The N2KView licenses are managed with the Hardware License Key which is connected to either:
            1) a Windows PC running N2KServer, or
            2) an IPG100 Internet Protocol Gateway running N2KServer.

You can upgrade N2KView key to increase the number of clients which can be connected at one time or add new features to your existing system. The first step in this process is to purchase an upgrade certificate. You need to purchase one certificate for each connected client or feature you wish to add. Following are the part numbers that are required:

Model #    Product Description   
N2KView-Add    N2KView (Additional N2KView License added to Existing N2KView-Base)   
N2KView-Alerts    Alerts Module (Each Alerts Module requires corresponding Base or Add License)   
N2KView-Video    Video Module (Each Video Module requires corresponding Base or Add License)   
N2KView-Control    Control Module (Each Control Module requires corresponding Base or Add License)   
N2KView-Fuel    Fuel Management Module (Each Fuel Management Module requires corresponding Base or Add License)

If you wish to add a feature or additional seats on N2KServer a single hardware license key, you can purchase all of the needed certificates at once and add all of the clients in a single step.

This article is for the situation in which one N2KServer IPG100 or a single USB100 are connected to a LAN with multiple N2KView clients. If you require two separate instances of N2KServer, you will need Windows PC’s with LAN connections, USB100 gateway devices or two IPG100 Internet Protocol Gateways running the embedded version of N2KServer.
You will then require two hardware license keys.

We advise upgrading to the latest N2Kserver available from our website. Check under the software updates section on the downloads page  (http://www.maretron.com/support/downloads.php).
 
Once you have purchased the certificate, please follow the instructions below (a similar set of instructions appears on the certificate as well).

If your installation uses N2KServer running on a Windows PC, then run the following steps using that PC.

If your installation uses an IPG100 Internet Protocol Gateway, you will need to install N2KServer on a Windows PC (the N2KServer installation contains the hardware license key upgrade tools) so that you can perform the upgrade. You may uninstall N2KServer after the upgrade is completed.

In order to begin the update of the license key, a "request file" must be created on a PC that has N2KServer installed. This can be done using the following instructions:

1) If N2KServer is running, stop it using the N2KServer Service Manager program.

2) With the hardware license key plugged into the system, click on Start->All Programs->Maretron N2KServer->Request and Install Additional Client Licenses

3) In the Secure Update Utility window that opens, under the Generate request category, click the Generate Request Code button and choose a filename for the request code.

4) A “Save As” window will appear. Under “File name:”, type a name to give the file, and then click “Save” to save the file containing the request code to your hard drive. Remember the name you gave the file. The file will have an extension of “.req” or “.req2”.

7) Save this file to the hard drive of the computer on which you’re running N2KServer.

8) Stop N2KServer if it’s running.

9) Start the Request and Install Additional Client Licenses tool (just as you did in step 2).

10) In the Secure Update Utility window that opens, click the folder icon in the “Update Hardware Key” section and browse to the electronic license file that you saved in step 7.

11) Click the Apply Code button. The hardware license key will be updated with the new licenses contained in the new license file. You should then see a “Success” message.

12) Start the Maretron N2KServer Service Manager program.

13) In the N2KServer Service Manager window, where the number of licenses are displayed, you should now see the additional license appear under the "available" column.

14) If you’re running the Windows PC version of N2KServer, you can go ahead and start N2KServer at this time, and the additional licenses will be available to you.

15) If your installation uses an IPG100 Internet Protocol Gateway, you can now unplug the hardware license key from the PC and plug it back into the IPG100. Turn the power to the IPG100 off and then on again so it will recognize the additional licenses.
