CPT7 and CPT7700 Installation and Operation User Manual v12

To use CAN NOVATELBINARY, the CCOM port must be placed into NOVATELBINARY using the
INTERFACEMODE
command.
It is recommended to use one dedicated CCOM port for NovAtel messages and another dedicated
CCOM port for corrections.
NovAtel UI configuration does not affect NMEA2000. Any CCOM port can be used for NMEA2000
logs irrespective of CCOMCONFIG settings.
To configure NovAtel User Interface over CAN:
1. Configure the CAN Bus. See
2. Use the
CCOMCONFIG
command to configure the PGN and other CAN parameters.
3. Use the
INTERFACEMODE
command to configure the CCOM port for
NOVATELBINARY
.
Example: Configuring CCOM2 for NovAtel messages:
1.
CCOMCONFIG CCOM2 NODE1 1234 6 0x1C
2.
INTERFACEMODE CCOM2 NOVATELBINARY NOVATELBINARY OFF
8.6 Configuring OEM7 Receivers to Use OEM6 CAN Settings
CAN Bus functionality has been enhanced on OEM7 receivers. To accommodate the enhancements in
functionality and flexibility, several new commands and logs have been added. Also, the
SETCANNAME
command has been removed and the
CANCONFIG
command has been modified.
The following sections describes how to configure CAN on OEM7 receivers to operate like OEM6 receivers.
8.6.1 Configuration on OEM6
On OEM6 receivers, the
SETCANNAME
command, with minimal parameters, could be used to configure
CAN.
SETCANNAME 305
Once entered, a limited address claim procedure would take place and NMEA2000 logs would be generated
automatically at a fixed logging rate and fixed CAN port bit rate.
8.6.2 Configuration on OEM7
To configure an OEM7 receiver to log the same commands and use the same logging rate and CAN port bit
rate, enter the following commands:
CCOMCONFIG CCOM1 NODE1 NMEA2000
CANCONFIG CAN1 ON 250K
LOG CCOM1 PGN129025 ONTIME 0.1
LOG CCOM1 PGN129026 ONTIME 0.1
LOG CCOM1 PGN129027 ONTIME 0.1
LOG CCOM1 PGN129029 ONTIME 1.0
