After configuring one modem, use the template feature to copy that device configuration to other devices. Tip: Configuration steps and examples in this guide use ACEmanager. Rev 1.0 Dec.11 13 AirLink GX400 for AT&T HSPA+ User Guide ACEview ACEview is an efficient status and connection monitoring application with a low-

profile, easy to read interface. Connecting to AT&T The GX400 uses AT&T as an ISP (Internet Service Provider) to connect you to the Internet. Steps of a Connection 1. When your AirLink GX400 is powered on, it automatically searches for cellular service using HSPA+. 2. Your AirLink GX400 establishes a communications link to the AT&T network with the radio module. 3. When your AirLink GX400 has received its IP address from AT&T, a connection to the Internet or the cellular network is also available for computers or other devices connected directly to the AirLink GX400. The AirLink GX400 will perform routing for all internet traffic to and from the computers or other end devices. With the AirLink GX400 in Ethernet Public mode, only one device connected to the Ethernet port will receive the public IP address which is the one provided by the cellular network. In Ethernet Private mode, with a hub or switch connected to the Ethernet port, the AirLink GX400 will provide NAT for a range of computers or other devices connected to the switch or hub and Internet access to all of them. Dynamic vs. Static IP Addresses There are two types of addresses on networks: dynamic and static.

Dynamic addresses are assigned on a need to have basis. Your AirLink GX400 might not always receive the same address each time it connects with AT&T. Static addresses are permanently assigned to a particular account and will always be used whenever your AirLink GX400 connects to the Internet. The IP address will not be given to anyone else.

Most ISPs (cellular included) use dynamic IP addresses rather than static IP addresses since it allows them to reuse a smaller number of IP addresses for a large number of customers. A dynamic IP address is suitable for many common Internet uses, such as web browsing, looking up data on another computer system, or other client functions (such as data only being sent out or only being received after an initial request). Tip: If your account with AT&T includes a dynamic IP address and you need a static IP, please consult your AT&T Representative for more information about changing your account for static IP support. 14 2140712 Introduction to the AirLink GX400 If you need to contact your AirLink GX400, a device connected to the AirLink GX400, or a host system using the AirLink GX400 from the Internet, you need to have a known IP (such as one which is static) or domain name (an IP address which is converted by a DNS server into a word based name). If you have a dynamic IP address for your modem, you can use a Dynamic DNS service (such as IP Manager) to translate your IP address into to a domain name. Caution: If you want to connect remotely to your AirLink GX400 using TCP/IP, the IP address given to your modem by AT&T cannot be a private or internal IP address (such as a special private network) unless you are on the same network or inside that networks firewall (as with frame relay). Communication Many of the GSM Networks have been expanded to HSPA+. HSPA+

HSPA+ (High-Speed Packet Access +) is an enhanced version of HSPA cellular technology defined by the 3rd Generation Partnership Project (3GPP) Release 7 UMTS specification for Mobile Terminated Equipment. Using improved modulation schemes and refined data communications protocols, HSPA+ permits increased data rates. Theoretical speeds are 5.76 Mbits/s uplink and 21.1 Mbits/s downlink. HSPA (High-Speed Packet Access) is a cellular technology which most closely resembles a broadband synchronous connection. The upload and download speeds are maximized to provide a faster throughput, reaching speeds up to 2.0 Mbit/s for the uplink and 7.2 Mbit/s for the downlink. HSPA+ falls back to HSPA, UMTS, EDGE, or GPRS (in order of precedence). This feature allows you to have seamless connectivity no matter where your AirLink GX400 is. UMTS UMTS (Universal Mobile Telecommunications System) supports up to 1920 kbit/s data transfer rates, although most users can expect performance up to 384 kbit/s. A UMTS network uses a pair of 5 MHz channels, one in the 1900 MHz range for uplink and one in the 2100 MHz range for downlink. EDGE EDGE (Enhanced Data rates for GSM Evolution) provides end-to-end packet data services with an enhanced connectivity building on GPRS technology and using the established GSM networks. EDGE provides higher transmission rates and better transmission quality for data than GPRS. EDGE can carry data at speeds typically up to 384 kbit/s in packet mode. Rev 1.0 Dec.11 15 AirLink GX400 for AT&T HSPA+ User Guide When EDGE is not available, your AirLink GX400 will fall-back to GPRS for the connection to AT&T to provide continued connectivity. GPRS General Packet Radio Service (GPRS) is packet-switched with many users sharing the same transmission channel, but only transmitting when they have data to send. This means that the total available bandwidth can be immediately dedicated to those users who are actually sending at any given moment, providing higher utilization where users only send or receive data intermittently. GPRS provides speeds of 3070 kbps with bursts up to 170 kbps. Connection Methods You can connect the AirLink GX400 to a USB or an Ethernet (RJ45) port on a computer. When connected to one of these ports, the AirLink GX400 behaves like a network card. USB The AirLink GX400 is equipped with a USB port which increases the methods by which you can send and receive data. The USB port can be set to work as either a virtual Ethernet port or a virtual serial port. A driver installation is required to use the USB port in either mode. It is recommended that you use a USB 2.0 cable with your AirLink GX400 and connect directly to your computer for best throughput. Virtual Serial Port The AirLink GX400 supports one virtual serial port over USB. This VSP can be used to send AT commands or to run many serial-based applications such as HyperTerminal. Networking IPsec The IP protocol that drives the Internet is inherently insecure. Internet Protocol Security (IPsec), which is a standards-based protocol, secures communications of IP packets over public networks. IPsec is a common network layer security control and is used to create a virtual private network (VPN). 16 2140712 Introduction to the AirLink GX400 The advantages of the IPsec feature includes:

