5.1.2.1 Example: Using LEDs on the GPI Outputs

The GPI outputs on the MV-32/MV-64 are open collector drivers. There is a 5 Vdc pin to

provide the power needed to drive LEDs or relays.

The following schematic is an example of the wiring needed when an LED is to be driven by

each output. The numbers on the left are the GPI output numbers and pin-numbers for the

outputs on the 26 way female D-Type connector on the rear of the MV-32/MV-64.
