Description
The EVM-915-DTS features our powerful
and popular TRM-915-DTS module in a FCC
modular approved solution. It is designed
to greatly simplify implementation of the
TRM-915-DTS module into a working design
without the complications of FCC testing.
The module combines a state-of-the art low
power wireless transceiver with a powerful multipoint-to-multipoint protocol
controller to form a transparent wireless communication solution capable
of replacing wires in almost any RS-232/422/485 application. With a 111
dB link budget and very low power operation modes, the TRM-915-DTS
module is excellent for AMR, RFID, Home Automation, and any other
application requiring long range (<1500ft. , line of sight) and long
battery life.
The module is designed to be totally transparent. No special addressing
or formatting of data is required. Data is validated using an internally
generated CRC-16 and encoded using a proprietary algorithm.
Multiple modules can operate on the same channel because of the built-in
carrier-sense-multiple-access (CSMA) protocol.

Warning: Linx radio frequency (“RF”) products may be used to
control machinery or devices remotely, including machinery or devices
that can cause death, bodily injuries, and/or property damage if
improperly or inadvertently triggered, particularly in industrial settings
or other applications implicating life-safety concerns. No Linx
Technologies product is intended for use in any application without
redundancies where the safety of life or property is at risk.
The customers and users of devices and machinery controlled with
RF products must understand and must use all appropriate safety
procedures in connection with the devices, including without limitation,
using appropriate safety procedures to prevent inadvertent triggering
by the user of the device and using appropriate security codes to
prevent triggering of the remote controlled machine or device by users
of other remote controllers.
All RF products are susceptible to RF interface that can prevent
communication. RF products without frequency agility or hopping
implemented are more subject to interference. This module does
not have frequency agility built in, but the developer can implement
frequency agility with a microcontroller and the example code in Linx
Reference Guide RG-00101.
Do not use any Linx product over the limits in this data guide.
Excessive voltage or extended operation at the maximum voltage
could cause product failure. Exceeding the reflow temperature profile
could cause product failure which is not immediately evident.
Do not make any physical or electrical modifications to any
Linx product. This will void the warranty and regulatory and UL
certifications and may cause product failure which is not immediately
evident.

Usage Guidelines for FCC Compliance
The EVM-915-DTS modules have been awarded a FCC and Anatel
modular approvals. That means that this module, when integrated into
your end product, requires no FCC part 15 or Anatel testing as long as the
following guidelines are met. Failure to meet any of the following guidelines
will prevent the inheritance of the FCC and IC modular certifications.
Antenna Selection
In order to maintain compliance with FCC and Anatel regulations, an
antenna with no more than 3dBi gain must be used. This module has been
tested with the following antennas:
When operating in DTS mode the module may be used with any of the
above antennas and maintain the requirements of the FCC grant. When
operating the module in LP mode, it must be used with the approved ¼
wave antenna. The module may not be used with the ½ wave dipole
antenna in LP mode.
An approved antenna must be directly attached to the module’s reverse-
polarity SMA connector in the final application to inherit the FCC and Anatel
modular certification.
Module Modication
The module must not be physically altered in any way. If any connections
are made to the modules that bypass the module pins, socket or antenna
connector, neither the FCC nor Anatel modular certification can be
inherited.
End Product Labeling Requirements
Pursuant to FCC public notice DA 00-1407, the end product must be
labeled on its exterior with the following:
“Contains FCC ID: Q7V-3F090003X”
Antenna Selection
Linx Part No. Antenna Type Antenna Gain
ANT-916-CW-QW RP ¼ Wave Helical 2dBi
ANT-916-CW-HW RP ½ Wave Dipole 2.5dBi
Figure 8: Antenna Selection
Additional FCC Testing Requirements
While the module’s FCC certification can be inherited if the guidelines
are met, additional testing will be required to achieve full FCC compliance
for the end-product. The integrator is required to perform unintentional
radiator testing on the final product per FCC sections 15.107 and 15.109.
Additional product-specific testing might be required. Please contact the
FCC regarding regulatory requirements for your application. Ultimately is it
the integrator’s responsibility to show that their product complies with the
regulations applicable to their product.
Customer FCC Warning Requirements
The end-product’s user’s manual must contain the following or equivalent
statements.
FCC NOTICE (Containing FCC ID: Q7V-3F090003X)
The RF module (FCC ID: Q7V-3F090009X) contained within this device complies with the
rules set forth in Part 15 by the Federal Communications Commission. Operation is subject
to the following conditions:
1. This device may not cause harmful interference
2. This device must accept any interference received, including interference that may
cause undesired operation.
3. An approved antenna must be directly coupled to the module’s RP-SMA
connector.
4. The module must not be modied in any way. Coupling of external circuitry must not
bypass the provided connectors.
5. The antenna used for this transceiver must not be co-located or operating in
conjunction with any other antenna or transmitter.
Any changes or modications could void the user’s authority to operate the
equipment.

FCC Statements of Modular Compliance
FCC NOTICE (FCC ID: Q7V-3F090009X)
This device complies with the rules set forth in Part 15 by the Federal
Communications Commission. Operation is subject to the following two conditions:
1. This device may not cause harmful interference
2. This device must accept any interference received, including interference that may
cause undesired operation.
Any changes or modications not expressly approved by Linx Technologies could void
the user’s authority to operate the equipment.
The EVM-915-DTS module is provided with an inheritable FCC Modular
Certication. This certication may be inherited in an end-user product, negating the
need for FCC part 15 intentional radiator testing on this module, provided that the
following guidelines are met:
1. An approved antenna must be directly coupled to the module’s RP-SMA connector.
2. The module must not be modied in any way. Coupling of external circuitry must not
bypass the provided connectors.
3. End product must be externally labeled with “Contains FCC ID: Q7V-3F090009X”
4. The end product’s user’s manual must contain an FCC statement equivalent to that
listed on page 11 of this manual.
5. The antenna used for this transceiver must not be co-located or operating in
conjunction with any other antenna or transmitter.
6. The integrator must not provide any information to the end-user on how to install or
remove the module from the end-product.
The integrator is required to perform unintentional radiator testing on the nal product
per FCC sections 15.107 and 15.109.
