USB-CAN Adapters

USB-CAN Adapter

Two-in-one: CANopen master | USB-CAN bridge

An amphibious USB-CAN adapter. On one side it embeds a CANopen master: with the WD servo debugger host software (Windows / Linux / macOS) you can scan nodes, configure parameters, enable the servo, and control position / velocity / torque of WD servo motors (CiA402). On the other side it works as a general USB-CAN bridge, plug & play on Linux and Windows, and compatible with the open-source CANgaroo software.

Function 1: CANopen master
Function 2: USB-CAN bridge
Interface: USB 2.0 + CAN 2.0B
Baud rate: 50 kbps … 1 Mbps

01 Features & Advantages

Why choose USB-CAN Adapter

01
CANopen master: full NMT / SDO / PDO / EMCY support
02
CiA402 servo control: node scan, parameter configuration, enable, jog and homing
03
CANopen master mode: cross-platform servo debug & monitoring in one tool — WD servo debugger
04
USB-CAN bridge mode: plug & play on Linux and Windows, works with the CANgaroo open-source software
05
Desktop-class: debug WD motors, also works with standard CANopen devices
