3 Chapter 1 Introduction 1.1 Purpose and Use The Receiver/Repeater 2A (FCC ID: MLLGL2RPT450) is a data link transceiver that is used for data transfer in Miltel’s radio system. The system is used for utility consumption readings collection system as well as for other applications such as in agricultural systems. This device is installed on-site by a professional field technician, thus it includes technical terms. The equipment is not to be installed by a non-professional individual that has not been trained and authorized. 1.2 System General Description The Receiver/Repeater 2A system is a computerized fully automatic radio device. It requires no human intervention after initial installation. The device acts as a store-and-forward radio relay. The Receiver/Repeater 2A operates as a receiver connected to a bases station or as a repeater that captures transmissions from a Miltel transmitter and, after validating the message, transmits the message again. When operating as a Repeater the device relays information from transmitters to a receiver that is connected to the base station which is typically implemented as a regional concentrator or as a standard PC. The concentrator/PC transfers the data to the central computer for data collection and for further analysis and reporting. When operating as a receiver, the device receives messages transmitted by Miltel transmitters or messages relayed by a repeater. The receiver can also send commands to any of the repeaters.
4 The Transceiver device is marketed as two models (as a receiver or as a repeater) and under three different commercial trade names (Speed Repeater 2A / Receiver 2A, Galaxy Repeater 2A / Receiver 2A and IrriWise Repeater 2A / Receiver 2A). The Transceiver device (both receiver and repeater) can be hooked up to a PC or to a laptop computer for programming purposes during system setup. 1.3 Theory of Operation The Receiver/Repeater 2A is the intermediate link in the wireless data collection system. It is an independent unit that operates as a repeater (radio relay) or as a collection device (receiver) linked to the base station. Figure 2-1 (see below) shows a typical installation of a Receiver/Repeater 2A unit. The device is powered by a 12 volt power supply or by a solar powered battery. The Receiver/Repeater 2A operates its radio receiver on a continuous basis until it receives a message from a nearby transmitter. After capturing the transmitted data message, it sends out an identical message which is forwarded to the Collector. Figure 1-1: Typical Installation (shown here with optional solar panel)
