EVM-900-DT

HumDT™ Series RF Transceiver Module

Unspecified 

! 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 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.
