MKRS556-EP NamePlate Information The information below is excerpted from the TEST REPORT FOR TYPE ACCEPTANCE of TRANSCEIVER MODEL S556-EP FCC ID MKRS556-EP that was submitted to the FCC on December 29, 2000. The Submission Confirmation Number is EA99662. The nameplate is affixed permanently to the upper left corner of the rear panel of the MKRS556-EP. The nameplate size is 2.5” x 2.0”

The information below is excerpted from the TEST REPORT FOR TYPE ACCEPTANCE of TRANSCEIVER MODEL S556-EP FCC ID MKRS556-EP that was submitted to the FCC on December 29, 2000. The Submission Confirmation Number is EA99662. 1. Circuit Diagrams and Descriptions The top-level circuit diagram for the entire system is shown below in Figure 1. The Transmitter section is shown in Figure 2. Figure 1. MKRS556-EP Top Level Schematic Diagram Figure 2. MKRS556-EP Transmitter Section Schematic Diagram A. Description of frequency determining circuitry The RF frequency is generated using a phase locked loop (PLL) circuit. The licensed frequency data is burned into flash memory. At startup the microprocessor sends the PLL integrated circuit (National Semiconductor’s LMX2325TM) the serial information for the set frequency. The PLL IC uses a 20 MHz crystal oscillator as a reference frequency. The PLL IC generates a voltage for the voltage-controlled oscillator (VCO). The VCO generates the RF signal, which is fed back to the PLL IC. The PLL IC divides this signal down, and compares it to the 20 MHz reference. In the closed control loop, the PLL IC’s output voltage is adjusted to precisely maintain the set frequency. B. Description of circuitry used for spurious, modulation and power limiting The MKRS556-EP RF output is on/off modulated. This modulation is accomplished using the analog gain control pin of an RF amplifier (RF Micro Devices RF2126). This gain control is set with a discrete signal from the field programmable gate array (FPGA). An RC filter on this line provides transmission bandwidth limiting. A 3 section, low-pass filter located at the output of the final RF amplifier limits harmonic emissions. The RF output power level is set using an analog control voltage in the amplification stage prior to the final amplifier. During final assembly, a digital potentiometer is adjusted to provide a desired output power at the RF output port. The digital potentiometer value that corresponds to the desired output power is then burned into flash memory. C. Description of Modulation technique and circuitry The MKRS556-EP Transceiver uses an RF on/off modulation scheme. The RF signal powers the ID tag in the field, and then communicates with the tag by briefly turning off the RF power at the proper time. The waveform timing and duty cycle depend on the transmitted symbol. There are 3 transmitter waveforms. In the alternative, the transceiver sends a clock, a logic “0”, or a logic “1”. Figure 1 shows the timing for each of these waveforms. The modulation either has the RF at full strength in the “on” state or attenuated by at least 20 dB in the off state. Any time the scanner is normally operating, the RF signal is continuously being modulated. The system is operating CW (un-modulated) only when the transceiver is instructed to operate as such, via operator command. The sequence of clock, logic “0” and logic “1” information being transmitted depends on the commands issued by the processor and by the tag responses. The modulation of the signal is controlled with a digital pulse sequence from the FPGA. This signal is RC filtered to limit the transmission bandwidth, and then is sent to the analog gain control of an RF amplifier. The RF amplifier attenuates the RF signal by a minimum of 20 dB when in the “off” state.

February 13, 2001 FCC Application Processing Branch Regarding: FCC ID MKRS556-EP Form 731 Confirmation Number EA99662 Correspondence Reference Number 18069 1. The Necessary Bandwidth as defined in CFR 47 part 2.202 (c) (4) is 714 kHz. This value was submitted in the Test Data Report (section 4). The modulation was expressed incompletely as K1D, the more accurate expression, in accordance with CFR 47 parts 2.201 and 2.202 (b) would be 714KK1D. 2. The MPE in the uncontrolled case is 1 mw/cm 2 (OET Bulletin 65 Appendix A). The gain of the antenna that is sold with this system is 8 dBi. Rewriting equation (3) from OET Bulletin 65 Section 2, R = ½ * sqrt ((P*G)/(pi*S)). P = 5000 mW G = 6.3 numeric (8dBi) S = 1 mW/ cm 2 Solving, the range at which the field intensity falls below the MPE is 50.1 cm, or 19.7 inches. We added a 10% “fudge factor” in our expression of 22 inches as the uncontrolled range in our User’s Manual. Regards, Gary Bann

