Preface
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.
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.

3: Electrical Specifications
The system block diagram in Figure 3-1 represents the EM7430
module integrated into a host system. The module includes the
following interfaces to the host:
•
Full_Card_Power_Off# — Input supplied to the module by the
host — active-low to turn the unit off, or active-high to turn the unit
on.
•
W_DISABLE1# — Active low input from the host to the EM7430
disables the main RF radio.
•
W_DISABLE2# — Active low input from the host to the EM7430
disables the GNSS radio receiver.
WAKE_ON_WAN# — Active low output used to wake the host when
specific events occur.
WWAN_LED# — Active-low LED drive signal provides an indication
of RADIO ON state, either WWAN or GNSS.
•
•
•
RESET# — Active low input from the host used to reset the
module.
•
•
•
•
Antenna — Three RF connectors (main (Rx / Tx), GNSS, and
auxiliary (diversity/MIMO/GNSS)). For details, see RF Specifications on page 41.
Antenna control — Four signals that can be used to control external
antenna switches — two for high band, and two for low band.
Dynamic power control — Signal used to adjust Tx power to meet
FCC SAR requirements. For details, see Tx Power Control on
page 57.).
Dual SIM — Supported through the interface connector. The SIM
cavities / connectors must be placed on the host device for this
feature.
•
SIM detect — Internal pullup on the module detects whether a SIM
is present or not:
· If a SIM is not inserted, the pin must be shorted to ground.
· If a SIM is present, the pin will be an open circuit.
•
USB — USB 2.0 and USB 3.0 interfaces to the host for data,
control, and status information.
The EM7430 has two main interface areas — the host I/O connector
and the RF ports. Details of these interfaces are described in the
sections that follow.

Power Supply
The host provides power to the EM7430 through multiple power and ground pins
as summarized in Table 3-2.
The host must provide safe and continuous power (via battery or a regulated
power supply) at all times; the module does not have an independent power
supply, or protection circuits to guard against electrical issues.

USB Interface
Important: Host support for USB 2.0 signals is required.
Important: Host support for USB 3.0 signals is optional, but if supported then the host
must also support fallback to USB 2.0.
The device supports USB 2.0 and USB 3.0 interfaces for communication between
the host and module.
The interfaces comply with the [9] Universal Serial Bus Specification, Rev 2.0 and
[10] Universal Serial Bus Specification, Rev 3.0 (subject to limitations described
below), and the host device must be designed to the same standards. (Note:
When designing the host device, careful PCB layout practices must be followed.)

Product Technical Specification & Customer Design Guidelines
USB Throughput Performance
This device has been designed to achieve optimal performance and maximum
throughput using USB superspeed mode (USB 3.0). Although the device may
operate with a high speed host, throughput performance will be on an “as is”
basis and needs to be characterized by the OEM. Note that throughput will be
reduced and may vary significantly based on packet size, host interface, and
firmware revision.
User-developed Drivers
Details for user-developed USB drivers are described in [4] AirCard / AirPrime
USB Driver Developer’s Guide (Doc# 2130634).
SIM Interface
The module supports up to two SIMs (Subscriber Identity Module) (1.8 V or 3 V).
Each SIM holds information for a unique account, allowing users to optimize their
use of each account on multiple devices.
Note: Host support for
SIM interface signals is
required.
The SIM pins (Table 3-4 on page 32) provide the connections necessary to
interface to SIM sockets located on the host device as shown in Figure 3-3 on
page 33. Voltage levels over this interface comply with 3GPP standards.
The types of SIM connectors used depends on how the host device exposes the
SIM sockets.

5.2.
34
When designing the remote SIM interface, you must make sure that SIM signal
integrity is not compromised.
Some design recommendations include:
•
Total impedance of the VCC and GND connections to the SIM, measured at
the module connector, should be less than 1 to minimize voltage drop
(includes any trace impedance and lumped element components — inductors,
filters, etc.).
•
Position the SIM connector 10 cm from the module. If a longer distance is
required because of the host device design, use a shielded wire assembly —
connect one end as close as possible to the SIM connector and the other end
as close as possible to the module connector. The shielded assembly may
help shield the SIM interface from system noise.
•
Reduce crosstalk on the UIM1_DATA and UIM2_DATA lines to reduce the risk
of failures during GCF approval testing.
•
Avoid routing the clock and data lines for each SIM (UIM1_CLK / UIM1_DATA,
UIM2_CLK / UIM2_DATA) in parallel over distances 2 cm — cross-coupling of
a clock and data line pair can cause failures.
•
3GPP has stringent requirements for I / O rise time (
