s
- Both channels can operate at maximum bus load simultaneously.
- CAN FD payload up to 64 bytes.
- 11-bit standard and 29-bit extended identifiers.
- Hardware timestamp resolution approximately 1μs.
- Bus-load measurement, error-frame detection and state monitoring.
- 1500V electrical isolation.
- Two built-in 120Ω termination resistors.
- Dimensions: 86.0 x 42.5 x 20.5 mm
- Operating temperature: -40 to +85°C
- IEC 61000-4-2 ESD: ±15kV air discharge, ±8kV contact discharge
- For Windows, Linux, macOS, SocketCAN and python-can.
- Ensure the adapter, target nodes and host software use the same CAN FD mode, arbitration rate, data rate and sample points.
