Product Description

The SXP325 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. The SXP325 is configured with 512KB of memory allowing it to serve as a printer buffer. 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, which is selectable by DIP switch. The parallel interface speed for the SXP325 is 1.5 MB/sec. The unit supports both hardware and software (XON/XOFF) handshaking. Setup is extremely easy. All that is involved is setting the DIP switch and connecting the cables.

This review is from: Aten Technologies SXP325 Serial to Parallel Bi-Direction Converter with 512KB Buffer (Personal Computers)

I have a scope/logic analyzer product that makes hardcopy of measurement over a GPIB I/O to a printer. It also supports output over an RS232c I/O through a DB25 connector. This SxP325 serial to parallel converter converts the serial I/O to the centronics parallel protocol of the new printer. Make sure the replacement printer is compatible with the I/O protocol of the original! The new PCL5 protocol was upward compatible with the old PCL protocol. The 1st SxP325 didn't work and I contacted Aten about the problem. I returned the defective product and 1 week later got a replacement that worked. It can work with either software (xon/xoff) or hardware handshaking at 8 different baud rates. It plugged into the printer and a custom serial cable was made to match the serial output pin assignment with the serial input assignment to the SxP325.
