1.1 System Description:

The MVP-50P Glass Panel Engine Monitor installation consists of four major components: the MVP Display,
the Engine Data Converter (EDC-33P), the Probes, Transducers & Modules, and the Wiring and Extension
Cables.

1.1.1

1.1.1 MVP Display:

MVP Display:

The MVP-50P (MVP) display measures 5.55" wide by 5.15" high by 2.4" deep and is designed to be
mounted from behind the aircraft instrument panel. The MVP could be mounted onto a sub-panel
which would then be mounted to the aircraft instrument panel from the front. The installation location
of the MVP display on the aircraft panel and the method used to install the display will be a primary
consideration in your decision to install the MVP.

The 25-pin D-sub connector on the back of the MVP display is used to interface the MVP to the EDC-
33P, Power & Ground, GPS, Master Warning and Caution Lights and Audio Panel (experimental only).

1.1.2

1.1.2 EDC-33P:

EDC-33P:

The EDC-33P (Engine Data Converter, "EDC") converts all of the engine and aircraft system signals
into serial data. This data is transmitted to the MVP display via two wires (RS422). If a second EDC is
installed, one of the EDC data lines will be connected to a RS232 channel on the MVP. The EDC
measures 4.5" long by 3.5" wide by 2.2" high and is to be mounted on cockpit side of the firewall or in
an equipment bay. The EDC reduces the wire bundle to the instrument panel by over 100 wires. There
are three 37-pin D-sub connectors that interface the EDC to the various probes, transducers and mod-
ules.

The EDC’s temperature and fuel level inputs can be used to monitor voltage outputs from almost any
transducer. In this way almost any function can be displayed on the MVP.

Up to two EDC’s can be connected to the MVP display. This significantly increases the total number of
functions that can be displayed on the MVP.
