Figure 5.9 – Signals of connector XC1 and connection of the digital inputs as active high
NOTE!
In order to use the digital inputs as active low, it is necessary to remove the jumper between XC1:
11 and 12 and change it to XC1: 12 and 13.
As default, the analog inputs and outputs come from the factory selected for the range 0 to +10V.
In order to change its operation range, you can change the position of switch S1, located on the upper left
corner of the CC900 electronic board.
