SigmaDAQ Version Released! Now includes support for RS-232 Devices.


A new version of SigmaDAQ is now available on the LabVIEW Tools Network which includes data acquisition support for meters, gauges, controllers, and devices over an ASCII RS-232 interface.  See release notes here.  A new configuration utility is available which allows for the ability to select acquisition settings as well as common serial settings.

For example a typical pressure meter may return the current pressure in mmHg is response to the command “CP\n”.  The response to the command may look like “CP123.25mmHg\n” where the current pressure is 123.25mmHg.  To configure communication for this device, simply set “CP” as the Data Request Command, set Write and Read Termination Characters to 0x0A (newline character), and set Read Data Offset to 2 bytes (to index the data past the “CP” in the response).
