USING THE LCD KEYPAD 
All steps required for programming are the same as the aforementioned LED keypad.  The LCD keypad display will 
prompt you for the data required.  While in the programming mode, and not in a location, the number in parenthesis 
is the location you were previously changing.  For example, if the display reads "Enter location, then #   (5)", it is 
reminding you that location 5 was the last location you programmed.  In feature selection data, the numbers of the 
enabled features will be displayed. The features not enabled will display a hyphen (-). 
PROGRAMMING DATA TYPES 
Numerical Data 
Numerical data can take on values from 0-255 or 0-15 depending on the segment size. 
 
Feature Selection  
Feature selection data is used to turn features on or off.  
 
 
USER CARDS 
Adding and de-activating users is done through a combination of entering information at the keypad and scanning 
cards. Before a card can be entered, one reader on the system must be programmed with User Card Programming 
enabled (Location 242, Segment 1, Option 1, page 11).  
 
   It is recommended that only one reader on the system be enabled to modify user cards and 
that this reader be located near a keypad. This reader will transfer information to all other 
readers in the system once programming is finished.  
 
Once a reader is enabled to modify users, it must be placed into one of the following five modes: 
1)  Add One User 
2)  Add Multiple Users w/ Auto-Increment 
3)  Activate One User 
4)  De-Activate One User 
5)  Delete/Reset One User.  
Modifying users on a card reader is similar to modifying user codes at a keypad. 
 MUST BE A MASTER USER IN ORDER TO MODIFY USER CARD INFORMATION.

1)  Add One User 
2)  Add Multiple Users (w/ Auto-Increment) 
3)  Activate Single User 
4)  De-activate One User 
5)  Delete / Reset One User 
IMPORTANT NOTE 
Adding or de-activating user cards from a reader will cause the code for User Number 2 to become invalid. Therefore, it 
will need to be re-entered after all user cards are programmed into the readers.
