Support: ping20Si

A complete Mode S ADS-B transponder system with integrated SBAS GPS and barometric sensor, designed to meet conspicuity requirements for Unmanned Aircraft Systems (UAS) in controlled airspace.

Meets DO-181E Class 1, Level 2els (20W), DO-260B Class B1S, DO-229D Class Beta 1, ICAO Annex 10 Vol IV, and EuroCAE ED-115 Class LcF. Also complies with Radio Equipment Directive 2014/53/EU.

Use the provided double-sided mounting tape on the ping logo side and secure to a flat surface. Confirm cable lengths reach power before mounting.

The integrated GPS antenna requires a clear view of the sky. Avoid placement under props, near shadowing features, or under signal-blocking materials like carbon fiber.

Connect via the SMA connector hand tight (5-7 in/lbs). Mount vertically in a location least obstructed by the aircraft during flight.

50 × 25 × 17 mm, 20 grams.

11–28V DC (1W avg in ON/ALT, 0.5W in Standby). Use 11–16V DC during programming.

Pin 1: Power (11–28V)

Pin 2: Ground

Yes—connect the power harness to a 3S battery or appropriate aircraft power source.

1. Install uAvionix Ping App found under the “Utilities” header here.

2. Connect ping Programmer using JST ZHR-5 to 4-pin cable (5-pin to transponder, 4-pin to programmer).

3. Apply 11–16V DC.

4. Join Wi-Fi network Ping-XXXX (password: uavionix).

5. Launch app → Configuration → fill fields → Update.

SSID: Ping-XXXX (XXXX = random, e.g., Ping-5379) Password: uavionix “No Internet Connection” is normal.

It will not transmit while the ping Programmer is connected. Disconnect programmer and power after configuration.

Standby: No response to interrogation

ON: Replies with 4-digit squawk

ALT: Replies with altitude ADS-B 1090ES transmits only in ON/ALT with valid 6-digit ICAO.

Enter your 6-digit ICAO in hexadecimal. Convert from octal if needed. Do not enter 000000.

Call Sign: Tail number (A–Z, 0–9)

Emitter: Select UAV for unmanned

VFR Code: 1200 (U.S.), or your country’s default

Distance (in meters) from GPS antenna to:

Roll axis (lateral)

Nose (longitudinal)

No—but required to monitor latitude, longitude, and GPS altitude in the app. It is also required to transmit.

After “Device Configured”, tap Monitor and verify all fields. Tap OK, then disconnect power and programmer.

Control (JST ZHR-4, 57600 bps): GDL90/MAVLink (RXD, TXD, 5V, GND)

Programming (JST ZHR-5, 115200 bps): GDL90

Compatible with PixHawk TELEM and popular autopilots

No built-in receiver. Set ADS-B In Capability to None unless using a separate receiver.

Sets serial port baud rate for external control of the transponder.
