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
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

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

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
