Getting Started
This manual is for Zoom model 4575 and its uncased version, model 4576. These
ZoomCelltm modems use the Huawei MU609 LGA module and have a top downstream
speed of 14.4 Mbps. The cased model comes in a rugged aluminum case and includes a
power cube, 3 antennas (main, diversity, and GPS), and a printed Quick Start. The
cased model is normally your best choice for initial test and use of the MU609-based
modem, and the cased model may be a good choice for integration into a particular
system. Because the uncased model is designed for lower cost and volume applications,
it does not come with a power cube or antennas.
The Quick Start section below repeats much of the information in the Quick Start flyer of
Zoom Models 4575 and 4576. The Table of Contents shows interesting topics covered in
this manual.
For details about Model 4575 and 4576 hardware, including power specifications and
details about the modem’s input/output ports, please see the Model 4575 datasheet at
www.zoomtel.com/4575.
Because Model 4575 and 4576 use the PTCRB certified Huawei MU609 LGA module,
you can also find a lot of useful information from Huawei’s documentation, including
information about the command set for controlling Models 4575 and 4576. A link to this
documentation is available at www.zoomtel.com/4575support .
Quick Start
This Quick Start describes how to plug a micro SIM card into the SIM slot of the modem,
connect the antennas, power up the modem, and then use the USB port of a Windows
computer to connect to the Internet. It is intended as an example to get you up and using
the modem quickly. If you do not want to try this you can skip this section. There are
many other ways to use the modem, and these are described in the following chapters.
4

Figure 1

Plugging a micro SIM into the micro SIM slot of the modem
First unscrew and remove the case’s SIM cover (Model 4575 only). Plug in a micro SIM
at the location shown in Figure 1. The micro SIM can be obtained from AT&T or another
modem-compatible service provider. After the micro SIM is in place, model 4575 users
should put the SIM cover back in place and screw it in.
Connecting the antennas
Before installing your cellular antennas, you must first screw the two metal antenna
wires into the antenna bases. Next, screw the 2 antennas into the SMA connectors
labeled Main and Aux as shown in Figure 1. If your unit did not come with cellular
antennas or if you want to use your own cellular antennas, they should meet the
specifications shown in Chapter 8 Hardware Specification. If you are using GPS, screw
the GPS antenna into the GPS SMA connector.
Connecting the power cube to the modem
If your modem comes with a power cube, you can plug that between a wall outlet and the
Power connector shown in Figure 1.
5

You also have the option of supplying power for the modem using the Modem’s header.
If you prefer to use the modem’s header, DON”T USE THE POWER CUBE AT THE
SAME TIME. For more information about using the modem’s header to power the
modem, please see Chapter 7 - Using the Modem’s Header for more information.
Connecting the Modem to the Internet using a Windows Computer
In this example we install a USB driver onto a Windows 7, 8, or 10 computer, then use
dial-up networking to connect to the Internet. When connected this way, the modem uses
the Windows built-in protocol stack and not the TCP/IP stack built into the modem.
This section is intended to be used as an example to let you use the modem quickly. If
you do not want to install the modem in Windows, you can skip ahead to Chapter 2 for
more detailed instruction for installing your modem.
Installing the Windows USB Driver
1Download the Windows USB driver for your modem from
www.zoomtel.com/4575support. Unzip the file and store it in a folder on your
desktop.
2Inside that folder, double click on DriverInstall.exe to install the USB driver. The
driver installs in the background in roughly 30 seconds. If the This program
might not have installed correctly dialog box appears, you can ignore this
message and click This program installed correctly.
3Plug one end of a USB cable into the USB port of your computer and plug the
other end of the cable into your modem’s USB port.
Setting up the Modem for your Network
Before you can connect to the Internet through Windows, you will need to register your
modem with your cellular network. To do this, open up a terminal program on your
computer to talk directly to your modem. If you do not have a terminal program on your
PC, there are several open source programs such as Tera Term, Putty, or RealTerm that
you can download and use if you obey their terms of use.
1To check what port your modem is installed on, go to the Control Panel, click on
Phone and Modem, and select the Modem tab. The modem will be installed as
a Huawei Mobile Connect Modem and the com port number will be listed next
to the modem.
6

2Set your terminal program to use this com port number and set the serial port to
460,800 bps.
3To register your modem, enter the command AT+CGDCONT=1,“ IP”, “<APN>”
Where <APN> is the Access Point Name associated with your SIM card. For
example to register on an AT&T network using the AT&T APN Broadband you
enter the following command.
AT+CGDCONT=1,”IP”,”Broadband”
The terminal program should then show OK as the modem’s response.
4Next, check that the modem is attached by entering the command AT+CGATT?
The modem should respond:
+CGATT: 1
OK
5If the modem responds with +CGATT: 0, then it is not attached to the network
and you must manually attach it by entering the command AT+CGATT=1.
Connecting to the Internet
1To connect to the Internet, you need to set up a Dial-up connection. To setup a
connection, follow the steps for your OS.
Window 7: Go to the Control Panel / Network and Sharing Center and click on
Setup a New Connection.
Windows 8.1/8: From the charms bar, select Settings / Control Panel / Network
and Sharing Center and click on Setup a New Connection.
Windows 10: From the Start button, select Settings / Network and Internet /
Dial-up then click on Setup a New Connection.
2Follow the prompts to set up your new dial-up connection. When you come to the
screen that asks you to enter the phone number, user name, and password,
enter *99# as the phone number and leave the user name and password boxes
empty.
3Click Connect to connect to the Internet. Once connected, you may open your
browser and go to a familiar Web site. If it works, Congratulations! Your
Installation is complete. If your modem is NOT working please see Appendix B - If
You Need Help.

Installing the ZoomCell Modem
Chapter 1 provided a quick example to allow you to test the modem using Windows
dial-up networking. This chapter includes more detailed information for using the modem
with either the serial port or USB port, and provides information for using different
Operating Systems with the modem.
Installing your Hardware

If you have not yet installed your hardware by either following the steps in the quick start
or in Chapter 1, please follow the steps below.

Plugging a micro SIM into the micro SIM slot of the modem
ZoomCell Modems use a 3FF SIM card, which is typically called a micro SIM. The
modem supports 1.8v and 3.0v SIM cards and will automatically detect which type you
are using. If you plan to use your modem in extreme temperature conditions, we
recommend that you get a SIM card rated for industrial temperatures.
Compatible SIM cards can be obtained from either AT&T, T-Mobile or other providers
that offer service compatible with your ZoomCell modem. For a list of compatible
providers please see www.zoomtel.com/m2mproviders.
To install your SIM card, first unscrew and remove the case’s SIM cover (Model 4575
only). Plug in a micro SIM at the location shown in Figure 1. After the micro SIM is in
place, model 4575 users should put the SIM cover back in place and screw it in.
