Telematics Wireless Proprietary 1. Introduction The following document describes the technical specification of the ICON electricity meter transceiver (called ICON240V) for the USA market. The ICON meter is single phase class 2.0 ANSI C12.20 Electricity meter. The meter includes an AMR integrated module (call LC-TM) for RF communication. The ICON240C includes the following modules: ƒ Sensor board – measure the power consumption (KWh). The sensor board can be 240 volt type or 120 volt type, both 60 HZ frequency. ƒ Display board – display the reading with 9 digits LCD. ƒ LC-TM board for RF communication The LC-TM transmits the electricity meter readings via RF to a collecting unit. In addition specific parameters can be programmed via the RF link. The LC-TM operates at the 900MHz ISM band. The board consists of the following units: RF Transmitter & Receiver and a Microcontroller (plus simple Digital Logic), which control the operational modes of the unit. Note: The RF of the LC-TM board is entirely identical (same layout, dimensions, functionality & performance) to another board called LC-TMW (FCC-ID: NTAXMETER10). The Display board consists of the LCD display and the internal antenna (see paragraph 3.3) 1.1.
