FIVE PIN CONNECTOR:
• GROUND, NC, NC, POWER INPUT, BACKLIGHT DIMMER
SEVEN PIN CONNECTOR:
• GROUND, NC, NC, +5V REGULATED POWER OUTPUT, DNC x 3 (DO NOT CONNECT x 3)
•
WARNING: DO NOT ATTACH ANY EXTERNAL POWER INPUT TO THE +5V OUTPUT on the seven pin
connector. DOING SO WILL DAMAGE OR DESTROY YOUR UNIT.
SPECIFICATIONS
CONT.
INSTALLATION
Fits any standard 2.25” mounting hole.
Use only the screws provided. DO NOT DRILL OUT HOLES FOR
LARGER SCREWS. Doing so will void warranty!
Requires a voltage source between 10 and 36 volts.
Power draw is <100 milliamps (backlight full on).
Use with an external avionics power switch (not supplied).
Use with an external dimmer potentiometer (supplied with
unit).
INSTALLATION DETAILS
The rear main external electrical connector has five wires:
ground, none, power, and backlight input. A harness is sup-
plied with the unit. The ground must be connected to avionics (system) ground. The power must be con-
nected to a voltage source between 10 and 36 volts. The backlight input may be connected to a variable
voltage source, providing between 0 and 5 volts. Typically, this is supplied from the wiper of a potentiom-
eter (included.) If left unconnected, the display will be dim.
NOTE: DO NOT DRILL OUT THE CORNER HOLES. THIS WILL DAMAGE THE LCD MODULE AND VOID
YOUR WARRANTY!

mounting holes are on 2.625” diameter circle.
Inner circle is 2.25”.
APPLICATIONS
May be used to display turn rate and roll coordination information in experimental and ultralight aircraft;
also in LSA aircraft with manufacturer approval.
NON-TSO’d; non-PMA’d.
SWITCHES & INDICATORS
The main color LCD screen provides continuous graphic information to the pilot.
A tactile switch allows unit calibration.
FUNCTIONALITY
This gauge provides real time roll and yaw information. The yaw information is shown with an illustra-
tive airplane model and also in digital degrees per second format. Roll information is shown with a classic
bubble illustration.
The unit is calibrated so that a 2 minute turn will match the left or right deflection hash marks. This is
equivalent to a rate of 3.0 degrees per second.
