26 Bit Wiegand Data From EM Cards
26-bit EM Card is the most popular one on the market. Almost all the controllers can use the 26-bit
standard format.
A 26 bit Wiegand protocol for card reading has 1 first parity bit, 24 bits of the Card ID, and 1 stop
bit for a total of 26 bits. The first parity bit is an Even parity bit calculated from the first 12 bits of
the code and the trailing parity bit is an Odd parity bit from the last 12 bits. The data output is in
Hex Binary codes.
Each EM card or Keyfob is marked with an unique ID in Decimal Digits that is the code read by the
reader. The EM Card is also marked with a “3 digit + 5 digit” code that are the site code and ID
number arrangement of the Wiegand data.
EXAMPLE:
a) The Code Marked on One of The EM Cards:
19
b) Each Hex Number Consists of 4 Bits, Total 26 Bits of Wiegand Data Output from Card Reading:
E 6 4 E B 1 3 O
An Even Parity Bit of 6 4 E = 0 An Odd Parity Bit of B 1 3 = 1
c) The 26 bits Wiegand Data Sending Out in Hex Binary from Reading The Card:
0 0 1 1 0 0 1 0 0 1 1 1 0 1 0 1 1 0 0 0 1 0 0 1 1 1
The ID Code to be read for Wiegand Output The Code does not belong to this system

The Site Code and the ID number
The Code in Decimal Number : 6 6 1 3 7 7 9
The Code 6 6 1 3 7 7 9 Equivalent to Hex Number : 6 4 E B 1 3
d) The Arrangement of The Site Code and ID Number of A 26-bit EM Card:
● Site Code: Bit 2 ~ 9 (000~255)
● ID Number: Bit 10 ~ 25 (00000 ~ 65,535)

3) Pause The Scheduled Daily Inhibition for Output 1 (Temporarily Disable The Inhibition)
The scheduled inhibition can be programmed and applied to Output 1 with daily start and stop times.
It can be stopped temporarily if required; such as the staff work overtime after office hours going
into the inhibition period. This function Starts / Stops in toggle with the following code entry. It can
be done before or during the inhibition period.
---------- Door Lock Operation Resumes, Start / Stop in Toggle
NOTE :
• The “INHIBIT” LED (Red) is ON in inhibition and turns to Flashing while pause is into effect.
•
See Programming Locations 55 & 56 for more information Daily Inhibition.
4) Inhibit All The User Codes & EM Cards for Output 1 (Disable Access Control Manually)
To enhance the security of the access control keypad, the owner can stop the keypad after office hour
or while the house is nobody inside. Once the Output 1 (for door lock control) is inhibited, all the User
Codes / Cards for it become invalid and those people holding the User Code or Card are refused. This
function Starts / Stops in toggle with the following code entry.
------ Door Lock Operation Inhibited, Start / Stop in Toggle
NOTE :
•
The door is locked during Output 1 inhibited and the “INHIBIT” LED (Red) is ON.
•
Inhibition applies to all User Codes and EM Cards for Output 1 only. Output 2 and output 3 are not
affected.
SUPER USER CODE
REMARK :
While SUPER USER CODE
 
is in operation to hold the door lock open, the functions that
rely on the door sensor (such as a magnetic contact) and the User Codes for output 1 are all
temporarily suspended until SUPER USER CODE
 
is keyed in again to release the door hold
function.
The following are the temporarily suspended functions:
● Door Auto-relock
● Door Forced Open Warning (at Location 80)
● Door Propped-up Warning (at Location 81)
● Door Opening Alarm (at Location 91)
● Dual Keypad Inter-lock Operation
● All User Codes Including Super User Code for Output 1
● Duress Output Actuated by The Duress Code for Output 1
