Advanced Settings:
Automatic frequency selection mode
(DIP switches – all OFF for automatic mode
)
The AW-900x is designed to automatically select and continuously optimize the
performance of its radio channel. The radio channel is monitored to ensure it is
providing low error rates necessary for successful radio transmission. In the event that
the error rate rises, the AW-900x will autonomously change to a new channel. There
are 12 non-overlapping channels.
Manual frequency selection mode
To restrict the operation of the AW-900x to a subset of the 902-928 band, the user
may activate a manual selection mode that allows the radio to automatically choose
the best channel
within a grouped subset
of the 12 available channels. This is enabled
by the 8 position DIP switch on the master unit. These settings allow the AW-900x to
operate on the optimal channel in one of three subsets, LOW 4, MID 4 or HIGH 4. The
DIP switch setting are:
Channels
DIP Setting
Frequency
LOW 4 - 1,2,3 or 4
2 On / 3 Off
902-910 MHz
MID 4 - 5,6,7 or 8
2 Off / 3 On
910-918 MHz
HIGH 4 - 9,10,11 or 12
2 On / 3 On
918-927 MHz
Or - the user may wish to select
a specific channel.
This can be done by setting DIP
switches 5-8 as shown in the table below. [Turn DIP 2 Off / 3 Off]

Site survey mode
(
DIP switch 4 -
default is OFF for normal operation
)
In this mode the AW-900x can perform a site survey. With this mode activated the
radios send and receive at 100% capacity by transceiving self-generated simulated
data. The installer can monitor the Link Quality display to assess channel quality while
optimizing antennae orientation. The installer can manually select each channel to
evaluate performance and identify the best channels for operation. By identifying
channels with poor performance it is possible to identify possible interferers and use
“manual frequency selection mode” to avoid portions of the band or select a fixed
operating frequency.
Note:
Ethernet traffic does not get transported while the radios
are in this mode.
Power save mode
(
DIP switch 1 -
default is OFF for normal LED display
)
In this mode the display LEDs can be turned off for low power applications (solar).
