Diagnostics
The NMEA 2000 tab on the diagnostics page can provide information useful for identifying an
issue with the network.
Bus state simply indicates whether the bus is powered, but not necessarily connected to any
data sources. However if bus shows as ‘off ’, but power is present along with an increasing error
count, it is possible that termination or cable topology is incorrect.
Rx Overfl ows: The CAN driver got too many messages for its buff er before the application
could read them.
Rx Overruns: The CAN hardware got too many messages for its buff er before the CAN driver
could read them.
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 missed frame, or
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.

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).
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.
Radar setup
Setup and confi guration of the Broadband radar has been simplifi ed compared to traditional
pulse radars. There is no zero range (time delay), no warm up time, and no burn-in required..
Radar source
In a system with more than one radar, the correct device to confi gure can be selected from
this menu.

Note: some radar like the broacband 4G support dual radar mode, and therefore are repre-
sented twice in the source list, with an A and B suffi x.
