The HPT225BT radio transceiver provides a high-speed Point-to-Point and Point-to-Multipoint wireless
data transfer at up to 38.4 kbps. HPT225BT 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 HPT225BT include data scrambling, frequency hopping, user selectable
transmit output power level, low power consumption sleep modes, autoscannin 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 HPT225BT 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.

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. 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.
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.

COMMAND LINE INTERFACE
The built-in user-friendly Command Line Interface (CLI) allows user to perform a full configuration of
the unit and read the statistics and alarm status. It is the most powerful tool to configure the unit. It makes
changes to all possible settings that system will not be able to determine automatically.
The CLI commands allow user to configure and reconfigure the unit’s settings. The user configuration
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 configuration that is set or modified 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 configuration file.
The CLI commands also provide filing operations, which include:
• Downloading
- Unit’s Configuration files
- Software Images
• Uploading Unit’s Configuration files
• Saving into the configuration files the configuration parameters modified through the CLI.

Command Line Interface Convention
1. Command Line Interface Convention
The following convention is implemented in HPT225BT 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 predefined frame format. The
display frame format is unique for each command supporting “/F” option.

1.1. 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”
20 ms toggling on CTS control line needed to acknowledge switching from Data to Command mode and
vice versa.
28
www.javad.com
Command Line Interface
Command Line Interface Convention
Happy Flow
1. 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).
2. If the unit detects the Escape-Sequence:
• The transmitter continues sending over the air the data received from DTE before EscapeSequence and buffers the data from DTE;
• The Receiver immediately stops forwarding to DTE the data received over the air and buffers it
instead.
3. 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.
4. 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.)
1.2. 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 EscapeAcknowledge to DTE (“@00”).
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.
1.3. Switching to Data Mode
• DTE sends the CLI command “DATAMODE” to the unit.
• Unit answers with Escape-Acknowledge („@00“) 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 C
VHF 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 VHF radio.
Surveying in RTK mode has made VHF 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 VHF signals translates into range for VHF 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 find clear channels for communication.
