FM 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 Include 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 6 Time To First Fix (TTFF) only with necessary and industry appropriate redundancies and 6 Module Description in compliance with applicable safety standards, including without limitation, ANSI and NFPA standards. It is solely the responsibility 7 Backup Battery of any Linx customer who uses one or more of these products to 7 Power Supply Requirements incorporate appropriate redundancies and safety standards for the Life and Property Safety Situation application. 7 The 1PPS Output 7 Hybrid Ephemeris Prediction (AGPS) 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. 11 Interfacing with NMEA Messages All RF products are susceptible to RF interference that can prevent 12 NMEA Output Messages communication. RF products without frequency agility or hopping implemented are more subject to interference. This module does not 18 Input Messages have a frequency hopping protocol built in. 32 Typical Applications Do not use any Linx product over the limits in this data guide. 33 Microstrip Details Excessive voltage or extended operation at the maximum voltage could 34 Board Layout Guidelines cause product failure. Exceeding the reflow temperature profile could 35 Pad Layout cause product failure which is not immediately evident. 36 Production Guidelines Do not make any physical or electrical modifications to any Linx 36 Hand Assembly product. This will void the warranty and regulatory and UL certifications and may cause product failure which is not immediately evident. 36 Automated Assembly 38 Master Development System
