COMPACT 900 MHZ RF

Microhard Systems Inc. CompactRF TM Operational Description CompactRF TM Operational Description1 1.0 Operational Description The CompactRF TM is a high-performance embedded spread spectrum data transceiver. Users communicate with this module via an asynchronous RS-232 interface. All data that users send to the module is buffered in banks of SRAM memory, packetized with the appropriate header information, and sent over the air at a fixed bit rate. The microprocessor inside the module precisely controls the bit-width, packet size, and hopping algorithm, to ensure that the RF occupied bandwidth and channel dwell-times remain constant. Users have no ability to modify the occupied bandwidth of the transmitted data. Users power the module from a 5 - 5.5V source. This is linearly regulated down to 4.5V for all radio circuitry. This ensures that any changes in input voltage will not have any effect on the radiated power, which is limited to 1W. The CompactRF TM modem can be configured for a wide range of applications. The module is designed such that all communication is through one serial port (Pins 21 to 28 on the module). This port has two functions: 1. It provides the asynchronous interface with the host equipment for data that is sent/received on the RF channel. When operating in this fashion, the module is said to be in data mode. 2. It is also used for configuring and programming the module. When operating in this fashion, the module is said to be in command mode. The functionality of any particular CompactRF TM can be configured as follows: nMaster Point-to-Point: The modem is configured to communicate with a single Slave, either directly, or through one or more Repeaters. nMaster Point-to-Multipoint: The modem is configured to communicate with one or more Slaves and/or Repeaters. nSlave: The modem is configured to communicate with one Master either directly or through one or more Repeaters.. nRepeater: The modem is configured to pass information from either a Master or another Repeater onto subsequent Repeaters and/or Slaves and vice versa. The Repeater also acts as a Slave in the sense that, like a Slave, it passes information to/from its serial port. The CompactRF is a frequency hopping transceiver, meaning that it “hops” to a new frequency after a predetermined time interval. This time interval is a fixed time set by the user, and can range from 14ms to 180ms. The CompactRF hops according to a pseudorandom pattern of 50 different channels. There are 64 available channels with spacing of 400 kHz starting at 902.4 MHz and going up to 927.6 MHz. The RF connector on the module is an End Launch Reverse-Thread SMA Bulkhead Jack Receptacle. The manufacturer's part no. is: Johnson 142-5701-811 Microhard Systems Inc.

Description of Unique Connector FCC regulation (Part 15.203) stipulates that wireless devices with removable antennas require a non-standard antenna connection to the hand-held device. To meet this requirement, we are using a Johnson Components reverse threads (left hand). The RF connector on the module is an End Launch Reverse-Thread SMA Bulkhead Jack Receptacle.

RF Exposure Calculations: The following information provides the minimum separation distance for each of the antennas provided with the COMPACTRF- 900 module, as calculated from FCC OET 65 Appendix B, Table 1B Guidelines for General Population/Uncontrolled Exposure. This calculation is based on the highest EIRP possible from the system, considering maximum power and antenna gain. The formula used was: S = (Po*G)/(4*pi*r^2) Where S = 0.62 mW/cm^2 for 928 MHz (from F/1500) Where Po = 100 mW for Yagi antennas (max. power set at factory) Where Po = 1.0 Watt for Omni antennas (max. power user configurable) For: 14 dB Yagi Antenna . . . . . r = 18 cm 2.5dB Omni Antenna . . . . . r = 15 cm 6 dB Omni Antenna . . . . . r = 23 cm The following statement will be presented in the COMPACTRF-900 User Manual: WARNING In order to comply with the FCC/IC adopted RF exposure requirements, this transmitter system will be installed by the manufacturer's resaler professional. Installation of all antennas must be performed in a manner that will provide at least 23 cm clearance from the front radiating apperature, to any user or member of the public. .

The Equipment Under Test (EUT) was the Model: CompactRF-900 Wireless Modem Transceiver /OEM Module. Radio-Noise Emissions tests were performed according to FCC Public Notice 54797, titled “Guidance on Measurement for Direct Sequence SST”. The measuring equipment conforms to ANSI C63.2 Specifications for Electromagnetic Noise and Field Strength Instrumentation. Testing was performed at National Certification Laboratory in Ellicott City, MD. Site description and site attenuation data have been placed on file with the FCC’s sampling and Measurements Branch. FCC acceptance was granted on May 26, 1993. 1.1 Summary: The Microhard Systems, Inc., Model: CompactRF-900 Wireless Modem Transceiver /OEM Module complies with the FCC limits (15.247) for a Frequency Hopping SST. FCC ID #: NS900P3 3 2.0 Description of Equipment Under Test (EUT): The EUT features: 3.0 Test Program: This report contains measurement charts and data as evidence for the following tests performed: 1.(15.247b) Peak RF output power. 2.
