2.2Additional Features and Information
This section contains information on the additional features of the SMART6, which may affect the overall
design of the receiver system.
2.2.1Status Indicators
LED indicators on the SMART6 provide the status of the receiver. The table below shows the meaning of the
LEDs.
Table 3: SMART6 LED Status Indicators

OnFlashingOffTracking at least one satellite but not a valid position.
OnOnOffPosition valid in basic autonomous mode.
OnOnFlashingSBAS tracking, but not enough data for enhanced solution.
OnOnOnPosition valid in an enhanced accuracy mode
Troubleshooting:
•If the power is on but the yellow LED does not flash within one minute, then no satellites are being
tracked. There may be excessive blockage or the SMART6 may be defective. Make sure the SMART6
has an unobstructed view of the sky. Try power cycling the SMART6.
•If the yellow LED is flashing but doesn’t progress to solid yellow within one minute, then insufficient
satellites are being tracked or the signal quality is poor and ephemeris data cannot be received.
Normally, four satellites are sufficient for a valid position as long as they are widely distributed in the sky.
If LED is stuck on blinking yellow, there may be excessive signal blockage or the SMART6 may be
defective. Make sure the SMART6 has an unobstructed view of the sky. Try power cycling the SMART6.
•If the yellow LED is on, but the green doesn’t turn on within five minutes than no SBAS or DGPS
positions are available. If you are using SBAS, make sure SBAS is available in your area and that the
SMART6 is configured to enable SBAS positions (SBASCONTROL ENABLE). For DGPS, make sure the
SMART6 is configured with the correct serial port parameters and to accept the DGPS protocol your area
is using and that your data modem is connected and working.
•The green LED blinks when SBAS is detected then it comes on solid when SBAS is enabled. The LED
will stay dark if SBAS is not detected.

SMART6 User Manual Rev 317
Installation and SetupChapter 2
2.2.3Emulated Radar (ER)
The SMART6 outputs an emulated RADAR signal via the bare wires labeled ER GND and ER_OUT on the
SMART6 cable. See Table 5, SMART6 Communication/Power Cable Pin-outs on page 56 for the pin-out
details of this cable.
The ER outputs a logic high of supply voltage minus 0.5 V minimum and logic low of 0.5 V maximum with a
rise and fall time of less than 1 ms. Its output references signal GND and provides logic low output until its
speed is greater than 1 km/Hr. ER can be configured to operate at one of three distinct frequencies (26.11,
28.12 or 36.11 Hz/km/Hr, with 26.11 Hz/km/Hr being the default value) and with an effective range from 1 km/
Hr to 55 km/Hr for near-horizontal applications. See Section B.7, RADARCFG Configure the ER Output on
page 67 for more information.
2.2.4Controller Area Network (CAN)
The SMART6 supports the following NMEA2000 Parameter Group Messages (PGN):
•PGN 129029 GNSSPositionData (1 Hz)
•PGN 129025 GNSSPositionRapidUpdate (10 Hz)
•PGN 129026 COGandSOGRapidUpdate (10 Hz)
The CAN must be activated by entering the SETCANNAME command (refer to B.9
SETCANNAME Sets the CAN name fields on page 70). To have the CAN set up automatically
at subsequent start ups, also send the SAVECONFIG command.

of vehicle
The SMART6 must be rigidly secured to the vehicle to minimize errors due to vibration and
motion.
2.2.5.2 Height Measurement and Configuration
The height measurement should be made while the vehicle has the correct tire pressure and is parked on a
hard-packed and level surface. The measurement should be made from the ground to the bottom of the
SMART6 connector. The measurement accuracy should be within 1 to 2 inches (2.5 to 5.0 cm).
Once the measurement has been made (in feet and inches, or metres), refer to Section B.6, $PMDT Configure Tilt Compensation on page 66 for instructions on how to set the height in the SMART6.
The height must be saved after the height command is sent. This must be done so the height data is saved
between power cycles. Instructions on sending the save command are outlined in Section B.6, $PMDT Configure Tilt Compensation on page 66.
Note that changes in tire pressure over time can potentially cause errors in tilt compensation. This is because
the height of vehicle can vary with tire pressure.
The SMART6 is shipped from the factory with the height set to 0.0 metres.

