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 serial interfaces. To connect these devices to modern PCs, you
need a simple and reliable conversion solution.
The USOPTL4DR-xx series offers this solution. Specifically designed for
industrial applications, they offer 3000V optical isolation with 15 KV ESD
protection. The slim-line DIN rail mountable enclosure has a small footprint and,
since it draws power from your computer’s USB bus, an additional power supply
is not required. Simply plug the converter into an available USB port on your
computer or USB hub and install the drivers supplied on CD ROM. The device
will show up as an additional COM port in the Windows Device Manager which is
fully compatible with your Windows applications.
One and two port versions are available. The single port version is also available
with a “locked serial number” that allows you to interface your PC with multiple
converters without having to load a driver for each one - perfect for field service
applications. 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.
