Compact CAN Adapter for USB Hosts

This CoolGear CG-1PMGICAN adapter adds a CAN bus port to any computer with a USB 1.1, 2.0 or 3.0 socket. It runs from bus power and installs as a standard Windows COM port without extra drivers.

Fits Desktop or Bench Use

The SECC metal chassis measures 61mm × 50mm × 23mm and connects through a DB9 plug. Galvanic isolation rated at 2500V and ±16kV ESD protection shield the host from stray currents on the CAN network.

Upgrades Basic USB-to-Serial Links

It replaces simple USB-to-RS-232 converters when CAN 2.0A or 2.0B framing is required. The ARM Cortex-M0 controller handles speeds up to 1Mbps and 512-byte transmit buffers, so the step up is worth it for diagnostics or automation that need native CAN frames.

Questions about this item

What CAN bus speed limit appears first when the CG-1PMGICAN runs continuously?

The adapter supports up to 1 Mbps on the CAN bus, and that ceiling is the first throughput limit reached under sustained load.

How much power does the CG-1PMGICAN draw and how hot or loud does it get when left running all day?

It is powered entirely from the USB port with no external supply, has no fan, and the metal chassis passively dissipates heat, so it runs silently and stays cool during continuous use.

Which cable or connector must I already have to attach a CAN device to the CG-1PMGICAN?

The adapter presents a DB9 connector, so you need a DB9-terminated CAN cable or a DB9-to-terminal-block adapter that matches your CAN network wiring.
