INTRODUCTION
External extra rugged digital high power UHF radio transceiver programmable in frequency ranges from
406 to 470 MHz. It has GMSK, DBPSK, DQPSK, 4FSK, D8PSK, and D16QAM modulations with
advanced forward error correction and data scrambling. The output power is programmable up to 4 W.
Figure 1-1. HPT404BT

The HPT404BT radio transceiver provides a high-speed Point-to-Point and Point-to-Multipoint wireless
data transfer at up to 38.4 kbps. HPT404BT supports user selectable modulation techniques (GMSK,
4FSK, DBPSK, DQPSK, D8PSK, or D16QAM), which allows the user to achieve the highest data speed
for a given range (up to 16 miles / 26 km). It also includes a selectable error correction, which improves
the functioning of the radio modem under interference.
The sophisticated features of HPT404BT include data scrambling, frequency hopping, user selectable
transmit output power level, low power consumption sleep modes, autoscanning and plug-and-play
installation for remote terminals.
The built-in software tools provide the wireless link testing, unit’s status and error statistics monitoring as
well as unit’s settings change over the air. The firmware of the HPT404BT radio transceiver resides in a
flash memory. The updating of the radio modem programs is entirely software-based. The flash memory
is re-programmable through an RS232 interface, USB, Bluetooth, or over the air. The unit’s user settings
can be changed through the built-in Command Line interface (CLI), Tracy Software or through
ModemVU.

1.1.6. Literature
HPT404BT literature, including manuals and other product information are available on the JAVAD
GNSS website (http://www.javad.com):
•HPT404BT Operator’s Manual
• Functional specifications
1.1.7. External Antenna (not included)
Antenna type depends on the site requirements, and may be directional or omni-directional.
Warning: Do not use HPT404BT without antenna our attenuator to avoid serious damage of your device.
1.1.8. Storage Precautions
1. Always clean the instrument after use. Wipe off dust with a cleaning brush, then wipe off dirt with
a soft cloth.
2. Store in a location with a temperature of -40°... +85°C, and no exposure to direct sunlight.
3. Use a clean cloth, moistened with a neutral detergent or water, to clean the modem. Never use an
abrasive cleaner, ether, thinner benzene, or other solvents.
Always make sure the instrument is completely dry before storing. Dry the modem with a soft, clean
cloth.

CONFIGURATION
2.1. Powering HPT404BT
To power HPT404BT use the Battery kit 1 (p/n 99-587300-10).
Figure 2-1. Battery Kit 1
2.1.1. Power supply requirements
A single external power supply is necessary to operate HPT404BT. The external power supply needs to
be Listed for US and Certified for EU countries, it needs also to be a Limited Power Source and rated for
Outdoor Use and have an output rated for +9 ... +36V, 4A. This may not be the same range as other
JAVAD GNSS products with which you are familiar.
C AUTION : To avoid the introduction of hazards when operating and installing, before connecting of the equip-
ment to the supply, make sure that the supply meets local and national safety ordinances and
matches the equipment’s voltage and current requirements.
Never attempt any maintenance or cleaning of the supply while plugged in. Always remove supply
from AC power before attempting service or cleaning.
Warning: If the voltage supplied is below the minimum specification, the modem will suspend operation. If the voltage
supplied is above the maximum specification, the modem may be permanently damaged, voiding your
warranty.
Make sure cords are located so that will not be stepped on, tripped over, or otherwise subjected to
damage or stress. Do not operate equipment with a damaged cord or plug – replace immediately.
To reduce the risk of damage to the equipment, pull by the plug body rather than the output cord
when disconnecting the equipment.
Do not operate the supply if it has received a sharp blow, been dropped, or otherwise damaged. Do
not disassemble the supply.

