  • Page 32: Sim Card Reader

    GM28 INTEGRATOR’S MANUAL 2.4 SIM Card Reader The GM28 is fitted with a SIM card reader designed for 3V and 5V SIM cards. It is the flip-up type which is lockable in the horizontal position and is accessed through a removable panel as shown below.

  • Page 33: Rs232 Serial Port

    The modem supports a standard RS232 serial interface (EIA/TIA 574) via its 9 pin Sub-D connector, shown below. In line with serial communication terminology the GM28 serial modem should be considered as the data circuit-terminating equipment (DCE) and the external application or computer as the data terminating equipment (DTE).

  • Page 34: Serial Data

    2.5.2 Serial Data Signals - RD, TD The default baud rate is 9.6kbps, however higher bit rates up to 460kbps are supported. At start-up the GM28 transmits and receives data at the default rate of 9.6kbps in either standard AT mode or binary mode (the first received data - AT or binary format - determines the operating mode).

  • Page 35: Real Time Clock

    The RTC is powered when d.c. power is connected to the modem AND the modem is switched on. If the d.c. supply fails, a stored energy device within the GM28 provides back-up power to maintain the RTC for at least 12 hours.

  • Page 36: Operation

    GM28 INTEGRATOR’S MANUAL 3. Operation 3.1 Switching On the Modem There are two ways to switch on the modem, once power is applied. • either assert TO_IN high for > 0.2s; • or activate the RS232 control line DTR, high for > 0.2s.

  • Page 37: Operating States/Led

    Switch off (Power Down): DC power is applied but the modem is switched OFF. Standby: The GM28 is switched ON and camped on to the network. No call in progress. Talk: The GM28 is switched ON and a voice/data call is in progress.

  • Page 38: Safety And Product Care

    4.2 General Precautions • The GM28 as a stand alone item is designed for indoor use only. To use outside it must be integrated into a weatherproof enclosure. Do not exceed the environmental and electrical limits as specified in “Technical Data”, page 46.

  • Page 39: Sim Card Precautions

    4. SAFETY AND PRODUCT CARE • Ensure the d.c. cable, supplying power to the GM28, does not exceed 3 metres. For longer distances please contact Sony Ericsson (see “Service and Support”, page 20). • To protect power supply cables and meet the fire safety requirements when the unit is powered from a battery or a high current supply, connect a fast 1.25A fuse in line with the positive supply.
  • Page 40 GM28 INTEGRATOR’S MANUAL • If the application containing the GM28 uses an antenna which is less than 20cm away from any part of the user’s body, integrators are legally obliged to publish SAR figures for the product. SAR testing is the responsibility of the system integrator.
