Models USOPTL4 and USPTL4 are USB to one port RS-422/485 converters. Supporting 2-wire RS-485 or a 4-wire
RS-422/485 communications, these devices are great for any application that requires long range or multi-drop
capabilities. Both models use pluggable terminal blocks on the RS-422/485 side and have a pair of LEDs that indicate
data being transmitted or received. Model USOPTL4 includes special circuitry that adds 2000 volts isolation protection
against ground loops and voltage spikes. Both products draw power from the USB port so no power supply is required.
Simply plug the converter into an available USB port on your computer or USB hub and the device will show up as an
additional COM port in the Windows Device Manager. Configured as an additional COM port, the converter is now
compatible with your Windows applications.
Universal Serial Bus (USB) has become the connectivity workhorse of today's PCs, replacing the familiar 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. At the same time, 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. Sometimes these are used in environments where surges, spikes and ground
loops are likely to occur.
