NMEA data sent to the CS system may contain a checksum.
When the CS system receives data with checksum included, it
will automatically calculate the checksum and compare this sum
with the checksum transmitted by the device.
When the calculated and the received checksum not are
identical, the settings in the Checksum tab in the System
Configuration dialog will decide whether the CS system will
use or reject these data.
Each serial line has its own checksum configuration. The
following selections are available:
No checksum will be calculated on the received data. The
only check will be whether the data is valid and within
logical limits.
Checksum will be used if available, but also data without
checksum will be used.
Only data with checksum will be used.
This is standard setting, and is recommended to be used.
Number of sequential checksum errors detected before a
checksum alarm will be given.
