Chapter 5 ______________________________ Operating WMT700 with WS425 and SDI-12 profiles
VAISALA _______________________________________________________________________ 49
For example, a value of 99 signifies that all data samples were
determined to be valid and processed during the averaging time. If
some samples were determined to be "missing", these samples were
not processed and the reported signal quality is a proportional value
less than 99.
4. Bytes 28-29 are the modulo 256 hexadecimal checksum of the
ASCII values calculated for bytes from 2 to 27.
Example:

WS425 A/B NMEA Standard Profile
When the WS425 A/B NMEA Standard profile is configured, WMT700
sends messages based on the configured automatic message interval.
There are no operating commands available for the user.
Configurable Parameters
Table 14 on page 50 lists the configurable parameters and their allowed
and default values for the WS425 A/B NMEA Standard profile.
