See Appendix C for the pin-out diagram
for the 25-pin D-Sub connectors.
Apogee Digital I/O
These cards have an optical digital
input connector for connecting eight
tracks to an ADAT or ADAT-optical
compatible MDM. They also have a 25-
pin D-Sub connector for connecting to a
Tascam MDM. Along with the 25-pin
connector is a Sync BNC connector for
providing sample rate clock information
to a Tascam MDM. See Appendix C for
the pin-out diagram for the Digital I/0
25-pin D-Sub connector.

ALT I/O

This slot is provided for an optional
card (AIO•8 or DIO•8) that can be
installed to provide eight additional
analog or digital inputs and outputs.
Any channel (1–48), Aux Send, or Bus
1–8 output can be assigned to the ALT I/O
outputs. Any digital ALT I/O input can be assign-
ed to Bus 1–8 or the L-R bus. See Appendix F
for more information on using I/O cards.
Sync
This slot is provided for an optional card
that can be installed to provide word clock or
blackburst in, SMPTE in, and ESAM II
machine control. (See Appendix F for Digital
I/O options.)
