SV-XPNDR-261/262 Installation and Configuration
SkyView System Installation Guide - Revision AA 11-39
1. Check SETUP MENU > TRANSPONDER SETUP. The line GPS DATA should read
GPS DATA (OK) DIRECT (GARMIN ADS-B/ADS-B+)
2. On the Garmin GNS, GTN or similar IFR GPS, select the serial port connected to the SV-
XPNDR-261/262, and change the data format from “ADS-B OUT” to “ADS-B+ OUT”.
If your SV-XPNDR-261/262 has not been previously updated (such as if you are
updating to SkyView Software v12.2 from a SkyView Software version that is earlier
than v5.0, applying the SV-XPNDR-261/262 version 2.06 update will update your SV-
XPNDR-261/262 to the latest Software (it is not necessary to apply version 2.02, and
then version 2.04).
SV-XPNDR-261/262 Software Version (SW) v2.02/v2.04/v2.06 Labeling Requirements
(US Registered / Operated Aircraft Only)
This section applies to aircraft operated or registered in the US only.
In the US, updating your SV-XPNDR-261/262 Software from a SW version earlier than v2.02
REQUIRES that the physical transponder module be labeled to indicate the new TSO
authorization. Failure to perform this physical modification at the same time as the Software
update will result in a transponder that is not considered airworthy by the FAA. If your SV-
XPNDR-261/262 shipped with v2.02 (or higher), it will already have the correct label.
Applicability/Compliance
If your SV-XPNDR-261/262 shipped from Dynon Avionics after September 2012, it likely shipped
with Software version 2.02 (or higher) and is already labeled with its TSO C166b appropriately.
However, this is not authoritative.
To determine whether your SV-XPNDR-261/262 has an optional Software update available for
it, which will require that it be labeled should you choose to update it:
1. Go to SETUP MENU > TRANSPONDER SETUP > (right click). If the STATUS line is yellow,
there is a Software update available for your SV-XPNDR-261/262.
2. Examine the STATUS line. Example:
ON LINE HW 22.03 FW 01.02 SW 02.02
The Software version of the SV-XPNDR-261/262 follows the SW; in the example above
the Software version is 2.02 (and thus, will be highlighted in yellow).
3. If STATUS is highlighted in yellow, and the version is earlier than 2.02, and you choose to
update your SV-XPNDR-261/262, the new TSO authorization label must be applied
concurrent with updating the Software. Go to
www.dynonavionics.com/transponder (PDF)
which provides a new TSO authorization label that you can print out, cut out, and apply
to your SV-XPNDR-261/262.
4. Only after you have the label available, go to
SETUP MENU > TRANSPONDER SETUP > STATUS, press the LOAD button
and follow the instructions to update the Software.
