Introduction
The VSpeak ECU Converter for HORNET ECUs is emulating the IO-BOARD and the
TERMINAL. Data, which is shown on the STATUS DISPLAYs of the TERMINAL can be
sent via telemetry to the radio. To avoid unwanted electrical effects between the ECU and RC-
system the VSpeak ECU Converter is galvanically isolated via optocouplers.
The ECU Converter can interpret and transmit data from the HORNET III and older
HORNET II ECU.
The VSpeak ECU Converter can be software-updated by the user.
The current version has been tested with the following ECUs/Versions:
HORNET II V7.1B
HORNET III V2.5A
ECU Converter HORNET Version: 1.1

For Jeti Duplex, Multiplex (and ACT) and HoTT the VSpeak ECU Converter is shipped with an 3-pin connector to connect to the telemetry port of the RC system. For Spektrum systems the VSpeak ECU Converter is shipped with a 4-pin connector for the X-Bus port of the telemetry module. -
Page 4: Telemetry
2 Telemetry The voltage for the VSpeak ECU Converter is supplied by the HORNET ECU. As soon as you switch on the HORNET ECU and apply a valid signal to the throttle channel (either from the radio or a servo tester) you will get telemetry data. Otherwise no data is generated. -
