SV-XPNDR-261/262 Installation, Configuration, and Testing
11-16 SkyView System Installation Guide - Revision S
SkyView’s own ADAHRS-generated pressure altitude. However, the altitude displayed by
SkyView on the PFD page is ALWAYS sourced from SkyView ADAHRS data.
To have SkyView use an external altitude serial encoder as the pressure altitude source for the
SV-XPNDR-261/262:
1. Wire a SkyView serial receive line to the respective serial transmit connection from the
serial altitude encoder. If your SkyView system has multiple displays, this connection
must be made to all SkyView displays in parallel.
1. Ensure there is a shared ground between the SkyView display and the serial altitude
encoder.
2. Configure this serial port on each display under SETUP MENU > SYSTEM SETUP > SERIAL
PORT SETUP. The SERIAL IN device for this serial port should be set to ICARUS/GARMIN
ALTITUDE.
Transponder Settings
The aircraft tail number must be set in SETUP > SYSTEM SETUP > AIRCRAFT
INFORMATION > TAIL NUMBER prior to configuring the transponder.
The following settings need to be configured before testing and using the transponder. They
are all accessed under SETUP MENU > TRANSPONDER SETUP:

STATUS: Displays online/offline status, displays hardware, firmware, and software
versions of the transponder. If shown in YELLOW, a software update for the transponder is
available for the transponder from the SkyView display.

GPS DATA: Determines the source of GPS position updates for ADS-B Out:
Use of any of the DIRECT GPS-to-transponder position reporting methods below
require that the GPS that is connected to the transponder be TSO’d when used in
the US. Additionally, only specific models are supported via these connections.
Other counties may have different regulatory requirements for GPS position
indicators that are connected directly to the SV-XPNDR-261/262’s direct serial
input.
o DIRECT (AVIATION): Generic GPS outputting Aviation format data, connected
directly to SV-XPNDR-261/262 pin 3, transmitting at 9600 baud. Using this setting
causes the transponder to transmit the following ADS-B performance parameters:
 SIL: 0 (Unknown integrity)
NACp: 0 (Unknown position accuracy)
NIC: 0 (Unknown containment)
NACv: 1 (10m/s accuracy)
As this data format does not contain all of the information that ADS-B position
inputs require, Dynon Avionics does not recommend using this type of GPS and this
setting; there is no advantage in doing so from using the SKYVIEW setting (below).
