2. Connect serial cable between your PC and the port labeled “ Serial port to Cellular modem”.

3. Provide power to the Multitech developer board using the provided power supply. Turn the power switch ON.

4. Open a terminal emulation in the PC ( Hyperterminal, Teraterm, etc). Configure the terminal with the following settings:

Baud Speed = 115200

Data Bits = 8

Parity = None

Stop Bits =1

Flow Control = Hardware

• You should be able to send the following AT commands to the modem:

AT+GMR <enter>

AT+GMM <enter>

AT+GMI <enter>

The complete AT command guide for the modem is available at the following link:

Accessing the modem through the Wi-Fi/Bluetooth controller card.

There is a controller card that will handle the WIFI and Bluetooth features in the MTPCIE modem. This card can also provide access to AT commands to the modem.

These are the steps to access the modem using the controller card;

1. Connect a serial cable between you PC and the port labeled “Serial Port toMT100EOCG”

2. Open a terminal emulation in the PC ( Hyper-terminal, Teratem, etc).

Configure the terminal with the following settings:

Baud Rate : 115200

Data bits : 8

Parity : None

Stop bits : 1

Flow Control : None

5. Turn the ON power in the developer card. You should see some information on the terminal while the controller card goes through the boot process. Wait until you get the login prompt and logon into the device with the following credentials:

Username : root

Password : root
