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. 

 

 

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.
