Isolated USB 2 or 4 Port RS-232 Converters
USO9ML2-2P & USO9ML2-4P
Connect legacy RS-232 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-232 interface. To connect these devices to modern PCs and
provide protection from electrical transients, you need a simple and reliable
conversion solution. The USO9ML2-2P and USO9ML2-4P offer this solution.
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.
