Aviation's Panel Mount Avionics Installation Leader

The SV-EMS-220 Module provides the interface between a SkyView Display and the engine and aircraft sensors. It allows the SkyView System to continuously monitor all power plant and aircraft systems in a highly automated manner. The EMS Module integrates up to 16 different types of gauges all in one highly compact design. Any parameter falling outside its predefined limits are automatically brought to the attention of the pilot for immediate remediation. Safety is enhanced two fold; first, by reducing the pilot's workload and secondly by early detection and notification of foreseen trouble.

Flexibility: The SkyView System is highly configurable for you to design the exact Engine Monitoring display you want. Common engine configurations come standard, but an easy to use setup menu allows you to choose exactly which sensors, displays, ranges and alarms you want.

Some of the parameters you can measure with the SkyView EMS include:

  • Tach
  • Manifold Pressure
  • Oil Pressure
  • Oil Temperature
  • Fuel Flow
  • Fuel Pressure
  • CHT
  • EGT
  • Voltage
  • Current
It also can monitor discrete sensors for:
  • Trim Position
  • Flap Position
  • And other aircraft parameters


The SV-EMS-220 should be mounted in the avionics bay near the firewall. NOTE: it cannot be mounted on the engine side of the firewall.


The SV-EMS-220 has two connectors, a D37 and a D25. The D37 contains dedicated RPM, Voltage, Fuel Flow, Current, MAP, general purpose inputs, and two thermocouple inputs (for extra CHTs and EGTs). The D25 has twelve thermocouple temperature inputs for EGTs and CHTs). The EMS Module is connected to a SkyView Display via a D9 connector.

Engine Sensor Kits

The SV-EMS-220 can use the Dynon Engine Sensor Kits for the 4 and 6 cylinder Lycoming, Continental, Jabiru, and Rotax engines. The Wiring Harnesses supplied with these kits fit the SV-EMS-220 connectors. Other engines are supported, although the installer will have to determine the correct sensors and wiring to connect to the EMS Module.

More than Six Cylinders

The SkyView System supports one or two EMS Modules. A second EMS module can be used to monitor a second engine in twin aircraft applications (two displays are required in this configuration - one engine is monitored on each display). Or, you can use a second EMS module to add more EGT and CHT inputs to allow full monitoring of large radial engines.

Design Considerations

A SkyView Network Cable is used to connect an ADAHRS Module to a Display. One SV-EMS-22X will provide data to as many displays as are connected in the SkyView System.
