8. Once a radio is configured as the master it will establish a RF communication with the second
radio. To verify this connection type:
> monitor-link clear=1
Verify that the status shows “MASTER IN SYNC”, the receive packet count is increasing and no
error counts are counting up.
9. The terminal connected to each radio can be used to further modify the radio’s operating
parameters. Section 5 describes the command language used to perform those functions.
4.3 Field Installation
4.3.1 Configuration
The AR24027 units are shipped pre-configured with a factory default configuration. If the unit
configuration has been altered, you can always reload it with the command:
> load factory
The factory configuration sets the TDD synchronization mode to “auto”. If the units are paired with a
NetCrossing Gateway no changes need to be done to the configuration. If the radio is intended to
operate standalone, one of the radios need to be configured as the master, by issuing the command:
> tdd sync=master
This is all that is needed for two radios to establish a point-to-point link. Some other parameters that
you may want to modify, and the commands to modify them, are listed in the table below. Refer to 5
for a complete list and description of all parameters.
Parameter Command Comments
Transmit Power rf-transmit-setup The factory default is 18 dBm. You may want to adjust
it up or down to achieve a specific link margin. When
adjusting the power up, keep in mind the restrictions
described in section 4.3.5 and 4.3.6.
Channels rf-transmit-setup
rf-receive-setup
The transmit and receive channels may be different from
each other. However the transmit channel of one unit
must match the receive channel of the other unit. See
section 4.3.4 for guidelines on how to select the
operating channels.
Speed rf-transmit-setup The factory default is 2.75 Mbps. The only reason to
reduce the speed is for very long range links, or under
interference, to take advantage of the higher sensitivity
at lower speeds.
