2.Overview
The RF-7800W GPS transponder is a rugged, high-speed UHF data modem with a built-
in 12-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.
The RF7800W Ethernet port provides both power (Power-Over-Ethernet) and
communications by means of an integrated Ethernet 10/100 Base-T interface.
For privacy and security, over-the air encryption is standard on every RF-7800W radio.
For radio network versatility, the RF-7800W incorporates a 16-bit identification code,
allowing up to 65,000 units to be identified in one system. For wide-area coverage, all
RF-7800W transponders may be set to store-and-forward messages from other RF-
7800W 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 RF-7800W 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.
System Mode:

RX
TXRX P
TXRX S

Any RF-7800W 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 RF-7800W 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 RF-7800W is a TCP/IP Telnet server.
The RF-7800W 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 RF-7800W. 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 RF-7800Wis 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 RF-
7800W, 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:
Login:
The client must enter the Login Name followed by a <return>. The unit will then respond
with:
Password:
The client must enter the password followed by a <return>.
Upon successful login authentication, the unit will respond with:
Prompt:
where the prompt can be set with command PROMPT XXXXXX. After three failed
attempts to enter a correct username/password combination, the session will be
terminated.
3.5. Session Modes
The RF-7800W ‘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 RF-7800W 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:
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.
