Wiring & Extension Cables:
The extension cables and wiring provide the connections from the probes, modules or direct connections
to the EDC inputs. Once the Wiring and Extension Cables are installed into the aircraft they become
semi-permanent. Everything else (MVP, EDC, Probes and Modules) can be easily disconnected and
removed.
1.2 Operational Overview:
The MVP system measures a primary engine or aircraft function using a probe or transducer and displays that
function on the MVP screen using the following steps:
A. A probe is mechanically connected to the aircraft and electrically connected to an EDC input. The
pre-wired harness provides most of the electrical connections from the probes to the EDC inputs.
B. The EDC converts the signals from the probes to a digital format (RS422) and sends the data to the
MVP. The EDC has 33 inputs. Many of these inputs can be used to monitor various types of func-
tions.
C. The MVP receives the data from the EDC and the data is processed through the MVP as follows:
1. The data received for each EDC input is assigned a function name and probe. Function
names and probes are set up for each EDC input in System Configuration Screen #1. As-
signing a probe provides specific calibration algorithms. These algorithms can be modified
in System Configuration Screen #5. Some functions have special calibration/setup screens
(Bar Graph, Fuel Tank Calibration, Tach Time, Engine Hours, Flight Time, Pressure Altitude,
Horsepower, Flaps, Trim, etc.).
2. The function is then placed on the Main or System Screen of the MVP. System Configura-
tion Screens #2 or #3 allow the placement of the function to be selected for either the Main
or System screen.
3. The analog and/or digital display of the function (with redlines, limits, colors, etc) is de-
picted on the appropriate screen. Redlines, limits, colors, units, blinking, master warnings
and voice files can be set up for any function in Configuration Screen #4.
Much of the setup for the certified MVP is done at the factory and cannot be changed by the pilot or installer.

1.3 Installation Overview:
For a twin engine installation refer to appendix A8.0. The installer should start the installation by reviewing
the EDC Wiring Work Sheets. There are three work sheets, one for each of the 37-pin D-Sub connectors on
the EDC. The work sheets are packaged with each of the three EDC wire harnesses. The work sheets provide
a list of the functions and probes/transducers included with this kit. The installation is achieved by performing
the following steps:
