4. Password Security
4.1. Overview
DCM2 controllers use 4 levels of password for controller access and to stamp the activity log:
Public, Operator, Configuration, and Administrator
Refer to Section 4.2 for default user IDs and passwords.
Passwords are defaulted OFF for keypad users and ON for Browser users.
Passwords cannot be turned OFF for Browser users.
There are 7 user assignable passwords which are distributed between Operators & those allowed to Configure.
Passwords are a maximum of 9 letters and numbers and are case sensitive. The controller blocks the use of
HTML delimiter characters by limiting password content to letters and numbers only.
The controller blocks duplicate passwords.
