Overvie
The FireLine RF data radio is a rugged high-perfor ance, high-speed narrow-
band data ode . It contains a receiver, a trans itter, and ode , creating
an easy-to-use transparent data radio link. The FireLine’s user interface is
asynchronous data into and out of the FireLine. Mode operation is virtually
transparent to the user and the configuration of the ode is via the user
serial port.
For privacy and network versatility, the FireLine incorporates a 16 bit
identification code. Its protocol also uses a 16bit CRC to guarantee the
integrity of the data. Perfect for SCADA and tele etry applications, the
FireLine can be used for si ple point-to-point data co unication
applications, or for ore sophisticated point-to- ultipoint, peer-to-peer, or
esh networks.
Although the FireLine is the easiest to use ode on the arket, its re-
progra ability akes it extre ely versatile. Most para eters within the
ode ay be re-configured to opti ize it for specialized operations,
extended range, or higher data throughput.

Front Panel
The front panel of the FireLine ode has these features:
1 BNC RF connector
2 Transmit LED (TX)
3 Receive LED (RX)
4 Power LED (PWR)
5 9-Pin serial I/O connector
6 DC Power Jack
LEDs
The three status LEDs visually show the current status of the radio.
Transmit LED (TX) This LED blinks red when the trans itter keys and is
putting out RF power.
Receive LED (RX) This LED glows red when there is an RF signal on the
radio’s receive frequency. This LED will indicate the presence of any signal,
even one fro other sources or radios, data, or voice. If it glows steadily at
all ti es, there is probably so e other user on the radio channel.
Power LED (PWR) This has a short blink, once every two seconds,
indicating to the user that the power to the ode is ON and the ode is
working. When the ode is in the co and ode, this LED will blink on
and off, once per second. In the nor al operating ode, this led will also
glow red when data is received over the air.
DC Po er
DC power for the ode is connected to the 2-pin DC power input jack
labeled DC IN.
Its connection is optional, as the user ay alternately apply power to Pin 9
and ground to pin 5 of the 9-pin I/O connector,.

User I/O Connector
The User I/O is via a fe ale 9-p D-sub iniature connector. The following
pins are defined.

Note: RS-232 signals use positive and negative voltages to represent digital 1s and 0s. A positive
voltage is a 0, and a negative voltage is a digital 1.
This pin-out allows it to be directly plugged into a co puter’s 9-pin serial port
using a conventional serial cable. To connect it to a ode , or co puter
peripheral that has a serial port, you will need a “null- ode ” cable. See
Appendix A for ore infor ation on wiring a null- ode cable.

Using the FireLine Modem
Setup
1. Connect a DC power source to the DC IN connection on the front of the
ode .
2. Connect a good quality antenna, cut to the operating frequency, to the
BNC connector on the front of the ode . Use a good antenna, and
place is at high-above obstructions as possible.
3. Connect a co puter ter inal, or PC co puter running HyperTer inal, to
the 9-pin I/O connector.
4. Progra the ode ’s operating frequency to your desired operating
frequency. Using the AT co ands, change any of the default operating
para eters that ust be odified. See the section “Serial Port
Commands” for infor ation describing the various para eters that ay
be odified in the ode . In ost applications, the default settings fro
the factory will work fine.
5. Connect your serial data device to the 9-pin connector on the front of the
ode . The default serial port settings are 9600bps, 8 data bits, 1 stop
bit, no parity.
The radio is now ready to use. Any serial data going into the ode will be
trans itted over the air, and any data received over the air will be sent out the
serial port.
Addressing
One of the ore powerful aspects of the FireLine ode is its addressing
sche e. Each FireLine contains a 16 bit address, called its Unit Address,
and is represented as a 4 digit hexadeci al nu ber. FireLine address ay
be any nu ber between 0000 and FFFF, which is 65,535 different addresses.
For those not fa iliar with hexadeci al nu bers, a hexadeci al digit
represents a 4-bit binary pattern. There are 16 possible values
(0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,and F). These 16 values represent 4 bits of
infor ation, thus 4 hexadeci al digits can represent 16 bits of infor ation.
The hexadeci al nu bers represent 4 bit data in the following way:
Hexadecimal Table
Hex # Binary Hex # Binary Hex # Binary Hex # Binary
0 0000 5 0100 8 1000 C 1100
1 0001 6 0101 9 1001 D 1101
2 0010 7 0110 A 1010 E 1110
3 0011 8 0111 B 1011 F 1111
When co unicating over the air, FireLine ode s trans it their Unit
Address along with the data. Receiving ode s check the received Unit

