How to discover and change the IP address of your SPRINT-Nav Mini

Before changing the IP address of your SPRINT-Nav Mini, the current IP address must be known to allow connection to the WebUI.

If connection attempts are unsuccessful with the default IP address, follow the steps below to obtain the current IP address.

Discovering the IP address

If the IP address of your SPRINT-Nav Mini is unknown, the following method can be used to find it.

1. With the SPRINT-Nav Mini powered down, establish an RS232 connection using a terminal package, such as 6G Terminal Lite. The port should be at the default baud rate of 9600 (8 data bits, 1 stop bit, no parity).
2. Power the SPRINT-Nav Mini with 24 V dc applied to Port A. The SPRINT-Nav Mini will then begin to boot. After approximately 90 seconds, the SPRINT-Nav Mini will report the IP address that it has been set to.
3. In the example below, the SPRINT-Nav Mini IP address is set to 192.23.46.10

Establishing a connection

Once the IP address of the SPRINT-Nav Mini is known, the next step is to establish a connection via ethernet.

1. Ensure that the computer being used to connect to the SPRINT-Nav Mini has the correct adaptor settings to match the network of the SPRINT-Nav Mini.
2. As the unit has an IP 192.23.46.10, the computer must be set to 192.23.46.xx (where xx is any value except 10, which is reserved for the SPRINT-Nav Mini).

3. Open a browser on the computer and input the IP address of the SPRINT-Nav Mini.
4. The WebUI will now appear with the connection established.

Changing the IP address

Once the connection has been established to the SPRINT-Nav Mini, it is now possible to change the IP address (if required).

1. On the WebUI, navigate to System > Network > Network Settings and then click/tap Change.
2. A dialogue box will appear where the desired IP address, Subnet Mask and Gateway can be input.
3. Ensure the new values have been noted, otherwise the steps in Discovering the IP address will need to be repeated.
4. In the example below, the default values have been input.

1. After Apply is clicked/tapped, communication with the SPRINT-Nav Mini will be lost since the address has changed.
2. Repeat the steps in Establishing a connection, with the new IP address values applied.
3. The example below shows the WebUI with a connection now established on the default IP address of 192.168.179.10
