RS232 to RS422/RS485 converter, mini
Mini in-line RS232 to RS422/RS485 converters. Converters are powered from the RS232 port (RTS and/or DTR signals). The converters are available with sub-D 9-pole connector or terminal screw block on the RS422/RS485 side. Some software applications need a "Auto turn Around" converter for a 2-wire half-duplex RS485 bus.
