Console Diagnostic Mode

Screen 1: Statistical Diagnostic Screen
The Statistical Diagnostic Screen displays information about how well data is being
received from the weather station to the console. The information that is displayed in
this screen includes:
Note: Several of these values, with a *, are used by Davis engineers.
1. Time of day or number of times the anemometer reed switch was seen closed
*
.
The reed switch closes once each revolution of the anemometer wind cups. Press
WIND to toggle between these two values.
2. Date or the number of times the anemometer reed switch was seen open
*
. Press
WIND to toggle between these two values.
Note: The time and date displays can be toggled in both statistical and reception diagnostic screens.
3. Number of packets containing “Cyclical Redundancy Check” (CRC) errors
received. The system runs a CRC check on data packets. Any data packets that
don’t pass this check are considered to contain errors and are discarded. These
are considered bad packets. This also includes the CRC errors received during
radio acquisition.
4. The firmware version currently installed on the console.
5. Maximum number of bad packets in a row without resynchronization.
6. Number of times the console resynchronized with the transmitter. The console
will attempt to resynchronize with the station after 20 consecutive bad packets.
7. Percentage of good packets received. Graph shows the current and last 25 days of
good packet percentage data. The vertical scale is fixed at 10% per dot.
8. The total number of bad data packets including missed packets and CRC errors.
Missed packets are described as when a data packet is expected, but is not
recognized as a data packet by the console. This does not include bad packets
received during acquisition.
9. Current streak of consecutive bad packets. The counter increments when the
console is synchronized but the packet is bad. This value is reset to zero when a
good packet is received.
10. Current streak of consecutive good packets received.
11. Station Number
12. Transmitter Domain
