Signature message that contains a unique “signature” that the radio identifies
with when receiving messages. Any message with a different
signature is ignored.
Depending on the country this selection will be varied. USA,
Australia, New Zealand and India will have a selection of 4
signatures (0, 1, 2, 3) while Europe, 5mw and 500mw models have
just ‘Normal’ and ‘Compatible’.
All modules must have the same Message Signature to successfully
communicate.
Hopset
From here you can select from available Hopset or band, The
selection is country code specific, i.e. US/Canada have 2 bands
available, Low (902-914MHz) and High (915-928MHz).
Australia, New Zealand and India only have the one band and will
indicate this by showing the country. European country codes will
indicate the configured frequency, i.e. 869.525MHz for 500mW
model and 869.875MHz for 5mW model.
Transmit Power
Mode
Adjust the Transmit power level from 30dB (1 W) to 20dB (100 mW).
See dBm to mW conversion table at Appendix A:
Data Rate
A selection of data rates is available depending on the country code.
Fixed Frequency model (EU) can use 14, 38, 56 and 76kbps while
the FHSS (US, AU, NZ and IN) use 19, 56, 76 and 115kbps.
Communicating radio can be configured with different data rate and
will communicate at whatever rate is configured. The main
advantage of using the higher date rate is an increase in speed
however this is offset by a decrease in range.
Disable Rx LNA
Check box to disable the LNA (Low Noise Amplifier)
Reduces the Receive Sensitivity by about 15dB, used during Demos,
Bench testing, or close communication paths, etc.
Save Changes
and Reset.
Save settings to non-volatile memory, and reboot WI-I/O 9-U2. Once
the module has completed the reboot sequence, all changes are in
effect.
4.4.5 Mesh Fixed Routes
In some radio systems there will often be a number of radios that will act as Repeaters
for the other radios. Because these sites are generally stationary they do not need to
learn the different paths and can be configured to have fixed route paths back to the
destination. We configure these routes with
‘Mesh Fixed Route’ rules.
You can configure up to 100 fixed Route Rules for each site and the rules can be
targeted to a specific IP address by using a Host Route or a complete Subnet.
Note: If configuring Fixed Routes and any part of the communication path
fails, i.e, path, module, etc there is no fallback to Meshing.
