The Enfora SDK (Software Developer’s Kit) is designed to allow Enfora partners to
evaluate the Enfora Enabler III module and develop their own applications that will use
the Enfora Enabler module.

you must remove R200 located next to SW201 (RESET) else the module will be
held in permanent reset. There is no reset supported with this combination of
hardware.

RF connector
There are two RF cable assemblies. An SMA Connector has been provided to facilitate
using an external antenna (or port to test equipment) as well as an RF cable assembly
connecting an internal quad band antenna.
External SIM Connector
An external SIM connector is provided on the SDK. Users may use either the external
SIM or a SIM connector on the module (if configured), but not both at the same time.
The SIM CLOCK, control and data lines are physically the same lines that go to the on
board SIM. SIM’s cannot be installed both on the external SIM connector and the on
board SIM connector. It must be one or the other.
Audio Section
The audio section has a 4-pole stereo headset connector (J700) and separate speaker and
microphone handset connectors (J702 and J703). The audio path is configured with
AT$VSELECT command. AT$VSELECT=0 selects handset and AT$VSELECT=1
selects headset. Please see the AT command manual for the audio level commands.
GPIO Section
DIP switches and LED’s have been provided to help facilitate testing of GPIO and GPIO
based events. Each GPIO is tied to a DIP switch (SW401) and pulled up high through a
resistor. If the GPIO is configured as an input (See AT$IOCFG), a high or low can be
applied to each GPIO line by setting the corresponding DIP switch to open or closed. If
it is open, the line will be pulled high. If it is closed the line will be pulled low.
Each GPIO line also has a corresponding LED. These LED’s show the current state of
the GPIO. The opposite side of the LED is tied to ground. If the LED is illuminated,
then the GPIO line is high. If it is not illuminated, then the GPIO line is low
Serial Ports
The SDK has a standard serial port and USB serial debug port. The RS232 modem port
(J601) is the modem primary serial port. Prior to RS 232 conversion, each hardware line
is tied to a status LED. On the opposite side of the LED, each is tied to ground. If the
LED is illuminated the line is high, if it is not illuminated, the line is low.
The debug USB serial port (J600) is used for modem debugging and is for Enfora use
only. There is no control of the modem through the debug serial port.
Power Input Port
J202 is the power input port. The connector is of size 1.3mm inner and 3.8mm outer.
Centre pin is positive. Power supply input range is 4.5V – 9V maximum.
Debug headers
J400, J401, J403 and J404, located in the center of the board, bring each line from the
100-pin connector to a header pin, for ease of monitoring and troubleshooting.
Page 5
To use some features on the SDK, jumpers must be placed on the debug headers to link in
the feature. Removal of the jumper will isolate the SDK feature from the module to
allow for external circuitry to be added via the headers without interference from the
SDK.
The Factory Default for the Debug header jumper settings are: (all other pins are not
jumpered)
J401:
LED_A > LEDA_J
VRWLED > VRWLEDJ
J403:
USB_VBUS > USB_VBUS_J
DTR > DTR_J

Configuring the Enfora module
To communicate with, and configure the Enfora module, connect the serial connector of
the SDK to the serial port of a PC. From a Windows PC, you can use HyperTerminal to
configure the module. Please follow these instructions to correctly configure
HyperTerminal:
a. Start HyperTerminal
On Windows XP, click on:
Start>Programs>Accessories>Communications>HyperTerminal
1. You should see the following screen.
2. Enter a name for the Connection. In this example, the Name is
Enfora Com1.
3. Click OK.
4. The next window that will appear is the Connect To window.
Page 7
5. Change the Connect Using setting to the Com port that was
determined in Step 2.
6. Click OK.
7. The next window is the Port Settings window.
Page 8
8. Make sure the settings match the example.
9. Click OK.
10. Now the Main Program Window should appear.
11. Terminal Setup Testing.
a. Make sure the cursor is in the main window.
b. Type “AT” and press “Enter”
c. You should see the modem respond back with “OK” in the
Main Window
d. If this happens, the COM port is configured correctly.
e. At this point you are ready to start configuring your SDK with
AT commands.
Page 9
Modem Settings that Allow for Automated GSM and GPRS Network Connectivity
1. Open the HyperTerminal connection that you configured in the previous section.
2. Type AT and press <ENTER> the modem should respond with OK. This will
verify that you are communicating with the modem. If you cannot see characters
entered on the screen, enter ATE1V1.
3. To perform a PDP context activation on a network, the following commands need
to be used:
AT&F (Default configuration)
AT+CREG=2 (status GSM registration)
AT%CGREG=2 (Status GPRS attach)
AT+CGDCONT=1,"IP","APN","",0,0 (.APN value will be provided by carrier. )
AT%CGPCO=1,"username,password",1 (Set Type of Authentication, Username and
Password if is need it)
AT+CPIN="xxxx" (xxx is a PIN number for SIM card if
needed)
AT$AREG=2 (auto GPRS activation on power up of
device)
AT&W (save the configuration)
SDK Tips
Before using the SDK for the first time, please make sure you remove all packing
material from the SDK (tape, etc.).
Enfora Parts
The SDK includes: The SDK Board and AC/DC “Wall-Pack” Power Supply. (Note:
The AC/DC Adapter is only supplied in the United States.)
There are optional accessories that you may need in addition to the Enfora module. Some
examples of these accessories are listed below. Please contact your Enfora sales
representative for specific part information, and ordering information.
• Molex Connector
• SIM Card Holder
