Collecting Inuvion Analog CD Signal

Issue

Customer would like to use an analog-to-digital box (A2D box, i.e. SatIN, etc) to collect the CD signal.

Environment

 Inuvion

Resolution

The A2D box  will have a cable to connect to the 12-pin green terminal block/connector strip on the back of the Inuvion. Two of the wires will be connected to the two analog pins and two of the wires will be connected to the relay pins. The relay pins are used to trigger the start of data analysis when the injection occurs. Please see Appendix B of the Inuvion Operator Manual.

An example:

In the Chromeleon Instrument Configuration:

NOTE: The Zero Flow Indicator box should be UNCHECKED.

A command will need to be entered into the Instrument method to close the relay in order to start the data collection when the injection occurs.
