Driver Functions
The parameter “closechan_list” is an array of integers with each integer representing
one channel. The last number of the “closechan_list” should be “0” (numeric zero)
to identify the end of the list. The maximum number of channels that can be
specified by the list is 100.
The “close_status” parameter is an array of integers containing the return values of
the query. The “close_status” array returned will correspond one to one with
“closechan_list” parameter.
Syntax ViStatus _VI_FUNC agb220xa_closeList_Q(ViSession vi,
ViInt32_VI_FAR closechan_list[ ], ViInt32_VI_FAR close_status[ ] );
Parameters vi Instrument handle returned from agb220xa_init( ).
closechan_list[ ] Channel numbers to know the close status. 5 digits integer.
ABCDE. where A: card number, BC: input port number, DE:
output port number. Top zero(s) can be ignored. For example, if
A=0, BC=01, and DE=01, channel number should be 101
instead of 00101.
close_status[ ] Status of the channels given in the closechan_list.
0 (opened) or 1 (closed).
agb220xa_cmd
This function passes the cmd_str string to the instrument. Must be a NULL
terminated C string.
Syntax ViStatus _VI_FUNC agb220xa_cmd(ViSession vi, ViString cmd_str);
Parameters vi Instrument handle returned from agb220xa_init( ).
cmd_str Instrument command (cannot exceed 256 bytes in length).
agb220xa_cmdData_Q
This function passes the cmd_str string to the instrument. This entry point will wait
for a response which may be any data. You specify the cmd_str and size parameters,
and get result[ ].
Syntax ViStatus _VI_FUNC agb220xa_cmdData_Q(ViSession vi, ViString cmd_str,
ViInt32 size, ViChar_VI_FAR result[ ] );
Parameters vi Instrument handle returned from agb220xa_init( ).
