
Flashing means that the LED is turning on and off at a 1 Hz rate - 0.5 seconds on and 0.5
seconds off.
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 AG-STAR may be defective. Make sure the AG-STAR
has an unobstructed view of the sky. Try power cycling the AG-STAR.
•
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 AG-STAR may be
defective. Make sure the AG-STAR has an unobstructed view of the sky. Try power cycling the AG-STAR.
•
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
AG-STAR is configured to enable SBAS positions (SBASCONTROL ENABLE). For DGPS, make sure
the AG-STAR 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.

MKI and PPS Strobes
The Mark Input (MKI) and Pulse Per Second (PPS) strobes provide status and synchronization signals. PPS
is a 3.3V CMOS output; MKI is a 5V logic tolerant input.
Pin-out information can be found in Table 4, AG-STAR Communication/Power Cable Pinouts on page 45.
2.2.3
Emulated Radar (ER)
The AG-STAR outputs an emulated RADAR signal via the bare wires labeled ER GND and ER_OUT on the
AG-STAR cable. See Table 4, AG-STAR Communication/Power Cable Pinouts on page 45 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.5, RADARCFG Configure the ER Output on
page 54 for more information.

Chapter 3
Operation
Before operating the AG-STAR for the first time, ensure that you have followed the installation instructions in
Chapter 2, Installation and Setup on page 12. It is assumed that a computer is used during initial operation
and testing for greater ease and versatility.
3.1
Communications 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 that is directly
connected to the receiver serial port using a DB-9 connector on the AG-STAR multi-cable. If you are using a
radio, it connects to another DB-9 connector on the same multi-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 OEMStar Firmware Reference Manual (OM-20000127) to ensure maximum utilization of the
receiver’s capabilities.

3.1.1
When power is applied to the AG-STAR, the Power LED lights and the AG-STAR begins a self
test and the boot up process. After the self test and boot up have completed, the command
prompt becomes available on the serial port.
Serial Port Default Settings
The receiver communicates with your computer or terminal via an RS-232 serial port. For communication to
occur, both the receiver and the computer or terminal have to be configured properly. The receiver’s COM1
and COM2 default port settings are as follows:
•
9600 bps, no parity, 8 data bits, 1 stop bit, no handshaking, echo off
Changing the default settings requires using the COM command. See Section B.2, COM
Port on page 48 for details.
Configure COM
The data transfer rate you choose 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 then requires 9600 bps.
Also remember that even if you set the bps 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 that you leave yourself a
margin when choosing a data rate (115200 is recommended for most applications).

3.1.2
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 an error condition in the receiver status and loss of data.
Communicating 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 a 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.

Operation
3.1.3
Chapter 3
Communicating 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 Graphic User Interface (GUI) program NovAtel Connect. All data is
sent as raw 8-bit binary or ASCII characters.
3.2
Getting Started
3.2.1
Starting the Receiver
When first powered, the AG-STAR undergoes a complete self-test. The results of this test can be viewed by
connecting to the receiver and requesting the RXSTATUS log. Refer to the OEMStar Firmware Reference
Manual (OM-20000127) for more information.
If a persistent error develops, contact your local NovAtel dealer first. If the problem is still unresolved, contact
NovAtel directly through any of the methods listed in Customer Support on page 9.
3.2.2
Communicating with the Receiver Using NovAtel Connect
NovAtel Connect is a Windows-based GUI used to access the receiver's many features. The Convert utility is
a Windows-based 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/firmware-software-and-manuals/firmware-software-updates/.
Launch the NovAtel Connect program and select Device | Open from its main menu. The Open Configuration
window appears.
Figure 7: Open Configuration Window
Refer to the NovAtel Connect help file by selecting the Help | Contents menu or pressing 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
or
[COM2]
if connected to COM2 port or through Bluetooth

