Screen:
Excellent visibility.
A high strength protective glass is finely bonded to the LCD to eliminate any air bubble
between the cover glass and the LCD itself, reducing incredibly the internal and external
reflections. This allows to increase the contrast and visibility, in addition to providing greater
resistance to vibrations and eliminate any water condensation.
Thanks to this technology together with a powerful LED lighting it is possible to obtain a
visible display under different lighting conditions.
Benefits:
Reducing of light reflections
Contrast increased
Resistance increased
No condensation
Greater temperature range
Reducing parallax effect
Greater thinness

– Black Negative power (External Power GND)
–Yellow Plotter Serial Data TX_A (Serial port
A)
– White Plotter Serial Data RX_A (Serial port
A)
–Green GND (signal ground)

pag 15
3. Installation –Power Connection
To connect the ASTRA ESA D7 to the
boat’s power you have to connect the
following wires from the cable 10 of
ESA D7 wires :
– Red Positive power (External Positive power
10-35V DC)
– Black Negative power (External Power
GND)
– To lengthen the cables use AWG 18
–Use a fuse of 3A

pag 16
3. Installation –Power Connection
