Introduction
The AHRS-2 / AHRS-4 / MAG-2 is a 3 1/8” (80mm) sunlight readable color display instrument providing a display for an
artificial horizon reference system (AHRS), an advanced digital compass, or both depending on which sensor packages is
connected.
The AHRS-2 is an attitude display for the external MGL-Avionics SP-7 attitude sensor package. The AHRS-2 re-
quires the MGL-Avionics SP-6 compass sensor package to display heading.
The AHRS-4 is a self contained attitude display with built in sensors. The AHRS-4 does not require the MGL-
Avionics SP-7 sensor package in order to display the attitude, but requires the MGL-Avionics SP-6 compass sen-
sor package to display heading. The AHRS-4 can output CAN bus messages to emulate the MGL Avionics SP-7
sensor package.
The MAG-2 is a compass display for the external MGL-Avionics SP-6 compass sensor package.
The AHRS-2 / AHRS-4 / MAG-2 can be setup to display the following:
•
Compass with optional slip indicator (requires MGL Avionics SP-6 sensor package)
•
Horizon with optional slip, turn indicator & G-Force (requires the MGL Avionics SP-7 if using the AHRS-2)
•
Turn and bank indicator (requires the MGL Avionics SP-7 if using the AHRS-2)
•
Combined compass and horizon display with bank indicator, optional slip indicator & G-Force (requires MGL
Avionics SP6 & the Avionics SP-7 if using the AHRS-2)
1 Features
•
Large 2.6” high resolution 320x240, IPS (fully viewable in all directions), sunlight readable color LCD dis-
play
• AHRS-2 (Artificial horizon reference system (AHRS) display unit with slip indication, turn and bank and G-
Force indication), requires the MGL Avionics SP-7 sensor packages
• AHRS-4 (Artificial horizon reference system (AHRS) display unit with slip indication, turn and bank and G-
Force indication) complete with built in attitude sensors. The AHRS-4 does not require the MGL Avionics
SP-7 sensor package to display attitude.
• Advanced magnetic compass with a course steering feature and slip indication
• Can be setup as an individual compass display, artificial horizon or both
• The AHRS-2 / AHRS-4 / MAG-2 is connected to the AHRS / Compass sensor packages by a simple CAN
bus interface. This allows for the optimum placement of the sensor packages in the aircraft
• More then one AHRS-2 / AHRS-4 / MAG-2 unit can be connected onto the CAN bus. This allows the com-
pass, artificial horizon and the turn and bank indicator to be displayed on different units
• G-Force indicator (MGL Avionics SP-7 required if using the AHRS-2)
• Built in NMEA GPS Viewer
• Automatic or manual magnetic variation calculation
• Sunset and sunrise time display
• Displays time & date, GPS altitude, SOG, COG, latitude and longitude when using an external NMEA com-
patible GPS receiver
• Includes a RS232 serial output for interfacing to external equipment e.g dataloggers etc.
• The AHRS-4 can output CAN bus messages to emulate the MGL Avionics SP-7 sensor package.
• Standard 3 1/8” (80mm) aircraft enclosure (can be front or rear mounted)
• The LED backlight can automatically adjust to the ambient light, or it can be manually adjusted in the
menu system
• Rotary control plus 2 independent buttons for easy menu navigation and user input
• An external output activates when a high alarm condition has been reached
• Wide input supply voltage range of 8 to 30V DC with built in voltage reversal and over voltage protection
for harsh electrical environments
• 1 year limited warranty
