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-x 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.

INFORMATION – FCC RULES

This device complies with Part 15 of the FCC rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference that may cause undesired operation.

TERMINAL BLOCK

The terminal block layout is top to bottom (as viewed
from a DIN rail installation). The signal names on the front
label are only visible when the terminal block is removed.
The USOPTL4DR-2 has two terminal blocks. In both
configurations, the TB layout is the same.
