Summary:

Inputs: BoardNum [U32] - The board number assigned when installed with InstaCal. Can

be 0 to 100.

ChipNum [U32] - Specifies which 9513 chip is to be initialized. FoutDivider [U32]

- F-Out divider (0-15)

FoutSource [U32] - Specifies source of the signal for F-Out signal.

Output:

ErrCode [U32] - Error code. See ErrMsg.VI

Arguments:

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

specified board must have a 9513 counter.

ChipNum Specifies which 9513 chip is to be initialized. For a CTR05 board, this should be

set to 1. For a CTR10 board, it should be either 1 or 2. For a CTR20, it should be 1

to 4.
