1. Introduction
This document describes how to configure and use Kaba’s E-Plex 5900 stand-alone battery operated lock that
reads ISO 14443A compliant DESFire smart cards as user credentials enrolled in a “Card-Connected Access
Control System”. This “Corestreet Enabled” E-Plex 5900 lock functions as an integral part of a Card Connected
Access Control System granting access to users with valid credentials who were enrolled in a Card-Connected on-
line headend system.
For quick start, jump straight to the ‘Quick lock configuration’ and ‘the Quick lock update’ sections of the manual,
starting from page 19.
1.1 Scope
The document covers the initial lock setup, operation, keypad commands and usage including the use of the E-
Plex 5900 handheld Maintenance Unit (M-Unit) PDA which is also used to setup the lock.
1.2 Intended audience
This user guide was generated for use by internal Kaba engineering teams. For now this document will be used as
the E-Plex 5900 Card Connect Lock User Guide by the beta test customers during the beta test period as
reference.

2. Lock types
The E-Plex 5900 currently supports one of the two lock types with lock functions as:
Cylindical lock without thumbturn, supporting an “Entry” lock function.
Cylindrical or mortise lock with privacy thumbturn (with deadbolt for mortise), supporting a “Privacy” lock
function [** this model is for future offering only; currently not available “”]
The type of lock is configured through this access control system’s “Admin card” programmed by the on-line
headend system. Currently the E-Plex supports the DESFire card as user credential which is an ISO 14443A
compatible read/write RF card. It is important that the lock type be correctly setup at the outset because detection
of ‘door forced’ and ‘door open from inside’ conditions relies on it. The factory default of an E-PLex 5900 lock
function is “Entry” with the lock type being a cylindrical lock without a privacy thumbturn.
3. Operation modes
The lock operates in one of the following modes:
Factory
Construction
Access
Bootloader
3.1 Factory mode
Out of the box, the lock is in factory mode with a lock function as “Entry” and with an 8-digit PIN to open the lock as
12345678. This mode provides the operator with a known initial state. The operator can:
Unlock the lock by entering the default PIN on the keypad: 12345678
Change the default PIN
Validate the lock electronics hardware components
In this mode, only the factory default PIN of 12345678 will open the lock but not users’ DESFire cards.
3.2 Construction mode
Once the default PIN is changed, the lock enters construction mode. This mode is used until the lock can be
configured using an admin card (which requires the enrollment system to be in place at the headend access
control system). The operator can:
Unlock the lock by entering the new construction mode PIN on the keypad
Communicate with a maintenance unit (M-Unit) which is typically a Windows Mobile 5.0 compatible
handheld PDA, using the default communications key (16 zeros) to access the following functionalities:
oSet the date/time, daylight saving time info and time zone
oUpdate the bootloader
oUpdate the firmware
Use one of the following lock keypad commands
oChange PIN

7/37
7
oSet date and time
oSet passage mode
oConfigure the lock using an admin card
oSet lockout
oRun diagnostics and display various states of the lock
oEnter communication mode
Reset the lock to factory mode
In the construction mode user cards will not be recognized by the lock.
3.3 Access mode
Once the lock is configured using the admin card, the lock enters the “card connect” access mode and the
construction PIN will not work anymore. In this mode the user can:
Unlock the lock by presenting a valid credential (an ISO 14443A compliant DESFire card or optionally
entering a user PIN followed by the card).
Communicate with the maintenance unit using the configured communication key to access the following
functionalities (requires maintenance unit privilege):
oSet the date/time, daylight saving time info and time zone
oUpdate the bootloader
oUpdate the firmware
Use one of the following keypad commands
oSet date and time (requires keypad programming privilege)
oSet passage mode (requires passage mode privilege)
oConfigure the lock using an admin card (requires admin card privilege)
oSet lockout (requires lockout privilege)
oPerform diagnostics and display lock’s various states (requires lock keypad programming
privilege)
oEnter communication mode (requires maintenance unit privilege)
Reset the lock to factory mode
In this mode cards are required to unlock the lock.
3.4 Bootloader mode
The bootloader mode is a transition mode when updating the lock firmware. Before starting a lock firmware
update, the lock automatically switches to this mode. It remains active until a new firmware is fully received by the
lock. Should the firmware upload be interrupted (communication failure), the lock remains in bootloader mode.
Whenever a key is pressed, the green and red leds will blink sequentially while waiting for a maintenance unit
connection. If no connection is established within 15 seconds, the leds are turned off and the lock waits for
another key press.

