5.7_9112_DA

uDescription

This function is used to write data to D/A converters. There are two Digital-to-Analog conversion channels on the PCI-9112. The resolution of each channel is 12-bit, i.e. the range is from 0 to 4095.

C/C++ ( DOS)

int _9112_DA (int card_number, int da_ch_no, unsigned int data )

uArgument

card_number : the card number of PCI-9112

da_ch_no : D/A channel number, DA_CH_1 or DA_CH_2.

data : D/A converted value, if the value is greater than 4095, the higher bits are negligent.

uReturn Code

ERR_NoError, ERR_BoardNoInit

ERR_InvalidDAChannel
