Networks
Only visible if the internal wireless is in Client Mode when the device is selected. Shows a list
of all networks (hotspots) available for connection. Select the name of the desired network to
enter its network key and connect to it.
Network Name (SSID)
Displays the name of the internal wireless network.
Only visible if the internal wireless is set to Access Point (Internal Wifi) mode when the device
is selected. You can select it and change the internal wireless network to any name you want
for easy identification.
Network Key
Required by the smartphone or tablet to connect to the internal wireless network.
Only visible if the internal wireless is set to Access Point (Internal Wifi) mode when the device
is selected. You can select it and change it to increase network security. The key must be at
least 8 characters.
Channel
Only visible if the internal wireless is set to Access Point (Internal Wifi) mode when the device
is selected. Select it to change the Channel setting to overcome potential interference to the
internal wireless by another RF device transmitting in the same frequency band.
Restore defaults
Deletes all user made changes, and restores the wireless to factory settings.
Client settings
Opens the Wireless Client Settings dialogue, which shows networks previously connected to,
regardless of whether they are currently visible or not. Allows deletion of a network from the
list, and toggling of Automatic connection setting.
Advanced
Tools are available within the software to assist in fault-finding and setting up the wireless
network.
Iperf
Iperf is a commonly used network performance tool. It is provided for testing wireless
network performance around the vessel so weak spots or problem areas can be identified.
The application must be installed on and run from a tablet device.
The unit must be running Iperf server before initiating the test from the tablet. On exiting the
page, Iperf automatically stops running.
DHCP Probe
The wireless module contains a DHCP server that allocates IP addresses for all the MFDs, and
Echosounder in a network. If integrating with other devices, such as a 3G modem or satellite
phone, other devices in the network may also be acting as DHCP servers. To make it easy to
find all DHCP servers on a network, dhcp_probe may be run from the NSO evo3. Only one
DHCP device may be operational on the same network at a time. If a second device is found,
turn off its DHCP feature if possible. Refer to the device’s own instructions for further
assistance.
Ú
Note: Iperf and DHCP Probe are tools provided for diagnostic purposes by users familiar
with network terminology and configuration. Navico is not the original developer of
these tools, and cannot provide support related to their use.
Simultaneous Client and Access Point operation
If it is desirable to have the MFD accessible to a tablet while also having internet access, it is
necessary to use two wireless units - one must be in Client mode, the other in Access Point
mode. This can be a combination of internal wireless and an external WIFI-1, or two external
