To be able to use the routing software, you need a license key. This key is a string of characters you will receive either within the shipment on the project’s CD or by email directly from DHD.
This license is valid either for a RM4200D DSP frame or for a specified PC. In the former case you can connect from different PCs to the licensed DSP Frame. In the second case, you can run the software limited to one licensed PC, but with the possibility to control any DSP frame.
In every case the license key is based on the last 3 byte of the ethernet chip’s MAC address of the respective device.

If you order a license key for the routing software, you should have the MAC address of your PC or the according DSP Frame present. | |
Additional information about entering of license keys are mentioned in a later chapter. (see also Enter license)
If you get a license key for a certain DSP frame, you may install the routing software on any number of PCs. However, these PCs can only communicate with the licensed DSP frame.
You can detect the last 3 byte of the MAC adress as follows:
Start the Toolbox4 software and open the Maintenance Window. Starten Sie die Toolbox4-Software und öffnen Sie das Maintenance Fenster. In the left part of the window you will see a list of all RM4200D devices available in the network. For every device, a 6-digit code is listed right beside its name and project ID.
Another way to find out the three byte of the MAC address is to display the modul information of the RM420-850 Communication Controller. Select the according module in the device tree and press key F11. A new window displays the detailed module information, wherein you can find the 3 byte of the MAC address in line MAC address.

If you need to exchange a communication controller module RM420-850, the spare module comes with another MAC address. This may invalidate your software’s license code. Should this be the case, you need to order a new license code from DHD. Please specify the last 3 byte of the new controller’s MAC address within your order. | |
Aternatively, the routing software can be licensed for a certain PC. That is useful, if you would like to manage several RM4200D DSP Frame from one single PC. For ordering a license, you need the MAC address of your PC. Please follow these steps to detect your PCs MAC address under Windows XP or Windows 2000:
Click on Run in the Windows Start-Menu.
In the opening dialog box, enter cmd and press the OK button.Enter Geben Sie im Eingabefeld den Befehl cmd ein und klicken Sie den Button . A command line window opens.
At the prompt, enter ipconfig /all and press Enter.
The current configuration of your PC’s network interface is displayed. Search for the entry Physical address. On its right side, you will find the MAC address formatted like ab-cd-ef-gh-ij-kl. Please use this string for the request of a license code.
