Controls: File Menu >> File Info >> Chans

This shows the channels used by the current open data file or the most-recently loaded Arb or Play file. Daqarta can open files with up to 4 channels: Left and Right Input plus Left and Right Output. These would simply be listed as 'LI, RI, LO, RO'.

Only Daqarta's own .DQA format can keep track of individual channel assignments. If you open a .WAV or .DAT data file, Daqarta will assume that a mono file is Left Input, and a stereo file is Left and Right Inputs.

If you open a mono or stereo file for Arb or Play use with the Daqarta Generator, the channels will be shown here as Left and Right Outputs.

When recording inputs or generating outputs, Daqarta allows you to control or account for the polarity of each channel using the Full-Scale Range and External Gain dialogs. If you save a file using the .DQA format, this polarity information is preserved and used when you later open the file. If a channel is to be shown inverted relative to the actual stored data polarity, its channel abbreviation is here preceded with a '-' sign, as in '-LI'.

Standard .WAV files have no place to store polarity information, so they will never be shown inverted here.

For .DAT files, Daqarta allows you to specify polarity via the Invert option in the .DAT File Format Dialog. Unlike .DQA files, however, any inversion is always applied the same to all channels, and shown as such here.
