products 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 (“Life and
Property Safety Situations”).

NO OEM LINX REMOTE CONTROL OR FUNCTION MODULE
SHOULD EVER BE USED IN LIFE AND PROPERTY SAFETY
SITUATIONS. No OEM Linx Remote Control or Function Module
should be modified for Life and Property Safety Situations. Such
modification cannot provide sufficient safety and will void the product’s
regulatory certification and warranty.
Customers may use our (non-Function) Modules, Antenna and
Connectors as part of other systems in Life Safety Situations, but
only with necessary and industry appropriate redundancies and
in compliance with applicable safety standards, including without
limitation, ANSI and NFPA standards. It is solely the responsibility
of any Linx customer who uses one or more of these products to
incorporate appropriate redundancies and safety standards for the Life
and Property Safety Situation application.
Do not use this or any Linx product to trigger an action directly
from the data line or RSSI lines without a protocol or encoder/
decoder to validate the data. Without validation, any signal from
another unrelated transmitter in the environment received by the
module could inadvertently trigger the action.
All RF products are susceptible to RF interference that can prevent
communication. RF products without frequency agility or hopping
implemented are more subject to interference. This module does not
have a frequency hopping protocol built in.

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.

TM Series GNSS Receiver
Evaluation Module
User's Guide
Figure 1: TM Series Evaluation Module
Description
The TM Series GNSS receiver module is a self-contained high-performance
Global Satellite Navigation System receiver. Based on the MediaTek
chipset, it can simultaneously acquire and track multiple satellite
constellations. These include the United States GPS system, Europe’s
GALILEO, Russia’s GLONASS and Japan’s QZSS.
The module provides exceptional sensitivity, even in dense foliage and
urban canyons. It’s very low power consumption helps maximize runtimes
in battery powered applications. Hybrid ephemeris prediction can be used
to achieve cold start times of less than 15 seconds. The module outputs
standard NMEA data.
The evaluation module contains the surface mount TM Series GNSS
module, SMA connector and a ferrite bead (used to supply power to an
external active antenna, such as the Linx SH Series active GPS antenna)
on a single board with through-hole headers. This small board makes
prototyping with the TM Series module very easy.
