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-pi

CHAPTER 4: POWER CONNECTIONS The unit may be port-powered using DTR and RTS on the serial port. If the 232SPS2 cannot be powered using the handshake lines, it may be powered externally using +7 to +18 volts DC at 2 milliamps. If you are using an external supply, simply plug a 2.5 mm plug from an appropriate DC source into the power jack on the side of the 232SPS2 module. Power supplies are available through B&B. (Model 232PS is recommended.) 232SPS2-3903 Manual Chapter 4: Power Connec
