SAVECONFIG COMMAND

If you change the configuration of a function and want to save
the new settings for your next session, use the SAVECONFIG
command.

CONFIGURING THE COMMUNICATION PORT

Use the COM command to configure the communication port
through the command line. For example, to set COM port 2 to
9600 bps, no parity, 8 data bits, 1 stop bit, no handshaking, echo
off, and break detection on, enter the following:

com com2 9600 n 8 1 n off on

NMEA LOGS

To configure the receiver output through the command line:

1. Ensure the communication port is configured:
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:

log gpgga ontime 0.5

ENABLING SBAS POSITIONING

To enable SBAS positioning, enter the following command:

sbascontrol enable

Once enabled, the Solution type field shown in the Connect
Position window changes from Single to SBAS, and you may
see SBAS satellites in the Constellation window. SMART-MR10
will track available SBAS satellites, including WAAS, EGNOS
and other SBAS systems.

ENABLING GL1DE

®

To enable

GL1DE, enter the following commands:

pdpfilter enable

pdpmode relative auto

ENABLING Bluetooth WIRELESS TECHNOLOGY

Bluetooth wireless technology is configured on the SMART-AG
COM3 internal port and is enabled by default.

To disable Bluetooth wireless technology:

btcontrol disable

To enable Bluetooth wireless technology:

btcontrol enable

For detailed information about the configuration and enabling of
Bluetooth wireless technology on the SMART-AG, refer to
Chapter 5 Bluetooth Configuration in SMART-AG User Manual.

USING THE CAN BUS

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 on Page 1.

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
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.

The CAN module is generally not user-interactive.It is activated
by entering the command SETCANNAME 305. If this is followed

by entering the SAVECONFIG command, the CAN module is

activated immediately on all subsequent start-ups. The module
supports NMEA2000 Parameter Group Message (PGN): PGN
129029 GNSSPositionData, PGN 129025
GNSSPositionRapidUpdate, and PGN 129026
COGandSOGRapidUpdate.

EMULATED RADAR (ER)

The SMART-AG provides an emulated ground speed RADAR
pulse output. The enclosure outputs ER via the bare wires
labeled ER GND and ER_OUT on the SMART-AG cable. See
Table on Page 1 for the pin-out details of this cable. Also see
Appendix B.5 RADARCFG of the SMART-AG User Manual.

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.

TERRAIN COMPENSATION

The optional 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
.

For proper operation, SMART-AG requires proper installation,
accurate height setting and levelling of the tilt sensor.

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 or COM2) 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.

To log data, use the LOG command. For example, to log the

pseudorange position to COM 2 every 30 seconds, enter the
following:

LOG COM2 PSRPOS ONTIME 30

When requesting logs, you can request the output data in three
formats:

ASCII

Abbreviated ASCII

Binary

Abbreviated ASCII is the best format to use when you want to
work with the receiver directly and review individual log contents
visually.

When using Connect to configure your receiver, ensure all
of the graphical windows are closed before you issue the
SAVECONFIG command.
