Four-Port RS232 Adapter for Laptop Users

This USB-to-serial adapter adds four RS232 ports to a laptop or desktop through a single USB connection. It is aimed at engineers, technicians and hobbyists who need to control multiple legacy devices such as routers, GPS units, programmers, printers, scanners, modems, cameras or PDAs from a modern computer without native serial ports.

Driver Install Then Plug In

Install the supplied driver for Windows XP, Vista, 7, 8, 10 (32-bit or 64-bit) or OS X before connecting the hardware. The COM reserve feature keeps port assignments after reboots, avoiding the common issue of ports shifting numbers. Power comes from the USB bus so no external adapter is required; a frequent mistake is forgetting to install the driver first, which leaves the ports invisible to the operating system.

Check OS and Port Needs Before Buying

Verify that your target devices use standard RS232 signalling and that your operating system appears in the supported list. The adapter provides exactly four serial ports; setups requiring more than four simultaneous connections will need additional hardware. Ensure a free USB port is available for the included data cable.

The box contains the adapter and one USB data cable; you must supply your own RS232 cables for each of the four serial devices you want to attach.

Which operating systems are officially supported for the 32-bit and 64-bit versions?

The adapter works with Windows XP, Vista, 7, 8, 10 (both 32 and 64 bit) and OS X; choose the driver that matches your OS version during installation.
