put of the control unit (but with different address), and receive the same
radio signal transmitted by a transmitter, they generate two different ID

n 03. At this point, check in the control unit manual if and how it is pos-
sible to manually configure the various fields comprising the WIEGAND
message received by the control unit (this would subsequently allow
you to distinguish each information contained in the WIEGAND mes-
sage). u If this option is available: refer to Chapter 5 (of this manual)
to identify each information which comprises the WIEGAND message.
Lastly, enter this information in the software of the control unit. u If
this option is not available: the user will be able to read the ID of the
WIEGAND message by means of the software of the control unit, but
he will not be able to display the second level information (the code of
the transmitter which sent it, the button which has been pressed, the
address of the ETWI device which communicated with the control unit)
contained in the message.

n 04. On the control unit: after the ID of the transmitter has been ob-
tained, use the control unit management software to associate this ID
to the name of the user which will be using the transmitter. After this,
refer to the manual of the control unit to configure the options allowed
to each user (ID): for example, the access permits to entrances/exits,
the time slot in which the access is granted, the "anti-passback" safe-
ty function etc.

5 - FURTHER DETAILS

The data formatting of a WIEGAND message is shown in Tables D,
E, F and G. Each table shows how the bits of a specific bit-mode are
structured.
3 – English
• Table D - Data transmitted in 26 bit mode. The even parity is cal-
culated on the first 12 bit (from the 2nd to the 13th included). The odd
parity is calculated on the last 12 bit (from the 14th to the 25th includ-
ed). MSB = more significant bit, LSB = less significant bit.
• Table E - Data transmitted in 30 bit mode. The even parity is cal-
culated on the first 14 bit (from the 2nd to the 15th included). The odd
parity is calculated on the last 14 bit (from the 16th to the 29th includ-
ed). MSB = more significant bit, LSB = less significant bit.
• Table F - Data transmitted in 34 bit mode. The even parity is cal-
culated on the first 16 bit (from the 2nd to the 17th included). The odd
parity is calculated on the last 16 bit (from the 18th to the 33rd includ-
ed). MSB = more significant bit, LSB = less significant bit.
• Table G - Data transmitted in 37 bit mode. The even parity is cal-
culated on the first 18 bit (from the 2nd to the 19th included). The odd
parity is calculated on the last 12 bit (from the 19th to the 36th includ-
ed). MSB = more significant bit, LSB = less significant bit.
WARNING! – ETWI organises the data of the WIEGAND message ac-
cording to the mode which the installer selects depending on the con-
trol unit model (one among 26, 30, 34 and 37 bit modes). In some
cases, regardless of the data formatting compatibility (i.e. the chosen
mode is that required by the control unit), some control unit software
hide or do not consider part of the message and this may cause sys-
tem malfunctions.
