INTEGRATION INSTRUCTIONS
3.1 GENERAL
TWN4 MultiTech M may be installed into any host device, as long as it is
operated under the operational conditions stated in the product user manual
and other technical documents (e.g. data sheet). The product is equipped with
two integrated RFID antennas. Thus, no antenna installation is required.
3.2 LIST OF APPLICABLE RULES
Refer to the approval certificates, grants and declarations of conformity
issued for TWN4 MultiTech M, and to the following rules applicable to TWN4
MultiTech M:
- 47 CFR 15.207
- 47 CFR 15.209
- 47 CFR 15.225
- RSS-Gen
- RSS-102
- RSS-210
3.3 SPECIFIC OPERATIONAL USE CONDITIONS
There are no specific operational use conditions for TWN4 MultiTech M other
than the conditions mentioned in the product user manual and data sheet. The
host manufacturer and integrator must ensure that these use conditions comply
with the use conditions of the host device. In addition, these use conditions
must be stated in the user manual of the host device.
3.4 LIMITED MODULE PROCEDURES
Refer to the grant of equipment authorization or approval certificate issued
for TWN4 MultiTech M for more information.
3.5 TRACE ANTENNA DESIGN
n/a
3.6 RF EXPOSURE CONSIDERATIONS
The antennas of TWN4 MultiTech M must be installed to meet the applicable RF
exposure compliance requirements and any additional testing and authorization
process as required.
Refer to Chapter “Safety information” for detailed information about the radio
frequency exposure conditions applicable to the product. These RF exposure
conditions must be stated in the end-product manual(s) of the host device
manufacturer.
3.7 ANTENNAS
TWN4 MultiTech M is equipped with the following antennas: 
Integrated RFID LF antenna (125 kHz)
Dimensions: 29.00 x 32.00 mm / 1.14 x 1.26 inch
Number of turns: 164
Integrated RFID HF antenna (13.56 MHz)
Dimensions: 44.00 x 46.00 mm / 1.73 x 1.81 inch
Number of turns: 3
For more information, refer to the related product data sheet or other
relevant technical documents.
3.8 LABEL AND COMPLIANCE INFORMATION
Refer to Chapter “Compliance statements” in the user manual of the TWN4
MultiTech family and to Chapter “Integrator and host requirements” in this
integration manual for detailed label and compliance information.
3.9 TEST MODES AND ADDITIONAL TESTING REQUIREMENTS
No specific testing method has been defined by ELATEC for TWN4 MultiTech M.
The product has been tested and found in compliance with the specifications
noted on the approval certificates and other relevant approval documents.
However, the integrator is still responsible for any additional testing and
authorization process required for the end product.
It is recommended that the host device manufacturer installing the modular
transmitter perform some investigative measurements to confirm that the
resulting composite system does not exceed the spurious emissions limits or
band edge limits (e.g., where a different antenna may be causing additional
emissions). Detailed information regarding test procedure is described in the
relevant rule parts (refer to Chapter “List of applicable rules”).
3.10 ADDITIONAL TESTING, PART 15 SUBPART B DISCLAIMER
TWN4 MultiTech M is only FCC authorized for the specific rule parts (i.e., FCC
transmitter rules) listed on the grant, and the host device manufacturer is
responsible for compliance to any other FCC rules that apply to the host not
covered by the modular transmitter grant of certification. In addition, the
final host system still requires Part 15 Subpart B compliance testing with
TWN4 MultiTech M installed.
3.11 INSTALLATION
There are four holes (Ø2.7) for mechanical fixation of TWN4 MultiTech M into
the host device. Observe the minimum separation distance recommended by ELATEC
when the host device already contains other RFID devices (refer to Chapter
“Safety information”) and avoid the use of ferromagnetic screws, as these
screws could reduce the reading performance of TWN4 MultiTech M.
3.12 ELECTRICAL CONNECTION
The module can be
connected via USB, RS-232 and other interfaces. The input voltage is 4.3V to
5.5V.

3.13 PROGRAMMATION/SOFTWARE INTEGRATION
n/a
¹Hirose DF11 series, 2mm pitch or type equivalent. In case the reader module
is not connected with a cable delivered by ELATEC, the reader module can only
be connected with a cable equipped with the following connector:
Manufacturer: Shenzhen Le Qing Lin Hai Electronics Co., Ltd
Part no.: A2002-H04X2
²RS-232 operation is achieved by either closing jumper J2 on the PCB or by
connecting pin 6 and pin 8 of CNA.
INTEGRATOR AND HOST REQUIREMENTS
4.1 AUTHORIZATION REQUIREMENTS
TWN4 MultiTech M has been certified as a module and does not need further
approval, provided that the module is used in accordance with the FCC grant
conditions and no limitations or usage conditions have been defined by ELATEC.
However, the host manufacturer must ensure that the host device still complies
with all applicable regulations after the module integration.
In particular, the host integrator installing TWN4 MultiTech M into their
device must ensure that the final composite product complies with the FCC
requirements by a technical assessment or evaluation to the FCC rules,
including the transmitter operation and should refer to guidance in KDB
996369.
4.2 LABELING REQUIREMENTS
4.2.1 FCC AND ISED CANADA
Using a permanently affixed label, TWN4 MultiTech M must be labeled with its
own FCC and IC identification numbers.
FCC ID: WP5TWN4F17
IC: 7948A-TWN4F17
In case this label is not visible anymore after integration into the host
device, it is necessary to bring a label on the host device (on a visible and
accessible place) stating the FCC and IC identification numbers of the
integrated TWN4 MultiTech M:
Contains FCC ID: WP5TWN4F17
Contains IC: 7948A-TWN4F17
In case several modules have been integrated into the host device, the label
should state all FCC and IC identification numbers of the integrated modules.
Example:
“Contains FCC IDs: XXX-XXXXXXX, YYY-YYYYYYY, ZZZ-ZZZZZZZ”
“Contains transmitter modules IC: XXXXX-XXXXXX, YYYYY-YYYYYY, ZZZZZ-ZZZZZZ”
4.3 SPECIAL ACCESSORIES
Where special accessories, such as shielded cables and/or special connectors,
are required to comply with the emission limits, the instruction manual shall
include appropriate instructions on the first page of the text describing the
installation of the device.
4.4 SIMULTANEOUS TRANSMISSION
When the host product supports simultaneous-transmission operations, the host
manufacturer needs to check if there are additional RF exposure filing
requirements due to the simultaneous transmissions.
When additional application filing for RF exposure compliance demonstration is
not required (e. g. the RF module in combination with all simultaneously
operating transmitters complies with the RF exposure simultaneous transmission
SAR test exclusion requirements), the host manufacturer may do his own
evaluation without any filing, using reasonable engineering judgment and
testing for confirming compliance with out-of-band, restricted band, and
spurious emission requirements in the simultaneous-transmission operating
modes. If additional filing is required, please contact the person at ELATEC
GmbH responsible for certification of the RF module.
