Circuit Descriptions ENERNET Corporation Confidential The RF transceiver in ENERNET products is based on RF Monolithics P/N TR1000, which contains an amplitude modulated, SAW-based, fixed frequency transmitter, and a “sequenced” TRF receiver (see their documentation for circuit details). Support component selection was based on RFM reference designs and application note, ASH Transceiver Designer’s Guide. A single resistor controls power level; the remaining support components control baseband parameters like receive threshold levels, bandwidth and AGC. RF transceiver circuitry in ENERNET products is virtually identical (see figs. 1-3). Thermostat 10200 contains a power switch, Q2, to reduce quiescent battery consumption. This switch, controlled by microcontroller U3, turns communications processor U6 and RF transceiver U1 on and off. Conversely, Remote Control Node (RCN) products, 10300, 10500, 12200 are continuously powered from a line-based supply. Thermostat and RCNs both contain a communications processor, which formats data into a balanced differential Manchester-coded, 9.766 kb/s stream applied to the transceiver TXMOD pin through level adjust resistor. Receive data is translated to 5 volt logic levels for all products except the 12200, which operates entirely on 3.3 volts. The communications processor keys the transceiver chip with a PTT signal. In the 10200 Thermostat, data processing and user interface is performed by a dedicated microcontroller U3, which contains crystal controlled oscillators on 5.0 MHz and 32 kHz. It supplies 5 MHz clock signal to communications processor U6 through clock switch Q3. In all of the RCN products, the communications processor itself runs data processing and user interface algorithms, and has its own 5.0 MHz crystal oscillator. Differences between the RCN products is power supply type and application I/O capacity. The 10300 Plug Load RCN is a self-contained, single channel line voltage switch with a NEMA standard power plug and receptacle. The 10500 Line Voltage J_BOX RCN is a single channel, 110-240 volt product with 0.5 A pilot duty solid state switch output. The 12200 PTAC/FC-24 RCN is a 6 channel, 24 VAC control.

The UUT was transmitting a test signal during the testing. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-2003 using a HEWLETT PACKARD spectrum analyzer with a pre-selector. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100KHz and the video bandwidth was 300KHz up to 1.0GHz and 1.0MHz with a video BW of 3.0MHz above 1.0GHz. The ambient temperature of the UUT was 74.3oF with a humidity of 69%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m POWER LINE CONDUCTED INTERFERENCE: The procedure used was ANSI STANDARD C63.4- 2003 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10kHz with an appropriate sweep speed. The ambient temperature …
