NMEA2000 logging

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7

OEM7 receivers support both a subset of the standard NMEA2000 PGNs, as well as NovAtel proprietary PGNs.

All NMEA2000 logs are configured using the LOG command, where the COM port is a CAN port (CCOM). The CCOM port must be associated with a J1939 node using the CCOMCONFIG command. If only NMEA2000 logs are needed, CCOMCONFIG parameters other than J1939NODE may be ignored.

To enable NMEA2000 logs:

  1. Configure the CAN bus. See Configuring the CAN bus.

  2. Enable the CCOM port on the CAN bus node using the CCOMCONFIG command.

  3. Enable the desired NMEA2000 logs.

NMEA2000 logs can be requested regardless of the on/off bus status of the receiver or the J1939 configuration. They are output if and only if the receiver is online.

The position for the PGN129025, PGN129027 and PGN129029 logs are reported in the user selected datum. See the OUTPUTDATUM command for more details.

When the solution type is INS (SPAN models), the DOPs in the PGN129029 message are calculated at a 1 Hz rate.

To determine if the receiver is providing an INS solution, check the pos type field in the BESTPOS log.

Example of NMEA2000 log configuration

  1. CCOMCONFIG CCOM1 NODE1 NMEA2000

  2. LOG CCOM1 PGN129025 ONTIME 0.5

  3. LOG CCOM1 PGN129026 ONTIME 0.25
