3.3 WIEGAND 30 bit format
3.3.1
Programming Jumper
The programming jumper allows the user to modify several characteristics of the codes sent by the
MONO-S to comply with the specific needs of the host, and to increase the overall security level of the
system. The complete output data consists of several data blocks. The first block will indicate a group
number (4 bits) and can be used to emulate some special required code or a fixed header required by
the host. The 24-bit user code then follows. Of course the required parity bits are added.
3.3.2
Entering the programming mode
1. Open the keypad housing.
2. Place the jumper in it’s closed position.
3. Close the housing.
4. A long beep will be heard and the Yellow LED will light up. Wait until the beep stops. This should take
about 4 seconds.
5. Select the correct settings from the menu below.
6. Open the keypad housing and place the jumper back in it’s opened position.
7. Close the housing.

Once in the programming mode (step 5) you have the following menu at your disposal:
0 + (Group number) + A:
Programming of Group number (number between 0 to 15)
Note: When the sub-menu key (0) is pressed the bi-colour LED turns Green and, when this option is
validated, on pressing the “A” key, two beeps are heard and the bi-colour LED turns OFF.
Note: when using the 30-bit Wiegand format the highest code that can be sent to the host is limited to
16777215 (3 bytes = 24 bits). A higher code can be entered but will not be transmitted.

Note: P1 = even parity calculated over the bits 2 to 15 (A + X).
P2 = odd parity calculated over the bits 16 to 29 (Y).
4 bit group identification (number between 0 and 15)
E.g. Group N° 7 = 0111 (bit 2 = 0; bit 3 = 1; bit 4 = 1; bit 5 = 1)
