HumRC TM Series Remote
Control and Sensor Transceiver
Data Guide
! 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.
2^
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.
18^
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.

HumRC TM Series Remote Control
and Sensor Transceiver
Data Guide
Description
0.55"
(13.97)
The HumRC™ Series transceiver is designed
for reliable bi-directional remote control
0.45"
applications. It consists of a highly optimized (11.43)
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. It also provides
Figure 1: Package Dimensions
much more noise immunity than narrowband
radios, making the module suitable for use in noisy environments.
0.07"
(1.78)
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 902 to 928MHz and 2,400 to 2,483MHz 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.
Housed in a compact reflow-compatible SMD package, the transceiver
requires no external RF components except an antenna, which greatly
simplifies integration and lowers assembly costs.
