Number: EA101242 Page 1 Enclosed are the replies to your questions some of the answers are based on a conversation of the questions between yourself and Adcon. 1. 1) Verify the requested frequency range should be 902.8-910.15 MHz. The frequency range should 902 – 911 MHz not 902-928. 2. Confidential letter. I have uploaded the confidentiality letter. 3. Submit appropriate fees. I have submitted the payment for this job. The remittance number is 150542 and the authorization number 123285. 4. Indicate compliance with the RF safety requirements. The RF exposure statement is included in the revised user’s manual, which has been uploaded to you. Page number 5 of the revised users manual. 5. Why was the device tested without the enclosure shown in the external photos? The corrected test setup photograph is included as page 5 of this letter and has been uploaded. The one originally sent with this job was the wrong photo. 6. Provide a bandwidth plots on a low, middle and high channel. Bandwidth plots on low middle and high channels are included as pages 7,8, and 9. 7. External photo of the top of the device. The top photograph is included as page 4 and has been uploaded to you. 8. The device has an RS232 port for connecting to a computer. File a composite application for the peripheral portion. Or if it DOC approved, provide the DOC certificate and correct the label to include the DOC label requirements. The D900SS-20-A is an evaluation tool for engineers and is not going to be used in the home or available for sale to the general public for home use, and as such falls under a Class A peripheral. The test report has been updated to reflect this and uploaded to you included in this report as page 6. 9. The manual indicates the use of other antennas that were not tested. Please correct the manual accordingly. This is addressed partially in item 8 above and in revision 0.6 of the users manual has been uploaded to you. See page 6 of this report. 10. How does the device comply with Section 15.203? The antenna is permanently attached and is addressed on page 3 of the test report. 11. The transmitter cannot coordinate its hopping sequence with the hopping sequence of other transmitters, or vice versa, for the purpose of avoiding the simultaneous occupancy of individual hopping frequencies Timco Engineering Inc. Adcon Telemetry Inc. 849 NW State Road 45 FCC ID: MQXD900SS-20-A Newberry FL 32669 Corresp. Number : 20075 731Conf. Number: EA101242 Page 2 by multiple transmitters. Provide a description on how the device complies with this rule. Once the radios have been configured and completed the “acquisition procedure”, the radios in the network operate completely independently of any other radios in the local area. Eight different hopping tables are available for each network, and this provides an additional method to minimize collisions between networks. 12. The system shall hop to channel frequencies that are selected at the system hopping rate from a pseudorandomly ordered list of hopping frequencies. Indicate how the pseudorandom hopping sequence is derived. The 8 pseudorandom hopping tables are burned into the EEPROM memory, and do not change. All 8 tables have the following characteristics: they use each channel only once per 50 hops, and they move randomly both in direction and in number of channels hopped. They were derived with the following procedure: The first three tables were created with an algorithm “maximal-length pseudo- random linear feedback shift register (LFSR)” based on maximum lengths of 6,7,8 bits, with rejection of frequencies already used. The other tables (tables 4-8) were created with an algorithm based on the RANDOM () function, with rejection of frequencies already used. 13. Each frequency must be used equally on the average by each transmitter. Except for voice systems, each new transmission must start at a different point in the sequence so that on average the full sequence is used. Therefore, Describe where the next transmission starts when all frequencies are not used for a previous message. This is required because some transmissions may need only a few frequency hops to be completed. i.e. If the transmission started on the same frequency each time, this frequency would be used more than the others if many short transmissions were sent. The next transmission starts with the next channel in the hopping table sequence. For example, if a short transmission starts with the first channel in the hopping table and needs only 8 hops to complete the transmission, the next transmission will start with the ninth channel in the hopping table sequence. 14. Section 15.247(a) 1 indicates that the system receivers shall have input bandwidths that match the hopping channel bandwidths of their corresponding transmitters and shall shift frequencies in synchronization with the transmitted signals. Please explain how the device complies with this rule when a packet is repeated or when multiple packets are sent. What is the receiver input bandwidth? How does the receiver shift frequencies and determine which frequency to shift to in order to synchronize with this transmitter? The receiver uses a VCO to rapidly shift frequencies in synchronization with the transmitted signals, based on the hopping table that was chosen during the acquisition procedure.

Number: EA101242 Page 3 When a packet is repeated, it is transmitted on the next hopping channel, which is a different frequency. The receiver input bandwidth is limited by the filters on the receiver, which have a pass band of +/- 50kHz at 3dB. The adjacent channel rejection is 20dB. The receiver shifts frequencies with the following procedure: After changing to a new hop…

The UUT was transmit- ting a test signal during the testing. 15.247(a)(1) CARRIER FREQUENCY SEPARATION & NUMBER OF CHANNELS: A near field probe was used to sense the signal of the UUT. The UUT was made to hop its full range. The spectrum analyzer was set to view the frequency range from 902 to 910MHz and placed in the memory mode. A plot (Exhibit #9) was then made of the display showing the number of channels, 50 and the separation of the channels, 152 kHz. 15.247(a)(1)(i) CARRIER FREQUENCY DWELL TIME: A near field probe was used to sense the signal of the UUT. The UUT was made to hop its full range. The spectrum analyzer was set to view the frequency range from 902 to 928 MHz and the center of the HOPPING RANGE was centered on the Spectrum Analyzer. The SPAN was then set to ZERO(0) and the SWEEP TIME was set to 20 seconds. Then by analyzing the plot of the total ON TIME of the UUT during the 20 seconds it was determined the dwell time on any frequency was less than 0.4 seconds, 23.70 mseconds. See exhibit #11. 15.247(b)(2) POWER OUTPUT: The RF power output was measured at the antenna feed point by removing the permanent antenna and connecting the UUT to a peak power meter, HP Model No. 8900C. 15.247(c) ANTENNA CONDUCTED EMISSIONS: The RBW=100kHz, VBW =1.0MHz up to 1000MHz and RBW=1.0MHz & VBW=3.0MHz above 1.0GHz. The spectrum was scanned from 30MHz to the 10th Harmonic of the fundamental. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. 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 300 kHz up to 1.0GHz and 1.0MHz with a video BW of 3.0MHz above 1.0 GHz. The ambient temperature of the UUT was 72.2°F with a humidity of 54.2%. The hopping was stopped at the low end, middle and high end of the band in order to test the radiated emis- sions. POWER LINE CONDUCTED INTERFERENCE: The procedure used was ANSI STAN- DARD C63.4-1992 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10kHz with an appro- priate sweep speed. The ambient temperature of the UUT was 74°F with a humidity of 54%. APPLICANT: ADCON TELEMETRY, INC.
