Universal Serial Bus (USB) has become the connectivity workhorse of today’s
PCs, replacing the familiar serial port. 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 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.
