2.1 Supplying power to the MR52

The MR52 accepts 12 to 24 V DC for power on TB7 (VIN and GND). Locate the power source as close to the MR52 as

possible.

Make power connection with minimum of 18 AWG wires.

Observe POLARITY on VIN!

The VOUT terminal on TB7 is the same as VIN.

2.2 Communication wiring (SIO communication port)

The MR52 communicates with a HID Mercury Security intelligent controller (EP2500 for example) via a

2-wire RS-485 interface. The MR52 allows for multi-drop communication on a bus of up to 4,000 feet

(1,200 m). Use twisted pair (minimum 24 AWG) with drain wire and shield for communication.

See Specifications.

Install RS-485 termination jumper, J4, on the interface boards at each end of the communication line only.
