4. Enter the <A440_ID> BLST command and wait for the response,
which shows you the heard responses of the broadcast sent by
the RA440.
5. Pick the RTUs that will communicate with the RA440. Check every
RA440-RTU connection by entering the <RTU_ID> INFO
command, where RTU_ID is the serial number of the RTU picked
from the broadcast response list.
6. Check the radio link quality of the connection displayed at rf_in
and rf_out at the ping response. For a good link quality to a
Series 3 RTU, the value must be at least 200. See “INFO” on
page 43 to pick the RF indicators.
7. If all of your ping commands respond with a good radio link
quality, the proper function of the RA440 at this position is
ensured. If one or more radio links did not pass the threshold,
reposition your RA440 or route the communication via other,
nearby, radio units.
