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 from 320 mW to 35 W.

Figure 1. HPT435BT

The HPT435BT radio transceiver provides a high-speed Point-to-Point and
Point-to-Multipoint wireless data transfer at up to 38.4 kbps. HPT435BT
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 48 miles / 77 km). It also in­cludes a selectable error correction, which improves the functioning of the
radio modem under interference.

The sophisticated features of HPT435BT 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 rmware of the HPT435BT radio transceiver resides in a ash memo­ry. The updating of the radio modem programs is entirely software-based.

The ash 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), FieldCAD, Tracy Software or
through ModemVU.

Figure 6. Battery Kit 2

Warning: Powering HPT435BT please observe polarity!

Power supply requirements

A single external power supply is necessary to operate HPT435BT. The

external power supply needs to be Listed for US and Certied for EU

countries, it needs also to be a Limited Power Source and rated for Outdoor
Use and have an output rated for +9 ... +16V, 10A. This may not be the
same range as other JAVAD GNSS products with which you are familiar.

CAUTION: 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.

CAUTION: 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 specication, the modem

will suspend operation. If the voltage supplied is above the maximum specication, the

modem may be permanently damaged, voiding your warranty.

Warning: 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.

Warning: 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: Warning: Before connecting the external power source and the modem,

make sure that the power source matches the modem’s voltage and current requirements.

Antenna Installation

Warning: To avoid the equipment serious damage, do not switch the modem to trans-

mit mode if RF antenna is not connected!

Select the type of antenna that best ts 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 adapter (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:

• UHF NGP Antenna 406-430 MHz, 1/2, 2.4 dBd gain, NMO

• UHF NGP Antenna 430-450 MHz, 1/2, 2.4 dBd gain, NMO

• UHF NGP Antenna 450-470 MHz, 1/2, 2.4 dBd gain, NMO

Theses antennas are NO GROUND PLANE antennas with gain 2.4 dB

and NMO specied connector type with should match with your antenna

adapter (pole mount or magnet mount). Antennas designed to be operated
with ground plane

• UHF Antenna 406-430 MHz, 5/8, 5 dBd gain, NMO

• UHF Antenna 430-450 MHz, 5/8, 5 dBd gain, NMO

• UHF Antenna 450-455 MHz, 5/8, 5 dBd gain, NMO

www.javad.com 11

• UHF Antenna 455-460 MHz, 5/8, 5 dBd gain, NMO

• UHF Antenna 460-465 MHz, 5/8, 5 dBd gain, NMO

• UHF Antenna 465-470 MHz, 5/8, 5 dBd gain, 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):

• Unscrew the cone-shaped cable part;

• Place the ground plane disc between cable parts and screw all parts
together;

• Attach cable with ground plane to the UHF antenna;

• 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:

• UHF Ant Cable TNC/Pole Mount, 12ft

• UHF Ant Cable TNC/Magn Mount, 12f [Substract $55]

• UHF Ant Cable TNC/Mini-Magn Mount, 12ft [Substract $55]

Fan for radio

The most efcient way to increase duty cycle of the HPT435BT transceiv­er is using the Fan kit (p/n 02-587101-31) shown on the picture below:

Figure 7. Fan for radio

status. It is the most powerful tool to congure the unit. It makes changes

to all possible settings that system will not be able to determine automat­ically.

The CLI commands allow user to congure and recongure the unit’s set­tings. The user conguration parameters that could be changed through

the CLI are:

• Data Port Settings

• Baud Rate

• Data Bits (8, 7)

• Parity (Odd, Even, None)

• Flow control (None or RTS/CTS)

• Alarm Settings

• Radio Operation Modes

• Sleep modes

• On/Off

• Activate by internal real-time clock

• Activate through RTS/CTS lines

• Activate by external sense lines

• Activate by any combination of the parameters mentioned before

Note: The unit’s conguration that is set or modied through the CLI will be lost after

unit’s reboot, unless the saving operation is used to store a new setting in the unit’s con-

guration le.

The CLI commands also provide ling operations, which include:

• Downloading Unit’s Conguration les

• Software Images

• Uploading Unit’s Conguration les

• Saving into the conguration les the conguration parameters mod-

ied through the CLI.

Command Line Interface Convention

The following convention is implemented in HPT435BT Command Line
Interface (CLI):

• The Carriage Return/Line Feed (CR/LF, 0x0D/0x0A) is a command
delimiter.

