1. This document illustrates the steps to communicate to the MTPCIE-H5-V-BW modem The device is mounted on a developer board that provides access to the PCIE Board through a serial interface or the Bluetooth/WIFI controller card. The Following slide describes the different antenna interfaces and the serial port connections of the developer board. 1Proprietary & Confidential | © 2012 Multi-Tech Systems, Inc.

3. 1. Accessing the Modem through the serial port. 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 AT+GMM AT+GMI The complete AT command guide for the modem is available at the following link: ftp://ftp.multitech.com/.ext/customer/Cetecom/H5%20AT%20Command%20Guide%20%20-%20S000528A.pdf 3Proprietary & Confidential | © 2012 Multi-Tech Systems, Inc.

4. 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 to MT100EOCG 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 4Proprietary & Confidential | © 2012 Multi-Tech Systems, Inc.

5. 6. At the # prompt type the word reboot (without the quotes). This will force the card to do a warm boot. 7. Wait until the card finishes booting and logon into it one more time using the same credentials as before ( Username: root, Password: root). 5Proprietary & Confidential | © 2012 Multi-Tech Systems, Inc.
