Important
Notice
Safety and
Hazards
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.
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.
Limitation of
Liability
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.

locations on the board, see Figure 2-2 on page 8 and Figure 2-3 on page 9.
2.2.1.1 IoT Expansion Card
mangOH Red includes one IoT Expansion Card slot (IOT0), which has an IoT Connector (CN306) that connects to
the CF3’s signals as detailed in Table 2-2.
This slot provides full support for the IoT Expansion Card specification.
By default, specific signals are enabled when the mangOH Red boots. For additional information, including default
configuration and how to temporarily change it, see IoT Connector Interfaces on page 31.

2.4 CF3 Module Signals
This section describes how CF3 module signals connect to the platform hardware (described in mangOH Red
Hardware Components on page 12).
Important: CF3 module signal availability depends on the module type—some modules may not implement certain
Extension signals from the CF3 specification.
2.4.1 ADC
The mangOH Red supports four CF3 module ADC (Analog to Digital converter) signal sources (ADC0-ADC3).
The ADC signals connect to the following sources, as shown in Figure 2-5:
•
ADC0—IoT Connector 0 (CN1000, slot IOT0), pin 20
•
ADC1, ADC2—Low Power I/O (CN312), pins 4 and 5
•

Notes:
•
Six GPIOs connect to the IoT slot (for card detect, card reset, and four for use as GPIOs).
•
One GPIO (GPIO32) connects to the NINT (active low interrupt) output signal from a GPIO expander (U1004).

2.8 Power Management
The mangOH Red has two primary power supplies (CF3 USB connector and CONSOLE USB connector), and a
rechargeable backup battery power supply option.
Figure 2-22 illustrates these power supplies, their voltage/current specifications, and how they supply various
components on the mangOH Red platform.
A multi-function switch (SW401) controls some power-related features (see Multi-switch (SW401) on page 15),
including:
•
Pin 1 (PWR_ON)—Enable/disable CF3 module’s POWER_ON_signal

•
Pin 3 (VCC_3V7_ULPM)—In ULPM, enable/disable power to accessories (CF3 module always receives
power)
•
Pin 5 (BATT_TS+)—Enable/disable backup battery charging
