Industrial Data Systems IDS DT220 - Manual (Page 4)

Meter Simulator Feature: The Weight Meter Simulator is used when no internal
Analog card is installed and the unit is to be used as a data terminal connected to
a weight meter. This feature allows you to select a meter type and simulate status
and weight conditions. The Setpoint function allows incrementing and
decrementing weight up or down to a pre-set value.
Test your programs with the simulator if no analog card is installed no need
for a meter. NOTE: Use port 1 for the scale input port & port 2 for EZLink220