February 19, 2001 FCC Application Processing Branch Regarding: FCC ID MKRS556-EP Form 731 Confirmation Number EA99662 Correspondence Reference Number 18069 On February 13, I sent you a quick, “off-the-top-of-my-head” calculation showing how we arrived at the MPE figure for the MKRS556-EP device. Upon reviewing my data, I find that I only provided the calculation for the uncontrolled case, and slightly overstated the gain of our antenna. Here are the corrected calculations. 1. The MPE in the uncontrolled case is 1 mw/cm 2 (OET Bulletin 65 Appendix A). The gain of the antenna that is sold with this system is 7.8 dBi. Rewriting equation (3) from OET Bulletin 65 Section 2, R = ½ * sqrt ((P*G)/(pi*S)). P = 5000 mW G = 6.0 numeric (7.8dBi) S = 1 mW/ cm 2 Solving, the range at which the field intensity falls below the MPE is 48.8 cm, or 19.2 inches. 2. The MPE in the controlled case is 5 mw/cm 2 (OET Bulletin 65 Appendix A). The equivalent calculation in this case with S = 5 mw/cm 2 finds R = 21.9 cm, or 8.6 inches. 3. I note that the manual states a range in inches of 8.5” instead of 8.6”. This is being corrected. Regards, Gary Bann SCS Corporation 858-485-9196 x 109 [email protected]

February 27, 2001 FCC Application Processing Branch Regarding: FCC ID MKRS556-EP Form 731 Confirmation Number EA99662 Correspondence Reference Number 18221 Responding in turn to each of your questions: 1) This device operates with 6 antennas. It is noted that no more than one antenna transmits at any given time. Each antenna has two cables. The operational description did not elaborate on this. Please elaborate on the function of the two cables going to each antenna. Each antenna referred to is actually two identical helical antennas contained in one housing. In normal operation one of the pair is used as a transmit antenna, the other as a receive antenna. Because the system is transmitting and receiving at the same time, sufficient isolation between the transmitter and receiver is achieved by using separate antennas. The MKRS556-EP provides the capability to swap the pair around, so that the original transmit antenna in the pair is now the receive antenna and vice versa. To answer your question directly, each cable is an RF cable, capable of either being used for transmission or reception. 2) In this application, MPE was for the Occupational/Controlled Environment limit. A previous application (EA99257) for a similar device used the General Population/Uncontrolled Environment limit. It is suggested that you submit new exhibits for this application using the General Population/Uncontrolled Environment limit and using the similar application as a model. This application does not have any information indicating that the Occupational/Controlled Environment limit would be applicable for MPE. I am resubmitting the MPE calculations you requested for the General Population /Uncontrolled case only. Further, changes to the Operation Manual similar to those of the EA99257 application are being resubmitted. The MPE in the uncontrolled/general population case is 1 mw/cm 2 (OET Bulletin 65 Appendix A). The gain of the antenna that is sold with this system is 7.8 dBi. Rewriting equation (3) from OET Bulletin 65 Section 2, R = ½ * sqrt ((P*G)/(pi*S)). P = 5000 mW G = 6.0 numeric (7.8dBi) S = 1 mW/ cm 2 Solving, the range at which the field intensity falls below the MPE is 48.9 cm, or 19.2 inches. We rounded to 20 inches in our manual.

12 Placing the Antenna Antenna placement is critical to ensuring that information is transmitted to and from tags accurately. Observe the following guidelines when plac- ing the antenna: Locate the antenna away from metal objects, microwave ovens, and other devices that may induce radio frequency interference. In addition, make sure there are no metallic surfaces between, or in relative proximity to, the scanner and tag. For additional placement considerations, refer to “RF Communications” on page 23. When reading, the antenna should be placed no more than 60 inches from the objects bearing tags. When writing, the antenna should be no more than 20 inches from objects bearing tags Caution: to meet FCC RF Exposure compliance, operator(s) should not be closer than 20 inches to a transmitting antenna. See RF Exposure precautions on page 41. The front of the antenna must be free of obstructions. Otherwise, information may not be written to and read from tags accurately. IAntennas must be labelled indicating minimum separation distance per FCC RF Exposure requirements (page 41). If the information on the label is not clearly visible, a sign with the same information must be posted within 36” of the antenna. (see last page of this manual) ITags must reside within the scan field for at least 3 milliseconds for information to be retrieved from them. 556-EP Manual.P653/7/2001, 2:02 PM12 RF Exposure "Caution" Label Purpose: To meet FCC requirements with regard to RF Exposure, for applications where an individual antenna is used in conjunction with an SCS S556-EP InstaScan® scanner, the antenna must have affixed to it, a label indicating the minimum separation distance required to meet FCC RF Exposure compliance.
