3 Interface Functions of the DVK
3.1 About This Chapter
This chapter describes interface functions, and interface usage of the DVK.
Interface Functions
3.2 Interface Functions
3.2.1 Power Switch and Power Supply Mode
Power can be supplied to the DVK in two modes: by a 5V AC-DC power adapter or
the USB 5V power supply.
The jumper wire POWER-SWITCH is used to select a power supply mode. When
pin1 and pin2 are connected, the USB 5V power supply is used; when pin2 and pin3
are connected, the 5V AC-DC power adapter is used. Only one mode can be
selected at a same time. Once the development kit is powered on, the power
indicator lights up.
Figure 3-1 Power is supplied by the 5V AC-DC power adapter

3.2.2 USB Communication Interface
The DVK provides a mini USB B-type connector. The connector implements
communications between the module and a personal computer (PC) or other data
terminal equipment (DTE) and supports USB analyzers.
3.2.3 LED Indicators
The DVK has five LED indicators: one power indicator and four signal indicators.
Figure 3-3 Power indicator
The descriptions of all four signal indicators are marked on the development kit.
Notes: The function of signal indicators of ME909 module is under development.

Figure 3-4 Signal indicators
3.2.4 Buttons
The DVK has two buttons: the power button and the reset button, please refer to the
Figure 1-1 .
The power button(marked as "TERM_ON") powers on or off the module. The
power-on/power-off signal of the module is at low level when the button is pressed.
The reset button(marked as "RESET") resets the module. The reset signal of the
module is at low level when the button is pressed.
Notes: The function of power-off and reset of ME909 module is under development.
3.2.5 USIM Card Interface
The DVK provides a standard USIM card slot (marked as "SIM CARD").
3.2.6 Antenna Connector
The DVK provides three antenna connectors for connecting the MAIN, AUX and GPS
antenna of the module.
The antenna connector can be connected to an RF tester (CMU200 or Agilent 8960),
or directly connected to an external antenna for testing the services of the existing
network.