Address, and see if it atches their address. If it does atch, the receiving
doe outputs the data it received via its serial port. If it does not atch, the
receiving ode discards the data, and does not send it out the serial port.
The Address Mask
The reason to use hexadeci al digits to represent the unit address, is that
along with the Unit Address progra ed into the FireLine, there is an
“Address Mask” progra ed into it. The default ask is FFFF. The address
ask is also used to deter ine if a particular data trans ission should be
received by the ode . For ost applications, where one ode talks to
one ode , or where all ode s in the syste co unicate with all other
ode s in the syste , the Address Mask should stay set to FFFF.
Only in syste s where so e ode s should only talk to certain other
ode s, will you want to change the address ask. Whenever data is
received over the air, the Unit Address of the device that sent the data is
logically “ANDed” with the Address Mask in the receiving ode . This is the
Effective Trans ission Address. The receiving FireLine also ANDs its own
Unit Address with its Address Mask. The result is the effective Unit Address.
The Effective Unit Address is co pared to the Effective Trans ission
Address, and if the two are identical, the data will be received.
Note: Logically 1 AND 1 = 1, 0 AND 0 = 0, 1 AND 0 = 0, 0 AND 1 = 0
`
One effect of this is that an address ask of 0000 will cause the FireLine
ode to received any data fro any unit that trans its. The Unit Address
will effectively be ignores if the ask is set to 0000.

Examples:
Exa ple 1 (default configuration)

Receiving Unit Address = 1234
Receiving Unit’s Address Mask = FFFF
Result: Unit will receive the data, because the addresses identically atch. When the
addresses are identical, the value of the ask is not i portant.
Notes: This is the default configuration. All units have address 1234, and all ode s will
talk to all other ode s with address 1234.
Exa ple 2 (a configuration that won’t work)
Sending Unit Address = 1236
Receiving Unit Address = 1234
Receiving Unit’s Address Mask = FFFF
Result: No data will be received, because the address do not atch, and the address
ask of FFFF requires that all digits in the address atch. .
Exa ple 3 (able to receive a data fro a group, 1230 – 123F)
Sending Unit Address = 1236
Receiving Unit Address = 1234
Receiving Unit’s Address Mask = FFF0
Result: Data will be received. 1236 ANDed with FFF0 is 1230. 1234 ANDed with FFF0
is 1230. The results of the ANDing atch, and thus the data will be received.
Exa ple 4 (able to receive fro a group, xx34 where xx is any two digits)
Sending Unit Address = 2234
Receiving Unit Address = 1234
Receiving Unit’s Address Mask = 00FF
Result: Data will be received. 2234 AND 00FF equals 0034. 1234 AND 00FF equals
0034, therefore they atch. The results of the ANDing atch, and thus the data will be
received.

