USB to RS422/RS485 adapters w/Optical Isolation (FULL SPEED)
Description Our Optically Isolated USB to RS422/RS485 adapters are an easy way to connect RS422 or RS485 devices to a USB port on your computer. The isolation circuit provides an optical barrier between your computer and the RS422/RS485 bus connected to the unit, protecting the computer from harmful spikes and surges which may occur on the bus. The unit also features built-in surge protectors to further protect against spikes, surges and electrostatic discharge which may occur on the RS422/RS485 side. Each port can be set as RS422 or RS485 allowing devices using either of these protocols to be connected. Each port has options such as termination and biasing and indication LEDs for Tx and Rx for easy diagnostics. With their increased protection against spikes and surges, combined with a variety of port numbers and enclosure styles and easy to install drivers for a range of operating systems, these robust adapters are ideal for adding one or more RS422/RS485 ports to your computer.
