Connect the Inputs
Step 4: Connect the Inputs
All 8 inputs on the I/O Expansion Board are fully programmable so any door contact,
alarm signal, REX etc. can be connected to any of the 8 inputs. The function of each
input is programmed via the Controlsoft Lite or Controlsoft Pro software (please refer
to relevant manuals)
Inputs are connected to terminal blocks J10 (inputs 0 to 3) and J12 (inputs 4 to 7).
Each input has an indicator LED just above the input terminal. This LED illuminates
when the input is shorted.
Each group of inputs (0-3 and 4-7) can operate in one of three modes:
• External
Mode
•
Internal Mode (Common Positive)
•
Internal Mode (Common Negative).
External Mode is useful when the trigger device switches a voltage source to the I/O
Expansion Board. To select External Mode, use a single jumper link on J1
(confi gures inputs 0 to 3) or J2 (confi gures inputs 4 to 7) across the
centre pins as shown opposite:
Example: to wire a trigger device over 25m away to Input 7 with External
Mode:
