• An adapter for external connector to serial
  interfaces signals
• USB cable (for charging only)

Features

• The XT55 DT supports all known features of the
  XT55 module.
• XT55 DT has a 1300mAh battery on board for
  mobility and power interruption. The working time
  (continuous tracking) of the battery is about
  7...8h.

Antenna

• The GPS and GSM antenna must be connected at the
  two antenna connectors (FME and SMA). It is
  recommended to use the supplied antenna, which is
  a GSM/GPS combo antenna.
• The active GPS antenna part is configured for 3V
  the XT55 DT is configured for 3V antennas as
  well (while the XT55 module supports all antennas
  within a range of38V). The SMA is for connecting
  the GPS part and the FME for connecting the GSM
  part of the antenna.

30 pin connector

• Serial interface 14 (ASC0 1 of the GSM, SD1
  2 of the
• GPS part)
• Power input (external supply for charging 5Vmin,
  600mA
• limited)
• Regulated power output (5V, 200mA limited) for
  external
• applications
• Several GPIOs with different functions
  according to the used
• SW packages

7
Lumberg connector

• Audio output interface 1 (EP1_1)
• Audio input interface 2 (MIC_2)
• Power (Battery charging via a Siemens mobile
  charger)

8
Push buttons

• XT55 DT has 4 push buttons to control or set the
  status of the device
• These are two different Alerts, Power down and
  Ignition / Switch off

9
Switches

• SiRF Drive switch (1) decides between using SiRF
  Drive or AVL SW package. Set it to ON to use
  AVL or set it to OFF to use SiRF Drive
• AVL, TCP/IP switch (2) is used to connect or
  disconnect the serial interface SD2 to ASC0 of
  the GSM part. ON SD2 connected to ASC0
• Xtrac switch (3) only if you use SiRF Xtrac set
  to on
• Bootselect switch (4) if the GPS software should
  be updated set this switch to ON. Then switch
  the module off and restart

10
LEDs

• 1 VDD signal this LED lights, if the XT55 is
  switched on.
• 2 SYNC signal is synchronized with the GSM
  transmit burst. The LED is flickering when a GSM
  transmit is ongoing.
• 3 RING signal shows the state of the ring line.
  An incoming call activates this signal.
• Trickle-Power clock signal
• LED 4 shows a clock signal between GPO4 and
  GPS_RFPC1. It indicates a control signal for
  Trickle-Power mode. This LED is flashing, if the
  GPS part is running in Trickle Power mode.
• LED 5 shows a clock signal between GPO8 and
  PS_RFPC0. It indicates a control signalfor
  Trickle Power mode. This LED is flashing, if the
  GPS part is running in Trickle Power mode.
