OPTION 1 Connect with LAN (wired)
The Local Area Network (LAN) port is a 10/100 Ethernet 
interface with an RJ45 jack for connecting the controller 
to a LAN in order for it to gain connectivity to the Internet. 
Use a straight, (i.e., non-crossover) cable to connect to 
a local hub, switch or router. Connect the Power/Internet 
Board to a LAN functionality is a supplementary feature.
1.   Connect an Ethernet cable from your LAN to the LAN 
port on the Power/Internet Board. When connected 
properly, the green and amber LED on the Ethernet 
port will light/fl icker. If the green LED is not lit, check 
the connections on the controller and the Ethernet 
hub. 
2.   On the display, select Wired Network if dynamic 
confi guration (DHCP) is desired or select Manual 
Setup for a static IP address.
OPTION 2 Connect through Wi-Fi® (Wireless)

Gate Access (Wired)
Disconnect power BEFORE making electrical connections. Below is an example of a wiring setup for gate access. Gate access can 
be wired to Door 1, 2, 3, or 4 on the Door Boards. LiftMaster® Security+ 2.0® gate operators can also be programmed to communicate 
wirelessly instead of using a wired connection (refer to the following page).
NOTE: The length of the unshielded

Wiegand Proximity Reader
The controller is designed specifi cally for the HID PROX-POINT+ MINI READER proximity reader to be mounted on the faceplate.
1. Disconnect power.
2.   Remove the mounting plate and gasket from the controller.
3.   Use a bench vise with soft jaws to hold the mounting plate and 
drill a hole for the cable with a 5/16" drill bit.
4.   Drill two mounting holes with a 7/64" drill bit. Make the 
threads using the self-tapping screws provided with the 
HID reader. NOTE: Thread the screw and remove. Clean the 
mounting hole thoroughly until the entire thread is made.
5.  Reinstall the gasket and mounting plate onto the controller.
6.  Install the proximity reader and secure with the screws.
7.  Apply silicon around the cable hole.
8.   The proximity reader can be wired to any of the 4 Wiegand 
Inputs on the door control boards. Insulate any unused wires 
from the controller to prevent a short. (Refer to instructions 
supplied with your Wiegand device for more information.)
9. Connect power.

Disconnect power BEFORE making electrical connections. The controller offers a Wiegand output capable of 26 bit transmission of the 
following data:
•   Success Call with access granted by the resident. The controller will provide a LMC specifi ed facility code followed by the Directory 
Code of the resident that granted access.
 And/Or
•   Successful access through Entry Code. The controller will provide a LMC specifi ed facility code followed by the successful Entry 
Code. 
The two facility codes should be different to prevent duplicate code transmission with the Wiegand Output.
