CHAPTER 3: SERIAL TO PARALLEL

INSTALLATION

When converting data from your serial port to a parallel

communication format, position #8 of the dipswitch must be "OFF".
The other seven positions should be set to match the data format of
your computer's serial port. Refer to Table 5.1 for dipswitch setting
specifications.

CONNECTING THE 232SPS2 TO YOUR PARALLEL PRINTER

The 232SPS2 has a DB-25 female connector on its parallel port.

Most parallel printers use a Centronics 36-pin connector. To insure
proper operation, you should use a cable that connects all 25 pins
from the DB-25 connector to the appropriate pins on a Centronics
36-pin connector. B&B's Model CPC is recommended. For detailed
information on which pins are connected on the parallel port, refer to
Appendix A.

CONNECTING THE 232SPS2 TO YOUR SERIAL PORT

The connections required between your 232SPS2 and your

serial port depend on the type of flow control used. The type of flow
control used depends on the software you are using. If you are
unsure which type of flow control your software uses or if you plan to
run different kinds of software, you should use a cable that connects
all 9 pins from connector to connector and set the handshaking
mode to be XON/XOFF control. In this mode both DTR handshaking
and XON/XOFF control are used for flow control. Dipswitch position
#4 should be "OFF" for XON/XOFF control. For more detailed
information on serial port connections, refer to Appendix B.
