Connecting the Control Inputs (Digital Inputs)

The calibrator is equipped with 12 digital control inputs that can be used to initiate various
user programmable calibration sequences and can be turned ON or OFF in the
Utilities>Diagnostics menu.
Access to these inputs is via two separate 10-pin connectors, labeled CONTROL IN, that
are located on the calibrator's communications and output panel.

There are two methods for energizing the control inputs (Figure 2-7): The internal +5V
available from the pin labeled "+" is the most convenient method. However, if full isolation
is required, an external 5 VDC power supply should be used.
