User Manual 1. Purpose and Scope of Document The purpose of this document is to provide the user with instructions on how to properly operate the RF Sniffer. 2. Overview of the RF Sniffer The RF Sniffer is a 900MHz frequency-hopping self-contained deployment tool which provides a link between a device running specially designed software and the mesh network. It communicates via the 900 MHz Spread Spectrum mesh network and connects to a personal computer or PDA USB port.
User Manual 2.1 Operation To use the RF Sniffer one only needs a connection to a USB port (PDA or PC). For limited periods of time the device can operate just by the internal Li-Ion rechargeable battery. When the device is not in use the power should be turned off to the device, then plugged into the AC Adapter for charging. There are 3 visual indicators (LED’s) on the front panel: Proprietary & Confidential Page 2 version 1.
User Manual GREEN LED - Battery Charging LED indicator, continuously light, for periods that the device is charging the internal battery. RED LED – Power LED indicator, continuously light if power on and the battery is charged enough. As soon as the battery is depleted and need recharging the LED start FLASHING.
User Manual . On the top side of the board (pictured above) you will find the RF components, (underneath the RF shield), the power supply section and the PCB antenna. The opposite side of the board contains the microcontroller and digital section as can be seen in the picture below. Proprietary & Confidential Page 4 version 1.
User Manual The JTAG connector is located below and to the right of the RF shield on the front side of the circuit board. This is used for production and debugging purposes, loading firmware etc. Proprietary & Confidential Page 5 version 1.
User Manual 2.1.1 USB Interface block The USB interface uses a serial to USB bridge controller. Device conforms to USB 2.0 standard. This chip is responsible for translating the USB protocol to the serial protocol used by the microcontroller. Connection to the PC is via a standard USB Mini B connector. The circuit is protected from damaging ESD by using a quad transient voltage suppressor. The USB interface also provides 5 volts for charging the internal Li-In battery. 2.1.
User Manual always charge from the AC adapter, whether the Sniffer is on or off. The units are supplied from the factory with the jumper installed. The green LED shows the charging status and is controlled by charging hardware. It is normal for the LED to cycle on and off if the Sniffer is idle for some time and the battery is fully charged. 2.1.3 Buck / Boost Regulator block The power supply blocks uses a switch-mode regulator circuit which operates as a buck / boost regulator.
User Manual RF section: - includes RF transceiver, RF Power amplifier, Antenna Tx/Rx Switch 3. Diagnostic Software The NivisLink application was developed in order to exercise the features of the Nivis Radio modem. The NivisLink application is a software application composed of a firmware hex file which is to be loaded onto the Sniffer and a GUI that controls various features of the modem. 3.1. Getting started 3.1.1 Prerequisites Install the Silicon Laboratories USB bridge drivers for CP2102 on the PC.
User Manual 3.2 Read Calibration EEPROM Note: The following procedure assumes that the RF Sniffer used has already undergone the calibration procedure. For tune-up and calibration procedure consult the “Tune-up Procedure” document. The SN, DNA, PA Max level, temperature sensor calibration value and other calibration data necessary for the operation of the RF Sniffer is stored in the calibration EEPROM. Proprietary & Confidential Page 9 version 1.
User Manual By pressing the “READ I2S” button the content of the calibration EEPROM is displayed in the tabs provided for various parameters. The following parameters will be displayed • Serial Number – unique identifying ID of the Sniffer • DNA – network identification number • Power Amplifier max level – maximum value of the power amplifier gain • Firmware version 3.3 Transmission In order to set the RF Sniffer in transmit mode the “SET TX MODE” button must be employed.
User Manual The NivisLink application also gives the user the flexibility to directly control the functional registers of the RF transceiver. This gives the user complete control over every aspect of the RF functionality of the RF Sniffer. These register should only be overwritten by users that are knowledgeable of the RF transceiver. For a list and explanation of each RF register consult the datasheet of the RF transceiver. 3.
User Manual This Device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference received, including interference that may cause undesired operation. 6. Information to the User (Part 15.105) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
