MR52 Dual Door Module Setup

MR52 Dual Door Module Setup

1.0 Introduction

MR52 S3


The MR52 dual door interface panel with on-board flexibility to connect to a wide range of security devices. The MR52 is easy to install and provides the required I/O for interfacing two card readers,

eight general-purpose input monitor points and six control relays to any Authentic Mercury series intelligent controller.

 

With two-wire RS-485 connectivity, the MR52’s two reader ports support OSDP, OSDP Secure Channel, FICAM government profiles, keypads, biometric readers, Wiegand, clock and data, magnetic stripe, F/2F and supervised F/2F reader technologies. System configuration and setup are provided through Mercury OEM partner software applications.

 

Borealis supports the use of Series 2 MR52 modules - the MR52 Series 3 is the latest generation door interface module for Authentic Mercury intelligent controllers, the platform of choice for customers seeking open architecture access control solutions.

 

 

 

3.0 Configure the RS-485 Address and Baud Rate

The S1 switch on the MR52 module is used to set the RS-485 address and the controller's baud rate. The first MR module that you add to the bus, by default, will be configured in the software as address 0 and the default baud rate is set to 38,400bps.

 

The S1 switch should have #6 and #7 in the ON position and all other switches are in the OFF position. This configures the controller as address 0 and the baud rate will be 38,400.

 

SW configuration

 

Use the S1 switch to change the RS-485 address (switches 1-5) or the baud rate (switches 6 and 7).

 

Because address 0 is a valid address on the 485 network, the second address will be address 1 (#1 in the ON position), the third module will be address 2 (with switch #2 in the ON position) - as highlighted in the following image.

 

MR Module Address

 

 

The comm address will automatically be set in the software based on the following rules:

 

  • The first module to be added to the controller's bus will be configured in the software as address 0. The second module added will be address 1, and so on.
  • Each of the controller buses can have up to 32 MR modules.
  • If you add modules to a different bus, again, the first module will be address 0 (because it will be a second, completely separate RS-485 network).

 

 

4.0 Add the MR52 Module in Borealis

  1. From the Borealis main menu, go to Hardware >> All.

    Main menu all

  2. Expand the controller located on the hardware tree.
  3. Select the TB port that the module is connected to.

    Note: Some controllers have 2 x TB ports (TB2 and TB3), whereas other controllers only have 1 x TB port (TB3).

  4. You will see the port properties located on the right-side of the screen.
  5. Click the ADD PANEL button.
  6. Select MR52 from the drop-down list.
  7. Click the SAVE button.

    Add MR52

  8. Expand the controller port and then select the new module.
  9. The MR52 properties will displayed on the right.
  10. If the module is addressed correctly it should show as online.
