2. Filtering of messages (FILTER, PRINT, TYPE, ADD and REMOVE commands)
The Device has eight filter lists, which allows limiting the set of messages passed from the NMEA 2000
network to a PC application (incoming has RX suffix) and messages passed from the PC application
to NMEA 2000 network (outgoing, has TX suffix):
• global_rx - Global filter for incoming NMEA 2000 messages transmitted to PC
• global_tx - Global filter for messages transmitted to NMEA 2000 network from PC
• raw_rx - For incoming messages transmitted to PC in RAW mode
• raw_tx - For messages received from PC in RAW mode
• n2k_rx - For messages transmitted to application in N2K mode
• n2k_tx - For messages received from application in N2K mode
• 0183_rx - NMEA 0183 sentences passed to application in 0183 mode
• 0183_tx – NMEA 0183 sentences accepted from application in 0183 mode
For operation with filter lists, you should be familiar with NMEA 2000 and NMEA 0183. Otherwise,
we recommend not modifying any filters and using the filter setting in the PC application. In case of troubles
with filters, you can reset the list of filters to the factory settings using the command RESET FILTERS
or RESET SETTINGS, which resets all settings including filters.
To view or modify the filter, you should “activate” (select) it with the FILTER command first. For example:
FILTER GLOBAL_RX
The PRINT command without parameters prints records of the active filter. To view a non-active filter,
specify its name after the command:
PRINT GLOBAL_TX