Warning: Before connecting the external power source and the modem, make sure that the power source matches the
modem’s voltage and current requirements.
2.2. Antenna Installation
Warning: To avoid the equipment serious damage, do not switch the modem to transmit mode if RF antenna is not
connected!
Select the type of antenna that best fits your application and the one that offers the highest dB gain. In
addition, setup your system in the highest possible location to minimize obstacles between the
transmitting and receiving systems. Always place the antenna on the highest point available. At a
minimum, set the antenna to at least ten feet above the terrain using an antenna mast.
Some antennas intended to be attached to the pole mount adaptor (p/n 14-578117-01) are designed to be
operated with a ground plane and some without it. Antennas operating without ground plane marked in
our catalogue as NGP, e.g. UHF NGP Antenna 1/2, 2.4 dB gain, NMO:
• p/n 30-587307-01 UHF NGP Antenna 406-430 MHz, 1/2, 2.4 dB, NMO
• p/n 30-587308-01 UHF NGP Antenna 430-450 MHz, 1/2, 2.4 dB, NMO
• p/n 30-587309-01 UHF NGP Antenna 450-470 MHz, 1/2, 2.4 dB, NMO
This antennas are NO GROUND PLANE antennas with gain 2.4 dB and NMO specified connector type
with should match with your antenna adapter (pole mount or magnet mount). Antennas designed to be
operated with ground plane
• p/n 30-587303-01 UHF Antenna 406-430 MHz, 5/8, 5 dB, NMO
• p/n 30-587304-01 UHF Antenna 430-450 MHz, 5/8, 5 dB, NMO
• p/n 30-587305-01 UHF Antenna 450-470 MHz, 5/8, 5 dB, NMO
provide better gain, but to achieve the best performance of your antenna, add a UHF Antenna Ground
Plane Disk (p/n 10-587400-01) to the bottom of the antenna for a ground plane. UHF antenna Ground
Plane disk improves VSWR and as result increase RF power delivered from transmitter to antenna and
system distance range.
To install antenna with ground plane disc (see pictures below):
1. Unscrew the cone-shaped cable part;
2. Place the ground plane disc between cable parts and screw all parts together;
3. Attach cable with ground plane to the UHF antenna;

4. Place the antenna on the pole.
Use coaxial cable and connectors that are impedance-matched with the radio equipment, and make sure
to use the shortest length of cable to move the signal between the radio and the antenna:
• p/n 14-578115-01 Accessory UHF Ant Cable BNC/Magn Mount, 12ft1
• p/n 14-578116-01 Accessory UHF Ant Cable BNC/Mini-Magn Mount, 12ft1
• p/n 14-578117-01 Accessory UHF Ant Cable BNC/Pole Mount, 12ft

2.3. Installing ModemVU
ModemVUTM is a Windows® application is a configuration program for the radio modem. ModemVU is
available from the JAVAD GNSS website.
Note: Refer to the ModemVU Software Manual for full details on installing and using ModemVU Software.
ModemVU is JAVAD GNSS’s configuration utility for external modems and modems embedded in
JAVAD GNSS modems. ModemVU provides the following functions:
• Connecting a computer to an UHF modem via a serial port.
• Displaying information about the radio modem installed in the modem.
• Programming the radio modem’s settings.
• Loading the new modem firmware.
To configure the HPT404BT modem, have the following ready:
• Computer running Windows®;
• ModemVU Software installed on the computer;
• A serial cable.
1. If downloading the program from the website, extract the program files into a folder on your hard
drive.
2. Navigate to the location of the ModemVU program and double-click the Setup.exe icon.
3. Follow the on-screen installation instructions. Click Next to continue, Back to get back to previous
step, or Cancel to quit the installation.
4. Keep the default installation location or select a new location.
5. Click Finish to complete the installation.
6. If desired, create a shortcut on the computer’s desktop for quick access to ModemVU.
To uninstall ModemVU use the Start menu on your computer:
1. Navigate to the location of the ModemVU program and double-click the Setup.exe icon.
2. Follow the on-screen installation instructions.

Once you have established a connection between the modem and the computer, you will be able to:
• Configure the modem and its components
• Send commands to the modem
Use ModemVU to load new firmware to the modem.
2.4.1. Connecting through serial port
To configure, or maintain HPT404BT, you need to connect the modem and a computer using an
Accessory Data-Ser-Pwr Cable, DB9/DB15/SAE (1,8m), p/n14-578108-02.
Figure 2-2. Accessory Data-Ser-Pwr Cables DB9/DB15/SAE