Data Protection: Data Content Confidentiality allows users to protect their data from any unauthorized view, because the data is encrypted (encryption algorithms are used). Access Control: Access Control implies a security service that prevents unauthorized use of a Security Gateway, a network behind a gateway or bandwidth on that network. Data Origin Authentication: Data Origin Authentication verifies the actual sender, thus eliminating the possibility of forging the actual senders identifi-

cation by a third-party. Data Integrity: Data Integrity Authentication allows both ends of the communi-

cation channel to confirm that the original data sent has been received as transmitted, without being tampered with in transit. This is achieved by using authentication algorithms and their outputs. The IPsec architecture model includes the Sierra Wireless AirLink gateway as a remote gateway at one end communicating, through a VPN tunnel, with a VPN gateway at the other end. The remote gateway is connected to a Remote network, and the VPN is connected to the Local network. The communication of data is secure through the IPsec protocols. Figure 1-5: IPsec Architecture GRE GRE (Generic Routing Encapsulation) tunnel is used to carry non-IP packets through an IP Network. Non-IP packets that are send over the GRE tunnel need to be first encapsulated. Hence, ALEOS is used to configure and encapsulate non-IP packets and transmit over IP through the GRE tunnel. Rev 1.0 Dec.11 17 AirLink GX400 for AT&T HSPA+ User Guide Applications Events Reporting Events Reporting is the AirLink modems new software feature provided via ACEmanager. It allows the users to generate reports from the events that take place. Event Reporting Protocol is an intuitive embedded protocol, which automatically formats the messages based on an event trigger. The messages generated are then reported to the remote server.

Antenna installation should provide for at least a 20 CM separation from the operator. Antennas selected should not exceed a maximum gain of 4.55 dBi in Cellular Band and 2.85 dBi in PCS band under any standard installation configuration. In more complex installations (such as those requiring long lengths of cable and/or multiple connections), it is imperative that the installer follow maximum dBi gain guidelines in accordance with the radio communications regulations of the Federal Communications Commission (FCC), Industry Canada, or your countrys regulatory body (if used outside the US). Your AirLink GX400 will work with most cellular antennas with an SMA connector. Connect the primary antenna or primary RF cable directly to the antenna connector on the back of the AirLink GX400. Tip: When using a cable to an antenna placed away from the device, minimize the length of your cable. All gain from a more advantageous antenna placement can be lost with a long cable to the device. 28 2140712 Installing and Activating the AirLink GX400 GPS Antenna The AirLink GX400 will work with most standard active GPS antennas. Connect the GPS antenna or cable directly to the threaded SMA connector. If mounting the GX400 in a vehicle, the less the cable is wrapped and bound together, the better it will perform. Place it on the roof, on the dash, or on a rear panel where it has a greater than 90 angle view of the sky. There are three antenna mount options:

The Ethernet port of the AirLink GX400 can be connected directly to a computer or other Ethernet device with either a cross-

over cable or a straight-through cable. The Ethernet port on the AirLink GX400 is auto-sensing, and it will auto-detect the speed of the connecting device for 100baseTX or 10baseT. Serial Port Figure 3-6: Serial cable The serial port of your AirLink GX400 can be connected directly to most computers or other devices using a standard straight through cable. If you have a DCE device, you will need a null device or null device cable. All local GPS (UDP encapsulated) reports will come over the Ethernet connection. The serial port is available for both initial product configurations and debugging. Rev 1.0 Dec.11 31 AirLink GX400 for AT&T HSPA+ User Guide USB OTG Port Figure 3-7: USB Micro-A connector cable The CPU OTG port operates in device mode; when the port is unused, the AirLink GX400 operates in device mode. If a Micro-B plug is inserted into the port, AirLink GX400 operates as a self-powered device: it will not draw any current from the USB. If a Micro-A plug is inserted, the AirLink GX400 can operate in host mode and supply power to the device that is plugged into. At this time, however, USB host capability is a future ALEOS enhancement. Your AirLink GX400s high-speed (480 Mbps) USB 2.0 port can be directly connected to computers or other devices using a standard USB 2.0 cable. If the computer or device you are connecting or the cable is not rated for high-speed, the device will communicate at a reduced speed to match. When it is connected to a computer in device mode, the USB port should be seen as either a COM port or Ethernet port after the applicable driver is installed and configuration has been enabled. The port is, by default, a virtual Ethernet port. LED Operation Four LEDs are visible from the front and top of the AirLink GX400.

