5.2 Analog Output Programming Hints

This section described the function flow typical of single-point

analog output conversion. While performing the following

operation, the AO configuration function has to be called at the

beginning of your application:

a. Use PCI-6208A, PCI-6308A to perform current output

b. Use the analog output function that can convert a voltage

value to a binary value and then write it to device, the AO

configuration function has to be called at the beginning of your

application.

[Example Code Fragment]

card = Register_Card(PCI_6208A, card_number);

…

AO_6208A_Config(card, P6208_CURRENT_4_20MA);

AO_WriteChannel(card, chan, out_value);

…

Release_Card(card);
