`
`Geotab’s GO telematics device is a world first expandable plug-&-play telematics technology.Initial production of the Geotab GO1
`device began in 1997. Since then, Geotab has continued to modify and enhance various aspects of the device, and has most
`recently released the GO7 model. The original GO1 device’s main features included GPS recording and key downloading, which can
`be comparedto today’s live stream GPS tracking with engine diagnostics, as well as moreinterfaces and functions. Geotab continues
`to work to meetthe diversified demands of Fleet Managers from around the world.
`
`Geotab GO1 Telematics Device
`
`The original GO device was a 4 x 3 x 1.5 inch box, which recorded vehicle GPS data. Customers could download the GPS data
`through a “key”that connected to the device. The firmware was running on PIC16 at 4MIPS, which wassufficient for storing limited
`data at that time.

`
`Geotab GO2
`
`In 2002, the Geotab GO2 fleet management device was introduced to the market with strengthened data collection, including radio
`frequency (RF) download andlive tracking. The GO2-KEY improved the key download speed - it was within 20 seconds as opposed
`
`2
`
`

`

`to counting by minutes. GO2-RF integrated an RF module, which could wirelessly transfer the data to the database when the vehicle
`passed within fairly close proximity to an RF receiver. Live tracking was also available by connecting an add-on modem to the GO
`device. GO-LIVE allowed the customer to accessthe real time vehicle data. While the live method is the most convenient, cellular
`data costs werefairly high at that time so sending the data through air was not very popular in the market. The printed circuit board
`(PCB) size was the same as the GO1, but the device was larger to improve the wiring stability. The multiple control unit (MCU) was
`upgraded to PIC18 at 10MIPS and the data FLASH wasenlarged to 8MB in order to support the added functions.

`In addition, GPS data was nolonger the only information that the GO device wascollecting. Auxiliary inputs were introduced to
`monitor part of ON/OFFstatusof vehicle circuitry, and the vehicle ignition on could also be detected. Another new feature was the
`addition of the Relay Control Ability. The GO2 could store 20, 000 records, which meant that more than 2 days of data could be
`saved inside the device when sampling every 10 seconds.
`
`A sub-version of the GO2 called the GO2-J1708 (supported J1708 interface) allowed the engine data to be recorded. The data

`eotab GO3
`
`The GO3 was released in 2006 to support more functions such as J1939 (CAN bus) and WIFI. On the engine side, J1708 supports
`RS485 for legacy vehicle while J1939 supports CAN standard, which was becoming more popular around this time. Multiple
`download accesses including RF and WIFI were provided. The MCU was upgraded to PIC24 running at 20MIPS while data FLASH was
`enlarged to 32MB.

`Geotab GO4
`
`The GO4 was a superior upgrade from earlier versions. A unique aspect of this model was the fact that the cellular modem was
`designed inside the device. An integrated and switchable modem allowed Geotab’s system to be more robust than previous versions.

`
`

`

`J1850 and ISO K&L Line were introduced with the GO4. Main MCU PIC24 was running at 20MIPS and a second PIC24 at 16MIPS was
`dedicated to control the peripheral interface to improve system stability.
`
`The GO4 wentthrough threedifferent versions. V1 and V2 were released in the same year as the GO3, while V3 was launched three
`years later. V1 supported J1708 standard for engine communication. The automotive legacy protocols and J1939 CAN were
`introduced in V2. Both these elements as well as J1708 were applied in three separate boards.
`
`In the GO4V3, J1708, J1939 and automotive legacy circuitry were integrated in one board to provide optimal flexibility for

`
`eotab GO5
`
`In an effort to improve the overall plug-&-play customer experience, Geotab developed a compact size GO device in 2010 which was
`small enough to fit in the palm of your hand. The GOS5 wasa streamlined, compact version of the GO4V3 functionality with no
`auxiliaries. It was 1 x 2 x 3 inchesin size with GPS/Cellular antennas and a buzzer. The GO5 could be pluggedinto the vehicle OBDII
`connector directly, which saved the installation effort and shortened theinstallation time from minutes to seconds. By working at
`20MIPS, PIC24 MCU collects engine data from CAN, J1850 or ISO K&LLine, acquiring GPS and acceleration information, and then
`transferring the data to the database through GSM or 3G network.

`The small form factor and powerful functions of the GO5 wereattractive to many, but a number of customersstill required

`Geotab GO7
`
`The Geotab GO7 was broughtto the market in 2014. This unit is more affordable and allows for increased automotive protocol
`expansion. In addition to the standard CAN bus, the Mid-Speed CAN and Single Wire CAN are supportedfor legacy vehicle. There
`are also four Manufacturer Discretion Interfaces, which could be configured in firmwareto fit different custom peripherals. PIC33
