PAD-4 Operation, Installation, and Maintenance Manual
5.1.1 Selecting the Input/Output Configuration
Figure 5-1 shows the position of each switch on the DIP switch for various input and output configura-
tions. Refer also to Figure 5-2 for the terminal block designated on the PAD-4 or PAD-4-CLSA board.
The position of switch 4 through 10 does not affect the relationship of inputs to outputs.
Note: Changing settings for DIP switches 1-3 may affect the settings for jumpers J4-J8.