4. User access
The following table lists the different user access methods depending on lock mode. On granted access, the
green led will turn on with a high pitch sound. When access is denied, the red led is turned on with low pitch
sound. Take note that a pin can be cleared by pressing the *key.
Mode Method
Factory Press the following key sequence:
12345678
Construction Press the following key sequence:
XXXXXXXX
Where:
XXXXXXXX is the 8 digit construction pin (see ‘Quick lock configuration’ section
or ‘Keypad programming’ section
Access In “card connect” access mode, access requires a card to be presented (< half an inch)
in front of the lock housing where the black antenna unit is installed. The lock can be
configured so that the credential is either pin followed by card, or card only mode
(configuration from the admin card, programmed by the headend system).
If the lock is configured in pin and card mode:
1. Type in pin
2. Present card
If the lock is configured in card only mode:
1. Present card
Note that in card only access, the lock allows the user to enter his pin first also as in pin
and card access mode.
4.1 Access unlock duration
When a user accesses a lock, the lock unlocks for a period of time defined by:
Standard unlock duration if user does not have the ADA privilege (Disabilities Act)
Extended unlock duration if user has ADA privilege (Disabilities Act)
These unlock durations are configured using the admin card which is programmed by the headend system.
Note that the ADA privilege is set on the user card by the headend system.
5. Passage mode
Passage mode is used to keep a lock unlocked for a given period of time and no credential is needed to access.
The lock is set in passage mode when a user with ‘passage mode’ privilege enters the ‘activate passage mode’
keypad command. The lock remains unlocked until:
The configured passage mode duration expires (from admin card),
Temporary duration, specified in same keypad programming session, expires.

9/37
9
The passage mode activation period (start & end times) is set when the passage mode is first activated. Any
deactivation/reactivation of the passage mode during the activation period does not reset the expiration (end time).
However, if a new temporary duration is set in the same keypad programming session as a reactivate passage
mode command, the expiration is modified.
Eg. if passage mode is activated at 1:00 and the configured duration is 5 hours, the lock will relock at 6:00 even if
passage mode was deactivated and reactivated several times in the 1:00-6:00 period. However, during the 1:00-
6:00 period, if a new temporary duration is set followed by a reactivation command (in the same keypad
programming session), a new expiration is set. E.g. at 2:00, set temporary duration to 1 hour and in the same
keypad programming session reactivate the passage mode, the lock will relock at 3:00 instead of 6:00.
This feature can also be used to temporarily extend the passage mode period.
6. Privacy (** for future offering only **)
Privacy enables any user to prevent other users from unlocking a lock (unless they have the ‘privacy override’
privilege). Turning the thumbturn in the horizontal position activates privacy and locks the lock. Privacy activation
deactivates passage mode and also locks the lock.
The privacy unlock option must be marked as ‘enabled’ in the admin card programmed by the headend, otherwise
the lock does not respond to the thumbturn.
7. Lockout mode
Lockout mode enables a privileged user to lock the lock and prevent any other cardholder to unlock it (unless they
have the privilege to deactivate the lockout).
Lockout is activated:
Using a keypad command (requires cardholder ‘lockout privilege’)
Using the mechanical key override
Lockout is deactivated:
Using a keypad command (requires cardholder ‘lockout privilege’)
By inserting and turning the mechanical key and unlock.
8. Tamper detection
Tamper detection helps preventing users from guessing access pins of other cardholders. Tamper detection is
controlled using two parameters configured by the headend on the admin card:
Tamper count: allowed number of consecutive incorrect pin or card input
Tamper shutdown time: time during which attempts to unlock the lock are denied.
Tamper shutdown is activated:
By entering, consecutively, incorrect pin or card more than the configured ‘tamper count’.
Tamper shutdown is deactivated:
By inserting and turning the mechanical key and unlock.

