Vemco HR2, User Manual

Page: 131 / 212

* 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).
