NI-6343 the buffer of AO and DO

      I have Used the CVI program to creat 4 AO Channels which in the  NI-6343 board ,so that the board can output datas at the same time, now I want to generate the Digital Data line in the DO Channels which can start with the AO signals at the same time too.

      So is the buffer of the AO and DO are in the same area or they have their own areas that won't affect each other ?
