BB-USPTL4 ADVANTECH RS 422 485 over usb

Models USOPTL4 and USPTL4 are USB to one port rs422/485 converters.
Supporting 2-wire rs485 or 4-wire rs422/485 communications, these
devices are great for applications requiring long range or multi-drop
capabilities. Both models use pluggable terminal blocks on the rs422/485
side. Two LEDs indicate data transmit or receive. Model USOPTL4 includes
circuitry with 2000 Volts isolation protection against ground loops and
voltage spikes. Both products draw power from the USB port so no power
supply is required.
