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
485USBTB-2W and 485USBTB-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. Select the 485USBTB-2W
for RS-485 2-wire applications or the 485USBTB-4W for RS-485 4-wire
applications. Locked serial number versions are also available (see the
installation notes in the driver section). A 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.