2.2.5.3 Leveling the Tilt Sensor
The vehicle must be parked on flat ground when the level command is sent to the SMART6. Refer to
Section B.6, $PMDT Configure Tilt Compensation on page 66 for instructions on how to send the level
command.
After the tilt sensor has been leveled, the data must be saved to non-volatile memory using the save
command. Instructions on using the save command are outlined in Section B.6, $PMDT Configure Tilt Compensation on page 66.
SMART6 User Manual Rev 320
Chapter 3Operation
Before operating the SMART6 for the first time, ensure the installation instructions in Chapter 2, Installation
and Setup were followed. It is assumed that a computer is used during initial operation and testing for greater
ease and versatility.
3.1Communications with the Receiver
Communication with the receiver typically consists of issuing commands through the communication ports
from an external serial communications device. This could be either a terminal or computer connected
directly to the receiver serial port using a DB-9 connector on the SMART6 communication/power cable. If
using a radio, connect it to another DB-9 connector on the same communication/power cable by means of
the radio serial cable supplied with the radio. It is recommended that you become thoroughly familiar with the
commands and logs detailed in the OEM6 Family Firmware Reference Manual to ensure maximum utilization
of the receiver’s capabilities.
3.1.1Serial Port Default Settings
The receiver communicates with the computer or terminal via an RS-232 serial port. For communication to
occur, both the receiver and the operator interface have to be configured properly. The receiver’s COM1 and
COM2 default port settings are:
•9600 bps, no parity, 8 data bits, 1 stop bit, no handshaking, echo off
The receiver’s AUX default port settings are:
•9600 bps, no parity, 8 data bits, 1 stop bit, no handshaking, echo off
To change the default settings, use the SERIALCONFIG command. See Appendix B.8, SERIALCONFIG Configures serial port settings starting on Page 68 for details.
The data transfer rate chosen determines how fast information is transmitted. For example, outputting a log
whose message byte count is 96. The default port settings allows 10 bits/byte (8 data bits + 1 stop bit + 1
framing bit). It therefore takes 960 bits per message. To get 10 messages per second, 9600 bps is required.
Also remember that even if the bps is set to 9600, the actual data transfer rate is lower and depends on the
number of satellites being tracked, data filters in use and idle time. It is suggested a margin is set when
choosing a data rate (115200 is recommended for most applications).
Although the receiver can operate at data transfer rates as low as 300 bps, this is not desirable.
For example, if several data logs are active (that is, a significant amount of information needs to
be transmitted every second) but the bit rate is set too low, data will overflow the serial port
buffers, causing a warning in the receiver status and loss of data.
3.1.2Communicating Using a Remote Terminal
One method of communicating with the receiver is through a remote terminal. The receiver is pre-wired to
allow proper RS-232 interface with the data terminal. To communicate with the terminal, the receiver only
requires the RX, TX and GND lines to be used. Request to Send (RTS)/Clear to Send (CTS) hardware
handshaking is not available. Ensure the terminal’s communications set up matches the receiver’s RS-232
protocol.
3.1.3Communicating Using a Computer
A computer can be set up to emulate a remote terminal as well as provide the added flexibility of creating
multiple command batch files and data logging storage files. Any standard communications software
package, that emulates a terminal, can be used to establish bidirectional communications with the receiver.
For example, HyperTerminal or NovAtel’s Graphical User Interface (GUI) program NovAtel Connect™. All
data is sent as raw 8-bit binary or ASCII characters.

