Figure 8: Successful check of network connectivity to the Control Board. The command entered by the user is highlighted, as are the important keywords that should be present in the output of the command "ping".

Verifying network adapter settings

Note: After a recent change of network settings, it can happen that the ping is not successful because the changes haven't propagated to the other participiants on the network yet. It can be sometimes remedied by running the command "ping" on the other computer, in this case, on the Control Board, pinging the IP address of the Host PC.

1. The subnet mask, 255.255.255.0, is the same for both.
2. The IP addresses, 192.168.42.100 for the Host PC and 192.168.42.123 for the Control Board, differ.
3. The subnet mask checks out as follows:
   1. The network address, 192.168.42.0, is the same for the Host PC and the Control Board.
   2. The host addresses, 0.0.0.100 for the Host PC and 0.0.0.123 for the Control Board, are different. In addition, neither is 0 nor the maximum value, 255 in this case.

Changing the IP settings of a network connection

Alternative method of viewing network settings: Open command prompt (see Figure 8) and execute the following command:

    ipconfig

It will list all netowork connections and their IP addresses.

To observe the IP address of the Control Board, open the USB serial console at the baud rate of 115200 shortly after powering up the Control Board. There should be boot messages on the console and they should contain the IP address shown on the following Figure:

In the case the boot message was not seen for any reason, the network configuration can be seen by logging in as "root" with the password "root" and executing the command "ifconfig" as shown on the following figure:

To start the motor, click the button "Motor". The motor will make 3 rotations in order to make sure that encoder finds the initial position before starting in correct mode and the button will turn red. To stop the motor, click the button "Motor" again; the button will turn green.

The Web UI running in a web browser on the Host PC enables use of the EDDP Kit from anywhere in the network.
