QNT-PT108-00010012442MHz Wireless Modem

- iii - FCC Declaration of Conformity This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: i) this device may not cause harmful interference, and ii) this device must accept any interference received including interference that may cause undesired operation. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is needed. • Consult the dealer or an experienced radio/TV technician for help. RS-232 DB9 shielded cable with ferrite must be used with this unit to ensure compliance with the Class B FCC limits. CAUTION: The model number PT-108U has maximum transmitted output power of 0.5 Watt. It is recommended that the transmit antenna be kept at least 20 cm away from nearby persons to satisfy FCC RF exposure requirements. The antenna and transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 7 3.1 Setting up Connections PT-108U modems are supposed to work properly when they are delivered from REnex. Hence, the only thing users need to do is to make the appropriate application interface connections and power up. The master and slave(s) shall communicate properly. The pin definitions of the application interface are listed in Table 2. Users may connect the RS-232 pins to their equipment according to their practical situations. For any enquiry, please contact REnex for further information. 3.2 Checking the Link After finishing the physical connection setup mentioned above, PT-108U should be ready. If the performance of the communication links is not satisfied or any linking problem is found, the following steps may help you locate the problem. 1. Install DB-9 connectors to the PT-108U modems as described in Section 2.4. 2. Connect each modem to a serial port of a PC. 3. Start a terminal program such as Hyper Terminal (http://www.hilgraeve.com , it may be found in Microsoft Windows OS) for each serial port. Make sure the baud rate and data format settings agree with those of PT-108U. 4. Type characters to the master’s terminal should appear at that of the slave’s and vice versa. 5. The TX LED should flash during transmitting data to the RF link. 6. The RX LED should flash during receiving data from the RF link. 7. Adjust the modem separations and the antenna direction to locate positions with the best performance. 3. Setup PT-108U NOTE 2: PT-108U is highly sensitive to obstacles in its communication path. Make sure the communicating modems are in line-of-sight. Otherwise, the performance would drop significantly. NOTE 3: Antenna height is a critical factor. Try to put the antenna to a position as high as possible.

It is applicable for both 15.107 and 15.207 and tested with a typical AC to DC adaptor. 11) The MPE compliance estimation is attached for your review. Please let me if you need other information. Hope this application can be completed by this week as the client call me every day. Thank you. -----Original Message----- From: Mike Kuo [mailto:[email protected]] Sent: Thursday, November 28, 2002 9:14 AM Subject: RE: Renex Technology Limited, FCC ID:QNT-PT108-0001001, AN02T2423 and AN02T2421 Hi Tommy: Question #9: There is no request for confidentiality letter in the attachments. Please provide it. Question #10: Please provide AC line conducted emission test data per 15.107 / 15/207 requirement. Due to nature of the design of this device, please use a typical AC/DC power source to perform the tests. Question #11: MPE compliance can be addressed through estimation ( calculation ). Please provide it.

For the MPE evaluation, refer to Page 19 of Supplement C (Edition 01-01). Transmitters using indoor antennas that operate at 20 cm or more from nearby persons and operating at 4W EIRP (2.4 W ERP) or less at 2450MHz, generally are not expected to exceed MPE limits when nearby persons are 20 cm or more from most antennas. Please let me know what information that I need to provide to you or just an calculation of EIRP is sufficient. Looking forward to hearing from you. Thanks a lot!! Tommy. -----Original Message----- Sent: Wednesday, November 27, 2002 12:26 PM To: 'Mike Kuo' Subject: RE: Renex Technology Limited, FCC ID:QNT-PT108-0001001, AN02T2423 Dear Mike, 1) The spectrum plots are submitted separately and attached in the application of AN02T2421. 2) Two application fee is OK. 3) No, we will discuss with client and amend the user manual. In fact, this is a OEM product, it will be sold to other manufacturer and it needs to apply again after installation. 4) Sorry to missed in the file of "FCC information". Please refer to page ii of the user manual for 15.21. 5) Thanks for your advice, we will ask the client to add the statement. 6) Could you send me the sample or guideline to prepare the MPE evaluation?? 7) The letter is attached for your reference. If you need other information, please feel free to contact me. And have a nice "Thanks Giving Day". Thanks and best regards, Tommy. -----Original Message----- From: Mike Kuo [mailto:[email protected]] Sent: Wednesday, November 27, 2002 11:36 AM Subject: FW: Renex Technology Limited, FCC ID:QNT-PT108-0001001, AN02T2423 -----Original Message----- From: CERTADM Sent: Tuesday, November 26, 2002 7:35 PM To: '[email protected]' Subject: Renex Technology Limited, FCC ID:QNT-PT108-0001001, AN02T2423 Notice_content ------------- Question #1:Please provide 15.247 portion of test data.
