*About the available range,please refer to the manual of the using board
*In the initial state and if terminal is not connected, the initial setting value depends on the device
  Please refer to [Device-specific Setting List]

 

AiChannelNum

[-1] Can be set

Initial value: 1

In the case of analog input with buffer, specify the number of channels for sampling
The channels to be used are[Ch0 to Ch(AiChannelNum-1)]

 e.g.) When AiChannelNum is 3, the 3 channels (Ch0, Ch1, Ch2) are used in order

*In the case of analog input without buffer, this setting is ignored, so no need to set this terminal
*Some devices may not use [Ch0, Ch1, Ch2, ...], any channel can be used

Please refer to the advanced function [AioSetAiChannelSequence_i.vi]

 

AiInputMethod

[-1] Can be set

Initial value: -1(Not change)

Specify the connection type of analog input (Single-end/Differential)

0: Single-end input
1: Differential input

*About the available connection type, please refer to the manual of the using board
*In the initial state and if terminal is not connected, for the device which supports differential input only, the initial setting value is 1 (Differential input),

  For the other devices, the initial setting value is 0 (Single-end input)

 

Operate with initial value

There is an initial value for each input terminal setting.

For example, since the initial value of [AiChannelNum] that specifies the number of channels of analog continuous input is [1], there is no particular need to set [AiChannelNum] when sampling 1 channel.
