In NI 9203 Getting Started Guide, I have found, that on the left part of the connection diagram, there is a different connection option marked with dashed line. Why and when should I use each of these options?


Connection option depends on the type of the sensor.
If sensor is:
  • active - you need to connect it as the continuous line shows,
  • passive - dashed line indicates the needed connection.
Reason for these type of connection is that the active sensors needs a supply voltage, or a set level of energy to perform a task and passive sensors do not control electricity directly and do not require external power sources to accomplish control of an electrical signal.