The device can also be configured to change its power mode in order to conserve power. These features can be configured to your needs. Capturing External Events The AirLink GX400 is equipped with an I/O port interface which includes 1 low power timer enable input and 1 digital I/O. These may be connected to sensors and switches to monitor status and remotely control equipment. AirLink GX400 board supports a low power timer enable input pin and a digital I/O pin which are connected to the CPU processor. The I/O signal comes in from the power connector, through a PolySwitch resettable fuse, and ties into the CPU pins with protection circuitry. Digital Input Digital Input can be used in two different modes: the switch mode or the voltage sensing mode. Digital Input Contact Closure Digital I/O Ground Figure 5-1: Digital Input Contact Closure The switch mode senses contact closures. The digital input can report either an open or closed state, and can be wired to a ground signal via a switch. When the switch is open, the input reads 3.3V. When the switch is closed, the input reads OV. Rev 1.0 Dec.11 43 AirLink GX400 for AT&T HSPA+ User Guide Counting pulses or other electronic events Examples of using the input with a switch to ground:

When a door or other latch is opened or closed

When a gauge reaches a certain point

When a container fills or empties

When a switch or valve is opened or closed

When the tow bar is raised or lowered

When the trunk of a vehicle is opened or closed

When the ignition is turned on or off. Connected to a sensor, the level of fuel in a vehicle Digital Output Digital Output of open collector design is capable of driving an external device such as a pull-up resistor or relay. (For example, a relay could be connected between the output pin and an external voltage.) The voltage on the relay cannot exceed 30V. The digital output pin can handle up to 150mA. Setting off an alarm or siren Triggering a process to start on another device Examples of using the digital output with an external relay or pull-up resistor:

Opening the vehicle's trunk or doors. Figure 5-2: Digital Output 44 2140712 Inputs, Relay Outputs, and Power Status Power Modes and Information AirLink GX400 low power modes can be configured using ACEmanager

(Default: no power modes). You can switch power modes in response to specific events, such as when the voltage to the device drops below a configured threshold or when ignition is turned off, in order to conserve battery life. The standby state, low power mode, will prevent the device from draining the battery while allowing the device to quickly power up to regular operation when it is needed. The GX400 has two main power states when low power mode is enabled in ACEmanager and whether the low power mode input signal is low or high:

1. When the low power mode input line goes low (tied to switched power), it can 2. be used to completely power down the GX400 (Off, 0mA) after the program-

mable timer expires or the input voltage falls below a programmable threshold If low power mode input is kept on (tied to unswitched main power), it can go from a full power state (180mA - 300mA) to low power mode (35mA) using either the programmable timer or when the main input voltage drops below the programmable threshold. In addition, the GX400 can be set to wake up at a periodic interval with a user-defined duration if it is desired to send a message at the same time every day. LPM = 0 and Delay Period Expired or Voltage Threshold Crossed or Periodic Timer Inactive Normal LPM = 1 and Delay Period Expired or Voltage Threshold Crossed or Periodic Timer Inactive OFF LPM = 1 LPM = 1 and Voltage Threshold Crossed or Periodic Timer Active Low Power LPM = 0

* LPM = Low Power Mode Input Signal Figure 5-3: Low Power Mode Diagram Rev 1.0 Dec.11 45 AirLink GX400 for AT&T HSPA+ User Guide Power Effect on Device State Once the transition from powered on to low-power mode starts, the device will change state to AT mode. This results in the current mode being gracefully terminated. For the brief period when the device is preparing for low-power mode, the device will remain in AT mode. At that time, it won't auto-answer, ATD will fail, etc. Once low-power mode is entered, the device will then discard any data received on the host port. When the device is activated from the low-power mode, the same activity occurs as power on. The device starts in AT mode, and after 5 seconds will enter the default start-up mode as it is configured for the device. Monitoring Power-In Voltage The current status of the power-in voltage can be monitored in ACEmanager. 46 2140712 6: Regulatory Information Regulatory Information Federal Communications Commission Notice (FCC)
