Page 10: Chapter 2 Board Settings
User’s Manual OARD SETTINGS Chapter 2 The GSM35 board has jumper settings, which can be changed to suit your application and host computer configuration. The factory settings are listed and shown in the diagram at the beginning of this chapter. Make sure you completely study and understand this chapter before making changes to these settings. -
Page 11: Factory Configured Jumper Settings
Factory-Configured Jumper Settings Table 2-1 below illustrates the factory jumper setting for the GSM35. Figure 2-1 shows the board layout of the GSM35 and the locations of the jumpers. The following paragraphs explain how to change the factory jumper settings to suit your specific application. -
Page 12: Base Address Jumpers
User’s Manual Base address jumpers (Factory setting: 2E8h / 6E8h) The GSM35 is I/O mapped into the memory space of your host XT/AT. The board occupies a consecutive memory window of 8 bytes starting from the base address for UART communication and 4 consecutive bytes starting from BASE+400h for the board control and status registers. - Page 13 BASE A8 A7 A6 A5 A4 A3 BASE A8 A7 A6 A5 A4 A3 0 = JUMPER OFF 1 = JUMPER CLOSED Table 2-2 Base address jumper settings for the GSM35, the default jumper setting is highlighted.

Page 20: The Gsm Wireless Modem Module
User’s Manual The GSM wireless modem module The GSM35 wireless GSM modem is built around the Siemens TC35 dual band 900/1800MHz cellular engine. It is designed both for handling complex industrial applications such as telemetry, telematics or communication, and for integration in stationary or mobile fields all over the world. -

User’s Manual OARD OPERATION AND PROGRAMMING Chapter 5 This chapter shows you how to program and use your GSM35. It provides a general description of the I/O map. Detailed serial port programming tips are not within the scope of this manual. -
Page 24: Gsm Base+400H Digital I/O
This address is used to interface to the digital I/O port of the GSM35, writing to this address will transfer the data out of the output port, while reading from this address will return the data from the digital inputs. -
Page 25: Starting Up And Logging Into The Gsm Network
After this the status LED will blink for a while until the TC35 is logged into the network. If you have the PIN code enabled, the GSM35 status LED will continue to blink until the PIN code is given through the terminal mode with AT command AT+CPIN”XXXX”, unless AT^SFLC (facility lock for PIN code) has been set. - Page 26 Understanding the sequence of events when an interrupt is triggered is necessary to correctly write interrupt handlers. When an interrupt request line is driven high by a peripheral device (such as the GSM35), the interrupt controller checks to see if interrupts are enabled for that IRQ. It then checks to see if other interrupts are active or requested and determines which interrupt has priority.
- Page 27 Second, just before exiting the routine, you must clear the interrupt on the GSM35 by writing to the Status register, and write the EOI command to the interrupt controller. Finally, when exiting the interrupt routine the processor registers must be popped from the system stack and you must execute the IRET assembly instruction.
- Page 28 Push any processor registers used in your ISR. Put the body of your routine here Clear the interrupt bit by reading GSM35 RXD register Issue the EOI command to the 8259 by writing 20h to 20h Pop all registers. Most C compilers do this automatically...
- Page 29 The vectors for the hardware interrupts on the XT - bus are vectors 8-15, where IRQ0 uses vector 8 and IRQ7 uses vector 15. Thus if your GSM35 is using IRQ5 it corresponds to vector number 13.
