For example, if the user enters:
**123456789012345678901234567890123,
The door sends:
12345678901234567890123456789T
to its KeypadString attribute.
z
The user can enter asterisks within the string if needed. These
asterisks are converted to periods when sent to the door’s
KeypadString attribute.
For example, 69*8*6310 is converted to 69.8.6310 when sent to the
door’s KeypadString attribute.
z
If more than 4 seconds elapse between keystrokes, the door exits
escape sequence mode. The user must begin the process for string
input again.
z
If a user presents an access card to the card reader while the door is
in escape sequence mode, the door exits escape sequence mode. The
user must begin the process for string input again.
PE Feedback to the Door
After the PE program receives the string input and interprets its value,
the PE program assigns an appropriate value to the door’s
KeypadCommand attribute.
One of the following values is transmitted back to the door through its
KeypadCommand attribute:
z
0 — Disable keypad input at the door (default behavior for Door
Create )
z
1 — Clear string
z
2 — Recognize the escape sequence entry
z
3 — Do not recognize the escape sequence entry (fail)
z
255 — Enable keypad input at the door.
