Introduction LMR400 DSP based integrated UHF Modem is the single board OEM wireless transceiver intended for SCADA, outdoor telemetry applications and transmission / receiving of differential corrections and additional information by terrestrial radio channels between two GNSS receivers. LMR400 is a half duplex, UHF Radio Transceiver developed to be integrated in a new JAVAD GNSS Receiver (TRIUMPH). It takes incoming data from a JAVAD GNSS receiver through the standard asynchronous serial port (CMOS/ TTL compatible), modulates it with GMSK, FSK, PSK or most spectrum efficient QAM modulation and transmits it at RF power output levels from 15 dBm up to 30 dBm operating in UHF frequency band (406.1 to 470 MHz). Figure 1-1. LMR400 The UHF transceiver is also capable of receiving RF signals through a 50 Ohm impedance external antenna port. These signals are demodulated and output to the JAVAD GNSS receiver. LMR400 delivers a reliable radio link at up to 38.4 kbps over the air for the 25 kHz channel spacing, 19.2 kbps for 12.5 kHz, and 9.6 kbps for 6.25 kHz. www.javad.com 13 The module requires a regulated DC voltage power supply 4.2 V ± 5 %. The delivered product is a wireless system, which includes: • LMR400 – UHF Radio Transceiver; • “JRadio” – Windows based Unit Configuration and Maintenance Software Application running on a IBM PC compatible computer and connecting to the device over RS-232 interface. The unit’s user settings can be changed through the built-in Command Line interface (CLI), or through JRadio. The system built-in diagnostic features provide the information required to monitor and maintain user’s communications link. The output transmit power, receive signal strength (RSSI), antenna/feed line condition, and data decode performance will be transmitted online without application interruption. The product is designed for maximum performance and reliability even in the harshest environments. Plug and play at its best, robust, withstanding the most adverse of conditions. 1.2. Operating at Ultra High Frequency Band LMR400 operates in UHF frequency band covering both licensed and unlicensed frequencies. The following are its key benefits: 1. Operating in UHF frequency band will provide a non-line of sight connection. 2. User selectable operation mode (licensed or unlicensed mode) is a feature, which makes JAVAD GNSS’s radio modems suitable for both licensed and unlicensed markets. 3. Relatively low cost associated with installation equipment compared to the licensed wireless bands, since no capital is required to purchase spectrum rights. 4. User-selectable channel spacing (25/12.5/6.25 kHz) is a feature, which makes LMR400 modems attractive for distributors and system integrators. www.javad.com Product Features Modulation Technique 1.3. Modulation Technique The design will be based on high-level modulation techniques which include: 6.25 kHz 12.5 kHz 25 kHz DBPSK – Differential Binary Phase Shift Keying 2.4 kbps 4.8 kbps 9.6 kbps DQPSK – Differential Quadrature Phase Shift Keying 4.8 kbps 9.6 kbps 19.2 kbps D8PSK – Eight Phase Shift Keying 7.2 kbps 14.4 kbps 28.8 kbps D16QAM – Sixteen Quadrature Amplitude Modulation 9.6 kbps 19.2 kbps 38.4 kbps GMSK – Minimal Shift Keying with Gaussian Filtering N\A* *. N/A – Not Applicable 4.8 kbps 9.6 kbps The following are its key benefits: 1. Provides an excellent spectral efficiency (up to 2.3 bps/Hz for D16QAM), it is better than any product available on the market. 2. Forward Error Correction scheme (FEC) is based on Hamming Code known as a Perfect Code. Although Hamming Code is not very powerful, it is easy to implement and does not require much DSP resources. 3. More powerful Reed-Solomon FEC coding scheme improves the tolerance to interference and ensures the highest link quality at distances range higher than 15 miles (24 km) and roaming speeds of up to 60 mph (96 km/h). 1.4. Network Topologies LMR400 is developed to support Point-to-Point link (PTP) using Time Division Duplex (TDD) protocol and Point-to-Multipoint (PMP) network topology using Time Division Multiple Access (TDMA) protocol. The media access contention between wireless nodes in PMP network (Remotes) can be resolved by an external controller (TRIUMPH GNSS Receiver) located on base station (Base). The CONNECT command is intended to establish the link with a specific Remote. The RTS and CTS data flow control lines (Request-To-Send and Clear-To-Send) can be used on Remote side to support TDMA protocol implementation. www.javad.com 15 Product Features Operating Modes 1.5. Operating Modes The operating modes for LMR400 can be set through the CLI, or through JRadio. The following operating modes are available for LMR400: 1. Simplex operating modes (Simplex Base, Remote and Repeater) are developed primarily for GNSS applications. 2. Half Duplex Base, Remote and Repeater are the alternative to Simplex operating modes that are implemented based on half-duplex TDD protocol with dynamic bandwidth allocation. 3. Sleep mode has automatic transmitter activation by an internal real-time clock, or by an external controller through the data interface control lines (RTS). 4. The programmable automatic channel scanning of the Preferred Channels is an alternative mode to the operation on the fixed Frequency Channel. In this mode, the Base is looking for a “free of use” frequency channel while a Remote is looking for a Base to interact with. 5. Test mode supports the radio installation using Built-in test tools. 1.6. Management Tools The built-in management tools along with JRadio running on PC compatible computer provide the following benefits: 1. Easy user’s interface for system configuration and monitoring using well developed CLI or intuitive GUI. 2. An ability to test the link using built-in test utilities without expensive external test equipment such as spectrum analyzer and BER test analyzer. 3. An ability to monitor status, alarms and radio performance through the intuitive GUI. 4. LMR400 firmware upgrades and improvements can be downloaded to the units over serial link locally or over-the-air remotely. Note: Downloading over-the-air remotely is not requested by JAVAD GNSS for first release. 1.7. Security The system will provide wireless media access protection as well as data encryption. The following are its key features and benefits: 16 www.javad.com Product Features Security 1. The Key Sequence generated by Pseudo-random generator scrambles the fully formatted frame (including Frame’s CRC). This provides the wireless media access protection. 2. User selectable Frequency Hopping Pattern provides another level of the wireless media access protection. At the same time it allows operators to increase the number of links deployed in the same location. www.javad.com 17 Product Features Security 18 www.javad.com Chapter 2 GENERAL DESCRIPTION 2.1. Hardware Platform UHF module electronic hardware consists of Zero-IF RF Front-End and Digital Section based on BlackFin DSP micro processor. Both are located on a single PCB board.

