To connect these terminals it is only necessary to take the Wiegand 0 and 1 and at least one GND from the SF-AC3011 to the controller. If the SF-AC3011 is powered from the controller, it is also used for this GND connection
The SF-AC3011 must be in a version like the following or later
The Wiegand connection of the SF-AC3011 must be configured as Sender (Send), this can be done either in the menu of the unit itself or with the SCC:
IMPORTANT: what the SF-AC3011 sends is the card number associated with the user, so it will be essential that users carry a card, which can be invented. Depending on the type of Wiegand you set, whether 26 or 34, the number of digits of the card you add to the user will change:
- Wiegand 26 - 8 digits
- Wiegand 34 - 10 digits
If the created users do not have this amount of digits in the card, when registering, the terminal will not send the information by Wiegand. In this example with Wiegand34 the users have 10 card digits:
Once these configurations have been made when adding the users to both the reader and the controller, the event is received in the two devices and the relay acts in the controller when it receives the card number and the user has access permissions
If, on the other hand, the SF-AC3011 Wiegand26 had been configured in the SF-AC3011, the digits of the card would have to be 8.
