TT Series Remote Control and Sensor Transceiver Data Guide Warning: Linx radio frequency R) products may be Table of Contents used 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 1 Features settings or other applications implicating life-safety concerns. No Linx Technologies product is intended for use in any application without 2 Ordering Information redundancies where the safety of life or property is at risk. 2 Electrical Specifications 4 Absolute Maximum Ratings The customers and users of devices and machinery controlled with RF products must understand and must use all appropriate safety 5 Transceiver Timings procedures in connection with the devices, including without limitation, 6 TRM-xxx-TT Typical Performance Graphs using appropriate safety procedures to prevent inadvertent triggering by 12 Pin Assignments the user of the device and using appropriate security codes to prevent triggering of the remote controlled machine or device by users of other 12 Pin Descriptions remote controllers. 14 Theory of Operation 15 Module Description 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/ 16 Basic Hardware Operation decoder to validate the data. Without validation, any signal from 18 Transceiver Operation another unrelated transmitter in the environment received by the module 19 Transmit Operation could inadvertently trigger the action. 19 Receive Operation All RF products are susceptible to RF interference that can prevent 20 The Pair Process communication. RF products without frequency agility or hopping 21 Permissions Mask implemented are more subject to interference. This module does have 21 Acknowledgement a frequency hopping protocol built in, but the developer should still be aware of the risk of interference. 22 Mode Indicator 22 Reset to Factory Default Do not use any Linx product over the limits in this data guide. 23 Using the RSSI Line Excessive voltage or extended operation at the maximum voltage could cause product failure. Exceeding the reflow temperature profile could 23 Using the LATCH EN Line cause product failure which is not immediately evident. 24 Using the Low Power Features 24 Using the LVL ADJ Line Do not make any physical or electrical modifications to any Linx product. This will void the warranty and regulatory and UL certifications 26 Receiver Duty Cycle and may cause product failure which is not immediately evident. 27 Power Supply Requirements 28 The Command Data Interface 31 Frequency Hopping 32 Usage Guidelines for FCC Compliance
