ECU converter HORNET
Manual Version 1.1
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
60 mm
22 mm
12 mm

1Hardware
1.1 Description
Beeper, STATUS LED and function button work like the corresponding components on the
IO- BOARD (please refer to the manual of the HORNET ECU for details).
On the VSpeak ECU Converter STATUS LED and function button has additional functions
(see section 2.0 and 2.4.2).
The Micro SD card slot is used for updates.
The blue LED is blinking every second to signal the normal function of the ECU Converter.
1.2 Installation
The ECU Converter can be mounted inside the model with M3 nylon standoffs and screws or
something similar. The provided LED socket can be mounted in the hull in order to see the LED
from outside of the model.
1.3 Connection
The RJ12 Western plug has to be connected DIRECTLY to the "TERMINAL" socket on the
HORNET ECU. Since the ECU Converter replicates the function of the IO-BOARD and the
TERMINAL, you must not connect both at the same time. If you do so the ECU might show
abnormal behaviour.
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.

2Telemetry
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.
The telemetry of the ECU Converter can be used to switch between the systems Jeti Duplex
EX, HoTT and multiplex. The ECU Converter for spectrum comes with the special XBus
connector, so no switching for another telemetry system is possible here.
2.0 Selection of the telemetry system
When you turn on the Telemetry System is signaled by a LED for a period of 3 seconds. While
the blue LED flickers, the STATUS LED shows the chosen telemetry system:
green Jeti Duplex EX
red Multiplex
green (flickering) HoTT
Double-click on the function button (similar to the double click of a computer mouse), the
telemetry system can be switched. This is acknowledged by the signal generator with a short
sound (frequency up and down). At the same time, the LEDs indicate the newly recruited
telemetry system. To preserve safety during the selection of the telemetry system, the ECU
Converter does not transmit any information until a restart. The setting is saved.

2.1 Jeti Duplex EX
2.1.1 EX-data DC/DS-radio
The EX-Protocol is partially backwards compatible. On older non-EX devices you get only
Jetibox functions. On EX devices like the DC/DS radios and the Jeti "Profibox" you get
additional data.
(VSECU … VSpeak ECU Converter):
FUEL, F-FLOW, THRO not supported on HORNET II
On HORNETT II PUMP and BATT values are only
updated as long as these voltages are shown on
STATUS DISPLAY 1.
The EX-data IS ONLY UPDATED if the HORNET ECU is on STATUS DISPLAY 1 (after
switching on the radio this display is active).
2.1.2 Jetibox
On the Jetibox all data of the HORNET ECU normally displayed on the TERMINAL are shown
(except characters that cannot be displayed on Jeti Systems).
Furthermore you can use the Jeti-keys to edit all values available on the TERMINAL. Please
refer to the HORNET ECU's manual.