10/37

9. Remote Unlock option (*must be installed to operate*)
If installed, the remote unlock option enables users to unlock the lock with a normally open, momentary on/off
switch. This switch is connected to the remote unlock connector inside the lock by a 24 AWG gage twisted pair
wire up to about 100 feet in length The remote unlock option must be marked as ‘enabled’ in the admin card
programmed by the headend system, otherwise the lock will not respond to the remote unlock switch.
When enabled, remote unlock can be used to unlock the door during:
Tamper shutdown
However it will not unlock the lock:
During lockout
[When privacy is enabled for privacy locks; ** future**]
10. Door Ajar Sensing option (*must be installed to operate*)
If installed, the door ajar sensing option senses the door opened (and then door closed) status when opened from
outside (ingress); and also the door opened status when opened from inside (egress). In either case the door ajar
events are audited in the lock’s memory and passed on to the headend system via the admin card as logged
entries. In factory mode only, the lock will also visually indicate occurrences of these events: an alternate red and
green flash sequence for an egress, a double green led flash when door is opened from outside and a double red
led flash when it is closed.
11. Resetting the lock to factory defaults
The lock can be reset to factory defaults at any time by following this procedure. Warning: When a hard reset like
this is performed, all newly programmed lock configuration parameters, user access privilege policies etc will be
erased from the lock memory and the lock will default to the factory default lock parameters and the factory default
PIN of 12345678. However, the current date & time will not be altered.
1) Insert and turn mechanical override key to retract latch and hold,
2) Press key ‘#’ and release key override within 5 seconds
3) While red and green led flash alternately, press sequence ‘12345678#’ (if successful, green led
flashes twice with high pitch beep) and the lock is reset to factory defaults.
Note that audit logs are not erased by this procedure.
12. Mechanical key override
The key override is used to:
Mechanically unlock the lock (insert and turn the key to retract the latch)
Reset the lock to factory defaults (see ‘Resetting the lock to factory defaults’ section)
Reset tamper shutdown (see ‘Tamper shutdown’ section)
Deactivate lockout (see ‘lockout mode’ section)

11/37

13. Lock keypad commands
Using keypad commands, a user can do maintenance operations on the lock.
The following table lists the modes and available commands.
Mode Commands
Factory Only one command is available in factory mode:
Set construction mode pin
Construction All commands, without any restriction, are available in factory mode:
Set construction pin (in factory or construction mode)

13.1 Entering keypad programming mode
Keypad programming mode is entered differently, depending on the current operation mode. Start the keypad
programming mode by pressing the # key followed by PIN #, if the lock is in construction mode, for example. The

12/37
12
commands are then entered by pressing 3 numbers pertaining to the command code followed by a #. Then,
depending on the command, one or more parameters are entered, separated by # keys. The # key acts as a
confirmation (like an “Enter” key on a PC keyboard). Finally, press the # key again to exit the keypad programming
mode:
# Command# parameters# parameters# … #
Example of a complete command sequence: To set date (001 command code) & time (002 command code),
assuming 87654321 is the construction PIN, and the date and time you are setting is June, 19th 2007, 1:30PM):
# 87654321# 001# 061907# 061907# 002# 1330# 1330# #
Maximum 5 seconds are allowed between key presses and a maximum of 15 seconds between command
sections. Note that the * key can be used to clear the current parameter or command. The following table lists the
different methods of entering in keypad programming mode:
Mode Procedure
Factory Enter the factory default pin by pressing the keys in the following sequence:
#12345678#
Construction Press the keys in the following sequence where the PIN must be 8 digits in length:
#PIN#
Where PIN is the construction pin which must be different from the factory pin.
Access If the lock was configured for pin and card, enter the following sequence:
1. #PIN#
2. Present card
Where PIN is the cardholder pin (anywhere from xx to 20 digits?)
If the lock was configured for card only, enter the following sequence:
1. #Present card
13.2 Exiting keypad programming mode
To exit keypad programming after a command was entered, do one of the following:
Leave the lock idle for 5 seconds. Red led will turn on with low pitch tone, or
Press the # key. Green led will turn on, followed with 2 high pitch beeps.
13.3 Commands
The following table list the lock keypad commands recognized by the lock. Remember that privileges are required
to access commands once the lock is configured. If the cardholder does not have the required privilege to access
a command, the red led is turned on. Once a command is entered successfully, the green led will turn on with high
pitch sound (same for its parameters). If the command is executed successfully, the green led is turned on with 2
high pitch beeps.

14. Maintenance unit (M-Unit PDA)
The E-Plex 5900 M-Unit is a Windows Mobile 5.0 compatible handheld PDA running Kaba’s E-5900 M-Unit
software. The M-Unit is utilized for occasional interaction with the locks on-site and day to day operation of the lock
is possible without the M-Unit. Please refer to the “Appendix” section at the end of this document on how to install
the “E-Plex 5900 M-Unit” software application on your Windows Mobile PDA.
The E-Plex 5900 M-Unit can be used to perform the following functions:
Setting Date/Time Parameters
Setting Communications Key
Updating Lock Firmware
Performing Lock Diagnostics
Important: The communication between the lock and the PDA is via the IrDA (infra-red) interface. Hold and point
the M-Unit to the lock so that the small dark red infra-red glass windows of both devices face each other straight at
a distance of between 4 and 8 inches for successful communication – see the picture on the right below.
These functions are all available from the main M-Unit program menu, displayed when the application is run:

