AIO-16 Ports, DBX Linking, and Interconnects
AIO-16 Ports
With the introduction of an AIO-16 card into the ADAM frame layout, the number of possible ports available doubles from
136 ports (AIO-8) to 272 ports (AIO-16). This is because instead of eight (8) channels of audio per card, you now have 16
channels of audio per card.
Backwards Compatibilty
To be backwards compatible with the AIO-8 cards, the 16 channels had to be divided into two (2) separate groups of eight (8)
channels per card (a bottom group and a top group). For example, if you have an AIO-16 card in slot one of an ADAM frame,
the bottom group of eight (8) channels have ports 1-8 assigned to them, while the top group of eight (8) channels have ports
137-144 assigned to them, see Figure 12.
