Port 1 utilises a DB9 (9-pin) female connection type and port 2 uses a terminal block, where wires are clamped down using screws for a secure connection. Between the 2 ports combined, they allow every type of serial device to be connected; RS232, RS422, and RS485 included.

How do I configure the ports?This converter features a DIP switch that makes it a cinch to manage the settings of the ports.

StarTech's converter is suitable for an office or industrial environment as it comes with a wall mounting bracket for simple and convenient installation right out of the box. The adapter is also powered by the USB connection to reduce the amount of wiring in the workplace. There is the option for an external power adapter should your device need power beyond what the host connection can provide.

The USB connection is backwards compatible from version 1.1, allowing users to save on upgrading costs and continue using legacy cables. This part of the converter includes a hard-wearing screw-lock to make sure cables aren't disconnected unexpectedly.
