Lock Design Overview
Why use User Codes?
With ordinary door locks, the need to make physical copies of metal keys and distributing them can be a huge organizational and
financial task -- and what will you do if someone causes a security breach by accidentally losing their key?
The answer lies in the advantage of "firmware". The firmware inside the lock can be programmed (and re-programmed again and
again) to suit your changing requirements. No more metal keys to distribute...instead, distribute User Codes -- and delete them
from the firmware when needed. A User Code is the firmware equivalent of a metal key--it is a series of numeric button-presses at
the lock keypad to allow (for example) passage through a door.
Preparing to Program User Codes
The PDLN4100 / PDLN4500 keypad contains 12 buttons, numbers 1 through 9 plus zero, a star button (:) and a special "AL"
button (;). You can use the keypad to program your lock, or you can use a computer program called DL-Windows that can be
configured to program your system wirelessly. This guide will show you how to program your lock using the keypad, without DL-
Windows. (For more information about DL-Windows, see User Guide OI382; for information about using DL-Windows within the
Networx wireless system, see OI383).
Before you can program your PDLN4100 / PDLN4500 lock using the keypad, you must first enter something called "Program
Mode".
What is Program Mode?
The software has only two "modes"--"Normal Mode" and "Program Mode". When you want to make changes to the lock program,
you enter "Program Mode". When you finish programming and wish to put the lock into use, you exit "Program Mode" to enter
"Normal Mode".
You can enter Program Mode using the keypad by pressing the Master Code of the lock that was set at the factory (then wait for
the green light and press ; until multiple beeps are heard). The Master Code is basically a secret 6-digit "passcode" that al-
lows you to enter Program Mode. But since all locks are identical and leave the factory with the same Master Code, this factory
Master Code is therefore not very secret--and should be changed to your own personal Master Code. This way, only YOU can
enter Program Mode and make changes to the lock programming.
Once the new Master Code is set , then you can continue with the Quick Start procedure and set the weekday, date and time.
After this, you can start entering User Codes for people to use. All changes to the lock are organized by their Function Number.
Want to change the date? Use Function Number 38. Want to add a User Code? Use Function Number 2. There are 99 Func-
tions in total, some that you will use often, and others that you may never need.
Notice that when you program your lock, programming tends to follow a
consistent 5-step pattern: (1) Enter Program Mode
(2) Press ; followed by the Function # (3) Press ; and enter data (4) Press : to end (5) Exit Program Mode to
put the lock into use.
Turn the page and learn about the special terminology used with your lock. Once that is clear, use the Quick Start proce-
dure on page 15 to help you get up and running.
