$49.95 In stock

The surge and static protected MWE820A is a port powered small and convenient USB to RS485 / RS422 Mini adapter with no need for external power supply. This converter is made with the high performance and very reliable CP2102 chip from Silicon Labs.
This USB to RS485 / USB to RS422 adapter is suitable for most applications, including industrial, commercial and any general office computer device. It is a bi-directional, (meaning it communicates in both directions), reliable and cost-effective converter that easily lets you connect any RS485 or RS422 device directly to your computer's USB port, efficiently converting USB signals to half-duplex RS485 or full-duplex RS422 and vice versa.
This USB to RS485 / USB to RS422 adapter is powered from the USB port so no external power supply is needed. The RS485 / RS422 end is a standard 4-terminal screw header for easy connection of single wires.
Automatic send data control is enabled by default so no external flow or handshake control is needed.
It can be used in point to point or point to multipoint networks with up to 32 nodes. The typical communication distance is up to 9800 FT (3km) at 4800bps and 6500 FT (2km) at 9600bps. It support with Windows, Linux and Mac.
