INSTALLING AND USING THE DEVICE Installing and Using the Device Installing the Device 1. 2. 3. 4. Connect a suitable antenna to the antenna connector. If you are using the serial version of this device: Connect the DB9 male connector (9-pin) of the RS-232 cable to the RS-232 connector on the device, then connect the other end to the serial port on the other desired device. Screw-on the power lead from the power supply module into the power connection on the device.
INSTALLING AND USING THE DEVICE 5. To have the device enter sleep mode, set DTR to inactive (off) on the RS-232 interface. The clear to send (CTS) signal is off when the device is in sleep mode. USB Cable Recommendations If your device has a USB connector, to avoid enumeration or power issues: ■ Use a high speed USB cable that is as short as possible. ■ Use a well shielded cable with at least 24 AWG wire pair for power/ground and 28 AWG wire pair for data lines.
ANTENNA AND ACTIVATION INFORMATION Antenna and Activation Information Antenna The antenna intended for use with this unit meets the requirements for mobile operating configurations and for fixed mounted operations, as defined in 2.1091 and 1.1307 of the FCC rules for satisfying RF exposure compliance. If an alternate antenna is used, consult user documentation for required antenna specifications.
ANTENNA AND ACTIVATION INFORMATION process for adding devices to their network. Refer to Multi-Tech's Cellular Activation site http://www.multitech.com/activation.go for step-by-step instructions on activating your cellular modem with your service provider. Device Phone Number Every device has a unique phone number. Your 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.
USING LINUX Using Linux Shell Commands Testing Serial Ports To test the serial ports created by the driver, type in a shell: Note: Sending ATE0 is required, to avoid issues in the terminal output.

CONFIGURING AND COMMUNICATING WITH YOUR DEVICE Configuring and Communicating with Your Device Interacting with Your Device Overview This section describes how to use AT commands to interact with your device. Using terminal software such as Kermit, you can issue AT commands to communicate with and configure your modem. The AT commands let you establish, read and modify device parameters and help you control how the device operates.
CONFIGURING AND COMMUNICATING WITH YOUR DEVICE ■ Type AT and press Enter. If the device responds with OK, you are communicating with the device. Verifying Signal Strength To verify the device signal strength, enter: AT+CSQ The command indicates signal quality, in the form: +CSQ: , Where: Received signal strength indication.
CONFIGURING AND COMMUNICATING WITH YOUR DEVICE Checking Network Registration Before establishing a packet data connection, verify the is device registered on the network. To do this enter the network registration report read command: AT+CREG? If the device returns: +CREG: 0,1 The device is registered. If the device returns: +CREG: 0,2 The device is in a network searching state. Sending and Receiving Data Connecting Device to TCP Server as TCP Client 1.
