1. Configure the CAN bus. See Configuring the CAN Bus on page 101.
2. Enable the CCOM port on the CAN bus node using the CCOMCONFIG command.
3. Optionally, specify a custom PGN for the OEM7 specific NMEA2000 logs using the
PGNCONFIG command.
4. 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.

RESET
It is strongly recommended to RESET the receiver after using the PGNCONFIG com-
mand. This prevents PGN ambiguities and conflicts.
6.4 Corrections Over CAN
All NovAtel supported correction types are supported over CAN ports (CCOM).
To send or receive corrections:
1. Configure the CAN Bus. See Configuring the CAN Bus on page 101.
2. Use the CCOMCONFIG command to configure the PGN and other CAN parameters used by
the RTK corrections CAN messages.
PGN : Use the PGN designated for corrections.
Address :
l
Use 0xFF to receive corrections from any CAN address and to broadcast corrections to
all CAN nodes.
l
Use 0x00 to 0xFE to send corrections to or receive corrections from a specific CAN node.
3. Use the
INTERFACEMODE command to configure the CCOM interface mode.
