Novatel GPS Receiver SMART AG User Manual

The cable has two DB-9 connectors, see Figure 1. One  
can accommodate a PC/laptop serial (RS-232)  
communication port and the other can connect to a  
modem or radio transmitter to receive differential  
corrections (refer to your user-supplied modem or radio  
transmitter information for its connectors).  
2. Connect the SMART-AG to a DB-9 serial port on the PC.

information you need to set up and begin  
using your new SMART-AG, a combined  
L1 GNSS receiver and antenna with  
Emulated Radar (ER) output. For more  
detailed information on the installation  
and operation of your receiver, please  
refer to the SMART-AG and OEMV user manuals, which can be  
found on our website at  
At the other end is a 14-pin connector, see Figure 1. In  
addition, there are a number of bare wires where the  
outer insulation is cut away but the wires beneath are  
intact. See Table 1 below for their pinouts. This cable is  
RoHS compliant and its part number is 01018256.

3. Connect power to the SMART-AG. The cable’s red wire  
(connector pin 14) is to be connected to the positive side of a  
12 or 24V vehicular power circuit (or equivalent) protected  
by a 5A fast blow fuse (user supplied). The cable’s black  
wire (connector pin 9) is to be connected to the negative side  
of the power circuit. If a SMART-AG cable (NovAtel part  
number 01018256) is not used, a minimum wire size of  
0.5 mm/ 20AWG must be used.

ENTERING COMMANDS  
ENABLING SBAS POSITIONING  
The SMART-AG uses a comprehensive command interface.  
Commands can be sent to the receiver using the Console  
window in CDU, which is opened from the View menu. Enter  
commands in the text box at the bottom of the Console window.  
To enable SBAS positioning, enter the following command:  
Logs can be generated in one of three formats: ASCII,  
Abbreviated ASCII, or Binary. Refer to the OEMV Family  
Firmware Reference Manual (OM-20000094) for information on  
the LOGcommand, specifying the output format, and the  
detailed contents of each log.  
EMULATED RADAR (ER)  
sbascontrol enable  
The SMART-AG outputs an emulated RADAR signal. The  
enclosure outputs ER via the bare wires labeled ER GND and  
ER_OUT on the SMART-AG cable. See Table 1 on Page 1 for  
the pin-out details of this cable. Also see Appendix B.5  
RADARCFG of the SMART-AG User Manual.  
To enable GL1DE, enter the following commands:  
pdpfilter enable  
If you prefer, CDU provides a graphical interface for configuring  
data logging. Select Logging Control Window from the Tools  
menu. In the Logging Control window, you can select which logs  
to capture and choose to which ports to send the data. In  
addition, you can specify a file in which to save the data.  
pdpmode relative auto  
USING THE CAN BUS  
The ER outputs a logic high of 6.3 V minimum and logic low of  
1.5 V maximum with a rise and fall time of less than 1 ms. Its  
output references battery GND when output is logic low and  
provides logic low output until its speed is greater than 1 km/Hr.  
It provides an output frequency that represents 26.11 Hz/km/Hr  
with an effective range from 1 km/Hr to 55 km/Hr and uses 2D  
velocity for near-horizontal applications.  
The following information is important when entering commands:  
A CAN Bus is a serial bus that provides services for processes,  
data and network management. There is CAN Bus capability  
through the SMART-AG cable, see Table 1 on Page 1. CAN Bus  
functionality is controlled through NovAtel’s optional API  
software available through Customer Service. The API header  
file (*.h), in the API folder after installation, includes  
Commands can be entered in three formats:  
ASCII (log bestposa)  
Abbreviated ASCII (log bestpos)  
Binary (log bestposb).  
Abbreviated ASCII is the best format to use when you  
wish to work with the receiver directly. For data  
collection, use ASCII or Binary.  
documentation on using the CAN Bus.  
TERRAIN COMPENSATION  
NMEA 2000 is a CAN standard created by the National Marine  
Electronics Association and designed to support networking in  
marine applications. It functions over a longer physical distance,  
and supports more physical nodes than ISO 11783. The  
relationship between NMEA2000 and SAE J1939 is that J1939  
is the standard,while the NMEA 2000 group has added some  
new messages (called PGNs or Parameter Group Numbers)  
and added a new, additional transport protocol called  
The SMART-AG Terrain Compensation feature corrects for  
errors in position caused by rolling of the vehicle. The SMART-  
AG senses the vehicle’s roll angle and, with the user-entered  
“height above ground”, compensates the position output to give  
the position under the vehicle rather than at the antenna. Once  
configured, corrected positions are sent to host equipment. See  
the Appendix B.4 $PMDT of the SMART-AG User Manual.  
Press Enter to send the command string to the receiver.  
The commands are not case sensitive.  
When logging data through CDU, close all unused graphical  
windows to save COM port throughput and receiver CPU usage.  
The OEMV Family Quick Reference Guide provided with the  
receiver lists the available commands and the parameters they  
use for the Abbreviated ASCII format.  
NMEA LOGS  
FastPacket. NMEA2000 compliant, for all intents and purposes,  
means J1939 compliant plus support for new NMEA2000  
messages. In other word, one cannot have NMEA2000 without  
J1939 support as well. J1939 is additionally “harmonized” with  
ISO 11783, a standard for the agriculture industry.  
For proper operation, SMART-AG requires proper installation,  
accurate height setting and levelling of the tilt sensor.  
To configure the receiver output through the command line:  
LOGGING DATA  
An extensive collection of logs has been created to capture the  
data your SMART-AG receives and processes. These logs can  
be directed to a SMART-AG port (COM1, COM2 or USB) and  
can be automatically generated when new or changed data  
becomes available or at regular intervals. The available logs are  
listed in the OEMV Family Quick Reference Guide.  
1. Configure the communication port using the COM  
command. For example, to set COM port 2 to 9600 bps, no  
parity, 8 data bits, 1 stop bit, no handshaking, echo off, and  
break on, enter the following:  
The CAN module is generally not user-interactive. It is activated  
when a SETCANNAME command is entered, and after a  
SAVECONFIG, the CAN module is activated immediately on all  
subsequent start-ups. The module supports NMEA2000  
Parameter Group Message (PGN): PGN 129029  
com com2 9600 n 8 1 n off on  
2. Select and configure the NMEA string that you want to  
output. For example, to log gpgga (position system fix data  
and undulation) at 2 Hz, enter the following:  
To log data, use the LOGcommand. For example, to log the  
pseudorange position to COM 2 every 30 seconds, enter the  
following:  
log gpgga ontime 0.5
