Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant
delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used
in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used
in situations where failure to transmit or receive data could result in damage of any kind to the user or
any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless
accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or
received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or
receive such data.
Safety and Hazards
Do not operate the Sierra Wireless modem in areas where blasting is in progress, where explosive
atmospheres may be present, near medical equipment, near life support equipment, or any equipment
which may be susceptible to any form of radio interference. In such areas, the Sierra Wireless modem
MUST BE POWERED OFF. The Sierra Wireless modem can transmit signals that could interfere with
this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is on
the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When
operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard
systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is
open. Sierra Wireless modems may be used at this time.
The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of
a vehicle. Doing so will detract from the driver or operator’s control and operation of that vehicle. In
some states and provinces, operating such communications devices while in control of a vehicle is an
offence.
Limitations of Liability
This manual is provided “as is”. Sierra Wireless makes no warranties of any kind, either expressed or
implied, including any implied warranties of merchantability, fitness for a particular purpose, or
noninfringement. The recipient of the manual shall endorse all risks arising from its use.
The information in this manual is subject to change without notice and does not represent a
commitment on the part of Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES
SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL DIRECT, INDIRECT, SPECIAL,
GENERAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES INCLUDING,
BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR
REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS
PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR CLAIMS BY ANY
THIRD PARTY.
Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its affiliates aggregate liability
arising under or in connection with the Sierra Wireless product, regardless of the number of events,
occurrences, or claims giving rise to liability, be in excess of the price paid by the purchaser for the
Sierra Wireless product.

2.2. Bottom View
J800 and J801 connectors provide the same signals.
It is possible to access the module memory on either of these two connectors.
J801 provides a voltage reference (for pull-up). This is the “VCC_2V8” signal, a 2.8v voltage.

3. General Description
3.1. WMP Development Kit
All WMP Development Kit functionality is provided by the module. Interfaces on the board include:
1 external board to board connector and test point (TP) to access all signals for the module
(except memory signals)
Memory interface
Main serial link RS232, UART1(*) with full signals
Ring Indicator
Auxiliary serial link RS232, UART2(*) with 4 signals
Slave USB(*), with SoftConnect™ signal. Compliant USB 2.0 (full speed)
SIM* 1.8/3v with management of SIM presence
6-button Keypad
2 AUDIO(*) connectors (AUDIO 1, AUDIO 2)
LEDs for several indications
RESET Pushbutton
Power supply connectors
ON/OFF switch
BOOT switch
Buzzer LED
Flash LED
Charger Interface with a charging LED
(*) One feature of the WMP Development Kit is that each signal’s peripheral can be independently
removed, electrically, via special soldering. (Refer to § 3.2 for more information).
Note: The WMP Development Kit complies with the Q26 Development Kit regarding the pin out of the
External Board connector (J1100).
3.2. Special Soldering
PCB prints are used for the peripherals that are electrically removable.
To connect signals between the module (from J1000 and J1001) and the dedicated connectors on the
Development Kit, solder these PCB prints.
To connect signals between the module and the external board connector (J1100) is recommended
not to solder the PCB prints (i.e. prototyped a daughter board).
The interfaces (or signals) listed below are electrically removable via special soldering:
UART1 (from J101 to J108)
UART2 (from J201 to J204)
AUDIO1 (from J706 to J709)
AUDIO2 (from J702 to J705)

WM_DEV_WMP150_UGD_001 Rev 002 August 16, 2010 16
WMP Development Kit User Guide
General Description
SIM (from J401 to J405)
USB (from J301 to J305,signals and power supply)
Power supply of the Development Kit interfaces (from J605, all components except the
module (for more information, see §7))
Power supplies from the module
BUZZ-OUT signal (with J603)
FLASH-LED signal (with J602)
3.3. RoHS Compliance
The WMP module and the Development Kit board are compliant with RoHS (Restriction of Hazardous
Substances in Electrical and Electronic Equipment) Directive 2002/95/EC which sets limits for the use
of certain restricted hazardous substances. This directive states that “from 1st July 2006, new
electrical and electronic equipment put on the market does not contain lead, mercury, cadmium,
hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE)”.
The units which are compliant with this directive are identified by the
RoHS logo on their label.

WM_DEV_WMP150_UGD_001 Rev 002 August 16, 2010 17
4. External Board Connector (J1100)
4.1. Module Signals
Most of the modules signals are connected to the external board connector (J1100) and are available
via test points (TP) on the center of Development Kit. The J1100 connector pin out is listed below.
The other signals on J801 (related to memory interface) are described in section5).
For further information about the module signals and multiplexing, refer to document [1].
