While the New Mx Controller Wizard is the preferred way to discover and set up a Mx controller and its associated devices, you can add additional doors and points to an existing controller using the Mx controller right-click option.
Step 1 Right-click an existing MX controller on the system tree and an option list like this appears.
Step 2 Click Edit... to bring up the Mx Door Properties.
Step 3 Make changes and add points and doors as required.
Step 4 When you have entered the values you need, click Finish.
Step 5 Apply configuration changes to the controllers in this system.
