FCC INTEGRATION INSTRUCTIONS

GENERAL

Some items which must be fulfilled in order to be compliant with general FCC rules.

LIST OF APPLICABLE FCC RULES

Following FCC rules are applicable to the HTRM1100 module and must be kept: FCC Part 15, Subpart C: §15.203, §15.205, §15.207, §15.215

SPECIFIC OPERATIONAL USE CONDITIONS

Keep the limitations on antennas given in section 6.56.5.

LIMITED MODULE PROCEDURES

As the HTRM1100 is not a “Limited module” the “Limited module procedures” are not applicable.

TRACE ANTENNA DESIGNS

Since it is not intended to use trace antennas with the HTRM1100, this item is not applicable.

RF EXPOSURE CONSIDERATIONS

SAR testing is not required for transmitters where a distance to the human body of less than 20 cm is not expected. Therefore the module and its antennas are not suitable for applications where the antenna is generally closer than 20cm to a human body.

ANTENNAS

In order not to break FCC rules only use antennas specified in Chapter 6.5.

FCC LABELLING

Figure 1: FCC Label of the Module
Figure 1 shows the FCC label which is permanently attached to the shielding tin of the module. Note: The final device must have a label on the outside that provides information about the integration of the module and the following information:

Above information must also be included in the final device manual.

INFORMATION ON TEST MODES AND ADDITIONAL TESTING REQUIREMENTS

FCC document “996369 D04 Module Integration Guide v02” give some suggestions for common technology types on how the host product manufacturer may operate their product during investigative measurements. The HTRM1100 is not operating in these common technology types and these investigative measurements are not applicable.

PART 15 SUBPART B DISCLAIMER

The HTRM1100 module is approved for FCC Part 15 Subpart C only. The manufacturer of the host product is responsible for compliance with all other FCC regulations that apply to the host and are not covered by the HTRM1100 certification. In particular, this applies to FCC Part 15 Subpart B.

IMPORTANT MOUNTING INFORMATION

INSTALLATION ENVIRONMENT

• This freaquent reader module is considered a component which will be installed into a final equipment.
• Install this freaquent reader module only in an environment whose compliance with the conditions, specified in 7 HTRM1100 Product Specification in, is assured.
• The environment must not contain corrosive, flammable or explosive materials or be subject to rapid changes in temperature, to direct vibration or shock.

NOTIFICATION

• freaquent ’s RFID readers communicate with data carriers (RFID inlets, labels and tags) using a 134.2 KHz carrier frequency (LF band). Some industrial machines and electronic devices can generate unwanted noise which may degrade the communication. Make sure that other equipment is properly installed, grounded and at a reasonable distance from the reader and/or the reader antennas.
• The wireless communication of the reader can be degraded by high-voltage and high-current lines and other sources of strong electromagnetic fields. Installation in such locations should be avoided.

INSTALLATION

The module must be mounted into a cabinet or housing. The enclosure must be at least IP22 rated when used indoors and IP44 rated when the unit is intended to be operated outdoors. If screwing is necessary in order to fix the module 4 spacers of thread size M3mm (UNC 4-40 or 6-32) must be used. Use spacer bolts of minimum length 7mm (9/32 in) for mounting. If screwing leads to a conducting connection to a metal mounting plate, the plate must be grounded to potential earth.

POWER SUPPLY

The freaquent reader module works with supplies from 12V to 18V DC. The module needs to be grounded. Only use supplies in accordance with 7 HTRM1100 Product Specification. The power rating of the supply must be P=25W at the minimum. Only use FCC certified supplies. Note: The communication range of the system depends as well on the supply voltage. Maximum reading distance is achieved with the maximum supply voltage of 18 VDC.
Connect the supply a shown in Figure 3. If V- of the used supply is electrically identical with the potential earth, the connection of potential earth can be omitted. The terminal block fits wires from 0.5 mm² – 3.3 mm² (20 AWG – 12 AWG).

ANTENNAS

In order to comply with part 15 of the FCC and the CE regulations only magnetic loops with an enclosed area of not more than 0.375 sqm (A<= 0.375m²) and not less than 0.004 sqm (A>= 0.004m²) must be used and connected to the module. Only antennas which are manufactured or certified by freaquent must be used.

The reader module HTRM1100 disposes automatic tuning of antennas. An antenna for the HTRM1100 is a simple magnetic loop within a certain inductance. The antenna cable inductance must be added to the loop inductance and the sum of the inductances must be in the range given in: 7 HTRM1100 Product Specification. If the sum of inductance is within this range the module automatically tunes the output circuitry to series resonance with a resonance frequency close to the working frequency.

Connect the loop to the outer clamps (1 and 3) of the antenna terminal. The middle clamp (2) of the antenna connector is foreseen to connect the cable shield wire to ground. For the case the cable shows no shield wire, clamp 2 is not in use. Please refer to Figure 4. The antenna cable wire cross section must be in the range 0.75 mm² – 3.3 mm² (18AWG-12AWG).