• The Carriage Return/Line Feed (CR/LF, 0x0D/0x0A) is a reply de­limiter followed by the “CLI>” prompt if Echo option is On.

• The Carriage Return/Line Feed (CR/LF, 0x0D/0x0A) is a reply de­limiter if Echo option is Off (default option).

• The 2-digit number followed by “@” in the unit’s reply indicates the
error code (refer to Table 3 for description), if Echo Off is selected,
otherwise the error message is displayed.

• A successfully performed command is replied by @00 code, if Echo
Off is selected, otherwise the set value is replied.

• A command with the certain [Parameter Name] and blank [Parameter
List] displays the current settings for a given parameter.

• To set the mode ordered by CLI commands as permanent User Set­ting (the setting automatically selected for the boot-up unit) the SAVE
command must be asserted.

• A command followed by “/F” option displays the Parameters in the

predened frame format. The display frame format is unique for each

command supporting “/F” option.

Table 1. Command Line Interface Error Codes

Software Switching to Command Mode

On power-up the radio modem is in data-mode. To switch to command
mode the special byte-sequences with special meanings are used:

• Escape-Sequence: “+++” with 20 ms guard time before and after the
command characters

• Escape-Acknowledge: “@00<CR><LF>”

20 ms toggling on CTS control line needed to acknowledge switching
from Data to Command mode and vice versa.

Happy Flow

• In data-mode the unit starts looking for the Escape-sequence if there
is no data from DTE (Data Terminal Equipment) for more than 20 ms
(Start Guard Time).

• If the unit detects the Escape-Sequence:

• The transmitter continues sending over the air the data received from
DTE before Escape- Sequence and buffers the data from DTE;

• The Receiver immediately stops forwarding to DTE the data received
over the air and buffers it instead.

• The radio unit waits for 20 ms and then sends Escape-Acknowledge
to DTE if there is no data from DTE during 20 ms of Stop Guard Time.

• The unit goes to command mode and discards Escape-Sequence from
input buffer. The modem is immediately ready to receive commands.
At the same time it continues buffering the data received over the air
since step 2.

Escape-Sequence in Data

During its waiting in step 3, the unit receives data from DTE:

• The unit sends buffered Escape-Sequence from DTE to the air;

• The unit sends all buffered data received from the air since step 2 to
DTE and stays in data-mode (i.e. transmits data received from DTE
over the air – including the just received, unexpected, data and forwards
data received over the air to DTE.)

Hardware Switching to Command Mode

As alternative to Software Switching, the switching through the MP/DP
(Data Terminal Ready, DTR) control line can be used. To set Command
Mode, the DTE must assert DTR signal active and then passive. By fall­ing edge of DTR signal the unit goes to command mode and then sends
Escape- Acknowledge to DTE (“@00<CR><LF>”).

20 ms toggling on CTS control line needed to acknowledge switching
from Data to Command mode and vice versa.

Note: The powered up radio modem by default goes to Data Mode regardless of DTR
control line polarity.

Switching to Data Mode

• DTE sends the CLI command “DATAMODE<CR><LF>” to the unit.

• Unit answers with Escape-Acknowledge („@00<CR><LF>“) and
immediately goes to datamode, so that the DTE can start sending data
as soon as the Escape-Acknowledge has been received.

• If no valid CLI commands received from DTE within 1 minute, the
unit will automatically switch back to data-mode.

Appendix

UHF RADIO USAGE

Many countries require a license for radio users (such as the United States
of America). Be sure you comply with all local laws while operating a
UHF radio.

Surveying in RTK mode has made UHF the most popular choice for com­munications between base and rover receivers. Know the strengths and
weaknesses of this technology to get the best use out of your receiver.

The quality and strength of the UHF signals translates into range for UHF
communications.

The system’s range will greatly depend on the local conditions. Topography,
local communications and even meteorological conditions play a major
role in the possible range of RTK communications.

If needed, use a scanner to nd clear channels for communication.

SAFETY WARNINGS

Read these instructions.

• Keep these instructions.

• Heed all warnings.

• Follow all instructions.

• Clean only with a damp cloth.

• Do not block any of the ventilation openings. Install in accordance
with the manufacturer’s instructions.

• Do not install near any heat sources such as radiators, heat registers,

stoves, or other apparatus (including ampliers) that produce heat.

• Protect the power cord from being walked on or pinched particularly
