SV-EMS-220/221 Installation and Configuration
SkyView System Installation Guide - Revision AA 7-5
SkyView Network Connection
If you have installed two SV-EMS-220s or two SV-EMS-
221s to monitor a 9-cylinder (or more) engine or dual
engines, Dynon Avionics offers the SV-NET-SPL “Splitter”
Cable – see Figure 60. This cable allows a single (more
economical, lower weight) SkyView Network Cable to be
run to the location of dual SV-EMS-220/221s and then
“split” the SkyView Network signals to each SV-EMS-
220/221.
Connect the EMS module to the SkyView network using
the hardware mentioned in the SkyView System Construction Section or using equivalent
hardware.
If you have to install a connector on the end of a network cable, insert all pins into the D9
connector. Reference Appendix C: Wiring and Electrical Connections for details on connector
pinouts and wire colors.
Remember to configure the network after connecting all modules to a display.
SkyView EMS Sensor Definition and Configuration Files
The SkyView EMS utilizes a file to define sensor behavior and a file to map those sensors to pins
on the SV-EMS-220/221 and configure the sensors’ onscreen visual representations or widgets.
The sensor definition file is preloaded onto all SkyView displays during manufacture and may
need to be updated. The sensor mapping and configuration file is not preloaded onto displays
and must be downloaded and installed by the user. Reference the EMS Sensor Definitions,
Mapping, and Settings Section for more information.
Engine Sensor and Transducer Planning
In order to save installers time, Dynon Avionics provides preconfigured sensor
mapping and settings files as well as premade engine sensor connection wire
harnesses. These resources support many popular four and six-cylinder engine
installations. Reference the Example Engine Sensor and Transducer Installations
Section for examples.
Sensor mapping and settings files map SV-EMS-220/221 pins to engine
transducers and sensors and also configure onscreen engine gauges with
appropriate graphical settings. Reference http://downloads.dynonavionics.com
for more information.
The SV-EMS-220/221 is compatible with a wide range of sensors and transducers. Reference
Table 100 on page 22-3 for a list of engine sensors and transducers that are known to be
