Isolated USB 2 or 4 Port RS-422/485 Converters

USOPTL4-2P & USOPTL4-4P

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.
