Chapter 2 - Installation

Mobile PhoneTools

For initial configuration of your wireless device, Multi-Tech offers a Windowsbased mobile PhoneTools application.

To load mobile PhoneTools, click on the mobile PhoneTools icon on your MultiModem CD and follow the on- screen prompts.

Direct Modem Installation

To install the Wireless MultiModem directly into the computer's Windows OS so it is independent of the mobile Phonetools program, use the "Add Modem" command or equivalent for your OS. During this installation, you will need to browse to the MultiModem's INF file (using the “Have Disk” option in the installation process). This INF file is in the root directory of the Product CD.

Verifying Signal Strength

The Wireless MultiModem establishes a call if the signal is sufficiently strong. To verify the signal strength, do the following:

1.Using the Hyperterminal program at the computer to which the Wireless MultiModem is connected, type the AT command AT+CSQ. A value for the received signal strength will be returned.

2.Verify the result with the following chart:

Verifying Network Registration

In this procedure, you will verify that the Wireless MultiModem has been registered on the wireless network. To do so, you will use the common communications program Hyperterminal.

1.Using the Hyperterminal program at the computer to which the Wireless MultiModem is connected, type the AT command AT+CREG?

A value for the modem’s network registration status will be returned.

2.Verify the result with the following chart:

Note: If the modem is not registered, perform the procedure for Verifying Signal Strength to determine the strength of the received signal.
