20-6 SkyView System Installation Guide - Revision R

 DISCHARGING: SkyView system voltage is below 10V. SkyView runs on the SV-BAT-320. The

SV-BAT-320 discharges.

 CHARGED: SkyView system voltage is above 12.25V, and the SV-BAT-320 is fully charged.

 STANDBY: SkyView system voltage is above 10V, but below 12.25V: SkyView runs on master

power but does not charge the SV-BAT-320. To conserve your aircraft battery, the SV-BAT-

320 is only charged with SkyView detects your alternator/generator to be online.

 NO BATTERY: No SV-BAT-320 is connected.

Operational State of the Internal Voltages

There are several important voltages in the display. You will find their statuses here. If they are

all operating at specified levels, then you will see OK. If any voltage is operating out of

specification, you will see X.XV FAIL for that voltage.

Screen Brightness Level

The screen's brightness level is shown here as a percent. For example, 100.0 means 100% and

50.0 means 50%.

Local Light Sensor Output

Each SkyView display has an integrated light sensor on the front bezel and its output is shown

here.

External Light Control Signal Output

SkyView displays are compatible with external light control signals. The state of the external

light control signal is shown here.

Brightness Level Output

SkyView displays can output a brightness level signal to control the brightness of compatible

external equipment screens. The level of the output is shown here.

Contact Input Status

Each SkyView display has four contact inputs. The status of each contact input is shown here as

either HIGH or LOW. CONTACT INPUT 1 is implemented as EXTERNAL LEVEL button. CONTACT

INPUT 2, CONTACT INPUT 3, AND CONTACT INPUT 4 have not been implemented as of v11.0.

Serial Port Status and Current Baud Rate

Each SkyView display has five general purpose serial ports. The status of each serial port is

shown with transmit (TX) and receive (RX) character counters and the ports current baud rate.

The character counters show any outgoing or incoming character and roll over at 9999.
