Board ID (0) Specifies the ADAC-LVi board ID number to be used in this acquisition.
The ID numbers are defined in the configuration file ADAC-LVi.con located in the
Windows main directory.
Device Type (2:DIN) Subsystem Type is a numeric value that specifies the board
subsystem to be allocated. The available options are:
2:DIN Digital Input
3:DOT Digital Output
The default Subsystem Type is 2:DIN
Element (0) Element is a numeric value that specifies the DIN or DOT port number to be
allocated. The 5600 ports range from DIN0 to DIN1 and DOT0 to DOT3.
Note that DIN1 is not available when DIN0 is configured for 16 bit Port Resolution and
DOT1 and DOT3 are not available when DOT0 or DOT2 is configured for 16 bit Port
Resolution respectively.
The default Element is 0.
Data Transfer Method (Software:0) Data Transfer Method is a numeric value that sets
the hardware transfer method. Only 5600 series cards with DIN0 Interrupt capability can
be configured for Interrupt operation. For all other DIN and DOT ports Data Transfer
Method must be set to SOFTWARE, only single read or write operations are available
and the 5600 PORT STRUCT cluster is not used. The available options are:
0:SOFTWARE Data is transferred via a single read or write operation. Supported by all
5600 ports.
1:DMA Not available on the 5600 series.
2:IRQ Data is transferred via ISR, supported by DIN0 only.
The default Data Transfer Method is 0:SOFTWARE.
5600 PORT STRUCT
Port Resolution Port Resolution is a numeric value that represents the desired
number of DIO port bits, either 8 or 16. The DIO ports DIN0 can be either 8 or
16 bit ports and DIN1can only be an 8 bit port. When DIN0 is set for 16 bit
resolution DIN1 is not available. The DIO ports DOT0 and DOT2 can be either
8 or 16 bit ports and DOT1 and DOT3 can only be an 8 bit port. When DOT0 or
DOT2 is set for 16 bit resolution DOT1 or DOT 3 is not available respectively.
