Preset Tab - Transmitter
Item
Range
Description
Enable
Set or clear
If selected, this turns the transmitter on.
All NETNodes in a Mesh must have their transmitters enabled.
Frequency
Frequency in
Megahertz
The transmit frequency for the system.
If an input frequency is out of range for the product, the radio will
tune to the lowest or highest available
frequency automatically.
Channel
Bandwidth
2.5/3.0/3.5/5.0/6.0
7.0/8.0/10.0MHz
The channel bandwidth for system.
If a lower bandwidth is used the operating range will increase.
If a higher bandwidth is used the operating range will decrease.
Output
Attenuation
0 to 30dB
The level of attenuation in dB that will be applied to the output. This
could be useful if the transmitter is swamping a
second unit nearby.
RF Output
Port
A, B or A+B
This will choose which of the output ports (or both)
will be used as a transmit port.
PA Linearity
Low, High
High linearity, improves COFDM shoulder
performance at the expense of power consumption.
Low linearity will have some saving in power consumption but
range expectations will be compromised.
ACRX Mode
Off, Uplink,
Downlink
Set to on to enable IP forwarding.
Interference
Avoidance
Off
Slave
Local Master
Interference Avoidance ensures the network switches frequency
automatically when channel interference is experienced.
If Local Master is selected, the transmitter frequency is replaced by
a Set button. If the Set button is clicked, up to eight preset frequen-
cies can be entered which are followed by all other Slave nodes in
the network. Slave nodes will have these values greyed out but be
viewable.
