agb220xa_groundChanList_Q

This function will query the instrument for the status, ground enabled or disabled, for the channels given in the list.

The parameter “gndchan_list” is an array of integers with each integer representing one channel. The last number of the “gndchan_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 “gnd_status” parameter is an array of integers containing the return values of the query. The “gnd_status” array returned will correspond one to one with “gndchan_list” parameter.

Syntax	ViStatus _VI_FUNC agb220xa_groundChanList_Q(ViSession vi,
	ViInt16 gnd_disen, ViInt32_VI_FAR gndchan_list[ ],
	ViInt32_VI_FAR gnd_status[ ] );
Parameters	vi	Instrument handle returned from agb220xa_init( ).
	gnd_disen	Query type.
		0 : checks if the port is the ground enabled.
		1 : checks if the port is the ground disabled.
	gndchan_list[ ]	Channel numbers to check the 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.
	gnd_status[ ]	Status of the channels given in the gndchan_list. Returned value

depends on the setting of gnd_disen as shown below:

when gnd_disen=0, 0 means ground disabled, 1 means enabled. when gnd_disen=1, 0 means ground enabled, 1 means disabled.
