PIC-GSM development board Users Manual
All boards produced by Olimex are ROHS compliant
Rev.A, June 2008Copyright(c) 2008, OLIMEX Ltd, All rights reserved
INTRODUCTION:PIC-GSM is excellent board for adding remote monitoring and control inremote places by GSM cellular network or ethernet or internet network. Doyou want to switch on/off your local heating in your mountain house? Tomonitor the temperature at up to 8 remote points up to 30 meters awayfrom the module? To listen what happens in your house with silent callafter you get message for alarm status? Then PIC-GSM is the board foryou! It contains PIC18F97J60 microcontroller and 3-band GSM GPRSmodule 900/1800/1900Mhz inside which covers most used GSM networksaround the world. The GSM antenna is build in the board so no need forexternal expensive GSM antennas. PIC-GSM have two relays 240VAC/10A,two opto-isolated inputs which could be connected to alarm sensors or justbuttons for user actions (like call pre-loaded phone numbers), on-boardtemperature sensor and connector for additional up to 8 addressableremote temperature sensors at up to 30 meter distance from the module.Normal phone hook can be connected to this board and to allow user tospeak, listen, taking and placing phone calls as normal stand alonecellular phone. PIC-GSM can be connected to PC with the USB connector ithave and it is recognized as modem which could be used to add internetvia GPRS to your computer (imagine how useful is this for your mountainhouse if there is no internet but only cellular network!). If you haveinternet connection you can monitor the same parameters on the WEBpage.
BOARD FEATURES:
• ICSP/ICD connector for programming and debugging with PIC-ICD2, PIC-ICD2-POCKET, PIC-ICD2-TINY;USB 2.0 type B connector allow board to be interfaced to PC host;
• GSM/GPRS module 900/1800/1900Mhz;• Li-ion backup battery;• PIC18F97J60-I/PT;• Ethernet RJ45 isolated connector.• GSM Audio In and Out;• RS232 connector;• Quartz crystal 20Mhz;• Two relays 10A/250VAC;• Two digital inputs;• Analog input;• Temperature sensor;• 5V voltage regulator;• EXT connector for available GPIO;• Four mounting holes 3,3 mm (0,13");• FR-4, 1.5 mm (0,062"), green soldermask, white silkscreen
component print;• Dimensions 124x90 mm (4880 x 3540 mils);
ELECTROSTATIC WARNING:
The PIC-GSM board is shipped in protective anti-static packaging. Theboard must not be subject to high electrostatic potentials. General practicefor working with static sensitive devices should be applied when workingwith this board.
BOARD USE REQUIREMENTS:
Cables: 1.8 meter USB A-B cable to connect to USB host on PC.Crossed ethernet cable if the PIC-GSM module is connected toPC or straight if the module is connected to router or ethernetswitch.
Hardware: PIC-ICD2, PIC-ICD2-POCKET, PIC-ICD2-TINYOr any compatible tool for programming and/or debugging
!!!Warning!!! When you want to program this microcontrollerwith PIC-ICD2, PIC-ICD2-POCKET or PIC-ICD2-TINY, beforeconnecting the programmer to your target board, you shouldfirst connect the programmer to your computer and openMPLAB. There, first from menu Configure – Select Device –choose the microcontroller you are about to program, thenfrom menu Programmer – Select Programmer – choose MPLABICD 2, wait while MPLAB is downloading operation system,and after ICD2 is connected – check in menu Programmer –Settings – Power – there is option – Power target circuit fromMPLAB ICD 2 – this option should be forbidden, you could notselect it. Now it is safe to connect the programmer to yourtarget board.
Software: Microchip MPLAB IDE + C18 C compiler for developing yourown applicationsThe demo software show basic functionality and how to place /take phone calls (C source and HEX) or how to remote controlvia SMS and WEB page(C source and HEX)
Important: If your board does not work, first try to charge the battery asyou power supply the board for few hours.

