returns the current configuration information.

Inputs: InfoType [I32] - The class of configuration information that you want to retrieve.

BoardNum [I32] - The board number assigned when installed with InstaCal. Can be

0 to 100.

DevNum [I32] - Specifies the board device.

ConfigItem [I32] - Specifies the configuration item.

Outputs:

ConfigVal [I32] - Current configuration value.

ErrCode [I32] - Error code. See ErrMsg.VI

BOARDINFO - General information about a board.

DIGITALINFO - Information about a digital device.

COUNTERINFO - Information about a counter device.

EXPANSIONINFO - Information about an expansion device.

MISCINFO - One of the miscellaneous options for the board.

BoardNum The board number associated with a board when it was installed with InstaCal.

DevNum Selects a particular device. If InfoType=DIGITALINFO then DevNum specifies which
