LC6-4053Industrial Reader

MICRON COMMUNICATIONS, INC. 3176 South Denver Way; Boise, Idaho 83707-0006 MicroBadge 4053 Users Manual Users Manual MicroBadge 4053 NOTE: - This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of the equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. MICROBADGE 4053 USERS MANUAL 1 11 1 Table of Content SECTION 1 MicroBadge 4053 Reader Description1 SECTION 2 Installation Instructions2 SECTION 3 Operating Limitations3 SECTION 4 Maintenance4 MicroBadge 4053 Reader Description The MicroBadge 4053 RFID reader is a self-contained low frequency reader for powering and interrogating passive RFID transponders. The reader is configured to interface with other electronic devices via an RS-232 or RS-485 connection. The 4053 reader emits a low frequency magnetic field, which will provide enough energy to power a transponder within the read range of the transponder. The transponder will send a unique identification, which the reader detects. If the identification code is valid and the internal error detection determines that there are no errors in the data received, an audible tone is emitted, the red LED on the front of the reader turns to green, and the code is sent to the RS232 or RS484 port of the reader. SectionSection 1 3 33 3 Installation Instructions The reader should be mounted near the location that is desired to be monitored. Before final installation of the reader, test the system with tags at range and orientation typical of system operation. Typically, the read range for a credit card size transponder is approximately 8 inches, and an 18mm button transponder has a read range of 5 inches. Caution should be taken that the reader is not mounted within 12 inches of metallic objects, because of possible performance degradation of the system. Once a suitable location is determined, position the reader to allow the transponder to be presented nearly parallel to the face of the reader. This allows for the greatest read range for the entire system. After the reader is mounted, the 12 VDC (nominally) power transformer should be plugged into a 110 volt, 50 – 60 Hz socket, and the power plug from transformer should be plugged into the reader power jack. The LED indicator on the front of the reader should be glowing with a RED color. Next, plug an RS232 cable with a nine–pin connector into the RS232 port of the reader, and connect the other end of the cable into the serial port of a computer. To test the functionality of the reader, start up a terminal program in the computer. (PROCOM or Windows terminal program will work fine.) Set the communications parameters to 19,2000 baud, no parity, eight data bits, and one stop bit. Make certain that the port selected in the terminal port corresponds to the port that the RS232 cable is connected. Next, present a transponder to the reader at approximately 4 inches and parallel to the face of the reader. An audible “beep” should be heard, and the LED should alternately flash RED and GREEN. Moreover, you should see a string of 18 digits displayed on the computer monitor. These digits correspond to the identification code stored in the transponder. If an audible “beep” is head, but the computer does not display the 18 digits on the monitor, verify that the proper port is selected, and that the proper communications parameters are set. Section 2 4 44 4 If an audible “beep” is not heard, verify that the LED is glowing RED, which indicates that power is being supplied to the reader. Try another transponder, and bring it closer to the reader antenna. If this fails to produce a sound, disconnect the unit from the computer and from power and call the factory. 5 55 5 Operating Limitations Storage Temperature-5590Degrees C Operating Temperature-4070Degrees C Operating Frequency123127 KHz Read Range 050cm Power Consumption1.5Watts Power Supply Voltage9.015.0 VDC Section 3 6 66 6 Maintenance There are no user repairable components within the reader, and any maintenance performed on the reader should be performed only by factory trained personnel.

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 connected. - Consult the dealer or an experienced radio/TV technician for help.

FCC ID: LC6-4053 ENGINEERING STATEMENT For Certification of Micron Communications, Inc. Industrial Reader FCC ID: LC6-4053 Model No. 4053 I am an Electromagnetic Compatibility test engineer with TUV Product Service, Boulder, Colorado. My education and experience are a matter of record with the Federal Communications Commission. TUV Product Service Corporation has been authorized by Micron Communications, Inc. , 3176 South Denver Way, Boise, Idaho 83707-006, to make FCC Part 15 Certification measurements on the Industrial Reader. These tests were made by me or under my supervision at our Pinewood Springs Laboratory which is registered with the FCC under Paragraph 15 of the FCC Rules. Test data required by the FCC for FCC Part 15 Certification is included in this report. It is submitted that the above equipment meets FCC requirements and FCC Part 15 Certification is hereby requested. ________________________ Shawn Singh Engineer TUV Product Service Dated: 18 November 1998

January 05, 1999 FCC Laboratory 7435 Oakland Mills Road Columbia, MD 21046 Re. FCC ID: LC6-4053, Form 731 Confirmation Number EA92367 Dear Certification Officer, TUV Product Service submitted a 15.209 electronic application on behalf of Micron Communications, Inc. on 11/18/98. The equipment passed FCC Class A emissions testing, however, per 15.207 requirements the equipment did not pass Class B requirements for conducted emissions. The equipment was retested with a new power supply and passed FCC Class B conducted emissions as well as radiated emissions with a Phihong PSA-30U-150 AC adapter with a shielded power cord. They will market their equipment with Phihong AC adapter in place of Condor D7-10-01 transformer which was originally tested. A ferrite manufactured by Fair-rite, part# 0443164251, was also removed from the 7.5 ft antenna cable on the tag reader side. We are submitting a new test report and revised user manual and photos which reflect the retested data. Please feel free to contact me for any additional information. Sincerely, Shawn Singh EMC Engineer TUV Product Service
