Apply 12 VDC power to the board. The LNL-3300-M5 consumes approximately 300mA (plus card reader loads).

Detailed wiring diagrams and mounting instructions are available in the official or via digital repositories like Scribd .

Place the LNL-3300-M5 onto the mounting standoffs within the M5 enclosure. Secure it using the provided screws. Ensure there is adequate clearance for wiring and that the board does not touch the metal sides of the box. Step B: Wiring the Power

With the hardware installed, you must configure the controller's network identity and communication settings. This is primarily done using the .

The is a high-performance, IP-based access control panel designed specifically for retrofitting legacy CASI M5000 and M3000 systems.
