CONNECTING THE 232SPS2 TO YOUR PARALLEL PORT
The 232SPS2 uses most of the available pins on the parallel
port. To insure proper operation, you should use a cable that
connects all 25 pins from connector to connector. B&B's Model
232AMM5 is recommended. For detailed information on which pins
are connected on the parallel port, refer to Appendix A.
CONNECTING THE 232SPS2 TO YOUR SERIAL PRINTER
The connections required between your 232SPS2 and your
serial printer depend on the type of flow control used. There are two
kinds of flow control, XON/XOFF control and hardware handshaking
control. Dipswitch position #4 must be "OFF" for XON/XOFF control.
Dipswitch position #4 must be "ON" for DTR handshaking. For more
detailed information on serial port connections, refer to Appendix B.
