Warning:
Some customers may want Linx radio frequency (“RF”)
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 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.

Series Evaluation Module
Description
The HumRC
TM
Series transceiver is designed for reliable bi-directional
remote control applications. It consists of a highly optimized Frequency
Hopping Spread Spectrum (FHSS) RF transceiver and integrated remote
control transcoder. The FHSS system allows higher RF output power and,
therefore, longer range than narrowband radios.
Eight status lines can be set up in any combination of inputs and outputs
for the transfer of button or contact states. A selectable acknowledgement
indicates that the transmission was successfully received. Versions are
available in the 2400 to 2483MHz frequency bands.
Primary settings are hardware-selectable, which eliminates the need for an
external microcontroller or other digital interface. For advanced features,
optional software configuration is provided by a UART interface; however,
no programming is required for basic operation.
The evaluation module contains the surface mount HumRC
TM
Series
transceiver module and an MMCX connector on a single board with
through-hole headers. This small board simplifies prototyping with the
HumRC
TM
Series module.

Description
No Electrical Connection. Do not connect
any traces to these lines.
Pull this line high to enable the module to
send an acknowledgement message after a
valid control message has been received.
A high on this line initiates the Pair process,
which causes two units to accept each
other’s transmissions. It is also used with
a special sequence to reset the module to
factory default configuration.
Command Data Out. Output line for the se-
rial interface commands
Low Noise Amplifier Enable. This line is
driven high when receiving. It is intended to
activate an optional external LNA.
Supply Voltage
Level Adjust. The voltage on this line sets
the transmitter output power level.
This line sets the input/output direction for
status lines S0–S3. When low, the lines are
outputs; when high they are inputs.
Power Amplifier Enable. This line is driven
high when transmitting. It is intended to acti-
vate an optional external power amplifier.
This line sets the input/output direction for
status lines S4–S7. When low, the lines are
outputs; when high they are inputs.
Status Lines. Each line can be configured as
either an input to register button or contact
closures or as an output to control applica-
tion circuitry.
This line goes high when the module
receives an acknowledgement message
from another module after sending a control
message.

Description
50-ohm RF Antenna Port
Ground
This line indicates module activity. It can
source enough current to drive a small
LED, causing it to flash. The duration of the
flashes indicates the module’s current state.
This line resets the module when pulled low.
It should be pulled high for normal operation.
Command Data In. Input line for the serial
interface commands. If serial control is not
used, this line should be tied to ground
or POWER_DOWN to minimize current
consumption.
Power Down. Pulling this line low places the
module into a low-power state. The module
is not functional in this state. Pull high for
normal operation. Do not leave floating.
If this line is high, then the status line
outputs are latched (a received command
to activate a status line toggles the output
state). If this line is low, then the output lines
are momentary (active for as long as a valid
signal is received).
