28The E-Plex 5000 and the E-Plex 3000 locks use a special 4-digit only Maintenance Code called the M-Unit UserCode. This code is used only to program and/or audit the lock using the M-Unit PDA as a maintenance function only– the code will not open the door.By default, the 4-digit M-Unit User Code is de-activated in the lock. The code cannot be activated and assigned fromthe software – it has be assigned a 4-digit code and then activated by the Master or any one of the Managers at thelock’s pushbuttons.For example, if 87654321 is the Master Code and the new M-Unit Code to be assigned is 7777, the following twocommands must be entered at the lock: #87654321#103#7777#7777## (to assign new M-Unit Code first), and then#87654321#303## (to activate it).If you ever need to de-activate it, the command is 403 (which replaces the 303 in the above example). An example ofthe M-Unit User Code usage at the lock is as follows: ##7777 (Note: there is an extra # at the beginning of thecode). The lock will enter the Communications Mode with the M-Unit handheld PDA, indicated by alternate greenand red flashing LEDs.Programming, Auditing Locks, and Downloading Lock ProfilesTransfer Files – PC to Maintenance UnitHow do I transfer files to the M-Unit?1.
