1.3 Safety Precautions

Safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal from HCP d.o.o.

Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the product. HCP d.o.o assumes no liability for customer’s failure to comply with these precautions.

When in hospitals or other health care facilities, observe the restrictions on the use of mobiles. Switch off the cellular terminal or mobile if to be instructed to do so by the guidelines posted in sensitive areas. Medical equipment may be sensitive to RF energy. The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be affected by interference from cellular terminals or mobiles placed close to the device. If in doubt about potential danger, contact the physician or the manufacturer of the device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep their hand-held mobile away from the pacemaker, while it is on. This personal subgroup always should check the distance to the mobile

Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it cannot be switched on inadvertently. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communications systems. Failure to observe these instructions may lead to the suspension or denial of cellular services to the offender, legal action, or both. Check the local and actual laws about these themes.

Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard.

Your cellular terminal or mobile receives and transmits radio frequency energy while switched on. Remember that interference can occur if it is used close to TV sets,radios, computers or inadequ- ately shielded equipment. Follow any special regulations and always switch off the cellular terminal or mobile wherever forbidden, or when you suspect that it may cause interference or danger.

Road safety comes first! Do not use a hand-held cellular terminal or mobile while driving a vehicle unless it is securely mounted in a holder for speakerphone operation. Before making a call with a hand-held terminal or mobile park the vehicle. Speakerphones must be installed by qualified personnel. Faulty installation or operation can constitute a safety hazard. Check the actual and local laws about these themes.

IMPORTANT! Cellular terminals or mobiles operate using radio signals and cellular networks. In that case connections cannot be guaranteed at all times under all conditions. Therefore, you should never rely solely upon any wireless device for essential communications, for example emergency calls. Remember, in order to make calls or receive calls the cellular terminal or mobile must be switched on in a service area with adequate cellular signal strength. Some networks do not allow for emergency calls if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may need to deactivate those features before you can make an emergency call. Some networks require a valid SIM card to be properly inserted in the cellular terminal or mobile.

If a power supply unit is used to supply the device it must meet the demands placed on SELV circuits in accordance with EN60950. The maximum permissible connection length between the device and the supply source should not exceed 3m.

According to the guidelines for human exposure to radio frequency energy, an antenna connected to the FME jack of the device should be placed at least 20cm away from human bodies.

TC65i Power/GPIO connector Parameters ASC0 – Rx0,Tx0 --- Communication with external device ASC1 – Rx1,Tx1 --- Communication between GSM and GPS module

GPIO1 DI_1 Digital input 1 GPIO2 DI_2 Digital input 2 GPIO3 DI_3 Digital input 3

GPIO4/GPIO10* DI_4 Digital input 4 (pulse counter) GPIO5 DO_1 Digital output 1 GPIO6 -- Reset GPS modem GPIO7 -- Reset watchdog timer GPIO8 DO_2 Digital output 2 GPIO9 -- Status LED

Table 4. Internal connections

*GPIO4 and GPIO10 of GSM module are internally connected. Basically input on DI_4 will go to both GPIO pins GPIO4 and GPIO10. Advantage of GIO10 is that you can configure it as pulse counter for pulse rates from 0 to 1000 pulses per second. For more information about GPIO pins of GSM module TC65i and how to configure them from please refer to [1] and [2].

3.4 Watchdog

Roadstar v2 has a hardware watchdog circuit on board. Watchdog resets GSM module inside Roadstar v2 every 200 seconds as a protection in case that software in GSM module get stack. To reset watchdog timer, sotware in GSM module has to give logic “1” (positive impuls) on its GPIO7 pin for at least 200ms every 200 seconds. Best way is to give logic “1” on GPIO7 every 2 minutes (120seconds).

3.5 Operating Modes of GSM module inside Roadstar v2 The table below briefly summarizes the various operating modes referred to in the following sections. Mode Function Normal operation GSM/GPRS

SLEEP Various power save modes set with AT+CFUN command. Software is active to minimum extent. If the module was registered to the GSM network in IDLE mode, it is registered and paging with the BTS in SLEEP mode, too. Power saving can be chosen at different levels: The NON-CYCLIC SLEEP mode (AT+CFUN=0) disables the AT interface. The CYCLIC SLEEP modes AT+CFUN=7 and 9 alternatingly activate and deactivate the AT interfaces to allow permanent access to all AT commands.

GSM IDLE Software is active. Once registered to the GSM network, paging with BTS is carried out. The module is ready to send and receive.

