[BLUEMAX INSTALLATION INSTRUCTIONS]
Document number 2456-05 Revision 3

Introduction
1.1
The BlueMAX module
The BlueMAX module captures serial data from an Avidyne engine monitoring system
and streams it via Bluetooth Low Energy to portable devices. This enables
supplementary engine data to be displayed and logged on a portable device.
The BlueMAX installation is not intended to replace primary engine instruments.
Optionally, the module may also be connected to the serial GPS data transmitted by the
#1 GPS navigator to the MFD, providing navigation data to the portable device via
Bluetooth to enable calculations such as fuel at destination.
1.2
Applicability
The BlueMAX module is intended for installation into aircraft already fitted with an
Avidyne engine monitoring system, utilizing either a Data Acquisition Unit (DAU) or a
Serial Interface Unit (SIU.) The majority of such installations are in Cirrus SR22 and
SR20 aircraft, and these instructions relate specifically to those models.
