QS Series USB Module Data Guide Warning: Some customers may want Linx radio frequency (RF) Table of Contents products to control machinery or devices remotely, including machinery or devices that can cause death, bodily injuries, and/or property 1 Description damage if improperly or inadvertently triggered, particularly in industrial settings or other applications implicating life-safety concerns (Life and 1 Features Property Safety Situations). 1 Applications 2 Ordering Information NO OEM LINX REMOTE CONTROL OR FUNCTION MODULE SHOULD EVER BE USED IN LIFE AND PROPERTY SAFETY 2 Absolute Maximum Ratings SITUATIONS. No OEM Linx Remote Control or Function Module 3 Electrical Specifications should be modified for Life and Property Safety Situations. Such modification cannot provide sufficient safety and will void the products 4 Pin Assignments regulatory certification and warranty. 4 Pin Descriptions Customers may use our (non-Function) Modules, Antenna and 5 Module Description Connectors as part of other systems in Life Safety Situations, but 5 Theory of Operation only with necessary and industry appropriate redundancies and 7 Installing the Drivers in compliance with applicable safety standards, including without limitation, ANSI and NFPA standards. It is solely the responsibility 8 Changing the Device Descriptions of any Linx customer who uses one or more of these products to 8 Software Considerations incorporate appropriate redundancies and safety standards for the Life and Property Safety Situation application. 9 Serial Number Considerations 10 Power Supply Guidelines 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/ 10 Pad Layout decoder to validate the data. Without validation, any signal from 11 Helpful Application Notes from Linx another unrelated transmitter in the environment received by the 12 Typical Applications module could inadvertently trigger the action. 14 Production Guidelines All RF products are susceptible to RF interference that can prevent 14 Hand Assembly communication. RF products without frequency agility or hopping implemented are more subject to interference. This module does not 14 Automated Assembly 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.
