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.
