If you want Biab to SEND output chord data to Antares, you set it in the Output Chords (either pref/output or opt/output) from Biab. If you can't locate it, do a HELP search in Biab and type in output, that should locate it in Biab for you.

You can select which channel to send the data from Biab to Antares there and make sure they are connected via midi cable etc.