16/37
16
14.1 Setting Date & Time
When the Set Time function is invoked, the following page is displayed:
This screen dialog is used to configure and send to the lock all of the following data:
•Whether or not DST is to be used in this lock
•Start time of DST
•End Time of DST
•DST Offset (how far we adjust the clocks on a DST shift)
•Local Time Zone. This is the difference between local standard time and UTC, and is not adjusted for
DST.(Example: set “-5” for Eastern Standard Time)
When this function is activated, the application will display the last saved settings, if they can be found. If no saved
settings are available (the data file was deleted or the settings were never saved), default settings will be
displayed. Note that if DST is unchecked, the fields that pertain to DST will be disabled. The last saved data will be
displayed, but will not be sent to the lock. Click on “Send” button to send the current date & time to the lock.

17/37
17
14.2 Setting the Communication Key
The Communication Key is used as a customer unique security key comprising a sequence of hex numbers. This
key is transferred in the lock (through the Admin card), and will be sent by the M-Unit to the lock at the beginning
of each communication session. This ensures that only a person knowing the key value in the lock can interact
with the lock using the M-Unit. Important: The key is not generated by the M-Unit application itself but by the
headend system and the M-Unit operator must enter these numbers at the initial M-Unit setup. The M-Unit will
simply pass these pre-set values to the lock in order to enter communication with the lock.
When the Communication Key selection is made, the M-Unit screen will display the last saved set of key values:
If no key values have been saved, the boxes will be filled with all zeros. Use the “Clear” button to empty all fields
and begin typing in new required values. If the boxes are initially empty, the focus will automatically jump to the
next box as each one is filled, thus facilitating rapid entry of new keys.

18/37
18
14.3 Updating the Lock Firmware
There exist two separate files that the M-Unit can upload to the lock. One is the “bootloader” and the other is the
lock “firmware” itself. The bootloader is a separate small program that is invoked to replace the E-Plex 5900
firmware file in the lock. The normal procedure is to first replace the bootloader, and then the firmware file.
However, if the operator knows that there is no change to the bootloader, it is perfectly acceptable to simply
update the firmware file using the existing bootloader.
Important: In order to perform a firmware upload the lock must be placed under control of the bootloader. This
means that after starting communication, the lock will beep and shut down for a few seconds. You must not move
the M-Unit away from the lock during this period. After approximately two seconds the M-Unit will begin
communicating again with the lock, and will proceed to upload the new firmware file. On completion of this transfer,
the lock will reboot and activate the new firmware.

19/37
19
14.4 Performing Diagnostics
The M-Unit can query the lock for a collection of useful status info from the lock including a validity check on the
lock electronics, green and red leds and the buzzer. Click on “Get” to display the results:
The Diagnostics will repeat in a continuous loop until it is stopped either by removing the M-Unit PDA from the lock
vicinity or by selecting the “Stop” button. This loop function is useful for verifying all the keys on the lock keypad
etc. [Note: The current beta version of the M-Unit software will only take a “snapshot” of the diagnostics status
once and will display it as shown above. There is no “Stop” button and no continuous loop diagnostics at this time].
15. Audit Logs
The E-Plex 5900 keeps a log entry for every transaction or event encountered in its memory. The audit log entries
are stored in a circular list, where newer ones overwrite older ones. Events like any DESFire card user access,
passage mode on/off status etc are logged and transferred to the headend system automatically. Note that audit
og entries in the lock are never erased from the lock; the only time an audited event gets erased is when it is
overwritten by a more recent event when the lock audit buffer is full. The lock can store up to 30,000 audits. For
the beta version, only the last 10 audit events can be stored on a user’s card to be read on the headend system
later; however, in the final version all 30,000 audited events can be transferred to the M-Unit to be processed at
the headend system.

16. Quick lock configuration
The following tables describe the sequence of commands required to configure the lock from factory,
construction and access mode. Note that:
oTypically a timeout of 5 seconds applies to key presses and card detection. After this delay, the
current operation is cancelled (red led turns on along with low pitch sound).
oKeypad commands are always followed by a ‘#’ key.
16.1 In Factory or Construction mode
Step Sub Description/Operation Notes
1 Reset the lock to factory mode
1 Insert and turn mechanical key in key
