Chapter 1 GENERAL DESCRIPTION 1.1. Physical Interfaces 1.1.1. Serial Data 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. 1.1.2. Power Interface The power interface allows connection to an unregulated DC power source. The DC power source (thirdparty or user supplied) must provide DC power of 4.
General Description Physical Interfaces Antennas 1.1.4. Antennas Antenna type depends on the site requirements, and may be directional or omni-directional. Note that to support 8 miles distance range between Base station and FH915 unit, an antenna mast should elevate the base antenna a minimum of 20 feet above the average level of the terrain. 10 www.javad.
Chapter 2 PRODUCT FEATURES 2.1. Introduction FH915 radio transceiver is designed as universal license-free modem. It uses 902-928 MHz ISM (industrial, scientific and medical) license free USA/Australia band frequency hopping transmission techniques for excellent reliability in noisy plant environments and European CEPT license free 868-870 MHz band, allocated for narrow band telemetry, alarms and data transfer applications.
Product Features Operating at Spread Spectrum Band The setting can be done through the built-in Command Line interface (CLI), or through the configuration and maintenance application software running either on PC – AWLaunch. The diagnostic feature of the FH915 system provides the information to monitor and maintain user’s communications link.
Product Features Modulation Technique Media Access Control (MAC) In 868-870 MHz band the design is based on high-level modulation techniques which include Modulation/ Channel Spacing 12.5 kHz 20 kHz 25 kHz GMSK – Minimal Shift Keying with Gaussian Filtering 4.8 kbps 7.5 kbps 9.6 kbps 4FSK- Four Level Frequency Shift Keying (planned) 15 kbps 19.2 kbps 9.
Product Features Modulation Technique Management Tools 2.3.3. Management Tools The built-in management tools along with AWLaunch (configuration and monitoring software application) will 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 monitor status, alarms and radio performance through the intuitive GUI. 3.
Chapter 3 CONNECTION 3.1. FH915 connection The FH915 connected directly to Evaluation Kit (p/n 99-571010-01) by its 16-Lead Header Connector, ECS Corp., as it shown on the Figure 2-1. Adapter OEM Board to Power Supply 6-20 V DC, 1A to Antenna Figure 3-1. FH915 connected to Evaluation Kit 3.2. Antenna connection The FH915 may be connected to external antenna using TNC to MMCX RA Antenna cable (included in the Kit). 3.3.
Connection Serial RS-232 connection CAUTION: Evaluation Kit provides reverse polarity protection only in voltages range, specified for particular FH915. 3.4. Serial RS-232 connection A standard Null-Modem cable (included in Kit) with DB-9 Female connectors on both ends may be used to connect PC COM_X port with Serial port on adapter. Adapter’s DB-9 male connector external view and pinout is shown on the Figure 3-2. Figure 3-2. DB-9 Male connector Table 3-1.
Chapter 4 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 Software Switching to Maintenance Mode • The Carriage Return/Line Feed (CR/LF, 0x0D/0x0A) is a command delimiter. Command delimiters CR or LF or CR+LF are valid. • 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 Hardware Switching to Maintenance Mode 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.
Command Line Interface Networking Commands CONNECT • 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. 4.2.

Serial Interfacing Commands 4.3.1. DPORT The DPORT is an object that responsible for data port interface configurations like Bit Rate, Flow Control, etc.
Command Line Interface Special Commands ALARM Note: JAVAD GNSS radio modem’s does not support data flow and parity on the maintenance serial port. MPORT operates using 8 bits in one byte fixed (not configurable). The radio modem with none-dedicated maintenance serial port must keep CTS line always active in MPORT mode (DP/MP is low). 4.4. Special Commands 4.4.1. ALARM The ALARM command is intended to set up the alarm indication mode and alarm control lines’ behavior.

Appendix B SPREAD SPECTRUM RADIO USAGE Many countries require a license for radio users. Be sure you comply with all local laws while operating a Spread Spectrum radio. The quality and strength of the Spread Spectrum signals translates into range for Spread Spectrum 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 communications. www.javad.
