The features supported include the following. GPS The major functionality of the GPS module is to compute the correlation results between the incoming signal and the selected PRN code based on certain Carrier Doppler Frequency, Code Doppler Frequency, code phase, carrier phase, and the particular satellite the module is tracking or acquiring. GPIO
New Product Requirement Asiatelco Technologies Co. Proprietary/Confidential Two GPIO pins, GP1 and GP2, are presented to the external environment on the main connector. They are general purpose bidirectional lines capable of providing system interrupts to generate a report or drive logic levels to external devices. These lines are 2.8V logic level and are 15V tolerant. These pins default to input. GP1 is pulled down representing 0 when disconnected; GP2 is pulled up representing logical 1 when disconnected. They should be asserted to a known value if used. GP1 is intended to use for Ignition Sensing. LED’s Two LED status indicators are provided to verify correct installation and operation. The status LEDs are color coded and directly convey the status of the CDMA and GPS subsystems as described in the table below. Their valid operation also indicates operational status and power. LED Function Status Red GPS On: GPS satellites acquired and Locked Flash Slow: GPS satellite search is in progress Off: No power or GPS subsystem fault Green CDMA/CDMA Connection On: Indicates CDMA connection is made Flash Slow: CDMA subsystem initialized but no connection Flash Fast: CDMA initialization in process Off: No power or CDMA subsystem fault The ION provides user control allowing the LEDs to be extinguished once installation is verified. This feature reduces power and further conceals the ION Tracker from untrained parties wishing to defeat its operation. UART A UART port is provided for AT command and data interaction and optionally for application specific control. When in power down mode, a character must be sent to the UART first to wake it up. The port will stay awake for 5 seconds after any character received. Relay Driver A 500mA sink capable output pin is provided. This pin is meant to drive a relay coil indented to interrupt the starter solenoid relay for the ignition circuit to a car. Battery Monitor The battery monitor is internal analog input scaled such that the DC value of the power input pin to the ION system is measured. This value is scaled to span the most significant 8 bits of the A/D and consequently covers a scale from 0 to 25.5 Volts. Timers Timers resident on the CDMA baseband chip generate periodic interrupts for power down wakeup, watchdog support, report generation and other timer related functions. Report timers are supported by related AT command and cause generation of periodic reports.
New Product Requirement Asiatelco Technologies Co. Proprietary/Confidential Watchdog CBP8.2 chipset provide internal software Watchdog, and a physically dedicate Watchdog circuit requirement is optional. Motion Detect (Option) A factory populates option for motion detector is provided. If populated at the time the MC891G is manufactured, this option will work with firmware power down options to keep the MC891G in a very low power down state until motion is detected. Upon wakening, a report can then be generated. 3.2 Basic RF Performance Requirements Items Requirements Remark TRP free space >= 20 dBm TRP free space TIS free space <= -104dBm TIS free space Antenna loss <= -3 dB TRP-TX Power Conducted Antenna Loss <= -3 dB RX receive sensitivity conducted – TIS Board RF SpecificationCellular Band RX Frequency range 869MHz～894MHz Sensitivity -108dBm (FER≤0.5%) Dynamic range -25～-108dBm (FER≤0.5%) Single tone Desensitization -102.4dBm(FER≤1%,-30dBm@±900KHz) Intermediation Spurious Response Attenuation -102.4dBm(FER≤1%,-43dBm@±900 KHz/±1700KHz) -91.4dBm(FER≤1%,-32dBm @±900 KHz/±1700KHz) -80.4dBm(FER≤1%,-21dBm @±900 KHz/±1700KHz) Conducted Spurious Emission <-76dBm/1MHz（RX band） <-61dBm/1MHz（ TX band） <-47dBm/30KHz（other frequency） Cellular Band TX Frequency range 824MHz～849MHz Maximum Frequency error ±300KHz Maximum output power 24dBm [-3dB~~+2dB] ; Minimum controlled output power <-50dBm Standby output power <-61dBm Code domain power The code domain power in each inactive code channel shall be 23 dB or more below the total output power measured on both the I and Q data channel combined.

