CG-1PRTMCAN USB to CAN Bus Adapter

The CG-1PRTMCAN connects to a USB 1.1, 2.0 or 3.0 port and adds a single CAN bus channel with a DB9 connector. It draws power directly from the USB bus so no external adapter is required. A 32-bit ARM Cortex-M0 microcontroller handles the CAN controller and the USB-to-UART bridge. Drivers are supplied for Windows and Linux and the device installs as a standard serial port.

Engineers adding CAN to a laptop or industrial PC

Developers who need a portable, bus-powered CAN 2.0A/2.0B interface for diagnostics, data logging or ECU simulation will find the plug-and-play operation and ASCII command API practical. The single channel and 1 Mbps ceiling mean it is not suited for multi-channel logging or high-speed automotive networks that exceed the stated rate.

1 Mbps CAN 2.0A/2.0B with 512-byte FIFO

The adapter supports the full CAN 2.0A and 2.0B standards at up to 1 Mbps and provides a 512-byte transmit/receive FIFO buffer for sustained throughput. This speed and buffer combination determines whether the link can keep up with the target bus load without frame loss.

Questions about this item

What does the 1 Mbps CAN bus speed mean when the adapter is connected to a real machine?

The adapter can transmit and receive CAN frames at up to 1 Mbps, limited by the bus load and the 512 byte FIFO buffer on the ARM Cortex-M0 controller.

Which USB standard does the CG-1PRTMCAN use and what throughput does that cap in practice?

It connects via USB 1.1, 2.0 or 3.0 ports and is powered from the bus; the USB link itself does not restrict the 1 Mbps CAN rate.

What physical mounting or space does the metal-cased adapter need to fit?

The unit has a DB9 male connector for the CAN bus and a standard USB plug; it requires only a free USB port and clearance for the DB9 cable.
