3.5.3.3 “resetpw” Command
This command is used to remove password protection from the MPI.
3.5.3.4 “maint ascii pw” Command
Once a password has been set, pressing the Enter key three times no longer removes the
maintenance lockout. It will instead display a message, “MAINT LOCKED OUT – PW
PROTECTION”. This will continue to display until the command “maint ascii pw <password>” is
entered correctly into the terminal to gain access to the MPI.
3.5.3.5 Resetting Forgotten Password
In the case where a password is lost or unknown, the following reset procedure must be
performed which requires access to the physical unit.
1. Remove power from the FDL-978.
2. Ground pins J1-12 (Anonymous Mode), J1-15 (Traffic Test), J1-27 (Air/Gnd).

3. Apply power to the FDL-978, and turn on by grounding J1-32 (Remote On).

The Installation Adapter (P/N 87988-00) can also be used to perform the above
operation.
This will remove the password protection from the MPI and allow normal access.
