Scope and Objectives This document applies to the Nautilus Radio Module NRM-900-1. This manual is intended to be used by Nautilus engineers for designing the module into the host system. It shall also be used by the end user of the system for familiarization with the module’s operation and observing necessary precautions. 1 FCC Part 15 Statement This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. 2 Device Description 2.1 Purpose and target systems The NRM-900-1 is a UHF data transceiver module which is only approved for installation in devices under the control of the Grantee.” The module provides bi-directional half-duplex data link between two different parts of the system. The module is designed into the target system at Nautilus. Its operational parameters are fully controlled by the system firmware running on the host system. It is expressly prohibited to use the module in any system not designed and approved by Nautilus. It is also prohibited to alter the system’s firmware controlling the module in any way. 2.2 Module specifications 2.2.1 Power requirements The module shall be powered from a regulated DC power source compliant with the requirements listed in the following table. All target systems shall provide power source for the module that meets these specifications. Parameter Min Max Input voltage 3.22V DC 3.37V DC Input voltage ripple 10mVrms Current consumption 40mA DC 2.2.2 Control signals The module is fully programmed and controlled by the host system by means of the 4-wire SPI bus plus two status signals. The logic levels of these signals are defined as follows: - logic 0: from 0V to 0.3V; - logic 1: from 0.9 to 1.1Vcc, where Vcc is the power supply voltage. User Manual (2009) Rev 1.0 Page 5 of 6 19/11/09 Nautilus International Control & Engineering Ltd. Due to digital nature of operation, the module is not capable of producing over-modulation or excessive output power if these limits are violated, but it may be damaged and/or become inoperative. Maximum clock frequency of the SPI bus is 6.0MHz. Input impedance of the digital inputs is >1MOhm. Output impedance of the digital outputs is <100Ohm. Inputs are not allowed to float and must be properly driven by the host system at all times. 2.2.3 RF Specifications When installed into a Nautilus host system and properly programmed, the module shall provide the following RF parameters. Parameter Min Nom Max Frequency range, MHz 902.6 927.4 Channel spacing, kHz 400 Output power, dBm 9.0 10.0 12.0 Modulation bandwidth, kHz 500 Data rate, kbps 250 RX sensitivity for 1% BER -95 2.2.4 External connections The module has two 6-pin single-row connectors for power and control signals and one reverse-polarity SMA connector for the antenna. The module must be used only with the approved type of antenna. Antenna gain must not exceed 3dBi, otherwise operation may invalidate module’s approval. Pin functions are given in the following table: Pin # Pin function J1.1 GND J1.2 SPI MOSI – Data input to the module J1.3 SPI SCK – Serial clock input to the module J1.4 SPI MOSI – Data output from the module J1.5 GDO2 – Status output from the module J1.6 GND J2.1 +3VDC power input to the module J2.2 GND J2.3 GND J2.4 SPI CS – Module select input J2.5 GDO0 – Status output from the module J2.6 GND 2.2.5 Operating conditions The module mu…

DCN: 1034, Rev 2 RF Exposure (SAR) Test Date Sep. 03, 2009 Sample Number 764994 Tested By Jeremy LEE Use the barometric pressure reported at: http://www.theweathernetwork.com/weather/CABC0308 Test Limits FCC15.247 (i) Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines. See § 1.1307(b)(1) of this chapter. FCC1.1310 The criteria listed in table 1 shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in § 1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of § 2.1093 of this chapter. Further information on evaluating compliance with these limits can be found in the FCC’s OST/OET Bulletin Number 65, ‘‘Evaluating Compliance with FCC-Specified Guidelines for Human Exposure to Radiofrequency Radiation.’’ Included are calculations that determine that minimum distance from the transmitter antenna that will ensure an exposure limit at or below the guidelines given in Table 1 of Section 1.1310 for the general population. The formula for these calculations are taken from OET Bulletin 65, edition 97-01, August 1997; “Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields”.

DCN: 1034, Rev 2 Calculations Per Table 1 of Section 1.1310, the limit for General Population/Uncontrolled Exposure at 902 to 928MHz is f/1500 mW/cm 2 , where f is frequency in MHz. Per OET Bulletin 65, Edition 97-01, the formula for calculating power density is: S=P*G/4πd 2 with: Given E=√(30*P*G)/d and S=E^2/3770 where E=Field Strength in Volts/meter P=Power in Watts G=Numeric antenna gain D=Distance in meters S=Power Density in milliwatts/square centimeter Combining equations and rearranging the terms to express the distance as a function of the remaining variables yields: d=√ ((30*P*G)/(3770*S) Changing to units of Power to mW and Distance to cm, using: P(mW)=P(W)/1000 and D(cm)=100*d(m) yields d=100*√30*(P/1000)*G)/(3770*S)) d=0.282*√(P*G/S) where d=distance in cm P=Power in mW G=Numeric antenna gain S=Power Density in mW/cm^2 Substituting the logarithmic form of power and gain using: P(mW)=10^(P(dBm)/10) and G(numeric)=10^(G(dBi)/10) yields d=0.282*10^((P+G)/20)/ √S Equation(1) where d=MPE distance in cm P=Power in dBm G=Antenna Gain in dBi S=Power Density Limit in mW/cm^2 Equation (1) and the measured peak power is used to calculate the MPE distance.

DCN: 1034, Rev 2 Limits From §1.1310 Table 1 (B), S=1.0mW/cm^2 Results No non-compliance noted: Channel Frequency(MHz) Power Density Limit (mW/cm^2) Output Power (dBm) Gain of Antenna (dBi) MPE distance (cm) 902.60 0.60 +11.30 0 1.337 915.00 0.61 +9.30 0 1.053 927.40 0.62 +11.15 0 1.285 Conclusion For mobile or fixed location transmitters, the minimum separation distance is 20cm, even if calculations indicate that the MPE distance would be less. Therefore, the minimum safe distance has to be inserted in the EUT’s User Manual.
