Figure 46 Inputs
Note: Some of the input terminals and jumpers are not used for the Apollo I.
Each input has an LED that shows the current state of the input. Both the LED and input are labeled with the input
name. The inputs start counting from X0 and up to X8. If the LED is on, then the input is activated. Different
configurations can be selected for each input by using the jumpers near the bottom right of Apollo I. The jumpers start
counting from the left at X0 and increment up to X15. (X9-X15 are not used for the Apollo I.) Each jumper corresponds
to an input. For example, the jumper labeled X3 corresponds to the input on TB1 labeled X3 and the LED X3.
Figure 47 Input Jumpers
The figure below shows the schematic of an input where S is the input number. The jumper only shows the three pins
used for that input. Comparing it to Figure 47, pin 3 is on the top and the pin 1 is on the bottom.