Installation
1. Secure the FireLine ode using the four ounting holes on the side
flanges of the unit.
2. Connect a DC power source to the DC IN connection on the front of
the ode .
3. Connect a good quality antenna, cut to the operating frequency, to the
BNC connector on the front of the ode . Use a good antenna, and
place is at high-above obstructions as possible.
4. A separation distance of at least 20 centi eters ust be aintained
between the trans itter's radiating structures and the body of the user
or nearby persons.
5. Connect a co puter ter inal, or PC co puter running HyperTer inal,
to the 9-pin I/O connector.
6. If the antenna is ounted out doors, us a lighting arrestor in-line with
the antenna, and properly ground the antenna and the FireLine chassis
to an earth ground.
FCC Licensing Information
FireLine radio ode s operate on radio frequencies that are regulated by the
Federal Co unications Co ission (FCC). In order to trans it on these
frequencies, you are required to have a license issued by the FCC.
Al ost everyone engaged in public safety activities - as well as private
organizations, are required, to obtain a radio station license fro the Federal
Co unications Co ission if they wish to use a radio trans itter.
The FCC will help you through the licensing process.
You can find the basic infor ation you need to begin the process at the FCC
website. If you are engaged in public safety activities, you can go directly to:
http://wireless.fcc.gov/publicsafety
If you are a business, co ercial, or institutional organization, you can go
directly to:
http://wireless.fcc.gov/services/ind&bus
In either case, you will be shown the regulations and the infor ation you will
need to gather before you get started - your desired operating frequencies,
wideband/narrowband, antenna type and size, power/wattage, etc. You'll also
get infor ation on how to obtain the necessary application for s - either in
hard-copy or electronic for at - and how to proceed.

The FCC website also offers a list of Frequency Coordinators. These are
private organizations officially certified by the FCC to help you through the
process, and who in ost cases will handle the actual filing of your
application. With few exceptions, you ust apply for an FCC license through
a Frequency Coordinator. They are located throughout the country, aking it
easy for you to find one that is fa iliar with radio operations in your area.

Serial Port Data and Handshaking
In co puter ter inology, the RF ode is considered a “Data
Co unications Equip ent” device, or DCE. The user’s hardware that the
ode is connected to is considered “Data Ter inal Equip ent”, or DTE.
Following is a description of how data and control is co unicated over the
various serial port signals between the ode (DCE) and another device
(DTE) that the ode ’s I/O port is connected to.
TxD (INPUT)
This line is used to trans it data fro the DTE to the DCE. It is aintained at
a logical 1 state when nothing is trans itted. If Hardware Flow Control is
enabled in the ode , the ter inal will start to trans it data to the ode
when a logical 1 is present on all of the following lines:
• Clear To Send (output fro ode )
• Request to Send (output fro the DTE)
RxD (OUTPUT)
This circuit is used to receive data fro the DCE to the DTE. The ode will
start to trans it data to the DTE when a logical 1 is present on all of the
following lines:
• Data Ter inal Ready (reply that it is OK to send)
• Data Set Ready (asserted by the ode )
RTS
On this line, the DTE will send a signal when it wants to receive data fro the
FireLine ode . The FireLine ode will not output data unless this pin is
low, or “Flow Control” has been disabled in the ode set-up. When a DTE
(such as a PC or icrocontroller) wants to stop the flow into it, it negates
RTS. Negated "Request To Send" (digital 1) eans "request NOT to send to
e" (stop sending). When the DTE is ready for ore bytes it asserts RTS
(digital 0) and the flow of bytes to it resu es. DCE equip ent works the sa e
way but sends the stop signal out the CTS pin. Thus it's RTS/CTS flow control
using 2 lines. The user ay turn this feature off or on, using the ATCH
co and. The default is OFF. To turn it on, issue an ATCH 1 co and.
CTS
This signal is an output fro the FireLine, and it indicates the FireLine’s ability
to send ore data. If the user tires to send ore data into the FireLine than
the FireLine can trans it over the air, it will negate the signal on this pin. The
CTS ay be asserted when the serial-port data rate is greater to or equal to
the over-the-air rate. For exa ple, if the over-the-air data rate is set to 2400
baud, and the user is send data into the ode at 9600 baud, the ode

will negate the CTS signal once the FireLine’s internal data buffers beco e
full.
CD
On this line the ode indicates to the DTE that it has received a carrier
fro a re ote device. It will assert this signal any ti e there is a carrier
detected. The ode ay be configured to assert this when an RF carrier is
detected (any on-channel RF, voice or data), assert it only when another RF
ode signal is detected, or always assert it. The operation of this line is
configured with the ATR1 co and. The default is 1 (asserts when FireLine
data is detected on the radio receiver).
DTR
This line is an input to the FireLine. It is nor ally ignored because the default
configuration of the FireLine ode is to ignore this signal. If the DTR line is
enabled for use, using the ATK5 1 co and, the DTR input line can be used
to put the FireLine ode into its SLEEP ode. With DTR enabled, anyti e
the DTR line is a logic 0, the FireLine will be operating nor ally. With DTR
enabled, anyti e the DTR line is a logic 1, the FireLine will go into a SLEEP
ode, drawing uch less DC power.