BOARD LAYOUT:
POWER SUPPLY CIRCUIT:The power supply of PIC-GSM could be done in two different ways:
1. Power from +12VDC without using the internal backup battery.The module is powered only from external 12V and the battery is notconnected. In this case:− jumper BAT_E must be open− jumper 4V_E must be closed− jumper 4V_VBAT must be closed − jumper 5V_CHG_E must be open.
Power consumption in this mode is:− about 240mA when have a conversation.− About 90mA in normal mode (without conversation) and active
WEB interface + 60mA if relays are turned on.
Important: 4V_E, 4V and 5V_CHG_E jumpers have to be movedtogether.
2. Power from +12VDC with backup battery.The module is powered with battery and allows battery charging. Inthis case:− jumper BAT_E must be closed− jumper 4V_E must be open
− jumper 4V_VBAT must be open − jumper 5V_CHG_E must be closed − Power consumption in this mode: depend on the battery charge
may vary between 90mA and 300mA. − If the 12V power supply is missing the battery discharge current
depend from activated microcontroler modules. Max currentconsumption reach up to 500 mA when all microcontroler modulsare switched on and have a conversation.
RESET CIRCUIT:
PIC-GSM reset circuit is made with RC group and optional STM1001R chipwith typical threshold +2.63V. By default STM1001R chip is not assembled
CLOCK CIRCUIT:

JUMPER DESCRIPTION:
BAT_E Connects 3.7V Li-ion battery to the GSM module. Default stateis to be open to not drain the battery during stocking themodules.
Default state - open
4V_E When this jumper is open state the DCDC voltage output is setto 5V, when the jumper is closed the DCDC output voltage isset to 4V. This is necessary when the main battery is notconnected and the supply voltage should be 4V, when thebattery is connected 4V_E jumper must be open and the DCDCvoltage should be 5V.
Default state – open.
4V_VBAT When the main battery is not present, this jumper feeds the 4Vfrom the DCDC output to the GSM module.
Default state – open.
5V_CHG_E The GSM module have build in li-ion charge circuit. Thisjumper connects the DCDC 5V output to the internal chargercircuit.
Default state closed
Important: 4V_E, 4V and 5V_CHG_E jumpers have to bemoved together.
Do not plug in external +12V if BAT_E jumper is open!
You should be very careful for battery voltage, whichshould be over 3.8 V, never lower. Battery is charged whenvoltage is 4.1 V.
DCDC_E This jumper connects the DCDC output to the GSM module. Itis useful to measure the current consumption.
Default state closed
3V_E This jumper connects +3V to FT232RL and PIC18F97J60.It isuseful to measure the current consumption.
Default state closed
Download This is GSM module bootloader enable pin. Reserved for GSMmodule firmware upgrade.
Default state – open.
MTX/DTX The GSM module have two UART channels. One for thecommands, one for debugging. With this jumper you controlwhich channel goes to PIC18F97J60 or FT232RL.
MTX/DTX
Default state MTX
MRX/DRX The GSM module have two UART channels. One for thecommands, one for debugging. With this jumper you controlwhich channel goes to PIC18F97J60 or FT232RL.
MRX/DRX
Default state MRX
J1,J2 These jumpers allow to switch the virtual RS232communication port of the FT232RL chip to the MTX/DTXcontroller or to the SIM300D module. Default configuration isSIM300D module to communicates with FT232RL chip, but ifyou wish to use USART communication option of MicrochipTCP/IP stack, you can switch J1 and J2 jumpers. When J1and J2 jumpers are to 1-2 state - serial communication fromFT232RL chip is connected to the GSM module. You can usevirtual com port for communication with GSM module. ThePIC18F97J60 microcontroller however must release RXD andTXD pins. When J1 and J2 jumpers are to 2-3 state - serialcommunication from FT232RL chip is connected to thePIC18F97J60 microcontroller. You can use virtual com port forcommunication with PIC18F97J60. MTX/DTX and MRX/DRXjumpers however must be open and you can not communicatewith GSM module.

