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.
7 Power Supply Requirements
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 have
a frequency hopping protocol built in, but the developer should still be
aware of the risk of interference.
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.

Data Guide
Figure 1: HumPROTM Series Evaluation Module
Description
The HumPROTM Series is a frequency hopping spread spectrum (FHSS)
transceiver designed for the reliable transfer of digital data. It has a very
fast lock time so that it can quickly wake up, send data and go back to
sleep, saving power consumption in battery-powered applications that
have strict power budgets.
The HumPROTM Series module has several features that make the data
transfer reliable. A Carrier Sense Multiple Access (CSMA) routine ensures
that the channel is clear before the module begins transmitting data.
Automatic acknowledgements ensure that the remote side got valid data.
Multiple hopping patterns enable multiple systems to operate in proximity
without interference. A standard UART interface is used for module
configuration and data transfer.
All HumPROTM Series modules have a unique 32-bit serial number that
can be used as an address. Source and destination addressing support
point-to-point and broadcast links. Address masking by the receiving
module allows for creating subnets. More advanced networks can also be
implemented.
The evaluation module contains the surface mount HumPROTM Series
transceiver module and an MMCX connector on a single board with
through-hole headers. This small board simplifies prototyping with the
HumPROTM Series module.

low-dropout regulator which allows operation
over a wide input voltage range. Despite this
regulator, it is still important to provide a supply
that is free of noise. Power supply noise can
significantly affect the module’s performance, so
providing a clean power supply for the module
should be a high priority during design.
