Here are the specific instructions regarding the configuration typically found in that manual supplement:
The installation process for the LNL-3300-M5 is a straightforward "rip and replace" migration: Power Down
: Safely shut down the legacy controller and disconnect the 12 VDC power source.
: The M Series boards are specifically designed to fit into existing CASI enclosures, requiring only a straightforward swap of the legacy boards with new Lenel hardware. Power Requirements : Operates on 12 or 24 VDC input power.

The LNL-3300-M5 is an that acts as the primary "brain" for access control.
Regularly backup your OnGuard database and controller configurations.
Dedicated serial port for diagnostics or configuration.
Before installation, familiarize yourself with the board’s key connection points:
If the LNL-3300-M5 is the physical first or last device on the RS-485 bus, install a 120-ohm resistor across the data lines or activate the onboard termination jumper. Hardware Configuration (DIP Switches)
Before beginning the installation, ensure your power supply and environmental conditions meet the following requirements: 12 to 24 VDC ± 10%, 300 mA maximum.