User Serial Port Commands
Overvie
The asynchronous serial portion the RF ode is used to send and receive
data over the air, as well as to configure the RF ode . In nor al operation,
the user sends data into the TxD pin of the user port, and this data is
trans itted over the air. Received data fro another RF ode is output to
the user via the RxD pin of the user port. This is the default operating
condition of the RF ode .
There also is a “Co and Mode”. In the Co and Mode, the FireLine
ode accepts co ands via the TxD pin. The co ands can be used to
change certain internal para eters of the FireLine ode .
Command Mode
The FireLine ode ay be put into a “Co and Mode”, by entering a
sequence of three plus characters (+++). To keep the FireLine ode fro
accidentally entering the Co and Mode because of the +++ pattern
occurring in a strea of data entering the ode , there ust be a pause in
the data strea before the +++ as well as after the +++ is sent. If either
pause is issing, the ode will not enter the co and ode.
Using serial co unications software such as H pterTerminal, send the 3-
character co and sequence “+++” while observing ti es of silence before
[BT (Silence Before Sequence) Co and] and after [AT (Silence After
Sequence) Co and] the co and characters.
The default sequence for entering into AT Command Mode:
The default sequence for entering into AT Command Mode: The default sequence for entering into AT Command Mode:
The default sequence for entering into AT Command Mode:
1. No characters sent for 1 second.
2. Input three (3 plus characters (“+++” within one (1 second.
3. No characters sent for one (1 second.
When the FireLine ode first enters the Co and Mode, it sends the
phrase “FireLine” out it serial port, and then an “OK” sequence. The “OK”
sequence is a sequence of 4 characters:
An “O”, “K”, <CR>, and <LF> characters
(<CR> = ASCII 0D, <LF> = ASCII 0A)
Setting a Parameter
To set a para eter in the FireLine ode , enter the configuration ode as
described above. Then enter the proper AT co and, a space, the
para eter, and then a carriage return. For Exa ple, to set the address of the
FireLine ode to 1234, enter the following co and:
ATDT 1234 <CR>.

Reading a Parameter
To read the value of a particular setting, issue the co and, with no
para eter. The ode will return the value followed by an “OK”. The
ode ’s OK response is:
The value in ASCII deci al for at.
A <CR> <LF> (<CD> = ASCII 0D, <LF> = ASCII 0A).
An “O”, “K”, <CR>, and <LF> sequence.
For example, if the user enters the command to read the FireLine’s
modem address and its address was 1234, the user would issue the
following command:
ATDT<cr>
and the modem will respond with:
1234<CR> <LF>
CONFIG Button
If certain para eters within the ode are odified in a anor that causes
the ode to cease functioning or if the user cannot enter the co and
ode via the “+++” ethod described above, there is a s all push button
internal to the FireLine ode to assist. This CONFIG button ay be
pressed at any ti e, and forces the ode into a know operational state.
The CONFIG button is located inside the ode . Re ove the rear cover,
exposing the two circuit boards. The button is in the center of the lower circuit
board as shown below.
The default setting that the ode will revert to when the CONFIG button are
pressed are:
1. Serial port 9600 baud, 8 data bits 1 stop, no parit
2. ATCT setting set to 60000 (60 second time-out)
Even though the serial baud rate reverts to 9600 baud when the CONFIG
button is pressed, it will revert back to the ATBD setting progra ed into the
ode once the Co and Mode is exited.
