1 Overview
This Document is intended to provide the user complete instructions on the capabilities and use of the Wavecom Starter Kit. The Wavecom Starter Kit is designed to allow the customer to interface to the Wavecom Q2300 and Q2400 CDMA and GSM/GPRS Module families. Control of the Module is done via AT Commands issued from an external PC running a terminal emulator, such as HyperTerminal. The User should refer to the Wavecom
Commands Interface Specification
for more information on supported
commands.

2 Product Description
The Wavecom Starter Kit includes the following:
Interface Board
The Interface Board provides a working platform for testing and evaluating the performance of the Module, as well as allowing customer design of host software interfaces.
Module
One Wavecom module is included with the Starter Kit and comes pre­assembled on the Interface Board. The Module is soldered down via its four Ground contact pins, and is also mated to the 60 pin board-to-board connector of the Interface Board.
Handset
The Handset contains a standard telephony earpiece and microphone, providing a full audio interface to the Module through the Interface Board connectors.
Serial Cable
The Serial Cable connects the Interface Board to the controlling PC.
Antenna and RF Adapter
The Antenna provides sufficient omni-directional gain to allow the module to go over the air on the network. An Antenna Adapter is provided to allow the Antenna Cable to connect to the RF Connector of the Module.
Power Adapter
The included Power Adapter allows for use of the Starter Kit without the need for a lab power supply. The Adapter can source enough current to support CDMA, GSM, and GPRS modules at full transmit power, as well as the operation of the Interface Board. Some Kits may include a lab power supply cable instead of, or in addition to, the Power Adapter.

3 Description of the Interfaces
3.1 Power
A standard DC Power Jack is provided on the Interface Board. The included Power Adapter can be used to supply the Module and Interface Board via this jack.
Alternatively a lab power supply capable of supplying at least 3.8Vdc at
2.0Amps can be used. The advantage of the lab power supply is in allowing the user to monitor the current drain of the Module to help determine its operating state.
The Power Jack has a center positive connection, if a lab supply or other external source is used. A cable for this purpose is available.
3.2 Computer
The Interface Board communicates with the controlling PC through standard RS-232 Interfaces. Two such interfaces are provided, however the typical customer application will only require one of these (DATA).
3.2.1 DATA
The DATA Interface, J200, provides a full 8 wire RS-232 interface with the PC. This interface supports the AT Commands; the Diagnostic (DM) information; and high speed data.
Light Emitting Diodes (LEDs) for this port are included on the Interface Board on the RX, TX, DTR, DSR, RTS, CTS and DCD lines to indicate the state of the line. The red LED indicates a negative voltage on the RS-232 (Logic 1) and the green LED indicates a positive voltage on the RS-232 (Logic 0).
3.2.2 DM
The DM Interface, J201, provides a 2 wire RS-232 interface for Diagnostic information only. The typical customer application should not require this interface as all functionality of the DM Interface is now supported through the DATA Interface as well.
Light Emitting Diodes (LEDs) for this port are included on the Interface Board on both the RX and TX lines to indicate the state of the line. The red LED indicates a negative voltage on the RS-232 (Logic 1) and the green LED indicates a positive voltage on the RS-232 (Logic 0).

3.3 Switches and Jumpers
3.3.1 ON/OFF Switch
There is a slide switch, SW101, located on the back edge of the Interface Board. This switch interfaces directly to the ON/OFF control line of the Module, via pin 6 of the board-to-board connector. Sliding the switch in the “OFF” direction will pull the line low, causing the Module to shut off. Sliding the switch in the “ON” direction will pull the line high, turning on the Module and keeping it in the ON state.
3.3.2 BOOT Switch
A second slide switch, SW102, is located on the back edge of the Interface Board, beside the ON/OFF switch. The function of this switch depends on if a CDMA Module or GSM/GPRS Module is being used.
For normal operation of the GSM Module, this switch must be in the HI position upon power up or reset. This switch when in the LO position will put the GSM Module into its BOOT Mode. This allows software upgrades to the embedded code within the Module, via the serial interface of the Interface Board and an application such as the Wavecom DWLWin program. Note that the switch must be in the LO state upon power up or reset. Once the embedded code is executing, the status of the BOOT input is no longer monitored.
For the CDMA Modules, there is no need for this BOOT functionality. Thus this switch is for test purposes only and is connected to GPIO 42 of the Module. The input can be pulled LO or HI and monitored via AT Command Queries if needed.
3.3.3 RESET Switch
There is a master push button reset switch, SW100, located in the middle of the Interface Board that when depressed will pull the RESET/ line of the Module to Ground, causing a full Module microprocessor reset.
3.3.4 SNGL/DIFF Jumper
A four-pin jumper, J303, is located near the Audio connectors. This is used to configure the Headset Audio for either a single ended or differential speaker drive circuit. Silkscreen on the Interface Board indicates the jumper positions required for either case. For Differential, one jumper should be placed across pins 2 and 3. For Single Ended, two jumpers should be placed; one across pins 1 and 2, and the other across pins 3 and 4. Refer to
Audio
for more
details on the functionality of this jumper block.
