   SV-EMS-220/221 Installation and Configuration 
SkyView System Installation Guide - Revision R    7-61 
The alarm type for oil temperature is the “self-clearing” type. 
EMS Sensor Definitions, Mapping, and Settings 
All sensors must be defined, mapped to SV-EMS-220/221 pins, and have their 
settings configured. This section describes how sensors are defined, mapped, and 
set in SkyView. 
EMS Sensor Definitions 
All EMS sensor installations require a SkyView Sensor Definitions file. This file provides 
characterizations of all sensors that SkyView supports, and is occasionally updated to add 
additional supported sensors and correct issues with existing sensors. The most current version 
of the SkyView Sensor Definitions file is preloaded onto each display prior to shipment. The 
most current version of the SkyView Sensor Definitions file can be downloaded from 
http://downloads.dynonavionics.com. 
If you have more than one SkyView display, and the SkyView Sensor Definitions file on each 
display is different from one another, a warning message will be displayed: 
EMS SFG FILE MISMATCH. 
If you need to update the SkyView Sensor Definitions file, download the file and use the 
instructions found in the How to Load and Delete Files Section. 
The SkyView Sensor Definitions file has a .sfg file extension. This file is not 
automatically shared between displays. It must be loaded onto each display in the 
system. 
EMS Sensor Input Mapping 
In order to save installers time, Dynon provides preconfigured sensor mapping and 
settings files which support popular four and six-cylinder engine installations. All of 
the installations mentioned in the Example Engine Sensor and Transducer 
Installations Section have preconfigured mapping and settings files that are 
available for download at http://downloads.dynonavionics.com. 
Settings for SV-EMS-220/221 pin mapping, ranges, widget graphical properties, 
etc. are automatically shared between multiple SkyView displays. 
If your engine installation is listed in the Example Engine Sensor and Transducer Installations 
Section, we recommend you install one of the sensor mapping and settings files onto the 
SkyView display using the instruction found the How to Load and Delete Files Section. Then 
update or modify the sensor map and settings based on your installation.
