once per two seconds. In the case of 38400 speed, the update rate will be 2 times per second.
Our recommendation is to set the highest possible speed. If you are sure that your equipment
does not require high speed, or you see CRC error signals from the LED (see Section V), you can decrease
the speed.
A speed above 38400 (57600, 115200) can be used for connection with PC adaptors or NMEA 0183
multiplexers with configurable port speed.
2. 0183_TX_TYPE=x, 0183_RX_TYPE=x, N2K_TX_TYPE=x and N2K_RX_TYPE=x
Where x – WHITE or BLACK
Factory configuration: BLACK
Defines the type of filter for messages transmitted to connected NMEA 0183 equipment (0183_TX_TYPE),
received from connected NMEA 0183 equipment (0183_RX_TYPE), transmitted to NMEA 2000 network
(N2K_TX_TYPE) and received from NMEA 2000 network (N2K_RX_TYPE).
See the next two parameters for details.
3. 0183_TX=x and 0183_RX=x
Where x – empty string or the list of 3-char NMEA 0183 sentence formatters separated by a comma.
Factory setting: empty string.
These settings define records of filter lists, used to process messages sent (0183_TX) and received
(0183_RX) from connected NMEA 0183 equipment.
According to the standard, a NMEA 0183 sentence starts with a $ or ! symbol, followed by a two-character
talker ID and a 3-char sentence formatter. These elements are followed by data fields (after the comma).
The sentence is finished by a check sum after the * (asterisk) symbol.
The Device uses 3-char sentence formatters only for filtering. The following sentences matches to GLL
and VDM records (sentence formatters):
