B&B ELECTRONICS
Isolated USB to 2 or 4 Port RS-422/485
Models: USOPTL4-2P & USOPTL4-4P
Functional Description
Connect RS-422 and RS-485 (2-Wire and 4-
Wire) devices to a USB port and gain 2000 V
RMS Isolation from voltage spikes and ground
loops. 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-422/485 interface. To connect
these devices to modern PCs and provide
protection from electrical transients, you need a
simple and reliable conversion solution. The
USOPTL4-2P and USOPTL4-4P offer this
solution and are great for any application that
requires long range or multi-drop capabilities.
Both models offer a high retention USB
interface, removable terminal blocks on the
serial side and have LED’s to indicate data
flow. 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 additional
COM ports in the Windows Device Manager,
which are fully compatible with your Windows
applications. A one meter USB cable is
included.
