Pitot-Static Connection
2 pin female connector on one side and unterminated solid lines on
the other. Red line connects to the 12 V DC avionics power bus and
blue line connects to the aircraft common ground. If you find power
cable too long, you can shorten it to any length, saving some precious
weight.
When you use more than one Emsis unit in the cockpit, other Emsis
units get power via CAN cable.
On our website you will find connection schema for Emsis unit with
or without UPSU unit.

Pitot-Static Connection
In most avionics installations there are several instruments that need
to be connected to the pitot-static system. A typical instrument
panel has at least a mechanical airspeed indicator and altimeter.
Emsis PFD unit shares the same pitot-static source with them.
Pitot-static consists of static pressure tubing and total pressure tub-
ing.
In order to connect to the static source, cut the static tube on an
appropriate place and insert plastic T junction. Cut some new tube
to length and connect T junction with the Emsis PFD static port.
We recommend use of hose clamps on all junctions and connections
to secure against slippage and to reduce chance of static pressure
leak.
Use the procedure above for the total pressure tube as well: cut the
total pressure tube, insert T junction, connect T junction and Emsis
total port and secure connections using hose clamps.
We strongly recommend labelling each tube before connecting to the
Emsis PFD or any other instrument. If you ever have to remove
Emsis PFD from the instrument panel, this will help a lot when you
will reinstall it.
