R4 Series GPS Receiver 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 2 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 A Brief Overview of GPS Connectors as part of other systems in Life Safety Situations, but 5 Client Generated Extended Ephemeris (CGEE) only with necessary and industry appropriate redundancies and 6 Time To First Fix (TTFF) in compliance with applicable safety standards, including without limitation, ANSI and NFPA standards. It is solely the responsibility 6 Module Description of any Linx customer who uses one or more of these products to 7 Backup Battery incorporate appropriate redundancies and safety standards for the Life and Property Safety Situation application. 7 Power Supply Requirements 7 The 1PPS Output 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/ 8 Antenna Considerations decoder to validate the data. Without validation, any signal from 9 Power Control another unrelated transmitter in the environment received by the module 10 Slow Start Time could inadvertently trigger the action. 10 Protocols All RF products are susceptible to RF interference that can prevent 11 Interfacing with NMEA Messages communication. RF products without frequency agility or hopping implemented are more subject to interference. This module does not 12 Interfacing with NMEA Messages have a frequency hopping protocol built in. 17 NMEA Input Messages Do not use any Linx product over the limits in this data guide. 24 Typical Applications Excessive voltage or extended operation at the maximum voltage could 25 Master Development System cause product failure. Exceeding the reflow temperature profile could 26 Board Layout Guidelines cause product failure which is not immediately evident. 27 Pad Layout Do not make any physical or electrical modifications to any Linx 28 Microstrip Details product. This will void the warranty and regulatory and UL certifications and may cause product failure which is not immediately evident. 29 Production Guidelines 29 Hand Assembly
