Setting up multiple WIFI-1 units
On large or metal hulled vessels it may be necessary to connect multiple WIFI-1 access points
to extend the range.
Up to 2 WIFI-1 units can be connected to one NSS, but only the WIFI-1 unit defined as primary
access point can be used for connecting the wireless device to the NSS.
1. Open the access points dialog as shown above
2. Activate the line for the connected WIFI-1 unit, and re-define this to be a secondary access
point
3. Connect and define the additional WIFI-1 unit as described in “Setting up the WIFI-1” on page
13.
- The latest connected WIFI-1 unit will now be the primary access point, and only this can
be used for connecting the wireless device to the NSS.
Selecting communication channel
The WIFI-1 unit will automatically select the channel used for communication with the
wireless devices.
You might need to change the channel if other transmitting devices cause conflicts (multiple
networks, wireless phones etc), or if you are using the equipment in areas with restricted
channel selection.
The channels can be manually changed from the drop down list.
¼ Note: Only technically skilled persons should set up multiple WIFI-1 units or change the
communication channel!
Connecting the wireless device to the WIFI-1
Set up the wireless device’s network to be the WIFI-1 defined as primary access point.
- The Network name is found in the NSS menu. Refer to “Setting up the WIFI-1” on page
