PASSWORDS

DDEC VI is capable of providing password protection for groups of parameters or a fleet
password for all parameters.
5.21.1 OPERATION
A Password of zero is used to deactivate the protection. The lockout passwords may be up to 4
ASCII characters. Each level can have its own unique password.
Passwords can be activated with DDDL 7.0, VEPS or DRS. Once activated the parameters may
not be changed until the correct password is reentered. The CPC is automatically locked at the
next ignition cycle.
Groups selected for additional password protection are listed in Table 5-69.
