Attention: Technical Publications Dept. 472 Kato Terrace Fremont, CA 94539 Important Notice Because of the nature of wireless communications, transmission and reception of data can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant delays or losses of data are rare when wireless devices such as the AirLink Communications modem are used in a normal manner with a well-constructed network, the AirLink modem should not be used in situations where failure to transmit or receive data could result in damage of any kind to the user or any other party, including but not limited to personal injury, death, or loss of property. AirLink Communications, Inc., accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or received using the AirLink Communications modem, or for failure of the AirLink Communications modem to transmit or receive such data. Safety and Hazards Do not operate the AirLink Communications modem in areas where blasting is in progress, where explosive atmospheres may be present, near medical equipment, near life support equipment, or any equipment which may be susceptible to any form of radio interference. In such areas, the AirLink Communications modem MUST BE POWERED OFF. The AirLink Communications modem can transmit signals that could interfere with this equipment. Do not operate the AirLink Communications modem in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, the AirLink Communications modem MUST BE POWERED OFF. When operating, the AirLink Communications modem can transmit signals that could interfere with various onboard systems. The driver or operator of any vehicle should not operate the AirLink Communications modem while in control of a vehicle. Doing so will detract from the driver or operator's control and operation of that vehicle.

Introduction The GSM/GPRS wireless network combines the world’s leading wireless standard— the Global System for Mobile Communications (GSM)—with fast, packet-switched access to data networks such as the Internet. Providing this fast access is the General Packet Radio Service (GPRS). The AirLink GPRS modems are designed to operate in GSM/GPRS networks. Two data services are available in the GSM/GPRS networks: GPRS, a packet switched connection, and SMS, a short message service.. GPRS GPRS is an IP-based service that offers fast, packet-switched access to data networks such as the Internet. It is a mobile service that improves the peak-time capacity of a GSM network. GPRS gives packet-switched access over GSM to external data networks with high …

Page 1 October 14, 2003 G3110 G3210 G3310 Feature Comparison 1 Introduction The Redwing [G3110], Raven [G3210], and PinPoint [G3310] GPRS modems are designed to operate in GPRS networks. The Redwing is intended to be used with intelligent devices that contain a TCP/IP protocol stack, and use the Redwing only as a GPRS network access device. The Raven and PinPoint modems add an ARM processor and a real-time clock which enhances the capabilities of these modems. The Raven can interface with a large number of different devices and provide the data communications functions necessary for the devices to operate over a GPRS network. The PinPoint contains the same functionality as the Raven, and adds a GPS module to provide location information. 2 Overview of Common Features The GPRS modems share a number of common hardware features. The AirLink GPRS modems use the RIM OEM module, the 1902G, to implement the GSM/GPRS modem functions. AirLink mounts all the components for the modems in rugged enclosures which provide physical and electrical protection, and a wide range power regulator.

Page 5 October 14, 2003 2.4 RIM 1902G OEM Module RIM’s embedded OEM GPRS modem module, the 1902G, is used to provide the GSM/GPRS modem functions in the AirLink GPRS modems. 2.5 Voltage Regulators An efficient switching voltage regulator converts the 10 to 28 VDC input power to 3.6 VDC in the Redwing and 5.3 VDC in the Raven and PinPoint. A pair of linear voltage regulators regulates the 5.3 VDC to 3.3 and 3.6 VDC in the Raven and PinPoint. 2.6 Power Input Protection Power input over-current protection is provided by employing a 500 ma resettable PTC device that will open when the input current exceeds 500 ma. After a period of time, it will reset and conduct current again. A diode in the power input ground path protects against accidental reverse power connections. Current is blocked from flowing through the ground path to other external ground connections to the modem. Overvoltage protection is provided with a tranzorb connected across the power input lines. It will conduct the input voltage to ground if the input voltage exceeds 30V. A voltage monitor circuit will turn the voltage regulator on and off at levels sufficient to insure proper operation of th…
