13.1.3 Low Voltage Sourcing Inputs (PNP)

For 2.5-10V inputs, connect the positive voltage to the C0+ terminal and ground to C0-. Completely remove the
jumper corresponding to the input and connect XNL (where N represents the input number) to GND. Then connect
the signal to the corresponding input.
Assuming that the jumper for X5 has been removed, the example below shows how to wire in a 5V toggle switch.

13.1.4 Sinking Inputs (NPN)

For most NPN proxies place the jumper on the top two pins. Then connect the signal into the corresponding input.
See the example below.

If the proxy has an internal pull-up resistor, depending on its size, it could require the jumper to be completely
removed. Use a 3.9k ohm resistor and connect it between XSL and C0+.
Below is an example of a 24V NPN proxy with an internal pull-up resistor. The jumper on the Apollo III must be
completely removed for this to work.
