The DM1800 family is designed for adding embedded wireless connectivity to a wide range of monitoring and control systems. The DM1800-916MB is equipped with a serial I/O port to interface to a host microcontroller. The module also includes an analog input, a logic input, and a logic output for local monitoring and control. Radio communications range in an “open field” environment is typi - cally 200 meters/hop. The DM1800-916MB combines RFM’s very low current ASH radio technol - ogy with low power microcontroller technology to achieve long battery life. This module is compatible with RFM’s miniMESH TM network protocol, which provides add-on “plug-and-play” multicast mesh network routing. The DM1800-916MB is certified for operation under FCC 15.249 regulations. • Base Station with Host Serial Interface • Compatible with RFM miniMESH TM Network Protocol • 3 V, Very Low Current Operation • Ready-to-Use OEM Module 2 Theory of Operation The major components of the DM1800-916MB include an RFM TR1000 ASH transceiver and a Microchip PIC16F688 microcontroller.

FCC ID: TE6DM1800 TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of TIMCO ENGINEERING, INC. 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 74.3°F 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 ANSI STANDARD C63.4-2003 10.1.7 MEASUREMENT PROCEDURES: The UUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The UUT was placed in the center of the table (1.5m side). The table used for radiated measurements is capable of continuous rotation. When an emission was found, the table was rotated to produce the ma…
