EZ-Star is based on a combination of Global Data’s standard StarPoint communications platform and the Marwell family of meter socket adapters. The resulting product provides an economical AMR solution that rivals under the glass solutions for cost of installation and surpasses under the glass solutions for ease of maintenance and ease of upgrade. Designed to operate on networks utilizing the CDMA and/or 1XRTT Packet Radio Service, EZ-Star supports bi-directional data communication which may be originated by either the meter or host application. 1.2 NETWORK MODES The CDMA network is designed to support digital voice and data transmission. Data transmission can occur as either circuit switched data, or with the 1XRTT overlay, as packet data. Many traditional host applications communicate via modem to endpoints through analog cellular connections or public switched telephone networks (PSTN). Utilizing the CDMA circuit switched data mode, these applications can seamlessly switch to digital cellular connectivity. Host applications capable of communicating via Internet Protocol (IP) can utilize 1XRTT as a means of communicating with endpoint hardware. In 1XRTT mode, data remains in IP packet format from the host application through the carrier network, to the endpoint communication device, and back. 1.3 FEATURES • Dual Frequency Bands – 800Mhz (Cellular) and 1900Mhz (PCS) • Wide range AC power supply • Multiple data modes - Circuit Switched data and 1XRTT packet data • Thermal Protection • AMR Meter Direct Connection – RJ-11 jack accepts the standard RS-232 option board cable provided with General Electric, Elseter (ABB) and Landis + Gyr (Siemens) meters. • Remote Reprogramming – A smart-change feature allows for remote reprogramming of the device parameters without dispatching personnel to the remote location. 2 THEORY OF OPERATION The CDMA/1XRTT networks support two methods of data transmission: circuit switched and packet switched. In circuit switch mode, CDMA provides an error corrected data path through the network. Because of the error correction characteristics, applications must be prepared for lower throughput and higher latency characteristics that are similar to those experienced on a packet network. In circuit switched mode, modem banks in the CDMA network act as the gateway for all inbound and outbound data traffic. These modems communicate with the customer’s host-application modem and deliver a digital data stream into the CDMA network where it is then delivered to the endpoint device via an 2 error correcting protocol. In 1XRTT packet based communications, the customer’s host application communicates with the CDMA network via an IP connection. The 1XRTT network delivers packet data directly to an endpoint device such as EZ-Star. The EZ-Star contains TCP/IP protocol support so that standard asynchronous meters may be attached to the 1XRTT network. Various protocol layers within the EZ- Star may be disabled to accommodate meters that are IP capable. 3 ARCHITECTURE The EZ-Star integrates multiple components into a compact rugged design. These components work together to provide CDMA/1XRTT communications optimized for AMR applications. The components include an RS-232 serial interface, a micro controller with onboard memory, and a CDMA/1XRTT radio. 3.1 SERIAL INTERFACE The RS-232 serial interface may be configured for direct connection to most electric meters by setting jumpers on the EZ-Star circuit board. A quick connect RJ-11 is provided for connections to electric meters manufactured by General Electric, Elster, and Landis + Gyr. 3.2 MICRO CONTROLLER The Micro Controller provides a standard feature set including configuration control, diagnostic tools and protocol support. Global Data firmware is designed to optimize network efficiency by controlling packet size, framing and latency. On board user expandable flash memory provides support for customized protocols. Standard memory included onboard the Micro Controller is 128Kb with over 115Kb available for customer customized protocol development. The device may be ordered with an optional 256Kb of flash memory in place of the standard 128Kb. 3.3 RADIO The CDMA/1XRTT Radio included in EZ-Star has been designed specifically for telemetry applications. This device has been tightly integrated with the Micro Controller and Serial Interface to provide dependable cellular service with standard interfaces. 3 4 MODULE INTERFACE AND CONNECTORS POWER SUPPLY, POWER “ON” LED SIGNAL QUALITY LED (SEE FIGURE 3 FOR DETAILS) FIGURE 1 INTERNAL ANTENNA SMA FEMALE CONNECTOR FOR EXTERNAL ANTENNA RS-232 RJ-11 JACK RS 232 CONFIGURATION JUMPERS (SEE FIG. 2 FOR DETAIL) FIGURE 2 LANDIS + GYR AND ELSTER JUMPER CONFIGURATION GE / KV2 JUMPER CONFIGURATION RS-232 JUMPER CONFIGURATION View from bottom of…

MPE Calculations FCC part 1.1310, Table 1 limits the power density for uncontrolled exposure to 1mW/ cm 2 for systems operating in FCC Part 22H and 24E. The distance, d(cm) from the antenna at which the power density, P d (mW/cm 2 ) is below this limit is calculated from the maximum EIRP, P t (mW) using the equation: P d = P t /(4 πd 2 ) Re-arranging for the distance at which the power density is 1mW/cm2 gives: d = √ (P t /(4 π)) Frequency Maximum Output Power (dBm) EIRP (mW) Pd at 20cm Calculated distance (in cm) where Pd < 1mW/ cm2 824-849 MHz 18 63.1 0.01255 2.24 1850 – 1910 MHz 25.8 380.2 0.0756 5.50 The minimum distance from the antenna that the power density is 1mW/ cm 2 and the calculated minimum distance is 2.24 cm (22H&RSS-129) and 5.5 cm (24E&RSS-133). This information is detailed in the user manual as follow: To satisfy FCC RF exposure compliance requirements for a mobile transmitting device, this device and its antenna should generally maintain a separation distance of 20cm or more from a person’s body.