Operation
Chapter 3
Any of these prompts indicate that 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
AG-STAR receiver is set to log the RXSTATUSEVENTA log ONNEW on all ports. Refer to
the OEMStar Firmware Reference Manual (OM-20000127) for more details.
2. If you find that NovAtel Connect is unable to locate your AG-STAR receiver, try using a
different COM port to communicate to the receiver. Once communication has been
established, issue the command FRESET STANDARD. You should now be able to use your
original communication port again.
Commands are typed at the interfacing computing device’s keyboard and executed after issuing a carriage
return command which is usually the same as pressing the  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]
 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 "
6. Send the SOFTLOADCOMMIT command.
7. During the loading process, SOFTLOADSTATUSA logs report the load status. Wait for the
SOFTLOADSTATUSA to indicate loading is COMPLETE.
8. Send the new auth-code for the receiver with the following special case of the AUTH command:
AUTH ADD_DOWNLOAD 
9. Reset the receiver by entering RESET, FRESET or power cycling.
10. Once the receiver resets, the new version of firmware is active.

5.4.1
The SoftLoad process can be cancelled safely at any time during the process using the RESET
command.
Working with S-Records
•
Records beginning with S0, S5 and S7 should be passed to the receiver directly using the
SOFTLOADSREC command. These records contain meta data about the firmware image.
•
Records beginning with S3 form the actual firmware image and can be converted to SOFTLOADDATA
binary commands. Aside from the header, each pair of characters forms the ASCII representation of
binary byte. The format is as follows:
S3
LL
AAAAAAAA
DDDDDDDD...DDDDDDDD
CC
Check Sum. One's compliment of all other
bytes
Little Endian Data. These bytes are copied into the "data" field of the
SOFTLOADDATA command
4 - Byte Address. Set this as the value of "offset" in the SOFTLOADDATA command
Length. This is the hexadecimal number of character pairs to follow in the record. This value minus
4 bytes for the address and 1 byte for the check sum is copied into the "data length" field of the
SOFTLOADDATA command
Header
•
Multiple S3 records can be packaged into a single SOFTLOADDATA command as long as the data
from one S3 record follows immediately after the previous record, up to a maximum of 4096 bytes of
data. That is, the address must equal the previous address plus the previous data length. The "offset"
field remains the address of the first S3 record and the "data" and "data length" are updated to include
the new data.
•
The hex file data may contain many gaps and jumps. For example, in most NovAtel hex files data for
address 0x000_00000 is stored near the very end of the file.

Upgrading Using the AUTH Command
The AUTH command authorizes the enabling (unlocking) of model features. The AUTH command is used to
upgrade a new receiver model, available with the same firmware version as the current model. This
command only functions with a valid auth-code assigned by NovAtel Customer Support.
The upgrade can be performed directly through the NovAtel Connect command line or from any other
communications program.

5.5.1
Refer to Section 5.3.1.1, Types of Firmware Files on page 36 for details on updating versus
upgrading.
Upgrade Procedure
1. Power up the receiver and establish communications.
2. Issue the LOG VERSION command to verify the current model, firmware version and serial number
(refer to Section 5.2, Authorization Code on page 35 for instructions on obtaining).
3. Issue the AUTH command, followed by the auth-code and model type (refer to Section 5.2,
Authorization Code on page 35 for details on obtaining any auth-code). The syntax is as follows:
auth 
where auth is a command that enables model upgrades and auth-code is the upgrade authorization code,
expressed as follows:
XXXXXX,XXXXXX,XXXXXX,XXXXXX,XXXXXX,MODEL,EXPDATE
where:
1. Each X character is a case-insensitive ASCII character.
2. The MODEL string is a maximum of 15 characters long and represents the model enabled by the authcode.
3. The EXPDATE string is the auth-code’s expiry date, in YYMMDD format
Example:
auth 7WBMBK,887CB6,K5J3FH,5DF5P2,42PW8G,D1SB0GTT0,121211
When the AUTH command is executed, the receiver reboots. Issuing the LOG
confirms the new upgrade model type and firmware version number.

