Product Overview
BC-5 Overview

Translate
The BC-5 Bus Converter Instrument is capable of accepting and translating input from several different communication protocols, including CAN, ARINC, Bluetooth, RS-232 and RS-422. It doesn’t matter if the data is sent from an Air Data Computer, Engine Data Converter, FADEC or another device, the BC-5 can accept data from multiple sources.
Calculate
The BC-5 isn’t just a passive receiver of data. It can perform calculations on data received, and make decisions based on complex comparisons and situations.
Process
After the BC-5 receives data and performs all necessary comparisons and calculations, the data is output in any specified format. The processed data can be sent to many different platforms. Some customers use the BC-5 to accept data from several inputs to display data on our MVP-50, others have used the BC-5 to drive existing OEM systems, and yet other customers have used the BC-5 to be a translator for both types of systems.
Record
EI’s MVP and CGR systems include onboard data record, but some clients want to use the BC-5 as an oboard data recorder. Certain configurations of the BC-5 allow for thousands of hours of data to be recorded.
Control
The BC-5 has the capability of driving control lines High or Low, based on defined criteria. If a parameter slips past a redline, if a timer reaches its limit, if a differential is exceeded between compared functions, or any other set of conditions is met based on processed data, the BC-5 can be configured to turn on or off external control lines.
Example Applications
The BC-5 can interface with many different system, including EI products, custom and OEM systems. If you need data monitored, manipulated, displayed or recorded, chances are good the BC-5 is the answer to your needs.

While the installation is not quite done yet, I have seen the unit in my aircraft with the engine running and the monitor producing numbers. It looks very good and I cannot wait to go flying with it!
[Customer service] is great!

The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
Awesome product. Fast easy installation.

Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.

Great customer service!
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.

Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
