* The HR2 receiver has two methods of decoding PPM transmissions. PPM transmissions may be
decoded by one or both decoders; in either case, a single detection is reported in the DET record.
Ping and detection counts are separated by decoder in the DIAG_HR2 record to allow accurate
calculation of ping: detection ratios for system troubleshooting purposes.
DIAG_VR2W
DIAG_VR2W records contain daily VR2W diagnostic (ping and detection count) information. They
are generated every 24 hours at midnight (UTC).
Field
Description
Device Time (UTC)
UTC date and time of the data according to the receiver’s clock (the
uncorrected time).
Time
Date and time of the data following correction for receiver clock drift
(the
corrected
time). The time offset of this time from UTC is indicated
in the “Time Offset (h)” column.
Time Offset (h)
Offset from UTC time, in hours, of the value in the “Time” column. The
time offset is as selected when the receiver log was exported to Fathom
CSV format using the Fathom software.
Time Correction (s)
The difference between uncorrected (“Device Time (UTC)”) and cor-
rected (“Time”) times.
Model
Receiver model that generated the data in this record.
Serial Number
Serial number of the receiver that generated the data in this record.
Pings
Number of pings recorded in the previous 24 hours
Detections
Number of detections recorded in the previous 24 hours
