Introduction Getting Acquainted 1.6. Literature HPT204BT literature, including manuals and other product information are available on the JAVAD GNSS website (http://www.javad.com): • HPT204BT Operator’s Manual • Functional specifications 1.7. External Antenna (not included) Antenna type depends on the site requirements, and may be directional or omni-directional. Warning: Do not use HPT204BT without antenna to avoid serious damage of your device! 1.8. Storage Precautions 1.
Chapter 2 CONFIGURATION 2.1. Powering HPT204BT To power HPT204BT 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 HPT204BT. 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.
Configuration Antenna Installation Power supply requirements 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.
Configuration Antenna Installation Power supply requirements 4. Place the antenna on the pole.
Configuration Installing ModemVU Power supply requirements 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.
Configuration Connecting HPT204BT and Computer Connecting through serial port 2.4. Connecting HPT204BT and Computer 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.
Configuration Configuring HPT204BT Connecting through Bluetooth® 2.4.3. Connecting through Bluetooth® Note: Do not forget to attach the Bluetooth® antenna to Bluetooth antenna connector on the back panel of the modem.
Configuration Configuring HPT204BT Simplex Protocol 2.5.1. Simplex Protocol When the HPT204BT modem is loaded with special firmware which supports Simplex protocol1, the ModemVU general window will be like below: Figure 2-4. Radio Link tab. Simplex protocol 1. On the Radio Link tab, set the following parameters (Table 2-1) and click Apply. Table 2-1.
Configuration Checking Firmware Version Simplex Protocol Parameter Base Modem Repeater Rover Modem Link Space For both Base and Rover modems the link space must be the same. Forward Error Correction Enable Enable Scrambling Enable Enable 1. In Auto mode rover receives the data from both base transmitter and repeater. The sophisticated algorithm of data receiving allows the modem to eliminate any data doubling. 2. In this mode the incoming data from base transmitter will be ignored. 3.
Configuration Loading New Firmware Simplex Protocol 2.7. Loading New Firmware The modem uses ModemVU to load firmware onto the modem. For more information, refer to the ModemVU Software Manual, available on the JAVAD GNSS website. 1. Download the new firmware package to your computer. 2. Connect your modem and computer, as described in “Connecting HPT204BT and Computer” on page 17. 3. Start ModemVU. Select the HPT204BT and than the COM port and click Ok (see “Configuring HPT204BT” on page 18). 4.
Configuration Bluetooth Configuration Simplex Protocol 2.8. Bluetooth Configuration Bluetooth module of HPT204BT can be configured in the BT tab (Figure 2-7). Figure 2-7. BT tab Use the BT drop down list to switch on/off the module. The PIN code can be inserted in the PIN code field. Click Apply to save settings and apply configurations. 22 www.javad.
Chapter 3 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.
Command Line Interface Command Line Interface Convention 1. Command Line Interface Convention The following convention is implemented in HPT204BT 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).
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.
Command Line Interface Networking Commands 2. Networking Commands 2.1. LINK The LINK command is responsible for configuring radio’s operation mode. It has parameters listed below. Note: In parentheses is shown firmware version, which supports this parameter. If the firmware version is not specified, it means that this parameter is supported in both versions.

Appendix B 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.
