Software setup | HDS Gen3 Installation Manual
Mode (WIFI-1 only)
When more than one WIFI-1 device is
connected (i.e. on large installations), only
one may operate as ‘Primary’. Primary mode
determines that the device is acting as
DHCP server - only one DHCP server may
exist on a network at a time.
To set a device as secondary, the HDS Gen3 must initially be
connected to only one WIFI-1 module, which should be set to
‘secondary’. Once completed, a second module may be plugged in,
which will automatically default to primary.

Note: Use of multiple devices is solely for range extension purposes,
and is usually only required on larger vessels.
Channel
Channel setting is available in order to
overcome potential interference to the
GoFree device by another RF device
transmitting in the same frequency band.
Advanced
Tools are available within the HDS Gen3
software to assist in fault-fi nding and setting
up the wifi network.
Iperf
Iperf is a commonly used network performance tool. It’s provided
for testing wireless network performance around the vessel so weak
spots or problem areas can be identifi ed. The application must
be installed on and run from the tablet device. The HDS must be
running Iperf server before initiating the test from the tablet. On
exiting the page, Iperf will automatically stop running.
DHCP Probe
The wireless module contains a DHCP server that will allocate
IP addresses for all the MFDs, radars and sonars 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 fi nd all DHCP servers on a network, dhcp_
probe may be run from the HDS.