Physical Interfaces 2.2.1. Serial Data/Command Interface The serial asynchronous interface allows connection to external serial devices. It is shared between user data and unit’s command/status information. All commonly supported baud rates, parity and bit configurations are available up to 115.2 kbps for UART. www.javad.com 19 2.2.2. RF Interface RF interface is a 50-ohm impedance matched standard MMCX connector as required by regulation. The RF interface can operate without damage to the unit under DC short and open conditions. The RF interface is protected against static discharge (15 kV air discharge, 8 kV contact discharge) and unloaded output. Switching from UHF module to cell module operation mode and vice versa is provided on RF interface in case if they share the same antenna. 2.2.3. Antennas Antenna type depends on the site requirements, and may be directional or omni-directional. The antenna must have a 50-ohm impedance matched interface with VSWR 2.0:1 or better. The Base transceiver is recommended to be mounted on an antenna mast that elevates the antenna a minimum of 40 feet above the average level of the terrain to support 15 miles distance range. 2.2.4. Power Interface The power interface allows connection to an unregulated DC power source. The DC power source (thirdparty or user supplied) must provide peak 7.5 W of DC power 4.2 V ± 5 %. www.javad.com 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. 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 See “Network Topologies” on page 15 for details. • 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 www.javad.com 21 Command Line Interface Command Line Interface Convention Software Switching to Maintenance Mode • Saving into the configuration files the configuration parameters modified through the CLI. 3.1. Command Line Interface Convention The following convention is implemented in AW400Tx 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 1 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. Table 1. Command Line Interface Error Codes Error Code Short Description 0x01 Command Syntax Error. A command followed by “/?” displays a command usage. 0x02 The parameter has a format error. A command with the certain [Parameter Name] followed by “/?” displays the format and range of the variable. 0x03 The parameter is out of allowed range. A command with the certain [Parameter Name] followed by “/?” displays the format and range of the variable. 0x04 The command is not valid for specific radio model. To display the list of available commands, the HELP command must be used (see “Software Switching to Maintenance Mode” ). 0x05 Unspecified Error 3.1.1. Software Switching to Maintenance Mode Software Switching to Maintenance Mode can be utilized if Data/Maintenance Port (DP/MP) control line is set to High Z (or 3.3v) level. To switch to Maintenance mode the special bytesequences with special meanings are used: 22 www.javad.com Command Line Interface Command Line Interface Convention Hardware Switching to Maintenance Mode • Escape-Sequence: “+++”or “++++” 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 Maintenance mode and vice versa. In Maintenance mode, the unit’s serial port must keep CTS line always active (see also “MPORT” on page 27). Note: “++++”used for Topcon products only. Happy Flow 1. In data-mode the unit starts looking for the Escape-sequence if there is no data from DTE 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 Maintenance 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.) 3.1.2. Hardware Switching to Maintenance Mode As alternative to Software Switching, the switching through the MP/DP control line can be used (this control line can be also used as Data Terminal Ready, DTR). To set Maintenance mode, the www.javad.com 23 Command Line Interface Networking Commands Switching to Data Mode DTE must assert DTR signal active (0v level). By falling edge of DTR signal the unit goes to Maintenance mode and then sends Escape-Acknowledge to DTE („@00 “). 20 ms toggling on CTS control line followed by Escape-Acknowledge response is needed to acknowledge switching from Data to Maintenance mode and vice versa. In Maintenance Mode, the unit’s serial port must keep Clear to Send (CTS) line always active (see also “MPORT” on page 27). Note: The powered up radio modem by default goes to Data Mode regardless of DTR control line polarity. 3.1.3. 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. Note: The data received over the air could be lost due to Rx buffer overflow if the unit stays in Maintenance mode longer then 15 second. 3.2. Networking Commands 3.2.1. CONNECT To connect the radio unit through the local maintenance serial port or to establish the link with the remote unit in the Point-to-Multipoint network, the CONNECT command must be used. CONNECT [Unit_Numb] [/?] Where the Unit_Numb is an assigned decimal number for the unit to be connected. To get the complete unit list, the CONNECT command must be used with no parameter. The list of units in the Point-to-Point link with the connection established with remote unit is shown in Figure 3-1: Unit Serial Number BS 003578659922 003574459923 Connect Figure 3-1. Connection List 24 www.javad.com Command Line Interface Networking Commands LINK To connect to the Base unit, through the remote unit, the parameter (Unit_Numb) must be equal to 0. To connect the local unit (Base or Remote), the parameter (Unit_Numb) must be equal to 0xFF. 3.2.2. LINK The LINK command is responsible for configuring radio’s operation mode.