GSM TALK Connection between two subscribers is in progress. Power consumption depends on network coverage individual set-tings, such as DTX off/on, FR/EFR/HR, hopping sequences, antenna.

GPRS IDLE Module is ready for GPRS data transfer, but no data is currently sent or received. Power consumption depends on network settings and GPRS configuration (e.g. multislot settings).

GPRS DATA

GPRS data transfer in progress. Power consumption depends on network settings (e.g. power control level), uplink / down-link data rates and GPRS configuration (e.g. used multislot settings).

POWER DOWN Normal shutdown after sending the AT^SMSO

3.6 Power Supply and GPIO pins

The power supply of the Roadstar v2 has to be a single voltage source of 8V to 30V capable of providing a peak current (pulsed 2x577ms at T=4.615ms) of about 1.2A at 12V during an active transmission.

The uplink burst causes strong ripple (drop) on the power lines. The drop voltage should not exceed 1V, but the absolute minimum voltage during drops must be >7.6V. The Roadstar v2 is protected from supply voltage reversal.

3.6.1 Turn Roadstar v2 GSM module on

Roadstar v2 GMS module switches on automaticly when power supply is attached. After start-up, the GSM module enters the net searching state.

After startup of the GSM module the RS232 lines are in an undefined state for approx. 900ms. This may cause undefined characters to be transmitted over the RS232 lines during this period.

3.6.2 Reset Roadstar v2 GSM modul

One way to reset Roadstar v2 GSM module is entering AT command AT+CFUN=x,1. For details on AT+CFUN please see [1], [2]. Other ways for restarting Roadstar v2 GSM module is:

- automatically by integrated watchdog timer on every 265seconds.

3.6.3 Turn off Roadstar v2 GSM modul Normal shutdown:

- To turn off the Roadstar v2 GSM modul use the AT^SMSO command, rather than disconnecting the power supply adapter.

This procedure lets the Roadstar v2 GSM modul log off from the network and allows the software to enter a secure state and save data before disconnecting the power supply. After AT^SMSO has been entered the GSM modul returns the following result codes: ^SMSO: MS OFF OK ^SHUTDOWN

The "^SHUTDOWN" result code indicates that the GSM module turns off in less than 1 second. After the shutdown procedure is complete the GSM module enters the POWER DOWN mode.

3.6.4 Disconnecting power supply

Before disconnecting the power supply from the Vcc pin, make sure that the Roadstar v2 is in a safe condition. The best way is to wait 1s after the "^SHUTDOWN" result code has been indicated.

3.6.5 Automatic thermal shutdown

On-board NTC measures the temperature of the built-in Roadstar v2 GSM module. If over- or under temperature is detected on the module the Roadstar v2 GSM module automatically shuts down to avoid thermal damage to the system.

The automatic shutdown procedure is equivalent to the power-down initiated with the AT^SMSO command, i.e. Roadstar v2 GSM module logs off from the network and the software enters a secure state avoiding loss of data. In IDLE mode it takes typically one minute to deregister from the network and to switch off.

Alert messages transmitted before the Roadstar v2 switches off are implemented as Unso-licited Result codes (URCs). For details see the description of AT^SCTM command provided in [1] and [2].

Thermal shutdown will be deferred if a critical temperature limit is exceeded, while an

emergency call or a call to a predefined phone number is in progress, or during a two minute guard period after power up. See [1] for details.

3.8 SIM interface

Roadstar v2 provides SIM interface with automatic detection for 1.8V and 3V SIM cards in accordance with GSM11.12 Phase 2. The card holder is a six wire interface according to GSM 11.11 with detection whether or not a SIM card is inserted.

Figure 7. SIM interface SIM card interface is placed inside the Roadstar v2 housing. Unscrew four screws marked on the left part of figure 6. and gently pull out pc board of Roadstar v2 and insert SIM card on place marked on the right part of the picture on figure 6. After placing SIM card, push back pc board of Roadstar v2 and screw four screws back. Removing and inserting the SIM card during operation requires the software to be reinitialized. Therefore, after reinserting the SIM card it is necessary to restart Roadstar v2 GSM module. Note: No guarantee can be given, nor any liability accepted, if loss of data is encountered afterremoving the SIM card during operation. Also, no guarantee can be given for properly initializing any SIM card that the user inserts after having removed a SIM card during ope-ration. In this case, the application must restart the GSM module in Roadstar v2.

