  • Required Settings:

       Mode: Single

       Address: Server IP address (Example: 192.168.1.1)

       Port: 49110 (Only change it when this port is used by another application).

       Windows User: Everyone


Scenario (3)

  • Scenario description: Two redundant servers on two redundant machines.
  • Required Settings:

       Mode: Redundant

       Server address: Server IP address of the local machine (Example: 192.168.1.1)

       Port: 49110 (Only change it when this port is used by another application).

       Check interval (ms): time interval between each check. Both servers will check on each other using this time        interval
