Audio and Video
Nesis can be connected to the audio system (audio out) and video (video in).
These two have nothing in common – audio and video are not associated.
Audio connection is used to allow Nesis to send out some audio messages,
mostly warnings, which can be then heard in the headset. Video is used to
show some video image from an on-board camera on the Nesis screen.
6.1
Audio Connection
Nesis is equipped with an audio output. Audio output is used to play audible
messages and warnings to the pilot.
Basic Nesis kit is shipped with an audio connector cable. One end of the cable
has a male 3
.
5 mm mono audio jack which fits into Nesis master unit. The
other end is open ended and it should be connected to audio panel or external
input of a radio station.
Audio output from the Nesis is 1
.
5 V@600 Ω peak-to-peak. Output is isolated
with an audio transformer, so both signal and ground must be connected. Use
of shielded cable for connection is preferred.
We provide short manual and schematic for most widely used radio stations.
