User Manual Wireless Communication Device SIMBA2 CAT-M May 07, 2020 1 1 Introduction The device comes pre-configured from the factory. It is ready to use. The SIMBA appears to a user or a server application as an endpoint device. It can be queried, updated and configured either through a serial connection, an over the air IP connection, or through SMS messaging. The SIMBA presents itself over these connections as an enhanced cellular modem with attached functional elements. These elements include:
Input/outputs dedicated for ignition, relay, buzzer, and general purpose GPS location engine Accelerometer Serial UART port Timers Watchdog lockup protection Power management Event reporting Voltage monitoring Access to these elements and general purpose interface is done through an extended AT command set. Configuration parameters are stored to flash memory and are automatically used on the next power up event. For more details, please reference the AT Command document. 2 Hardware Design 2.1 Basic Hardware Items Requirement 2 Cellular Modem Cellular Antenna GPS Antenna UIM requirement Based on Quectel BG96 Module Internal single antenna Dedicate high performance ceramic antenna Support No SupportHot Plug/Unplug 3FF SIM Interrupt Mode Battery Monitor Build in battery manager Interface Internal analog input Yes Debug UART 12V DC Input Ground Relay Drive (Open Drain , 500mA current) Dedicated Output for buzzer control Ignition Input GPIO Yes External HW via MCU SupportedGPS/G-Sensor 3 LED Supported 1- RED; 1- Green;1-Orange 2-

< 5Watts The SIMBA provides support for specialized hardware features through extended AT commands. The features supported include the following:
Accelerometer The accelerometer can be used for motion detection and driver behavior monitoring. 3 The SIMBA supports OTA field upgrades of the resident application. An over the air FTP connection is made over an IP connection. A replacement file is then transferred from a server to the SIMBA and that file replaces the previous application image. 3.2 Remote Update 3.3 Power Modes The SIMBA device supports several power modes that are set by AT commands. In full power mode the GPS is active and the cellular subsystem will maintain a persistent cellular connection whenever service is available. IP connection is maintained according to the configuration of the device. The device can be put in low power mode whenever it runs on a backup battery or if the external battery is low or if it is not moving. In low power mode the GPS is not running and the LEDs are off. The device would return to full power whenever an event occurs that triggers a report. Those events include:
Periodic report IP change Battery threshold GPIO change Heartbeat Watchdog Power-up Ignition Trip start and stop Any hardware or software reset will return the device to full power mode. 4 4 Test Method 4.1 Hardware Test Item Description Baseband Function Test Power Input Test Power Consumption and Current Test Heat Dissipation Test UART Stability Test GPIO Level Test LED Stability Test Drop Down Test ESD Test High/Low Temperature Test Humidity Test RF Performance Test GPS Performance Test Antenna Performance Test RF Test 4.2 Software Test Test Environment Construct Message Test environment 1.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help. 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, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 7 RF Exposure Information This device meets the governments requirements for exposure to radio waves. This device is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the U.S. Government. This device complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall not be less than 20cm (8 inches) during normal operation. ISED Notice This device complies with Innovation, Science and Economic Development Canada license-exempt RSS standard(s). Operation is subject to the following two conditions:
(1) this device may not cause interference, and
(2) this device must accept any interference, including interference that may cause undesired operation of the device. Le prsent appareil est conforme aux CNR Innovation, Sciences et Dveloppement conomique Canada applicables aux appareils radio exempts de licence. L'exploitation est autorise aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible d'en This device complies with the Canadian ICES-003 Class B specifications. CAN ICES-3(B)/ NMB-3(B) IC: 22952-FLF2M ISED RF Exposure Statement This device complies with ISED RSS-102 RF exposure limits set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the IC RSS-102 RF exposure limits, human proximity to the antenna shall not be less than 20cm (8 inches) during normal operation. Cet appareil est conforme aux limites d'exposition aux rayonnements de la CNR-102 dfinies pour un environnement non contrl. Afin d'viter la possibilit de dpasser les limites d'exposition aux frquences radio de la CNR-102, la proximit humaine l'antenne ne doit pas tre infrieure 20 cm (8 pouces) pendant le fonctionnement normal.
