Since the Output lines are run off the optical couplers (PS2501-4) there must be an optical power source. In this example we have
bridged the optical power source with the internal power source of the Signal Generator by connecting lines 22 to 23 and 24 to 25 of
the DB25 Motor Signal connector.
Alternatively, we could have connected an external 5V power supply to pins 23 and 25 of the DB25 or the OPT GND and OPT +5V
pins of the output connector. Note that if an external power supply is used, the Load might get powered on if the Signal Generator is
turned off while the external 5V power supply is still on.
Also note that RP5 is a socketed 470 ohm pull-up resistor. This resistor value can be changed or removed depending on current
requirements for the input signal of the device you are switching. The resistor is an 8 pin 7 resistor package.
