Chapter 10 – Device Configuration

Before Using the Device

Before using the device:
Install any drivers. Refer to the separate driver installation guide for your device.
On your computer, install terminal software that can communicate with the device, such as HyperTerminal,
Tera Term, Kermit, or Putty.
Power up your device and ensure it is connected to your computer that issues AT commands.
Note: Wait 10 seconds after power-up before issuing any AT commands.
For additional information, refer to the AT command guide and any related documentation for your device. The AT
command guide describes command formatting, syntax, and other basic information.

Using Command Mode and Online Data Mode

Modems have two operation modes, command and online data. After power up, the modem is in command mode
and ready to accept AT commands.
Use AT commands to communicate with and configure your modem. These commands establish, read, and modify
device parameters and control how the modem works. The device also generates responses to AT commands that
help determine the modem's current state.
If the modem is in online data mode, it only accepts the Escape command (+++).
To send the modem AT Commands from terminal emulation software, set the software to match the modem's
default data format, which is:
Speed: 115,200 bps
Data bits: 8
Parity: none
Stop bit: 1
Flow control: hardware
To confirm communication with the device:
Type AT and press Enter.
If the device responds with OK, it is properly communicating.

Device Phone Number

Every device has a unique phone number. Your cellular service provider supplies a phone number when you
activate your account, or if your device has a SIM card, the phone number may be on it. Wireless service provider
implementation may vary. Consult with your cellular service provider to get the phone number for your device.
