Appendix I: Additional EMX Information536Assumption:Upper Warning threshold is enabled.Upper Warning = 20 (degrees Celsius)Deassertion Hysteresis = 3 (degrees Celsius)"Deassertion" level = 20-3 = 17 (degrees Celsius)When the EMX detects that a temperature sensor's reading drops below20 degrees Celsius, moving from the "above upper warning" range to the"normal" range, either of the following may occur: If the temperature falls between 20 and 17 degrees Celsius, the EMXdoes NOT turn on the "deassertion" action. If the temperature drops to 17 degrees Celsius or lower, the EMXturns on the "deassertion" action to announce the end of the "aboveupper warning" state.PDView App for Viewing the EMXRaritan has developed an app that can turn your iOS or Android mobiledevice into a local display for the EMX.This app is called PDView and it can be downloaded for free.PDView is especially helpful when your EMX is not connected to thenetwork but you need to check the EMX status, retrieve basic information,or even change network settings.Requirements for using PDView: The EMX is running firmware version 3.0.0 or later. If you are using an Android device, it must support USB"On-The-Go" (OTG). An appropriate USB cable is required. For Android, you need a USB OTG adapter cable. For iOS, use the USB cable shipped with your iOS mobile device.To install PDView:1. Use your mobile device to download the PDView app from theGoogle Play or Apple's App Store.
