Initial Setup
› On a new unit, all fingerprint indexes are unused.
› When a new unit is powered up, it will immediately go into the Initial Setup
menu. The menu consists of a number of options that can be selected or
turned on / off, and requires numeric alues to be entered using the keypad.
The initial setup of each db Nexus unit is ery simple and should only take a couple
of minutes.
When the unit is powered-up, you should see the following on the Head Unit's LCD:
LCD CONTRAST
(0- ):[0] #=DONE
› Using the keypad on the Head Unit enter a alue 0 thru to set your
preferred contrast for the LCD display. You will see the contrast change as
each alue is selected. If the chosen contrast is not correct, try a different
alue until you ha e the desired contrast.
› Once you ha e the desired contrast, press the # key.
The next screen on the Head Unit LCD will be:
<Blank Line>
ENTER PASSWORD
› Enter a 16-digit numeric password. This is used for the code hopping
encryption that operates between the Head Unit and Control Unit and also
between the Control Unit and PC software.
Note: This same password must also be entered into the Management
Software, so please make a record of the password before entering it.
› Following the 16th digit being entered, the Head Unit will display the entered
password on the top line of the LCD and display [#]=DONE on the bottom
line. The cursor will mo e to the # character to allow you to re iew the
password. If you are certain that the password has been entered correctly
press the # key. If you want to change the password, use the * key as a
back-space to delete the password entered.
Note: This alue cannot be re-entered. This is a one-time only process.
The next stage is to optionally enroll 2 managers onto the unit for testing purposes.
The following messages will be displayed on the Head Unit LCD:
ENROLL MANAGERS?
YES=1 NO=0
It is highly recommended that you enroll the 2 managers at the Head Unit for testing
purposes. If you choose not to enroll managers ia the Head Unit at this point, the
unit will need to be networked and users enrolled onto the unit ia the DAS
Management Software.
