1. General characteristics

1.1 About

Tytan®SAT DS520 is GSM/GPRS device designed for real time tracking of vehicles and cargo or

supervising technical objects. Device transmits location data (GPS/GLONASS position and speed) with

current parameters and events registered in monitored objects to the external server using UDP or TCP

protocol.

Due to analogue/digital inputs and 1-wire interface the device: a) measures data from sensors with

analogue output signal (e.g. from fuel level sensors), b) authorises access to the vehicle via iButton

identifiers, c) measures temperature via 1-wire sensors, d) monitors status of up to 5 switches (vehicle’s

door and bonnet/tailgate). Due to digital outputs the device allows users to control 2 circuits remotely.

The device is supplied with non-volatile memory which prevents data loss in case of no GSM network

coverage. In such cases, data are stored in non-volatile memory. Once connection is retrieved, data are

re-sent to the server.

DS520B version is equipped with internal LiPo battery. It allows the device to operate in emergency

conditions when power supply is lost.

1.2 Basic characteristics

•Power supply 12V/24V (voltage range 8-40V).

•Power consumption: average 14-36 mA (depending on configuration of transmission

intervals).

•Power saving modes: GPS sleep and deepsleep –min. power consumption less than 2mA.

•Additional 350mAh LiPo battery (available only in DS520B version).

•Up to 24h (conditions dependent) of operation without power supply (only DS520B).

•2 analogue inputs AI0/AI1, 0-10V/0-30V.

•4 digital inputs DI2/DI3/DI4/DI5.

•2 digital outputs OUT0/OUT1 (OC type).

•Built-in 3-axe accelerometer to detect drive condition without connecting ignition circuit.

•1-wire interface: iButton identifiers (DS1990A) and DS18B20 digital temperature sensors.

•List of up to 500 authorised iButton identifiers.

•Immobiliser function.

•Quad-band GSM/GPRS modem Simcomm SIM800C.

•External GSM antenna.

•Built-in GPS/GLONASS receiver Tytan Digital Systems GPS/GLONASS 1537 with

simultaneous observation of GPS and GLONASS satellites.

•External GPS/GLONASS antenna.

•32-bit Microchip MX7 microcontroller, 512kB Flash ROM, 128kB RAM.

•Built-in 4Mb memory to store data. Capacity: up to 50000 reports.

•Remote configuration and firmware upgrades via GSM/GPRS using FTP protocol.

•Two LEDs signalling device operation.

•USB port for configuration and device diagnostics.

1.5 Functionality

Data

transmission

Sending vehicle data via GPRS using UDP or TCP protocol in GSM network.

Limiting data transfer by collecting larger amount of data into packets.

Telemetry

Data collection from GPS/GLONASS satellite navigation systems,

analogue/digital inputs and 1-wire interface.

Vehicle location

Real-time transmission of vehicle geoposition, sampling grid dependent on

time, distance and vehicle heading angle.

Vehicle mileage

Mileage calculated by the device on the basis of GPS coordinates, regardless of

density of sampling positions. It is calculated incrementally among reports or

globally for one journey.

Roaming

Separate reporting configurations for operation in GSM home network and

roaming (intelligent roaming). Current country code and network provider name

are transmitted to the server.

Event log

memory

Data storage in non-volatile memory –prevents data loss in case of no GSM

coverage (once coverage is retrieved, data stored in memory is re-sent to the

server). Up to 50000 reports can be stored in memory (~85 hours of work with

10 reports generated every minute).

Remote firmware

upgrades

Remote firmware upgrades via GSM/GPRS - OTA (over-the-air) using FTP

protocol. Upgrade control via GPRS or SMS commands.

Remote

configuration

upgrades

Remote configuration reading and writing via GSM/GPRS - OTA (over-the-air)

using FTP protocol. Configuration reading and writing control via GPRS or SMS

commands.

Fuel

Fuel level readouts from two fuel level sensor circuits (OEM float type sensors

and FLS with analogue output 0-10V).

Driver’s

identification

Optional driver’s identification using iButtons (DS1990A).

Immobiliser

Optional immobiliser function that prevents unauthorised starting of the vehicle

engine.

Installation

Low power consumption and compact easy to install housing.

Optional simplified installation (power supply only, no ignition signal).

Virtual ignition

signal

Drive signal detection from readouts of both vehicle acceleration and vibration

and/or power voltage changes.

Device

diagnostics

Advanced diagnostic tools for PC use, improving device installation and start-up.

Internal battery

Device emergency operation in case of power supply lost. Depending on

configuration and conditions: from several minutes up to 24h.