AVAILABLE DEMO SOFTWARE:
2. Software notes
Software, that PIC-GSM board is shipped with, includes Microchip TCP/IP stack iscombined with simple functionality for making calls and sending SMS with SIM300DGSM/GPRS module. This note explains features of PIC-GSM board. For more informationon the Microchip TCP/IP Stack, please refer to application note AN833 available athttp://www.microchip.com.
SMS sending functionality is strongly dependent of serial communication betweenPIC18F67J60 MCU and SIM300D module. Consequently board software functions are verysensitive to any messages send from SIM300D module. For example, when SIM300Dmodule goes to specific states(POWER DOWN, Call Ready etc), it sends indicating messagesvia serial line, which can affect communication with PIC18F97J60 and cause wrongbehavior of software.
Specific features:• First time you insert power to board USB should not be connected to board due to
initialization procedures between PIC and GSM module.• UART baud rate, which ensures best performance is 115200 bps. Other specific
features, which software rely on are:• Disable echo(command used is ATE0)• Set SMS text format (command used is AT+CMGF=1)
• After board power-up software continuously sends “AT” command expecting “OK”string, ensuring proper communication with GSM module.
• Software allows to dial GSM and make GSM call, getting GSM number or SMS textfrom web page form. GSM number length is 16 digits
• Software allows sending SMS getting GSM number and SMS text from web pageforms. GSM number must be typed with country code without “+” sign. GSM numberlength is 16 digits and SMS message length 32 digits.
• Status page item “Open Call” displays information about call processing .”0”indicates that no call is in process. “1” indicates that GSM call is in process. (AfterGSM number is dialed, “Open Call” value is set to “1”, if other side close call after awhile “Open Call” value returns back to “0”. If other side accept call, “Open Call”value remains “1”, for the time of call is in process. When call is closed “Open Call”value is set back to “0”)
• PIC-GSM Board has 2 audio channels – one connected to MIC, and auxiliaryconnected to HANDSFREE. You can switch to next audio channel by pressingbutton B1.
• Pressing button toggle the on board buzzer unless the GSM module is not in opencall mode.
• When you plug USB cable to the board, the FTDI chip on the board emulates virtualCOM port and you can connect to SIM300D module with HyperTerminal. Firsthowever have to install FTDI drivers available on the http://www.ftdichip.com/
• Temperature, displayed on web page is read from SIM300D module with ATcommand (AT+CMTE?). Any problem with correct displaying temperature, is relatedwith correct handling of used AT command output or GSM module response. Thismeasurement should not be treated as reliable .
• Another useful feature is ability of getting temperatures from up to 8 externaltemperature sensors TCN75A connected via I2C interface. In "Temperature sensorspresence" each item stands for presence of sensor with given hardware address 000for Temp sensor 1, 001 for temp sensor 2, ... and 111 for temp sensor 8."Temperature measured by sensors" section contains temperature in C° measured bysensor(s) available.
• Items: Relay 1, Relay 2 and LED buttons from “Status” section display voltageapplied to corresponding input/output 1- high voltage; 0 – low voltage.
Log “1” of Relay1 (PG7) and Relay2 (PG6) outputs means that the Relay is turned on,while log “0” mean that the Relay is turned off. Log “1” to the LED output (PG5) means that LED is turned off, while log “0” meanthat the LED is turned on. Logical “1” on Opto input 1(RG3) and Opto input 2 (RG4) means that high voltage isapplied to the input
• Status page item “seconds” displays seconds elapsed from program start, measuredby RTC.
• Status page item “Uin” displays input voltage in Volts, measured on RA5(AN4) pin . • “Test board area” section is not intended for user examination and shouldn't be used
by customer.Advices to customer for further use:
• User should be familiar with basic AT commands(make call, send SMS, read SMSetc).
• SIM card, you put should be with disabled PIN code use. So before use, put SIM cardin normal GSM and disable PIN code use.
