MR16IN Module Setup

MR16IN Module Setup

1.0 Introduction

MR16IN S3


The Authentic Mercury MR16IN module enables expansion of Authentic Mercury intelligent controllers by offering 16-general purpose input circuits and two-programmable relay outputs. Borealis supports the use of Series 2 MR16IN modules as well as the new Series 3 enhanced modules - which offer an improved processor, increased memory plus an embedded crypto memory chip that provides a secured layer of encryption to onboard sensitive data.

 

The MR16IN module can be used for a variety of applications, such as monitoring doors that do not have access control or you can also use the I/O linkage functionality to activate outputs from dedicated general purpose inputs.

 

 

3.0 Configure the RS-485 Address and Baud Rate

The S1 switch on the MR16IN module is used to set the RS-485 address and the controller's baud rate. The first MR16 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 MR16 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 MR16IN 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 MR16IN from the drop-down list.
  7. Click the SAVE button.

    Add MR16IN

  8. Expand the controller port and then select the new module.
  9. The MR16IN properties will displayed on the right.
  10. If the module is addressed correctly it should show as online.
