Installation and Operation Guide Installation & Operation Guide MDS 05-3301A01, Rev. C JULY 2004 900 MHz Spread Spectrum Data Transceivers Microwave Data Systems Inc. MDS 9810 QUICK START GUIDE Below are the basic steps for installing the transceiver. Detailed instructions are given in “INSTALLA- TION” on Page 14 of this guide. 1. Install and connect the antenna system to the radio •Use good quality, low-loss coaxial cable. Keep the feedline as short as possible. •Preset directional antennas in the direction of desired transmission. 2. Connect the data equipment to the radio’s INTERFACE connector •Connection to the radio must be made with a DB-25 Male connector. Connections for typical systems are shown below. •Connect only the required pins. Do not use a straight-through RS-232 cable with all pins wired. •Verify the data equipment is configured as DTE. (By default, the radio is configured as DCE.) 3. Apply DC power to the radio •Observe proper polarity. The red wire is the positive lead; the black is negative. 4. Set the radio’s basic configuration with a Hand-Held Terminal (HHT) • Set the baud rate/data interface parameters as follows. Use the BAUD xxxxx abc command, where xxxxx equals the data speed and abc equals the communication parameters as follows: a = Data bits (7 or 8) b = Parity (N for None, O for Odd, E for Even c = Stop bits (1 or 2) (Example: BAUD 9600 8N1 ) NOTE: 7N1, 8E2 and 8O2 are invalid parameters and are not supported by the transceiver. 5. Verify proper operation by observing the LED display •Refer to Table 4 on Page 26 for a description of the status LEDs. •Refine directional antenna headings for best received signal strength using the RSSI command.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 July 26, 2004 RE: FCC ID: E5MDS-9810_ATCB001525 Attention: Juan Martinez I have a few comments on this Application. Please note that further comments may arise in response to answers provided to the questions below. 1. FYI - Please note that the MPE report states 0.020cm for d. This should be 0.020 m or 20cm. Please also note that the MPE report shows that antenna with greater gain than 10dBi require more than 20cm separation. Please address this issue. 2. Please note that the first table in the MPE report uses a frequency of 1500MHz. Please note that this device operates in the 902 to 928 MHz range – thus giving an r of 10cm.. Please provide an MPE report which addresses the frequency range of the device. 3. Please note that it does not appear that the manual addresses the minimum separation distance between the antenna and the user. Please address this issue in the manual and please be consistent with other documentation. 4. Please note that at the frequencies of concern, cardboard may not be the best or idea material for support of the antenna. Please justify and/or explain what measures were taken to verify that the cardboard box had no adverse affects on the readings for spurious emissions. Please note that a more appropriate material may be Styrofoam supports. 5. Please provide a hop table showing the pseudo random nature of the hop sequence. IC 6. Please note that the RSP100 form indicates that the power is a step function. This would also indicate that minimum and maximum power level existed. Please note that you have not provided a minimum power level for this device. Please explain, or alternately please provide the measured minimum power level for the device. Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the sender.

Page 1 of 1 RE: FCC ID: E5MDS-9810_ATCB001525 1. FYI - Please note that the MPE report states 0.020cm for d. This should be 0.020 m or 20cm. Please also note that the MPE report shows that antenna with greater gain than 10dBi require more than 20cm separation. Please address this issue. Response: The MPE report has been corrected. 2. Please note that the first table in the MPE report uses a frequency of 1500MHz. Please note that this device operates in the 902 to 928 MHz range – thus giving an r of 10cm.. Please provide an MPE report which addresses the frequency range of the device. Response: The extra table was just an example and has no meaning to what was tested. This example table was removed and a revised MPE has been uploaded. 3. Please note that it does not appear that the manual addresses the minimum separation distance between the antenna and the user. Please address this issue in the manual and please be consistent with other documentation. Response: The manual provided was the original manual used for similar past approved MDS9810. For this reason a portion of that manual was uploaded to the RF Exposure exhibit. This portion will show the minimum separation, which the MPE calculated to be 22cm. This portion of the manual has been uploaded to the Manual exhibit instead, for your review. 4. Please note that at the frequencies of concern, cardboard may not be the best or idea material for support of the antenna. Please justify and/or explain what measures were taken to verify that the cardboard box had no adverse affects on the readings for spurious emissions. Please note that a more appropriate material may be Styrofoam supports. Response: Justification was done by measuring the fundamental at 3 meters. The Calculated values yield a field strength of 130.7 dBuV/m @ 3 meters at 928 MHz. A measured value at 3 meters for 928 MHz yield a field strength of 128.4 dBuV/m. The difference is only 2.5 dB which could be cause by the Yagi not having a true 10dBi gain at the frequency, cable loss, and measurement uncertainty. But, it is still within the site’s +/- 4dB deviation. For future tests we will use Styrofoam. Calculated Frequency Power Gain EIRP EIRP (MHz) (dBm) (dBi) (dBm) (dBuV/m) 902 25.6 10.0 35.6 130.9 928 25.4 10.0 35.4 130.7 Measured @ 3 meters Frequency EIRP (MHz) (dBuV/m) 902 127.4 928 128.2 Page 2 of 2 5. Please provide a hop table showing the pseudo random nature of the hop sequence. Response: Hopping sequence has been uploaded. IC 6. Please note that the RSP100 form indicates that the power is a step function. This would also indicate that minimum and maximum power level existed. Please note that you have not provided a minimum power level for this device. Please explain, or alternately please provide the measured minimum power level for the device. Response: RSP-100 form has been revised with the minimum power level of the lowest setting. Regards, Juan Martinez Sr. EMC Engineer

Mr. Dennis Ward, Subject: Amendment of power to FCC and IC grants Applicant: Microwave Data Systems Inc. Model: MDS9810 FCC ID: E5MDS-9810 The following amendment is requested to be made to the grant: 1) Power change, on grants, from .363 to .955 Watts. Report and new data has been included to reflect change in power. MPE calculation, 731 form, and RSP-100 form have all been revised to reflect new power. 2) Client will like the following statement on the grant, if possible: “antenna(s) of lower gain and in the same family Yagi or Omni are type approved for use” Regards, Juan Martinez Sr. EMC Engineer
