Up to 12 Mbit/s

Adapter tags CAN messages with time-stamps

Suburban Embedded (USA) released the Hadou‑CAN open-source CAN-FD-to-USB adapter with the PPS-based (pulse-per-second) Tymesync feature.

The company develops solutions for autonomous control in vehicles and globally-interacting systems. The adapter supports bit-rates of up to 1 Mbit/s for Classical CAN networks. In the data phase of the CAN FD network up to 12 Mbit/s are possible. 11‑bit and 29‑bit CAN identifiers can be used. The USB interface is realized as the USB 2.0 type B device. The 9‑pin D-sub connector is used on the CAN side. Jumper connectors are used to add and to remove termination resistors for the CAN network. Blue extruded-aluminum device‑housing is offered as an option. The USB ground is isolated from the CAN ground to protect the used equipment. The electrically isolated CAN side protects a computer used in high-power robotics applications, in distributed networks with a large ground offset, or in applications with a high common mode noise. Automatic slew-rate control functions care for low EMI (electromagnetic interference) and provide advantages for high‑speed applications.

The implemented PPS Timesync input/output allows to tag CAN messages with time‑stamps. This provides a common time base for received CAN traffic between multiple networks or external systems. Bootloader for loading of customized user programs is available. The adapter uses the Lawicel text-mode protocol and is compatible with Slcan on Linux. Supported operating systems include Linux, Windows 7, and Windows 10. The device can be ordered from Digikey.
