Firmware update: Upgradeable via serial interface / USB Java Midlet: Major benefits: integration into Java applications, no need for application microcontroller, extremely cost-efficient hardware and software design – ideal platform for industrial GSM applications. The memory space available for Java programs is 10.0 MB flash file system and 1.8 MB RAM. Application code and data share the space in the flash file system and in RAM. Interface Serial interface:
• 8-wire modem interface with status and control lines, unbalanced, asynchronous
• Fixed bit rates: 300 bps to 460,800 bps
• Autobauding: 300 bps to 57,600 bps
• Multiplex ability according to GSM 07.10 Multiplexer Protocol. I²C: The I²C interface bus for transmission rates up to 100kbps. Audio: Analog (Microphone amplifier ready, Speaker with 3W amplifier option) 2.5mm output audio SIM interface: Supported SIM cards: 3V Antenna: Connected via antenna SMA connector or internal antenna Power on/off, Reset Power-on:
1. Automatic on when power supply turn on ( IGN switch set on )
2. Switch on via On/Off push button
3. On/Off line on IO interface connector Power-off: Normal switch-off by AT or On/Off push button Reset: Shutdown and reset by AT command Special features
GPIO: 16 I/O pins of the application interface are programmable as GPIO.
Programming is done via AT commands. Alternatively, ADC: input Analog-to-Digital Converter input for measuring external voltages.
Optional measuring supply voltage to the unit.
Phonebook: SIM and phone |
