EVM-915-250
Data Guide
Description
(Preliminary)
The EVM-915-250 evaluation module
supports developments with the TRM-
915-R250 embedded radio module.
The EVM-915-250 module combines a
state-of-the art low power wireless
transceiver with a powerful multipoint-
Figure 1: EVM-915-250-FCx
to-multipoint protocol controller to form a
complete wireless communication solution. With a simple UART interface,
a 130dB link budget and very low power operation modes. The module is
excellent for Automatic Meter Reading (AMR), fleet management, RFID, gas
and oil sensing, Home Automation, and many other cable replacement
applications requiring long range and long battery life.
The module can operate as a transparent wire replacement solution.
It can also operate in a peer-to-peer networked mode that supports node
addressing and assured delivery. The module is designed to be totally
transparent. Data is validated using an internally generated CRC-16 and
encoded using a proprietary Frequency Hopping Spread Spectrum
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.
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.
