The E-CODER)R450 i Config Email provides feedback on the RSSI values between the
E-CODER)R450 i and the collector following MIU activation. Depending on the RSSI values
recorded, the system indicates the following values:
l
Pass.
l
Marginal.
l
Fail.
RSSI values in the Pass range are required for both the Uplink and the Downlink to ensure
full, two-way capabilities of the E-CODER)R450
i as part of the R450 System. For more
information, see the next two tables.
