The RS-232 to RS-422/485 serial converters are compact and tough. Each model is designed and tested to meet heavy industrial EMC standards. The RS-232 signal is connected through a female DB9 connector. The RS-422/485 (2-wire and 4-wire) signal is connected through a five-position removable terminal block, making wiring easy. Power is connected through a two-position removable terminal block. Our bit-wise-enabled circuitry automatically detects the character time-out, eliminating the need to set DIP switches for the baud rate.
