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
