As part of your installation, you might need to include a Mercury LP2500 intelligent controller.
IMPORTANT: LP controllers include a Micro USB port. This connection is not
to be used if UL/ULC listed access control system compliance is required and is to
be maintained.
The following diagram demonstrates how to connect the controller.
| A | Power In | Connect + to VIN (observe polarity). Connect - to GND. Use 20 AWG wires minimum. |
| B | Ethernet cable | Connect to the Synergis™ Cloud Link directly or through the network infrastructure. |
| C | RS-485 bus | RS-485 bus connection to other Mercury modules. |
