SETUP OF INPUTS AND OUTPUTS
The system will allow many NMEA formats to be displayed:
VMVBW Speed long, trans, forward water speed
VMMTW Temperature (water)
VMVLW Trip/Total (distance sailed)
VMVHW Speed through water (resultant)
DIAG Diagnostic output (all others deactivited)
VMXDR Vessel (sensor) direction (CD401EB only)
VMALR Alarm messages
Denitions of sentences are available in “Appendix 3”
on page 56.
The system will automatically update recognised
formats. If the user wishes to output NMEA, the user
can select the NMEA sub menu in the SETUP menu and
move to the different formats using the up (↑) and down
(↓) buttons. Each format can be activated/deactivated
using the SET button.
AVERAGING
Each speed log type has some lters to ensure stable
and correct data. The averaging lter takes a number
of measurement pulses and makes a rolling average of
these values. The longer the averaging is, more stable
the data will be. However, the slower the system will
respond to changes.
The Compact speed logs have a minimum value of
10 seconds. If the system seems unstable at times, increasing the average
time will reduce the uctuations. However, the ltering is time based and as it
increases, the response time of the system will decrease.
