485USB9F-2W & 485USB9F-4W

Universal Serial Bus (USB) has become the connectivity workhorse of
today’s PCs, replacing the familiar serial ports. However, many commercial
and industrial devices still use the RS-485 interface. To connect these
devices to modern PCs, you need a simple and reliable conversion solution.
The 485USB9F-2W and 485USB9F-4W offer this solution in a space saving,
USB Port powered package.

Simply install the drivers supplied on CD ROM and plug the converter into
an available USB port on your computer or USB hub. The device will show
up as an additional COM port in the Windows Device Manager which is fully
compatible with your Windows applications. Choose the 485USB9F-2W
for RS-485 2-wire applications or the 485USB9F-4W for RS-485 4-wire
applications. Locked serial number versions are also available. A one meter
USB cable is included.

locked Serial numbers explained

We configure our single-port USB to serial converters in two ways. In

standard format, each product has a unique serial number. “Locked serial”

format uses the same serial number that is associated with a model type.

If your converter will always be used with the same computer, the standard

serialized model is all you need. If the converter is shared among several

computers, like field service laptops, the locked serial number model lets

you plug and play without having to worry about matching the two.
