1. General Information about the RV-PMTII
1.1. Congratulations!
Congratulations on your purchase of a RV-PMTII OEM radio.
Please take a few minutes to read this manual carefully. The information presented here
will allow you to derive maximum performance from your radio modem. After reading it,
keep the manual handy for quick reference, in case questions arise later on.
1.2. NOTICE
There are no user-serviceable points inside this transceiver. All service work must be
referred to your Authorized Service Center or Raveon Technologies Service Department.
IMPORTANT NOTICE !
Because of the nature of wireless communication, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors), or be totally lost. Significant delays
or losses of data are rare when wireless devices, such as the PMTII, are used in a normal manner
with a well-constructed network.
This radio should not be used in situations where failure to transmit or receive data could result in
damage of any kind to the user or any other party, including but not limited to personal injury, death,
or loss of property.
Raveon accepts no responsibility for damages of any kind resulting from delays or errors in data
transmitted or received using the PMTII, or for the failure of the PMTII to transmit or receive such
data.
1.3. Safety / Warning Information
Service
This equipment should be serviced by qualified technicians only.
Blasting Caps and Blasting Areas
To avoid possible interference with blasting operations, turn off this radio or remove the DC
power when you are near electrical blasting caps, in a blasting area, or in areas posted:
“Turn off two-way radio.” Obey all signs and instructions.
Potentially Explosive Atmospheres
Turn off your radio prior to entering any area with a potentially explosive atmosphere. Do
not install this product for use in areas with potentially explosive atmospheres. Do not
remove, install, or charge batteries in such areas. Sparks in a potentially explosive
atmosphere can cause an explosion or fire resulting in bodily injury or even death.
Note: The areas with potentially explosive atmospheres referred to above include fueling areas such as
below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or
particles, such as grain, dust or metal powders, and any other area where you would normally be advised to
turn off your vehicle engine. Areas with potentially explosive atmospheres are often but not always posted.

FCC MPE Regulations:
WARNING: It is the responsibility of the user to guarantee compliance with the FCC MPE
regulations when operating this device in a way other than described in this manual.
Human Body Exposure:
This equipment is approved only for mobile and base station transmitting devices,
separation distances of
(i) 26 centimeters or more for antennas with gains of 0 dBi or less or

1.4. Part 15 Note:
This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

2. Overview
The RV-PMTII compliant Data radio modem is capable of high-speed wide-band data
communications. It contains a transmitter, and a modem, creating an easy-to-use
transparent data radio link. The built-in DTMF protocol is compatible with many legacy
systems. This radio modem is not compatible with Raveon’s M7 series of data radio
modems.
2.1. Features
Small sized and single-board construction.
Highly efficient battery life (15µA sleep mode)
Reliable and fast wakeup
Seamless integration into legacy systems
Immediate audible user feedback

4. Data Transmission
To transmit data, simply press a button on the interface. As soon as a full packet
of data has been generated and collected into the internal buffer of the modem,
the modem will automatically key its transmitter, and send the data over the air.
5. Debug Related Features
Bench Testing
(Must be connected to a service monitor and/or spectrum analyzer)
All debug options below are entered by pressing ACCESS CODE + the following buttons:
1 Keys the unit to CW
2 Keys the unit with a square wave
3Sends all DTMF characters sequentially
UP Sends the DTMF character A multiple times
DOWN Sets the access code for the unit
7 or ON/OFF Enable/Disable Override Mode
8 + 8 + 8 Reset unit to factory defaults
When finished, any transmissions can be ended by pressing the OFF button alone.
Note: Unwanted characters may have been generated at this time. It is recommended to
simply press any key after using these modes to ensure unit is working as intended.

6. Tune-up and Alignment
The RV-PMTII modem has been factory calibrated, in should not require any re-
calibration when installed. The unit cannot be tuned or adjusted without the
proper test board. The following section assumes access to the required test
board.
This unit is sensitive to input voltage. Improperly attempting to connect to
the unit could result in permanent damage.
6.1. Periodic Calibration
The only setting that may require adjustment is the center frequency. After years
of operation, all crystals will age and change frequency slightly. Like all narrow-
band radios, semi-annual checks and adjustment of frequency is recommended.
6.2. Calibration Commands
The following AT commands are used to calibrate the PMTII when connected to
a test board. Do not ever change these unless you have been factory trained to
do so.
AT
Command
Command Description
Parameters
Factory
Default
R0
Symbol Peak Deviation –Set the peak FM deviation of
the transmit symbols. Note: This can be a negative
number to invert the modulation.
Range: -1000 –1000
120**
R1
Select CD pin output signal –CD pin may be RF
carrier detect, or modem data detect, off, on, or RX data
framing, or on-line status. Line status mode asserts CD
when on-line in normal modem operation and it negates
CD when in the command mode.
Range : 0 - 5
5 = RX data framing. Assert
when outputting data
4 = Line stat.
3 = Always negate CD
2 = Always assert CD
1 = Data CD
0 = RF CD
0
(RF Carrier)
R2
Over-The-Air bit rate -This is the data rate the radio
uses to send data over the air. All RF modems in the
network must use the same over-the-air baud rate.
Range:
0 = 800 5 = 9600 2L
1 = 1200 6 = 19200 4L
2 = 2400 7 = 5142 2L
3 = 4800 8 = 9600 4L
4 = 8000 4L 9 = 2000 2L
3
R3
Serial Port time out –Number of mS of no activity on
the serial port before transmitting the data in its buffer.
Range: 1 - 5000
20 (mS)
R5
Preamble length –The number of bytes to send over-
the-air in the pre-amble.
Range: 3 - 255
4**
(Varies based
on data rate
and radio
type. 7 typical)
R8
Frequency Offset. Used to set the radio on the center of
the radio channel.
Range: -500 to +500
0**
R9
Modulation Balance.
Range: 0-100
20**

6.3. Center Frequency
1. Key the transmitter with CW output using this command:
ATTD 7
2. The modem will now put out CW on the center of the channel.
3. Read the frequency offset with the ATR8 command.
4. Adjust the frequency to the center of the channel with the ATR8
command. You can use the “U” key and the “D” key to change the
settings up and down one value in real time.
6.4. TX Deviation
1. Switch to channel 1.
2. Key the transmitter into a 50 ohm load using the ATTD 3 command. The
unit will now transmit, and send a digital 0 continuously. This should be
+2.0kHz in frequency for narrow-band radios (12.5kHz spaced channels)
and +3.0kHz for wide-band (25kHz channels).
3. Adjust the deviation register setting so that the frequency deviation is
correct. The deviation is set with a digital adjustment. Use the ATR0
command to read or set the deviation level.
