Driver Functions
agb220xa_timeOut_Q
This function returns the timeout value for driver I/O transactions in milliseconds.
Syntax ViStatus_VI_FUNC agb220xa_timeOut_Q(ViSession vi, ViPInt32 pTimeOut);
Parameters vi Instrument handle returned from agb220xa_init( ).
pTimeOut Minimum timeout period that the driver can be set to, in
milliseconds.
agb220xa_unusedPort
This function ground-enables the specified input ports of the specified card.
The parameter “unused_port” is an array of integers with each integer representing
one port. The last number of the “unused_port” should be “0” (numeric zero) to
identify the end of the array. The maximum number of ports that can be specified by
the array is agb220xa_UNUSEDPORT_MAX.
Syntax ViStatus _VI_FUNC agb220xa_unusedPort(ViSession vi, ViInt16 unused_cardno,
ViInt32_VI_FAR unused_port[ ] );
Parameters vi Instrument handle returned from agb220xa_init( ).
unused_cardno Card number. 1 (card 1), 2 (card 2), 3 (card 3), 4 (card 4), or 5
(all card) in the normal configuration mode, or 0 (all card in the
auto configuration mode). For the configuration mode, see
agb220xa_func.
unused_port[ ] Input ports to be ground enabled. 1 to 9 are available. Multiple
port numbers can be set.
The input ground port and a ground enabled input port cannot be assigned to the
same input port.
If the ground enabled input port and a couple port have been assigned to the same
input port, the ground mode and the couple mode cannot be used in parallel.
NOTE The ground enabled input ports are connected to the input ground port when the
ground mode is ON. So the ground enabled input connectors must be opened to
prevent the instrument from damage.
