AvMap Ultra EFIS
Connect the Pitot line to the port labeled PITOT and the static line to the port labeled STATIC.
Make sure the tubes fit tightly into the Ultra.
IMPORTANT : Use flexible plastic tubes with an inside diameter of 5 mm (0,2 inches).
IMPORTANT : We recommend to test the Pitot-static system for leakage after any
alteration.
External GPS receiver connection
Connect the external GPS receiver, included in the box, on the back side of the Ultra to the
GPS port as shown on Figure 5.
The GPS receiver comes with a 1,5 meter cable and is designed for use inside the aircraft.
Note: an additional gps extension cable of 2 meter is available.
The GPS receiver can be mounted to any convenient surface that has a clear view of the
sky. It can be mounted on the aircraft’s dashboard using the included Velcro strip. The GPS
receiver must have a clear view of the sky in order to receive satellite signals. GPS uses “line
of sight” signals to locate and track satellites.
If the signals are obstructed by dense objects such as aluminum, steel or even heavy ice,
the Ultra will not operate properly. Signals may also be blocked by heated wind screens
(fibreglass, plexiglass and other plastics are normally transparent to GPS signals). If you
find that the Ultra does not locate GPS FIX quickly or consistently, moving the location of the
GPS receiver a few inches often provides a better view of the sky.
Power supply
IMPORTANT : Power the Ultra from an 10 to 35 Vdc supply. Mount on the power wire
(RED) the 1A fuse holder, provided in the box, to protect against short circuits.
Serial Connection
The Ultra has serial RS232 connection ports to interface to an external device.
Note: current software 5.14 does not support serial in/out interface.
