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.

Love the look and having every piece of info in front of me… Better price and look [versus competition].
Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
