TM HumDT Series RF Transceiver 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). 2 Ordering Information NO OEM LINX REMOTE CONTROL OR FUNCTION MODULE 2 Absolute Maximum Ratings SHOULD EVER BE USED IN LIFE AND PROPERTY SAFETY 3 Electrical Specifications SITUATIONS. No OEM Linx Remote Control or Function Module 5 Typical Performance Graphs should be modified for Life and Property Safety Situations. Such modification cannot provide sufficient safety and will void the products 10 Pin Assignments regulatory certification and warranty. 10 Pin Descriptions Customers may use our (non-Function) Modules, Antenna and 12 Theory of Operation Connectors as part of other systems in Life Safety Situations, but 13 Module Description only with necessary and industry appropriate redundancies and in compliance with applicable safety standards, including without 14 Frequency Agility limitation, ANSI and NFPA standards. It is solely the responsibility of any 15 Networking Linx customer who uses one or more of these products to incorporate 16 Initialization and Joining appropriate redundancies and safety standards for the Life and Property Safety Situation application. 17 Addressing 18 GPIO Configuration 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/ 18 Baud Rate decoder to validate the data. Without validation, any signal from 19 Using the Low Power Features another unrelated transmitter in the environment received by the module could inadvertently trigger the action. 19 External Amplifier Control 20 Encryption All RF products are susceptible to RF interference that can prevent 21 Restore Factory Defaults communication. RF products without frequency agility or hopping implemented are more subject to interference. This module does not 22 Command Data Interface have a frequency hopping protocol built in. 24 The Command Data Interface Command Set Do not use any Linx product over the limits in this data guide. 53 Typical Applications Excessive voltage or extended operation at the maximum voltage could 54 Power Supply Requirements cause product failure. Exceeding the reflow temperature profile could cause product failure which is not immediately evident. 54 Antenna Considerations 55 Helpful Application Notes from Linx Do not make any physical or electrical modifications to any Linx 56 Interference Considerations product. This will void the warranty and regulatory and UL certifications and may cause product failure which is not immediately evident. 57 Pad Layout 57 Board Layout Guidelines
