AIROCKS PRO ARX-900 USER GUIDE V1.0
It is helpful to set up and turn on the Master unit before beginning the deployment of Relay units. This
will allow you to check signal and interference levels as you deploy Relay points. It is also helpful to
deploy Relay units starting closest to the Master and working your way “downstream”, while checking
receive signal level and interference at each Relay location.
5.9.6
ALO and RSA
Check ALO and RSA functions.
Once you have finished deploying Relay units, use the NMS to double check ALO and Remote Spectrum
Analyzer functions. Keep in mind that manually initiating an ALO re-scan will cause all downstream
nodes from that point on to re-scan and re-acquire an uplink signal. This exercise should NOT be done
during the event.
The same can be said for RSA (Remote Spectrum Analyzer). It is a good idea to perform a few RSA scans
during deployment to keep an eye on the local spectrum conditions at each Relay point. But, as
mentioned above, performing an RSA will take the unit off-line for ~.5 seconds causing all downstream
nodes to re-scan and re-acquire in uplink signal. RSA should NOT be performed during the event.
5.9.7
DC Power
Use DC battery pack if AC is not available
AirNetix offers an optional DC battery pack which will allow you to position Relay units in the field
before AC power is available (a common problems in large outdoor deployments). The DC battery pack
will power the AiRocks unit for up to 12 hours and will allow the installer to fully test the unit transmit
and receive functions.
