2. Overview
The RV-M9 GPS transponder is a rugged high-speed UHF/VHF data modem with a built-
in 6-channel GPS receiver. It has ½ to 5 watts of RF power output, and operates as a
GPS transponder for tracking, and a radio modem for sending and receiving data.
As well as sending position and status, the RV-M9 also has a radio modem with
integrated Ethernet 10/100 Base-T interface.
For privacy and security, over-the air encryption is standard on every RV-M9 radio. For
radio network versatility, the RV-M9 incorporates a 16-bit identification code, allowing up
to 65,000 units to be identified in one system. For wide-area coverage, all RV-M9
transponders may be set to store-and-forward messages from other RV-M9
transponders.
2.1. Features
Transmissions include ID, position, speed, heading, voltage, temperature, input/output status, UTC time, and
proximity.
Ultra-fast 3mS TX-RX switching and 4-level GFSK modem allows truly “Real Time” tracking and status.
Outputs and accepts NMEA 0183 GLL, TLL, WPT, GSV, and PRAVE messages.
Built-in TDMA channel access allowing truly real-time tracking (200 transmission in 10 seconds)
Low power consumption.
16 bit addressing for up to 65,535 different unique IDs per channel.
10/100 Ethernet interface.
3. Operation
3.1. System Mode
The RV-M9 is generally configured in two different system modes; a Transmitter or a
Receiver. Transmitters may be either a PRIMARY and a SECONDARY.
The MODE command is used to read and set the System Mode. The table below shows
the default parameters that are configured when a unit’s MODE is programmed with the
MODE command.

Company Confidential 7Raveon Technologies Corp.
Any RV-M9 that is a TXRX may be either a PRIMARY or a SECONDARY. Primary
transmitters use TDMA slot 1 to transmit their GPS location in, and Secondary
transmitters use TDMA slot 2 to transmit their GPS locations in.
The second parameter of the MODE command is either a P or S for Primary or
Secondary. For example, to program a secondary transceiver, use the following
command:
MODE TXRX S
3.2. 10/100Base-T –TCP/IP Socket Connections
The RV-M9 user interface is provided via a 10/100Base-T Ethernet interface. All user
communications in and out of the unit use TCP/IP socket connections that are compatible
with Telnet client applications. By default, the RV-M9 is a TCP/IP Telnet server.
The RV-M9 can interact with up to five (3) Telnet connections (“sessions”) at any given
time –additional connection requests beyond this limit shall be rejected (terminated and
closed) by the RV-M9. By default, all connection attempts require successful completion
of a login authentication challenge sequence before an interactive session will be
established. The “Primary IP” address that the RV-M9is configured to use is set with the
IPADD xxx.xxx.xxx.xxx command.
There are three levels of radio modem access or session “roles” with corresponding
privileges and features; they are: “ADMIN”, “USER”, and “DATA”. Three programmable
User Name and Password (“credentials”) combinations are maintained within the RV-M9,
including one for each of the three roles defined above.The default credential settings
and their associated roles are as shown in the following table:
Default
Login Name

3.3. Roles
ADMIN The ADMIN role allows viewing and changing parameters within the unit,
but does not allow arbitrary over-the-air data transmission. Only one
ADMIN session is allowed at any given time.
USER The USER role allows viewing parameters within the unit, and querying
GPS position information; however, unit parameter values cannot be
changed. This role does not allow arbitrary over-the-air data
transmission.
DATA The DATA role allows exchange of arbitrary data over-the-air. This role
does not allow either viewing or changing parameters within the unit.
3.4. Login Authentication
The unit will respond to each of up to five coincident telnet connection requests with the
following authentication challenge prompt:
Enter Login Name:
The client must enter the Login Name followed by a <return>. The unit will then respond
with:
Enter Password:
The client must enter the password followed by a <return>.
where X.X is the firmware version and xxx.xxx.xxx.xxx is the quad-dotted-decimal IP
address of the unit.
After three failed attempts to enter a correct username/password combination, the session
will be terminated.
3.5. Session Modes
The RV-M9 ‘s Ethernet interface supports different Session Modes per connection:
Command Mode and Data Mode. The mode of any given connected telnet session is
determined by the role associated with the credentials (User Name and Password) that
were entered at the session start. Sessions authenticated with either the ADMIN or USER
credentials shall operate in Command Mode, whereas session authenticated with DATA
credentials shall operate in Data Mode.
When a given RV-M9 telnet session is in Data Mode, it will not accept user-commands. It
will output over-the-air data or GPS information whenever the unit receives it. Arbitrary
data may also be scheduled for transmission over-the-air by simply entering it via a telnet
session operating in this mode.
3.6. System Recovery
IF user forgets login credentials or IP information, there is a system in place to reset the
radio login information. Here’s how it works:

Company Confidential 9Raveon Technologies Corp.
If the radio is quickly reset (within 10seconds of turning it on) the “System
Recovery IP address” is initiated upon next startup.
If System Recovery is initiated upon a restart, the recovery IP address
192.168.26.4 is active for 30 seconds.
If user logs in with this recovery IP then he or she will be prompted to reset to
defaults, to which they could type ‘Y’ to erase as prompted.
If a telnet session is initiated on the System Recovery IP address, the unit will immediately
revert back to factory defaults. The passwords and login text will be changed back to the
defaults, the primary IP address will revert back to factory default, and the frequency will
be changed back to factory default.
Caution: Do not attempt to login to the System Recovery IP address unless you want to
erase all settings within the unit.
After the unit has been running more than 30 seconds, the System Recovery IP address
is disabled.

