Industrial RS485 Link

This USB to RS485 converter adapter connects a standard USB 2.0 port to RS485 industrial devices without external power. It targets engineers, technicians and hobbyists who configure PLCs, PTZ cameras, access-control panels or other RS485 equipment from a laptop or desktop. The black dongle draws power directly from the USB bus and supports hot-swap on the USB side.

Host Compatibility Check

Verify that your computer runs Windows XP, Vista, Windows 7, Linux, MacOS or WinCE 5.0 and provides a free USB 2.0 or 1.1 port. Confirm the RS485 device uses standard A/B wiring or D+/D- labelling so the adapter terminals match. Ensure the application can operate within the 75 bps to 115 200 bps range, with a maximum of 6 Mbps, and that the 1.2 km distance limit suits the installation.

Plug-and-Play Practicality

No driver CD or external power supply is bundled; the adapter relies on the host OS to recognise the virtual COM port. The built-in LED indicators show TX/RX activity, letting you verify communication immediately. Its compact 6.1 × 1.6 × 1.3 cm form factor and industrial temperature rating of -40 °C to +85 °C mean it fits in tight cabinets and survives harsh environments without extra accessories.

Questions about this item

What comes in the box and do I need to buy a separate cable for the RS485 side?

The adapter has a USB plug for the PC and an RS485 port for the device; no external power supply is required because it draws power from the USB port. The RS485 wiring (A to A, B to B) must be supplied by the installer.

Which operating-system version should I pick for the driver?

Drivers are provided for Windows XP, Vista, 7, Linux, MacOS and WinCE 5.0; choose the one that matches the OS running on the host machine.

What does the 115200 bps baud-rate figure mean when the adapter is connected to a real RS485 device?

The hardware supports baud rates from 75 bps up to 115200 bps, with a maximum of 6 Mbps, so 115200 bps is a standard high-speed setting well within the supported range for typical industrial equipment.
