USB to RS422 / RS485 Standard

$39.95 In stock

This standard USB to RS422 / RS485 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 RS422 or RS485 device directly to your computer's USB port, efficiently converting USB signals to half-duplex RS485 signals and full-duplex RS422 signals and vice versa. It is build around the PL-2303HX processor chip from Profilic which is a good allround processor for general use.
This USB to RS422 / RS485 adapter is powered from the USB port so no external power supply is needed. The RS422 / RS485 end is a standard 9-pin D-sub connector with a optional screw terminal board included for easy connection of cables or single wires.
Automatic send data control is enabled by default so not external flow or handshake control is needed.
Drivers for this USB to RS422 / RS485 adapter are fully compatible with Windows 98Se, ME, 2000, XP, Server 2003, Mac and Linux but has only limited compatibility with Windows 7 and Vista, (click here for our Premium USB to RS422 / RS485 adapter which is optimized and fully compatible with Windows Vista and Windows 7).
