6.1 Markings
7 Equipment Limitations
7.1 Installation
7.1.1 Modifications and Use Outside of Intended Scope
This device has been designed and tested to conform to all applicable
standards in the original form and when configured with the components
shipped with the device. It is not permissible to modify the device, use the
device for any use outside of the intended scope, or use the device with
any antenna other than the one shipped with the device.
7.1.2 Deviations
Output power is limited to 20W.

8 Equipment Installation
This section describes the installation of ping20Si and related accessories
in the aircraft, including mounting, wiring, and connections.
8.1 Unpacking and Inspecting
Carefully unpack the device and make a visual inspection of the unit for
evidence of any damage incurred during shipment. If the unit is damaged,
notify the shipping company to file a claim for the damage. To justify your
claim, save the original shipping container and all packing materials.
8.2 Mounting
The ping20Si is designed to be mounted in any convenient location in the
cockpit, the cabin, or an avionics bay.
The following installation procedure should be followed, remembering to
allow adequate space for installation of cables and connectors.
• Select a position in the aircraft that is not too close to any high
external heat source. The ping20Si is not a significant heat source
itself and does not need to be kept away from other devices for this
reason.
• Avoid sharp bends and placing the cables too near to the aircraft
control cables.
• Secure the transponder to the aircraft via the supplied mounting tape.
It should be mounted on a flat surface.

UAV-1001626-001 Rev F
ECCN 7A994 Page 14 | 30
8.3 Connections
Whenever power is supplied to the transponder, a 50ohm load
must be provided to the SMA connection. You can use the
supplied antenna or a commercially available 50ohm load.

8.5 Cooling Requirements
ping20Si is designed to meet all applicable TSO requirements without
forced-air cooling.
Attention should, however, be given to the incorporation of cooling
provisions to limit the maximum operating temperature if ping20Si is
installed in close proximity to other Avionics. The reliability of equipment
operating in close proximity in an avionics bay can be degraded if adequate
cooling is not provided.
8.6 Antenna Installation
The following considerations should be taken into account when siting the
antenna.
• The antenna should be mounted in a vertical position when the
aircraft is in level flight.
• Where practical, plan the antenna location to keep the cable lengths
as short as possible and avoid sharp bends in the cable to minimize
the VSWR.
Electrical connection to the antenna should be protected to avoid loss of
efficiency due to exposure to liquids and moisture. All Antenna feeders
shall be installed in such a way that a minimum of RF energy is radiated
inside the aircraft.

ECCN 7A994 Page 18 | 30
9 Programming
These settings are stored in the ping20Si. To change these settings, the
ping20Si is configured via the supplied pingUSB Wi-Fi adapter and mobile
device application.

Configuration Items List
9.1 Default Control
Select the desired control type. This setting configures the ping20Si for
Standby, On or Altitude reporting.
• Standby/Off: Disables both the transmit and receive functions.
• ON: Responds to all interrogations and transmits ADS-B Extended
Squitter messages. Reports 0000 to altitude (Mode C) interrogations.
ALT: Responds to all interrogations and transmits ADS-B Extended
Squitter messages. Reports barometric altitude to Mode C
interrogations.
9.2 ICAO Number
The ICAO address is a 24-bit number issued to the aircraft by the
registration authority of the aircraft. These addresses are usually written as
a 6-digit hexadecimal number, although you may also encounter one
written as an 8-digit octal number. The echoUAT understands the

UAV-1001626-001 Rev F
ECCN 7A994 Page 20 | 30
hexadecimal format, so you must first convert an octal number to
hexadecimal before entering.
Tip: By using the N-Number Look Up function on https://www.faa.gov,
locate and use the “Mode S Code (base 16 / hex)” value.
9.3 Callsign
The CALL SIGN can be up to an 8 digit code that corresponds to the tail
number of the aircraft. (0-9, A-F).
Note: This is typically your aircraft N-number, unless otherwise advised by
the FAA or ATC.
9.4 Aircraft Category
To assist ATC tracking of aircraft, an aircraft category can be transmitted.
9.5 VFR Squawk Code
VFR squawk (Mode 3/A) code is a pre-programmed default code when the
pilot is flying VFR and not in contact with ATC. In the USA, the VFR
squawk code is 1200 and in most parts of Europe the VFR squawk code is
7000.
9.6 Aircraft Maximum Speed
Mode S transponders can transmit their maximum airspeed characteristics
to aircraft equipped with TCAS. This information is used to identify threats
and to plan avoiding action by the TCAS equipped aircraft. The airspeeds
are grouped in ranges.
9.7 ADS-B RX Capability
The ADS-B transmissions include an indication to the ground stations of
whether the aircraft includes a 1090MHz ADS-B receiver, a UAT ADS-B
receiver, or both.
