C9513Init.VI
Initializes all of the chip level features of a 9513 counter chip.
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.
Compare1 [TF] - ENABLED or DISABLED
Compare2 [TF]- ENABLED or DISABLED
TimeOfDay [U32] - DISABLED (0) or 1-3
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.
Refer to board-specific information contained in the Universal Library User's
Guide (available on our web site at www.mccdaq.com/PDFmanuals/sm-ul-user-
guide.pdf ).
