@ Description
Set the clock mode and start mode for the PCI-7300A DI operation.
@ Syntax
Visual C/C++ (Windows 95)
int W_7300_DI_Mode (int card_number, int clk_mode, int
start_mode)
Visual Basic (Windows 95)
W_7300_DI_Mode (ByVal card_number As Long, ByVal clk_mode As Long,
ByVal start_mode As Long) As Long
C/C++ (DOS)

start_mode)
@ Argument
card_number: The card number of the PCI-7300A card.
clk_mode: DI_CLK_TIMER: use timer0 output as input clock
DI_CLK_20M: use 20MHz clock as input clock
DI_CLK_10M: use 10MHz clock as input clock
DI_CLK_REQ: use external clock (DI_REQ) as input
clock
DI_CLK_REQACK: REQ/ACK handshaking mode
start_mode: DI_WAIT_TRIG: delay input sampling until DITRIG
is active
DI_NO_WAIT: start input sampling immediately
@ Return Code
NoError
PCICardNumErr
PCICardNotInit
InvalidDIOMode
