23.8.12 Serial Port Status and Current Baud Rate
Each SkyView display has five (5) 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.

23.9 Instructions for Continued Airworthiness
Follow these steps for continued airworthiness:
• Conduct any periodic checks that are mandated by local regulations (IE, FAA
for US Aircraft), such as (but not limited to):
o Transponder test
o Pitot / Static system test - refer to “Performing Pitot/Static Checks” near the
end of the SV-ADAHRS-200 Installation and Configuration section.
• Annually test the SV-BAT-320 Backup Battery.
• Annually perform a ZERO PRESSURE IAS/AOA CALIBRATION.
