Wire Replacement I/O (900 MHz): User Manual and Reference Guide
l
High noise levels can often be mitigated with band pass filters, antenna placement or
antenna polarization.
6.6 Number of Disconnects
Anytime the link between the Master and the Slave is broken and the radios lose Carrier Detect.
l
The value indicates the total number of disconnects that have occurred from the time the
radio is powered on until the radio is put into
Setup
mode.
l
Under ideal operating conditions, the number of disconnects should be
0
.
l
One or more disconnects may indicate a weak link, the presence of severe interference
problems or loss of power to any of the radios in the link.
Note
: In
Tool Suite
, the disconnect information is available in the
Summary View
in the
Network
Diagnostics
application.
6.7 Radio Temperature
The
Radio Temperature
value is the current operating temperature of the radio in degrees
Celsius.
FreeWave Recommends
: For proper operation, a FreeWave radio must be in the temperature range
of -40° to +75° C.
Some of the radios are only tested to 0° C.
Note
: See the radio specifications in this document for details.
6.8 Rate %
The
Rate %
measures the percentage of data packets that were successfully transmitted from the
Master to the Slave on the first attempt.
l
A number of
75
or higher indicates a robust link that provides very good performance even
at high data transmission rates.
l
A number of
15
or lower indicates a weak or marginal link that provides lower data
throughput.
l
A
Rate %
of
100%
provides approximately:
l
100 Kbaud of bandwidth with an
RF Data Rate
setting of
3
.
l
150 Kbaud of bandwidth with an
RF Data Rate
of
2
.
l
These numbers are reduced approximately 50% if one or more Repeaters are in the
network.
