DigiSerial Port General Info
Pro Tools MIX and d24 cards feature a
DigiSerial Port. Though this port is identi-
cal in appearance to the serial ports on your
CPU, it is designed to only be used for:
• the USD proprietary serial connection.
– or –
• a serial-to-9-pin cable in combination
with the MachineControl™ option for
Pro Tools. This should only be connected
to the DigiSerial Port when there is no
USD present in the system.
The DigiSerial Port should not be used for
connecting MIDI Interfaces or any other serial
device. Attempting to do so will adversely af-
fect Pro Tools performance.
