Entering String Input from the Keypad

When a user enters string input at a keypad, the following process 

occurs: 

1. The user presents a valid access card and/or PIN (if a PIN is 

required) to the door reader.

2. The controller for this reader accepts the user’s credentials, and the 

door unlocks.

3. Within 3 seconds of the door unlocking, the user enters two 

consecutive asterisks (**) at the keypad to enter escape sequence 

mode. 

4. The keypad LED flashes slowly to indicate that it is waiting for 

input.

5. The user enters a numeric string of up to 30 characters (not 

including the two asterisks), then terminates the string with the 

pound sign (#).

For example: **10# or **6986310#

6. The door makes the string available to a PE program via its 

KeypadString attribute.

Entry Rules for String Input

The following rules apply when using a keypad connected to a door to 

enter string input:

z

After the door unlocks for a valid access, if more than 3 seconds 

elapse before the user enters two asterisks, the door exits escape 

sequence mode. The user must begin the process for string input 

again.

z

If a user enters more than 30 characters (not including the first two 

asterisks), the door detects when the 31st digit is entered. The door 

then replaces the 30th character with T to indicate Tamper, and 

sends the string to its KeypadString attribute (no # is needed). 

Subsequent characters entered as part of the string are ignored.