AG-STAR Communications/Power Cable (01018256)
The AG-STAR cable that accompanies the AG-STAR Development Kit, see Figure 28, AG-STAR
Communication/Power Cable, provides a means of supplying power from a battery while operating in the
field. The exposed wires (red for positive and black for negative) can then be connected to a vehicular power
circuit (or equivalent) protected by a 5A fast blow fuse (user supplied). The cable also has two DB-9
connectors. One can accommodate a computer serial (RS-232) communication port and the other can
connect to a modem or radio transmitter to propagate differential corrections (refer to your user-supplied
modem or radio transmitter user guide for more information on its connectors).

Bluetooth wireless technology uses the COM2 port. When Bluetooth wireless technology is
enabled, COM2 is not available on the AG-STAR connector or the cable.
In addition, there are a number of bare wires where the outer insulation is cut away but the wires beneath are
intact. See Table 4, AG-STAR Communication/Power Cable Pinouts on page 45 for their pinouts. For more
information on mating connectors and part numbers, see Table 5, AG-STAR Mating Connectors on page 46.

B.2
COM
Configure COM Port
This command permits you to configure the receiver’s asynchronous serial port communications drivers.
The current COM port configuration can be reset to its default state at any time by sending it two hardware
break signals of 250 milliseconds each, spaced by fifteen hundred milliseconds (1.5 seconds) with a pause of
at least 250 milliseconds following the second break. This will:
•
Stop the logging of data on the current port (see UNLOGALL command in the OEMStar Firmware
Reference Manual (OM-20000127)).
•
Clear the transmit and receive buffers on the current port.
•
Return the current port to its default settings (see Factory Defaults section in the OEMStar Firmware
Reference Manual (OM-20000127)).
•
Set the interface mode to NovAtel for both input and output (see INTERFACEMODE command in the
OEMStar Firmware Reference Manual (OM-20000127)).

Baud rates higher than 115,200 bps are not supported by standard computer hardware. Special
hardware may be required for higher rates, including 230400 bps, 460800 bps and 921600 bps.
Also, some computers have trouble with baud rates beyond 57600 bps.
Message ID:
Abbreviated ASCII Syntax:
COM [port] bps [parity[databits[stopbits[handshake[echo[break]]]]]]
Factory Default:
COM COM1 9600 N 8 1 N OFF ON
COM COM2 9600 N 8 1 N OFF ON

On AG-STAR receivers with Bluetooth wireless technology, the default settings for COM2 are:
com2 115200 n 8 1 cts off off
Changing the COM2 serial port settings could interfere with the ability to communicate using
Bluetooth wireless technology.
ASCII Example:
COM COM1,57600,N,8,1,N,OFF,ON

Use the COM command before using the INTERFACEMODE command on each port.

Watch for situations where the COM ports of two receivers are connected together and the
baud rates do not match. Data transmitted through a port operating at a slower baud rate may
be misinterpreted as break signals by the receiving port if it is operating at a higher baud rate.
This is because data transmitted at the lower baud rate is stretched relative to the higher baud
rate. In this case, configure the receiving port to have break detection disabled using the COM
command.

LOG
Request Logs from the Receiver
Many different types of data can be logged using several different methods of triggering the log events. Every
log element can be directed to any combination of the two COM ports. The ONTIME trigger option requires
the addition of the period parameter. See the OEMStar Firmware Reference Manual (OM-20000127) for
further information and a complete list of data log structures. The LOG command tables in this section show
the ASCII command format.
The optional parameter [hold] prevents a log from being removed when the UNLOGALL command, with its
defaults, is issued. To remove a log that was invoked using the [hold] parameter requires the specific use of
the UNLOG command. To remove all logs that have the [hold] parameter, use the UNLOGALL command with
the held field set to 1.
The [port] parameter is optional. If [port] is not specified, [port] is defaulted to the port that the command was
received on.

