Setting up Floating License Manager

To set up Floating License Manager, follow the steps below:

  1. Install Sentinel Runtime (is included in the application package).
  2. Make sure that Sentinel LDK License manager service is up and running
  3. Ping the server from client machine and vice-versa.
  4. Go to "http://localhost:1947/_int_/config_to.html" on the client machine and enable all the checkboxes. Set server IP address in "Remote License Search Parameters" and click Submit.
  5. Disable all services of antivirus and firewall
  6. Port 1947 should be free on both machines

Setting up connection with Floating License Manager Service

To access Floating License Manager service from a local computer and obtain a required license, make sure that transmission of TCP and UDP packets on port 1947 (from the local computer to the License Manager) is permitted (not blocked).

To check if the packets are properly transmitted on port 1947, follow the steps below:

  1. Download a set of network scanning tools (e.g. nmap).
  2. Open a command prompt and execute:

>nmap.exe -sT -sU -p 1947 <ip address>

*(server IP address).

  1. As the result of network scanning, a message acknowledging TCP and UDP ports are open should appear:


Packets transmission block or improper network routing configurations can cause the port to remain closed. Packets block can occur in the system or in the network:

  • in Firewall configurations on a Client or on the server machine;
  • in antivirus application on a Client or on the server machine;
  • in various network hosts from a Client to the server.

Note, that if port block issues occur, contact your network administrator to solve the problems.

In case of issues, contact Elecard technical support department at
