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 IN

AIRPLANE MODE OR 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 IN

AIRPLANE MODE OR 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.

Introduction

The Sierra Wireless EM7590 is a compact, lightweight, wireless modem that provides

LTE, UMTS, and GNSS connectivity for M2M applications, notebook, ultrabook and

tablet computers over several radio frequency bands.

Accessories

A hardware development kit is available for MC-series modules. The kit contains

hardware components for evaluating and developing with the module, including:

• Development board

• Cables

• Antennas (Additional antennas may be required to support all bands.)

• Initial allotment of support hours

• Other accessories

• For over-the-air LTE testing, ensure that suitable antennas are used.

Required Connectors

Table 1-1 describes the connectors used to integrate the EM7590 PCI Express Mini

Card into your host device.

Table 1-1: Required host-module connectorsa

Connnector Type Description

RF cables • Mate with M.2-spec connectors

• Three connector jacks (I-PEX 20448-001R-081 or equivalent)

EDGE (52-pin) • Slot B compatible—Per the M.2 standard ([8] PCI Express

NGFF (M.2) Electromechanical Specification Revision 1.0), a

generic 75 pin position EDGE connector on the motherboard

uses a mechanical key to mate with the 67 pin notched module

connector.

•

Recommended part# AS0BC21-S30BB-7H

SIM • Industry-standard connector. Type depends on how host device

exposes the SIM socket

a. Manufacturers/part numbers are for reference only and are subject to change. Choose connec-

tors that are appropriate for your own design.

Power

Power Supply

The host provides power to the Sierra Wireless EM7590 through multiple power and

ground pins. The host must provide safe and continuous power at all times; the

module does not have an independent power supply, or protection circuits to guard

against electrical issues.

For detailed pinout and voltage/current requirements of this module, refer to the

EM7590 Product Technical Specification.

Module Power States

The module has four basic power states, as described in Table 2-1.

Normal

(Default state)

• Module is active

• Default state when VCC is first applied

in the absence of W_DISABLE_N

control

• Module is capable of placing/receiving

calls, or establishing data connections

on the wireless network

• Current consumption is affected by

several factors, including:

· Radio band being used

· Transmit power

· Receive gain settings

· Data rate

· Number of active Tx time slots

   

Low power

(‘Airplane mode’)

• Module is active

• Module enters this state:

· Under host interface control:

· Host issues AT+CFUN=0, or

· Host issues AT!PCOFFEN=0

(configures the modem to enter

low power mode when W_DIS-

ABLE_N is asserted), and then

asserts W_DISABLE_N

· Automatically, when critical

temperature or voltage trigger limits

have been reached