1. The OEMStar family of receivers can handle 30 logs at a time. If you attempt to log more
than 30 logs at a time, the receiver responds with an Insufficient Resources error.
2. Maximum flexibility for logging data is provided to the user by these logs. The user is
cautioned, however, to recognize that each log requested requires additional CPU time and
memory buffer space. Too many logs may result in lost data and degraded CPU
performance. Receiver overload can be monitored using the idle-time field and buffer
overload bits of the Receiver Status in any log header.
3. Polled log types do not allow fractional offsets or ONTIME rates faster than 1Hz.
4. Use the ONNEW trigger with the MARKTIME or MARKPOS logs.
5. Only the MARKPOS or MARKTIME logs, and ‘polled’ log types are generated ‘on the fly’ at
the exact time of the mark. Synchronous and asynchronous logs output the most recently
available data.
6. If you do use the ONTIME trigger with asynchronous logs, the time stamp in the log does
not necessarily represent the time the data was generated, but rather the time when the log
is being transmitted.

The above example shows BESTPOS logging to COM port 1 at 7 second intervals and offset by 0.5 seconds
(output at 0.5, 7.5, 14.5 seconds and so on). The [hold] parameter is set so that logging is not disrupted by
the UNLOGALL command.
To send a log only one time, the trigger option can be ignored.

1. In NovAtel Connect there are two ways to initiate data logging to the receiver's serial ports.
You can either enter the LOG command in the Console window, or use the interface provided in the Logging Control window. Ensure the Power Settings on your computer are not
set to go into Hibernate or Standby modes. Data is lost if one of these modes occurs during
a logging session.
2. Only the ASCII/Abbreviated ASCII log table is included in this manual. Refer to the LOG
command in the OEMStar Firmware Reference Manual (OM-20000127) for binary log
details.

NMEA Logs
The NMEA logs (receiver outputs) supported by the AG-STAR are summarized in the OEMStar Firmware
Reference Manual (OM-20000127). The available logs include:
•
GPGGA, which outputs a log of position system fix data and undulation. There are variants of
GPGGA, specifically:
•
GPGGALONG, which has both greater precision and the undulation field
GPVTG, which outputs track made good and ground speed
The steps for configuring the receiver output, through the command line are:
1. Configure the communication port using the COM command, described in Section B.2, COM
COM Port on page 48. To set COM port 2 as follows:
Bit Rate
9600
Parity
none
Data Bits
Stop Bits
Handshaking
None
Echo
Off
Break
On
Configure
enter the following string:
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 string:
log gpgga ontime 0.5
You can configure the log to output at various frequencies, as described in Section B.4, LOG
from the Receiver on page 51.
Request Logs
The above command line operations can also be carried out through NovAtel Connect. Information about
configuring the communication port can be found in the NovAtel Connect online help. The procedure for
adding a NMEA log through NovAtel Connect is summarized as follows:
1. In the Logging control window, click Logging to one or more of the receiver's serial ports. The Add Log
window displays.
2. Beside Select list, select Complete List or NMEA List.
3. Beside Log to file, select the NMEA log you want to add.
4. Select the port.
5. Configure the remaining fields then click Add.

NovAtel Position Logs
In addition to NMEA logs, NovAtel supports a range of non-NMEA position logs, described in the OEMStar
Firmware Reference Manual (OM-20000127), including:
•
BESTPOS: This log contains the best available position computed by the receiver, for example:
log bestposa ontime 0.5
•
BESTXYZ: This log contains the receiver’s best available position and velocity in ECEF coordinates,
for example:
log bestxyza ontime 1

Other Logs
The AG-STAR firmware generates the logs in Table 13, AG-STAR Logs in Alphabetical Order, in addition to
those of the OEMStar family log set. Refer to the OEMStar Firmware Reference Manual (OM-20000127),
