CAPsMAN, what are set if it not configured ?

Hello,
how the CAP device(s) properties are set if i not explicit configured in CAPsMAN.

For e.g. Wireless HT tx/rx chain or extension channel ?

Do i need different configurations for different hardware e.g. b/g and b/g/n devices if I want that they work in maximum possible connection speed or leave it blank

Thanks,
regards
Marcus
