MFR Model# EMU912IS

Overview

The EMU 912iS embeds into the Rotax® 912iS aero engine system and provides all indications available through the redundant CANaerospace network interface implemented for the 912iS Engine Control Unit (ECU). The EMU 912iS functionality includes continuous monitoring of the network health status, and the indication of all ECU generated warning messages. GPS/Galileo data is recorded together with engine data. All data is correlated and may be visualized using Google Earth. An optional fuel pressure sensor is included in the data display.

Display Pages


The EMU 912iS supports several display pages, providing detailed information about engine performance and status, CANaerospace network health and the data recording status. The MAIN page provides assistance for the engine cold start power setting.

Installation


The EMU912iS integrates seamlessly into the Rotax® 912iS wire harness. The Installation is exceptionally simple. Only three connectors with 9 wires are required to provide the full functionality. All interfaces are isolated from each other for electromagnetic compatibility with other systems.

Data Storage, System Configuration and Software Upgrades


The EMU 912iS software automatically records all ECU messages transmitted on the redundant Rotax® 912iS CANaerospace networks. The network interfaces operate under sustained 100% bus load without dropping any messages and provide a 31.25 nanosecond time stamp resolution. The integrated, front panel accessible SDHC interface is used for data acquisition storage, system configuration information and software upgrades. The SDHC card slot accepts memory cards with sizes up to 32GBytes. Software upgrades may be downloaded from the Stock Flight Systems website and placed on SDHC card for upgrading the EMU 912iS with the current software version. The EMU 912iS is delivered with the Engine Monitoring Debriefing System (EMDS) software, a powerful toolbox for Linux, MacOS and Windows XP/7 which uses the data files recorded on the EMU 912iS SDHC card. Among other features, EMDS allows data visualization in engineering formats and the export of the data into other formats like .kml for Google Earth. EMDS upgrades for the operating systems mentioned above may be downloaded from the Stock Flight Systems website.

GPS/Galileo Sensor


The EMU 912iS combined GPS/Galileo sensor adds time correlated 4Hz GPS/Galileo data to the engine data recording, allowing to generate performance data from the combination of engine data with position, ground speed, height and time. Flight pathes together with engine data can be visualized in Google Earth. GPS/Galileo date and UTC information provides the time base for the recording files.
