In-line USB Converters
USOPTL4, USPTL4, USO9ML4
Models USOPTL4, USPTL4 and USO9ML4 are USB to one port RS-422/485
converters. Supporting 2-wire RS-485 or 4-wire RS-422/485 communications,
these devices are great for applications requiring long range or multi-drop
capabilities. High retention USB port holds standard USB cables tight.
Models USOPTL4 & USO9ML4 include circuitry with 2000 Volts isolation to
protect against ground loops and voltage spikes. Models USOPTL4 and USPTL4
use pluggable terminal blocks on the RS-422/485 side while Model USO9ML4
uses a DB9 connector on the RS-422/485 side. Two LEDs indicate data transmit
or receive. The converters draw power from the USB port so no power supply is
required.
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 show ups as an
additional COM port in the Windows Device Manager, and is compatible with
Windows applications.
Universal Serial Bus (USB)
USB has become the connectivity workhorse of today’s PCs, replacing classic
serial ports. But, many commercial and industrial devices still use RS-422/485
interfaces. To connect these devices to modern PCs, you need robust and
reliable conversion solutions. USB ports are becoming more common on
commercial and industrial equipment such as point-of-sale peripherals, medical
devices, scientific instrumentation, laboratory equipment and other devices or in
environments where surges, spikes and ground loops are likely to occur.
RS-485 Control
No special software is required to control the RS-485 receiver or transmit line
driver. The driver is automatically enabled during each byte transmitted in RS-
485 mode. The transmitter is always enabled in RS-422 mode. The receiver
is tri-stated during each byte transmitted in the echo-off mode. The receiver is
always enabled in the echo-on mode. There are 4.7k Ohm pull-up/pull-down
resistors on the RDA and RDB lines. A termination resistor may be added to R16
if needed. See the B+B Smartworx RS-422/RS-485 Application Note (available
on our website) for more information on termination and DC biasing of an RS-
485 network.

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.
