BluSKY Connect


On some take-over projects the standard method of connecting to a panel with very old firmware is painfully slow.  There is also an issue with very old firmware where the Integrator can not set the URL. This article will demonstrate a method for upgrading the firmware via the BluSKY connect PC utility. This method is only an alternative method for older equipment and has no additional benefit on newer boards.  Both methods will result in a panel having the latest firmware.


To begin, we need to set up the Mercury controller to be able to connect  to the software we will be using. The utility does not provide a lot of feed back and these steps may take some time to complete, please be patient. Repeated clicks can cause further frustration. As soon as the firmware is updated you will see a noticeable increase in UI responsiveness.

BEFORE GOING ONSITE: Please download the Mercury firmware upgrade utility (MSC  here

Setup PC

  1. Prepare a Windows computer, by connecting to the network and setting its IP address to

Configure Mercury Panel

  1. On the Mercury controller set dip switch 2 to ON and reset or power cycle the controller. This will put the board into its default communication mode and set the IP address to 
  2. In a browser (preferably IE or Edge), enter in the address bar. This is the default connection method set in the step above. 
    • Note: Depending on your browser configuration, you may have to push through browser warnings due to the lack of a HTTPS certificate. This is very common.
    • Note: Some users have reported issues using the Chrome browser. If you experience issues we recommend switching to another. IE and Edge seem to be the most reliable for this connection.
  3. Once you see the login screen, set dip switch 1 to ON. Waiting to throw this switch will ensure you have enough time to log in. Otherwise, you may miss the five minute timeout on the default login and password. 
  4. Click on the Host Comm. menu.
  5. Ensure that all of the following parameters entered as they appear below:
    • Connection Type:  IP Server
    • Data Security:  None
    • Port Number:  3001
  6. Click the Accept button
  7. Click on the Apply Settings menu option. 
  8. On the board, set dip switch 1 to OFF, then click Apply Settings.
    • Note: You will have to push past the pop-up notifications about one of the dip switches still being in the ON position.

Run BluSKY Connect Utility

  1. Unzip the file, if not already done.
  2. Run BluSKYConnect in the directory were the .zip was extracted.
  3. Select the correct model See Model.png
  4. IP Address: Set to IP Address of controller, if DIP 2 is set the IP address is
  5. Select Connect - See BluSKYCOnnect Connect png file
  6. Select Upgrade, it will take ~10 minute and reboot.
  7. Select Network, fill in network setting for your site.  See BluConnect Network.png
  8. BluSKY Port - set to 3012
  9. Security - None
  10. Select "Configure for BluSKY" - This will set the configuration to start communicating with BluSKY.
  11. Unset DIP 1 & DIP 2
  12. You should now see your system in BluSKY's MTT Tool (Add URL)

Run the Mercury Firmware Upgrade Utility

  1. Unzip the MSC file, if not already done, and inspect the contents. A couple of notes:
    • Folders EP1501 SCP_INIEP1502 SCP_INI and EP2500 SCP_IN. These folders contain .ini files that will serve as the default .ini files for the MSC Tester. 
    • The scp_sys file in the main folder is the one that is used by the MSC Tester executable. Always ensure that the scp_sys.ini file has the correct controller specified and that the IP address and port are entered correctly. If you are following these directions no modifications should be necessary, as the default port and IP address are already entered.
    • EP1501_X_X_X_XXXX_FW, EP1502_X_X_X_XXXX_FW and EP2500_X_X_X_XXXX_FW. These folders contain the most recent version of the hardware firmware. 
  2. Copy and paste the corresponding device's .ini file from the folder and paste it into the same folder as the MSC Tester executable
    • Note: If you use the wrong .ini file the Mercury Utility will not be able to connect to the device. 
  3. Run the MSC Tester.exe. Remember that the executable will use whatever .ini file is in the same folder.
  4. In the application, enter 1 in the controller#  text field. 
  5. Click the Download Firmware button and select the appropriate firmware update to apply to the controller. 
  6. Click Yes to begin downloading the firmware to the controller. Be patient, the output is very terse and it can take a few minutes to get any update.

Once the application has completed you should see a marked increase and performance through the normal HTTP connection method. This should make completing the network configuration for the controller much easier. Our guide on the Network Configuration for Controllers can assist if this is your first time connecting to BluSKY.