An over the air TFTP (Trivial File Transfer Protocol) connection is made over a UDP/IP connection. A replacement file is then transferred from a server to the MC891G and that file replaces the previous application image. 4.2.1 Auto Execute The Auto Execute Utility copies the contents of file system.exf into system executable RAM and executes it from there. This file is the factory default application. Another file named custom.exf can be loaded into the file system. Auto Execute will look first for a file named update.exf and load and execute that in place of custom.exf if it exists. If update.exf executes successfully, the previous copy of custom.exf is deleted from the file system and update.exf is renamed to custom.exf. 4.3 Power Modes The MC891G device supports several power modes that are set by the power mode command. In full power mode the cellular subsystem will maintain a persistent cellular connection whenever service is available as well as an IP connection where available. Any hardware or software reset will interrupt any power mode and return the device to full power mode. In summary, the conditions permanently restoring full power mode include:
New Product Requirement Asiatelco Technologies Co. Proprietary/Confidential Power cycleWatchdog timeoutReset commandCDMA phone call resetSMS or UART power mode commandMotion detect (if detector installed and enabled)When in a power down mode, the following resources will cause interrupts that will wake the MC891G and cause it to attempt complete the function associated with the interrupt. Simultaneous interrupts will cause sequential completion of each associated function. These interrupts include:   Report timer   GPIO change   Battery threshold   Heartbeat   Watchdog   Power-up The related interrupt function will be attempted for a total duration set the associated parameter in the power mode command. 4.4 AT Command MC891G commands are AT extensions specific to MC891G devices. They are closely based on commands that are as similar as possible to other industry common devices and are essentially subsets of standard ION commands. Common commands used with CDMA modems supporting IP connectivity are not included within the MC891G command set extensions. These commands are left in their native structure, as defined by the respective baseband CDMA chip supplier which product already in use. Command Summary The following commands are highly specialized to the MC891G. The commands listed are intended to be similar to counterparts found in common CDMA modem command extension. 1.

AT+IONVTO: Virtual Trip Odometer 4.5 Report The MC891G captures data and forms a report record with that data. This is a single data structure intended to contain all of the typically useful data on the MC891G. Other information can be queried separately using separate AT commands. Reports are always generated by interrupts regardless of whether or not there is a GPS lock. If no lock has ever been attained since hardware reset, default values of 0 are returned for all GPS fields. If a lock has been attained and lost, the report will contain the last valid GPS data including the timestamp of that data. Base Requirements： 1. A report is generated in response to either an interrupt event or in response to execution of associated AT commands explicitly requesting one. 2. GPS coordinates are stored in reports as signed hex values to save space. 3. To reduce data transmission costs, the data within a report record can be masked and removed before it is transmitted. 4. Every report has a tag and each enabled interrupt or event generates a separate report. The report tags indicate the cause of the generated report, which can be an interrupt, an event or in response to a command. 4.6 Reset There is an internal soft reset. 4.6.1 Context Preservation When a reset is caused by the Network Watchdog or by the Reset command (modes 0,1), the context of the system is being preserved and is restored after the reset. The context includes all the periodic timers, the report queue, the odometer, etc. This allows to reset the unit as a troubleshooting measure either periodically or due to Network Watchdog without losing reports that are already in the queue or are pending on running timers. Note that the reset process may cause 1-2min of inaccuracy in the timers and should not be considered as very precise. Modes 8/9 of the IONRS command perform soft and hard reset respectively without preserving any context. Factory reset (IONFR) also does not preserve any context of the system. 4.7 Startup Banner After a reset a startup banner is printed through the UART only. The format and content of the banner shown below: FW:<firmware version>; BIN:<bin version>; MEID/ESN:<MEID/ESN> APN1:<apn1 name>; IP:<IP>:<port>;LPORT:<lport> RI:<s,v,t>; DTE:<t1,t2,t3>; DI:<t>; HB:<t>; NR:<t,c,r>; RS:<a,t,r>
