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 Absolute Maximum Ratings 3 Electrical Specifications The customers and users of devices and machinery controlled with RF products must understand and must use all appropriate safety 6 Typical Performance Graphs procedures in connection with the devices, including without limitation, 11 Module Description using appropriate safety procedures to prevent inadvertent triggering by 11 Theory of Operation 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 Assignments remote controllers. 12 Pin Descriptions 14 Sending Data Do not use this or any Linx product to trigger an action directly 14 The Data Input from the data line or RSSI lines without a protocol or encoder/ decoder to validate the data. Without validation, any signal from 15 The Data Output another unrelated transmitter in the environment received by the module 15 Using the RSSI Line could inadvertently trigger the action. This module does not have data 16 Using the T/R SEL Input validation built in. 16 Using the Low Power Features All RF products are susceptible to RF interference that can prevent 17 Using the READY Output communication. RF products without frequency agility or hopping 17 Using the LVL ADJ Line implemented are more subject to interference. This module does not have frequency agility built in, but the developer can implement 18 Baud Band Selection frequency agility with a microcontroller and the example code in Linx 19 Channel Selection Reference Guide RG-00101. 20 European Transmission Rules Do not use any Linx product over the limits in this data guide. 23 Typical Applications Excessive voltage or extended operation at the maximum voltage could 24 Power Supply Requirements cause product failure. Exceeding the reflow temperature profile could 24 Antenna Considerations cause product failure which is not immediately evident. 25 Protocol Guidelines Do not make any physical or electrical modifications to any Linx 26 Interference Considerations product. This will void the warranty and regulatory and UL certifications 27 Pad Layout and may cause product failure which is not immediately evident. 27 Board Layout Guidelines 29 Microstrip Details
