Rx/Tx Errors
These two numbers increase when there are error messages, and decrease when messages
are received successfully. These (unlike the other values) are not a cumulative count. Under
normal operation these should be at 0. Values around 96 upwards indicate a heavily error
prone network. If these numbers go too high for a given device, it will automatically drop off
the bus.
Fast Packet Errors
Cumulative counter of any fast packet error. This could be a missed frame, or a frame out of
sequence etc. NMEA 2000 PGNs are made of up to 32 frames. The entire message will be
discarded when a frame is missed.
Ú
Note:
Rx and Tx Errors often indicate an issue with the physical network, which may be
resolved by correcting termination, reducing backbone or drop lengths, or reducing the
number of network nodes (devices).
Damping
If data appears erratic or too sensitive, damping may be applied to make the information
appear more stable. With damping set to off, the data is presented in raw form with no
damping applied.
Calibration
An offset (positive or negative) can be applied to correct inaccuracies in boat speed, sea
temp, air temp, barometric pressure, and depth sourced from NMEA 2000.
Ú
Note:
Any calibrations made here will ONLY be applied locally to this unit. Other devices
on the network will not have these offsets applied.
External Alarm Setup
The
Siren Enabled
option must be set in order for the unit to drive the buzzer when an
alarm condition arises. Its setting also determines the operation of the external alarm output.
Echosounder setup
Make general settings from the Echosounder Settings dialog. Define Echosounder sources in
the Installation dialog.
You can select which source is displayed in the Echosounder panel. You can also display two
different sources simultaneously, using a split panel configuration. All menu controls for each
panel are independent.
The source can be the internal Echosounder, another MFD on the Ethernet network, or a
Echosounder module.
Internal Echosounder
Select to make the internal Echosounder available for selection in the Echosounder menu.
For more information about panel source selection, refer to the Operator manual.
When set to off, this option disables the internal Echosounder in the unit. It will not be listed
as a Echosounder source for any unit on the network. Select this option on a unit which does
not have a transducer connected.
Network Echosounder
Enabling Network Echosounder allows the display to use other compatible Echosounder
sources on the Ethernet network as well as sharing it’s own Echosounder with other devices.
Structure depth offset
Setting for Structure transducers.
