SV-XPNDR-261/262 Installation, Configuration, and Testing
11-20 SkyView System Installation Guide - Revision R
Note that after the transponder version 2.02 transponder update, only the SV-XPNDR-261 is
capable of meeting the 2020 ADS-B Out mandate, because of power transmission requirements
that the FAA ADS-B rules imposes. In other words, the SV-XPNDR-262, even if it is updated to
this software, cannot be used for 2020 ADS-B Out compliance credit.
SkyView v10.0 Transponder Software Version (SW) 2.04 Update
The optional transponder software (SW) version 2.04 software update that is contained within
SkyView software v10.0 and later fixes an issue that only pertains to some installations. It also
includes the updates described above for transponder firmware version 2.02 update. If either
of the following scenarios describes your installation, you should update your transponder to
version 2.04 software:
 If you have a Garmin GNS, GTN or similar IFR GPS that is directly connected to the
transponder to provide a certified position source via Garmin’s ADS-B format data output,
you MUST update to version 2.04 or later.
 If you are in the US and are using a Dynon transponder plus SV-ADSB-470 module to receive
both traffic and weather AND your transponder software version is a lower number than
2.02, you should update to version 2.04 to update so that it meets the latest TSO C166b. If
your transponder is not updated to the latest TSO, you will not receive a complete traffic
portrait. This applies whether or not you are using a TSO’d GPS or SkyView as your ADS-B
position source.
If your transponder has not been previously updated (such as if you are updating to SkyView
software v10.0 from a SkyView software version that is earlier than v5.0, applying the
transponder version 2.04 update will update your transponder to the latest software (it is not
necessary to apply version 2.02, and then version 2.04). If you are updating your transponder
for the first time, to version 2.04, the labeling requirements below apply.
Transponder Software Version (SW) v2.02/v2.04 Labeling Requirements
(US Registered / Operated Aircraft Only)
This section applies to aircraft operated or registered in the US only.
In the US, updating your transponder software to SW version (minimally) 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 updating from a version earlier than
v2.02 to v2.04, the label must be applied. If your transponder shipped with either v2.02 or
v2.04 it will already have the correct label.
Applicability/Compliance
If your transponder 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.