3.10 Antenna interface The external antennas for GSM and GPS are connected via the Roadstar v2 SMA antenna connectors, look at figure 8.

Figure 9. Antenna interface – SMA jack

An internal antenna cable adapts the antenna reference point of GSM module (antenna connector type U.FL-R-SMT from Hirose) to the SMA connector

- Cable loss of the internal cable <0.4dB @ 900MHz <0.6dB @ 1800MHz

- The system impedance is 50Ω - In every case, for good RF performance the return loss of the customer application’s

antenna should be better than 10dB (VSWR < 2).

- Roadstar v2 GSM modul withstands a total mismatch at this connector when transmitting with power control level for maximum RF power.

Communication

HCP Roadstar track and trace terminal communicates with server via GPRS based TCP connection.

New connection

At the beginning of every new TCP connection HCP Roadstar is identifying itself to server with HCPI sentence.

HCPI sentence – Identification

Description Offset(bytes) Length(bytes) Type Sentence ID 0 1 Byte 100 TerminalID 1 8 String Terminal (vehicle) identification

IMEI 9 15 String IMEI of GSM Module DummyBytes 24 6 Byte[ ] DummyBytes for compatibility

Table 1. Identification

After receiveing HCPI sentence server must reponse to terminal with HCPO sentence.

HCPO sentence – Identification acknowledge

Description Offset(bytes) Length(bytes) Type Sentence ID 0 1 Byte 21

Table 2. Identification acknowledge

After the server has responded HCP Roadstar begins sending track data.

Track record sending

Track record(s) are sent in two ways: HCPS – One Track sentence HCPP – Sentence(s) packet Programmers Note: Easy way to identify which type is coming to server is by first byte (if first byte is greater than 30 than HCPS is coming; if less than 30 than data packet is coming.

Packet are identified as HCPP sentence.

Table 5. Track data

When server successfully receive record packet or one sentence from device, it sends acknowledgement of receiving to HCP Hunter (HCPA sentence). HCPA Sentence can contain command to be executed on terminal. This is the end of certain communication cycle which repeats for every received packet. After command is executed HCP Hunter will generate new track data record which will contain

“Command Executed Event”

Device connecting instructions: - Output Pins will give GROUND for outside relay when pins are active

- Digital Sensors are activated when positive voltage is connected

- Analog sensors are measuring positive voltage

Device programming instructions: - Output is active when state is HIGH (1)

- Input is in state LOW (0) when positive voltage is connected (reversed)

- If watch dog counter is not reseted for 240 seconds it will reset TC65i

Programming MIDlet for Roadstar Make a sync AT Command class (good practice for synchronization)

public class SyncAtCommand extends ATCommand

SyncAtCommand( boolean csdSupport ) throws ATCommandFailedException

super( csdSupport );

public synchronized String send ( String ATCmd ) throws

ATCommandFailedException

return super.send( ATCmd );

public synchronized String sendRval (String ATCmd) throws

ATCommandFailedException

String s = super.send(ATCmd);

s = s.substring(2);

s = s.substring(s.indexOf(':')+2,s.indexOf('\r'));

return s;

Have an instance of class in your “main”

SyncAtCommand ATComm2;

ATComm2 = new SyncAtCommand(false);

ATComm2.send("ATE0\r");

Configure Pins (example):

ATComm2.send("AT^SPIO=1\r");

ATComm2.send("AT^SCPIN=1,0,0\r");//for input GPIO_1



ATComm2.send("AT^SCPIN=1,4,1\r");//for output GPIO_5

ATComm2.send("AT^SCPIN=1,7,1\r");//for output GPIO_8

Join in port if needed:

INPORT = ATComm2.sendRval("at^scport=0,1,2\r");

InPortCheckCommand = "AT^SGIO=" + INPORT + '\r';

Since hardware input is reversed, if needed ,use bitmask to get “normal”

values:

PinHardwareMask = 7; (1112)

PortValue = PortValue ^ PinHardwareMask;…

5

OutputPin Function(Example)

private void SetPinVal(int PinID, int val)

try

String strRcv;

strRcv = ATComm2.send("AT^SSIO=" + PinID + "," + val + "\r");

if (strRcv.indexOf(OK) < 0) throw new ATCommandFailedException("Value

change failed");

catch(Exception ee)

Input PortReading

InPortCheckCommand = "AT^SGIO=" + INPORT + '\r';

private void CheckInPort()

try

INPORTVALUE=Integer.parseInt(ATComm2.sendRval(InPortCheckCommand));

catch(ATCommandFailedException ee)

