Some NETNodes (the AVI variant) are able to use composite cameras. To do this they have
an extra Video / Audio and data encoder board fitted inside the unit.
To ensure the NETNode recognises and uses the internal encoder card we have to set the
auxiliary address to 1. Now your composite camera can be used with the system.
Caution: If you ever reset defaults on the NETNode it will reset the Auxiliary Address to
zero. You must reset this to 1 for your composite camera to work.
4.4.4. Relay Only
Normally each NETNode will have at least one source of sensor data attached to it, for
example, a camera or a microphone.
However, occasionally the NETNode only needs to act as a relay, for example, when you are
setting up a chain network for range extension or working with a helicopter relay.
In this case you would check the Relay Only check box.
Note: When the Relay Only check box is checked it simply disables any Ethernet
connectivity to the NETNode.
4.4.5. Speed Units
If you have a GPS connected to a NETNode it can supply speed data. You can choose the
units you want to use for speed in this combo box. The possible choices are:
 Knots
 MPH
 KPH
4.4.6. Streaming Protocol
This allows either multicast (raw UDP) or RTSP streaming (RTP multicast/unicast) of the
internal video encoder. See Section 5 on Streaming as this explains the intricacies of Video
streaming over IP in more detail.
4.4.7. DHCP Enable
In some situations having DCHP enabled may be appropriate for advanced users of the
system but in most cases it‟s better if each NETNode has its own fixed address. Fixed IP
address allocation is better when a system is in a dynamically changing environment as
operation is such an environment means that connection to the DHCP server can not always
be guaranteed.
If checked, then the NETNode will try to acquire its IP address from a DHCP server on the
network – this DHCP server can be located through another NETNode over the radio
interface.
4.4.8. IP Address
If the NETNode is not automatically acquiring its IP address via a DHCP server then a fixed
IP address needs to be assigned to the unit. This address is typically obtained from a
