IntroductionST20B The ST20B is an ELD device. It is designed to collect data through the vehicle diagnostic connector, and interact with a connected tablet. Please note that this Operation Manual is for the standard model. In case specific requirements are incorporated into this Manual, such a manual applies only for the case. 2. OverviewMain function of device installed on a vehicle is to report vehicle data required for ELD. 2-1. Parameter change Parameters which have already been set on the device can be changed via RS232 connected with PC if a user needs to do so. Some controlling functions can also be implemented in the same way. - 9600bps, No parity, 8bit Data, Stop bit 1 2-2. Features Key features of the ST20B device are as follows: - Power Saving Modes (Power Down Modes) - LED Indicators The LEDs indicate whether or not the CAN communication is available from the vehicle - I/O Lines Device has: 1 Output line1 Input lines1 Ignition Output lineoIgnition status is detected by the CAN data- Upgrading Firmware In case ‘firmware’ of the device has an (some) error(s) or needs to be upgraded to provide the user with newly implemented services, the device can upgrade its internal ROM file by RS232 connection. Over the air (OTA) updates will need to be handled by the device the ST20B is connected to, either a tablet or telematics box. RS232 baud rate is 115200 bps for upgrading firmware.

Power Saving If ST20B can receive vehicle data like as SPEED, RPM and so on via J1939 or J1708 interface, the vehicle is in driving. In this case, ST20B will communicate with the tablet and enable charging the battery of the tablet via RS232 cable. RS232 cable has red colored LED indicator and it will be turned on. If ST20B cannot receive any data from the vehicle over 3 seconds, it is considered that the engine of vehicle is turned off. In this case, ST20B will enter the Low-power mode to prevent exhausting vehicle battery. In the Low-power mode, charging battery and communication will be stopped via RS232 cable. Also, LED indicator of RS232 will be turned off. If ST20B receives vehicle data in Low-power mode, it will do wakeup and restart communication and charging tablet.