6

ADC Reading Input is scaled to TC65i range so calculation factor is needed:

public static final double ADCFaktor = 11.44;

private static final String ADC1READCOMMAND = "AT^SRADC=0\r";

private void ObradiADC(int Koji)

try

String Response = ATComm2.send(ADC1READCOMMAND);

Response = Response.substring(Response.indexOf(":"));

Response = Response.substring(6);

Response = Response.substring(0, Response.indexOf("\r"));

ADC1 = (int)(Integer.parseInt(Response)*ADCFaktor);

catch (Exception ee)

7

PulseCount Reading: private void ActivatePulseCounter()

try

String Resp = ATComm2.send("AT^SCCNT=1,0\r");

if (Resp.indexOf("OK") >= 0)

//////System.out.println("Pulse Count OK");

else


private void ResetPulse()

try

String Resp = ATComm2.send("AT^SSCNT=0\r");

if (Resp.indexOf("OK") >= 0)

//////System.out.println("Pulse reset OK");

else


private static final String PULSECHECKCMD="AT^SSCNT=2\r";

ATComm2.send(PULSECHECKCMD);//Send pulse read command and receive answer thru

ATCommand Listener

ATList Listener = new ATList();

ATComm2.addListener(Listener);

class ATList implements ATCommandListener

public void ATEvent(String Event)

try

8

if (Event.indexOf("SSCNT") >= 0)

Event = Event.substring(Event.indexOf(":") + 2, Event.indexOf(":") + 12);

PulseCount = Integer.parseInt(Event);

catch (Exception e)

public void RINGChanged(boolean SignalState)

public void DCDChanged(boolean SignalState)

public void DSRChanged(boolean SignalState)

public void CONNChanged(boolean signalState)

GPS Reading: On beginning reset GPS:

SetPinVal(5, 1);

Thread.sleep(100);

SetPinVal(5, 0);

Open Serial port:

CommConnection commConn;

InputStream inStream;

OutputStream outStream;

String strCOM = "comm:com1;blocking=off;baudrate=9600";

commConn = (CommConnection)Connector.open(strCOM);

inStream = commConn.openInputStream();

outStream = commConn.openOutputStream();

Write uBlox start command

byte[] GPSCommandBtCommandHOT = new byte[](byte)0xB5, (byte)0x62, (byte)0x06,

(byte)0x04, (byte)0x04, (byte)0x00, (byte)0x00, (byte)0x00, (byte)0x02, (byte)0x00,

(byte)0x10, (byte)0x68;

outStream.write(GPSCommandBtCommandHOT, 0, GPSCommandBtCommandHOT.length);

Read NMEA data:

byte nmea[] = new byte[1000];

int read = inStream.read(nmea);

… Parse data…

10

Reset WatchDog: public void RestartWatchDog()

try

for(int i =0;i<2; i++)

SetPinVal (6,1);

Thread.sleep(1);

SetPinVal(6,0);

Thread.sleep(1);

GPRS Sending: SocketConnection commConn;

InputStream inStream;

OutputStream outStream;

String connProfile = "bearer_type=gprs;access_point="

+ APNString + ";username="

+ GPRSUserString + ";password="

+ GPRSPasswordString + ";timeout=60";

String serv = "socket://" + ServerIPString + ":"

+ ServerPortString + ";" + connProfile;

commConn = (SocketConnection) Connector.open(serv,

Connector.READ_WRITE, true);

outStream = commConn.openOutputStream();

inStream = commConn.openInputStream();

Send and Receive data using streams…

Important tips:

TC65i Restart: public void restartMod()

try

String strRcv;

strRcv = ATComm1.send("AT+CFUN=1,1\r");

if (strRcv.indexOf("OK") < 0)

throw new ATCommandFailedException("Couldn't restart");

else

Thread.sleep(10000);

catch (Exception e)

Network Params: If have problems connecting make a routine to check network params

CREG

If CREG==0 you should probably restart TC65i using

AT+CFUN=1,1\r command

ATComandListener: In time to time check is you ATCommandListener working properly by sending

PulseRead command and verify receiving answer. It is a rare problem and in most

cases caused by implementation of lot of code inside listener. If listener stop

working, restart TC65i.

GarbageColector: From time to time activate garbage collector to free up memory:

Runtime.getRuntime().gc();
