How to Set Up & Manage Cards

Initial Card Setup

1. Power off the device. Connect the S1 jumper cap to pins 2–3, then restore power. Wait for the green LED to flash three times.
2. Consecutively swipe two blank cards (the first card becomes the "Add Card"; the second becomes the "Delete Card"). The red LED will flash in short bursts to confirm.
3. Power off again, reconnect the jumper cap to pins 1–2, restore power — your master cards are now registered.

Adding Users

In standby mode: swipe the Add Card → swipe the user card(s) you want to register → swipe the Add Card again to exit.

Deleting Users

In standby mode: swipe the Delete Card → swipe the user card(s) to remove → swipe the Delete Card again to exit.

Delete All Users

In standby mode: swipe the Delete Card → swipe the Add Card → swipe the Delete Card to exit. All registered users will be cleared.

Ideal Applications

• Apartment building intercom systems
• Office and commercial door access control
• Embedded OEM access control projects
• Multi-unit residential entry systems
• Standalone single-door controllers