connecting to the receiver and requesting the RXSTATUS log. Refer to the OEM6 Family Firmware
Reference manual for details.
If a persistent error develops, contact your local NovAtel dealer first. If the problem remains unresolved,
contact NovAtel directly through any of the methods listed in the Customer Service section on page 9.
3.2.2Communicating with the Receiver Using NovAtel Connect
NovAtel Connect is a Windows based GUI used to access the receiver's many features. Convert is a utility
that converts between file formats and strips unwanted records for data file compilation. Both are included in
the NovAtel Connect PC Utilities bundle available from: www.novatel.com/support/search/items/
PC%20Software.
Launch the NovAtel Connect program and select Device | Open Connect from its main menu. The Open Connection window appears.
Figure 8: Open Connection Window
Refer to the NovAtel Connect help file or press F1 while the cursor is in a NovAtel Connect window. Ensure
the Console and ASCII Messages windows are open by selecting them from the View menu.
When the receiver is first turned on, no data is transmitted from the COM ports except for the port prompt.
The console window displays a port name:
[COM1] if connected to COM1 port
[COM2] if connected to COM2 port
[AUX] if connected to AUX port or through Bluetooth
Any of the above prompts indicate the receiver is ready and waiting for command input.
1. You may also have to wait for output from receiver self-tests. For example, on start-up, the
SMART6 User Manual Rev 322
SMART6 is set to log the RXSTATUSEVENTA log ONNEW on all ports. Refer to the OEM6
Family Firmware Reference Manual for more details.
2. If NovAtel Connect is unable to locate the SMART6, try using a different COM port to
communicate to the receiver. Once communication has been established, issue the FRESET STANDARD command. You should now be able to use the original communication port again.
3. When using the AUX port, you must use a “Passive” connection in NovAtel Connect.
OperationChapter 3
Commands are typed at the interfacing computing device’s keypad and executed after issuing a carriage
return command which is usually the same as pressing the <Enter> key.
An example of a response to an input command is the FIX POSITION command. It can be as:
[COM2] FIX POSITION 51.11635 -114.0383 1048.2 [Carriage Return]
<OK
where [COM2] is the port prompt, followed by the command entered and [Carriage Return] is a prompt to
press the <Enter> key.
The example above illustrates the command input to the base receiver’s COM2 port, which sets the position
of the base station receiver for differential operation. Confirmation that the command was actually accepted is
the appearance of <OK.
If a command is entered incorrectly, the receiver responds with:
<Invalid Message ID (or a more detailed message)
Ensure the computer’s Control Panel Power Settings are not set to Hibernate or Standby
modes. Data is lost if one of these modes occurs during a logging session.
3.3Transmitting and Receiving Corrections
RTK or DGPS corrections can be transmitted from a base station to a rover station to improve position
accuracy. The base station is the GNSS receiver, which is acting as the stationary reference. It has a known
position and transmits correction messages to the rover station. The rover station is the GNSS receiver which
does not know its exact position and can be sent correction messages from a base station to calculate
differential GNSS positions. The SMART6 can be used as a base receiver to transmit RTK or DGPS
corrections or a rover to receive the same corrections. An example of a differential setup is given in Figure 9, Basic Differential Setup on page 24.

The configuration shown in Figure 9, Basic Differential Setup is valid for SMART6 receivers
System biases can introduce errors, refer to our GNSS Book found on our Web site at www.novatel.com/an-
introduction-to-gnss/ for more information. In most cases, a data link between the base station and rover
station (two NovAtel receivers) is required to receive corrections. SBAS corrections can be accomplished
with one receiver and are exceptions to the base/rover concept. Generally, a link capable of data throughput
at a rate of 9600 bits per second and less than 4.0 s latency is recommended.
Once the base and rover are set up, configure them as shown in the configuration examples that follow in
Section 3.3.1, Base Station Configuration on page 25 and Section 3.3.2, Rover Station Configuration on
page 26.
without optional Bluetooth.
For a SMART6 receiver with Bluetooth, two of the serial devices connect through COM1 and
COM2 and the other device must connect through Bluetooth.
