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 1-1 (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.
