The SXP-320A is an interface converter that allows Centronics and RS-232 devices to communicate with each other (a computer with an RS-232 output to a Centronics Parallel printer, for example). The unit is reversible enabling you to convert from serial to parallel or parallel to serial. These two-way converters provide a DB-25 RS-232C (DCE) compatible connector, and a C-36 Centronics connector. The serial baud rate is from 1200 to 115200 bps. (selectable by DIP Switch). The parallel interface speed for the SXP-320A is 11.52 KB/sec. The units support both hardware and software (XON/XOFF) handshaking. Setup is extremely easy. All that is involved is setting the DIP Switch and connecting the cables.
