RS-232 to RS-422/RS-485 Converter

Small modules that convert single-ended RS-232 signals into differential RS-422 or RS-485 signals. Signal conversion is completely bidirectional - outgoing RS-232 signals are converted to RS-422/RS-485 differential levels and incoming RS-422/RS-485 differential signals are converted into single ended RS-232 signals.

The Converter has a DB-9 female connector on one end that mates to the DB-9 male connector found on the rear of most PCs and other serial devices. Besides its use with PC's,Converters can be used with any 9-pin RS-232 device whose pinout matches that of a PC's COM port.

Once equipped with the Converter, the PC or RS-232 device can communicate with other RS-422 or RS-485 devices.

1. Convert single ended RS-232 signals to RS-485 or RS-422 differential signals.
2. Bidirectional data transfer with increased noise rejection.
3. Overcomes RS-232's 50 foot cable limit to Extend RS-232 transmission distance.
4. Adds multi-drop capability to an RS-232 signal. Drives up to 50 loads.
5. Meets FCC Class A and European CE requirements.