4. Electrical Inputs and Outputs
The front panel of the RV-M9 modem has these features:
1. Power LED (red blink = on, green blink = telenet connected)
2. Status LED (Receive data = green, Transmit = red)
3. GPSLED (off = failed/no GPS, red = locking, green = locked)
4. Ethernet connector
5. Ethernet jack cover
4.1. LEDs
The LED’s visually show the current status of the radio.
Power LED (PWR) The state of this LED is usually solid green, showing power is on.
When a user logs in, the light will flash green with a 50% duty cycle.
Status LED (TX) This LED blinks red when the transmitter keys and is putting out RF
power. It blinks green during the reception of data or RF carrier or when there is RF
energy on the radio channel.
GPS LED (GPS)
Off: GPS off (in a mode such as MODE RX that does not require use of GPS).
Red: No GPS signal (only active when GPS is used as in MODE TX or MODE TXRX)
Solid Green: Locked to the GPS signals and position acquired.
4.2. DC Power
DC power for the modem comes from a power connector.
5. Configuring the RV-M9
5.1. Command Mode Overview
The Ethernet port on the unit is used to send and receive data over the air, as well as to
configure the RF modem.
The user interacts with the radio via a TCP/IP telnet session, connecting to a
preconfigured IP port (the factory default is port 23). The behavior of any given connected
telnet session depends on the credentials entered during the authentication challenge at
the start of the session.
If the ADMIN role credentials are entered, the corresponding telnet session will be in
Command Mode. The RV-M9 may then be programmed and/or configured.

Company Confidential 12 Raveon Technologies Corp.
If the USER role credentials are entered, the corresponding telnet session will also be in
Command Mode as above; however, in this case, the radio cannot be programmed or
configured. The user can execute certain commands to read settings. Section 5.7 list
the commands, and which ones are available to the user session.
If the DATA role credentials are entered, the corresponding telnet session will be in data
Communication Mode. In this case, data entering the device via the telnet session is
transmitted over the air. Data received from another RF modem is output to the user via
the telnet connection.
The following descriptions detail the Command Mode modem behavior.
5.2. Resetting the IP Address
For the first 30 seconds, the unit listens to the default IP address. (192.168.26.4 port 23).
If someone logs into the default IP address, the unit will reset the user settings back to
default.
5.3. Setting a Parameter
RV-M9 modem parameters may be set via any ADMIN telnet session. To do so, enter
the proper command, a space, the corresponding parameter, and then a carriage return.
For example, to set the destination address of the RV-M9 modem to 1234, enter the
following command:
ATDT 1234 <CR>.
RV-M9 radios automatically save changed parameters to non-volatile EEPROM memory
whenever the parameter value is changed.
5.4. Reading a Parameter
To read the value of a particular setting, issue the command with no parameter via either
an ADMIN or USER telnet session. The modem will return the value followed by an “OK”.
For example, if the user enters the command to read the RV-M9’s destination address
and its address was 1234, the user would issue the following command:
ATDT<CR>
and the modem will respond with:
1234 <CR><LF>
OK <CR><LF>
To get on-line help with a command, enter the command and put a question mark in for
the parameter. For example, to see what the ATDT command is used for, type ATDT ?
<CR>. The modem will respond by listing a brief description of the command. To see a
list of all commands, type HELP<CR>.
5.5. CONFIG Button
If certain parameters within the RV-M9 transponder are modified in a manner that
erroneously causes the modem to cease functioning or if the user cannot enter Command
Mode via an ADMIN telnet session, there is a small push-button internal to the RV-M9 to

Company Confidential 13 Raveon Technologies Corp.
assist in this situation. This “CONFIG” button may be pressed at any time, and forces the
RV-M9 into a known operational state. The CONFIG button is located inside the RV-M9.
The default settings that the RV-M9 will revert to when the CONFIG button is pressed
are:
1. All User Name and Password combinations reset to factory default.
2. All User parameters are reset to factory default.
3. Encryption KEYPHRASE is erased
Important Note! For security reasons, if the CONFIG button on the RV-M9 is pressed,
the encryption KEYPHRASE is automatically erased and reset back to the factory default
KEYPHRASE and all User Name and Password combinations are reset to factory
defaults.
5.6. Restoring Factory Defaults
The AT&F command may be used to restore the unit back to the factory-default condition.
The table in Section 5.7 lists all of the radio modem related commands. Use this
command with caution, as it will erase all previously configured parameters. It will cause
the modem to revert back to the factory-defaults, as shown in the command table,
“Factory Default” column. The only parameters that it does not restore to default are the
radio calibration values R0-R9, and RA.

Notes:
1. “Dotted quad decimal” notation is also known as “dotted decimal” notation.
2. Because changes to these settings may disable Ethernet access to the radio modem, requested changes to these settings must
be confirmed by user action. Immediately following entry of each of these parameter change requests, the RV-M9 will respond
with:
Enter YES<CR> to confirm this configuration change, or NO<CR> to cancel it.
3. Changes to these parameters may only be supported via the factory serial port interface.
