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.
