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 EFIS.
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 EFIS
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.
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 aluminium, steel or even heavy ice,
the Ultra EFIS will not operate properly. Signals may also be blocked by heated wind screens
(fibreglass, plexiglas and other plastics are normally transparent to GPS signals). If you find
that the Ultra EFIS 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 EFIS from an 11V to 36V supply. Mount on the power wire
(RED) the 1A fuse holder, provided in the box, to protect against short circuits.
Serial Connection
The Ultra EFIS has serial RS232 connection ports to interface to an external device, used to
interface with a transponder.
The Ultra EFIS can be connected to a Micro Air T2000 transponder using the RS232 serial
connection shown on Figure 5.
