Introduction

The VSpeak ECU Converter provides the data of the JetCat ECU on the telemetry system of your remote control system.

In the systems Jeti Duplex and Graupner HoTT the VSpeak ECU converter replaces the JetCat GSU (Ground Support Unit) completely, that means not only the indicators of the GSU are displayed on the transmitter - also most entries can be made conveniently via the transmitter.

To avoid unwanted electrical effects between the ECU and RC-system the VSpeak ECU Converter is galvanically isolated. The VSpeak ECU Converter can be software-updated by the user

Supported are:

The blue LED is blinking every second to signal the normal function of the ECU Converter. The Micro SD card slot is used for updates. The attachment of the VSpeak ECU converter in the model can be done with velcro tape, double

sided tape or cable ties.

1.1 Connection Telemetry port

With the servo patch cable included in the delivery, the Telemetry port of the VSpeak ECU converter is connected to the telemetry input of the respective receiver.

1.2 Connection Data port

With the Western patch cable included in the delivery, the Data port of the VSpeak ECU converter is connected with the JetCat ECU or I/O board. The VSpeak ECU Converter can be connected wherever the JetCat GSU is connected. With the help of a Y-connector (eg from reichelt.de, see chapter 4), a "parallel operation" of JetCat GSU and VSpeak converter is also possible.

VSpeak V1 . 0

The voltage for the VSpeak ECU Converter is supplied by the JetCat ECU. As soon as you switch on the JetCat 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

2.0 Select Telemetry System / Global Parameters

The telemetry system can be adjusted by using the Programming adapter (s. section Accessories) and the JetCat GSU. If ECU converter, GSU, receiver- or turbine battery are plugged into the programming adapter, the version of the ECU converter appears after a short initialization, followed by the display of the currently set remote control system. The navigation takes place in the usual way, ie "scroll" between the parameters with the +/- buttons - Value change with the pushed "Change Value / Item" button and added +/buttons, then instead of the ":" a small arrow shows the changed values.

With Jeti and HoTT, all other settings can be made directly from the transmitter. For all other remote control systems further specific settings can be made (follow the respective section). With the "Limits" button you can switch to the "Global" parameters (see next page). Press the button "Select Menu" returns to the "Telemetry System Selection". When the "Info" button is pressed, the version of the ECU converter appears.

All other keys of the GSU ("Min / Max" "Run" "Manual" "Set" "Spool") have no function for the VSpeak ECU converter.

Low A i rspeed : OFF kmh

H i gh A i rspeed : OFF kmh

Low Fue l : 800 m l

If ECU converter, GSU and a (2-3 cell LiPo / LiFe) battery are connected to the Programming adapter, the "Limits" button is used to set global parameters which are the same for all remote control systems:

OFF, 10 . . . 2500 ml Set: 800 ml

5.0 . . . 12.0 V Set: 5.0 V

OFF, 20.000 . . . 99.900 rpm Set: OFF

100 . . . 990°C Set: 800°C

OFF, 1.000 . . . 99.900 rpm Set: OFF

OFF, 10 . . . 150 kmh Set: OFF

OFF, 80 . . . 990 kmh Set: OFF

The parameters are largely self-explanatory, lower values as "Low" thresholds and exceeding of the "High" thresholds trigger alarms, with "OFF" the respective alarm is deactivated.

The "Low ..." alarms are activated after at first exceeding the "Low ..." alarm threshold. The low RPM (and RPM2) alarm ends at PUMP = 0.00V, which means that the speed alarm is suitable for signaling a "turbine flameout".

"Set" are the values set at delivery.

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):

Press the "left" key (= "Select Menu") and additional pressing the "right" (= "Change Value / Item") will take you to the settings of the ECU converter (see section 2.1.2.5).

2.1.2 Jetibox

On the Jetibox all data of the JetCat ECU normally displayed on the JetCat GSU are shown (except characters that cannot be displayed on Jeti Systems).

Furthermore you can use the Jeti-keys to edit most values available on the JetCat GSU. Please refer to the JetCat manual.

Alarms

Irrespective of the possibility to program alarm thresholds for the "EX" values in Jeti transmitters the VSpeak ECU Converter has the ability to set alarms (by using alarm codes) that are ECU status depending. These alarms can also be announced by the Profibox as voice messages. As can be seen in the table, the alarms for FUEL, RPM, RPM2, LoSpeed and HiSpeed can be switched OFF, if no alarm is to be given at BATT and EGT, the alarm thresholds can be set to "inaccessible" values. Permanently pending alarms, e.g. FUEL or BATT, max. 3 times repeated.

 FUEL

The alarm Fuel is signaled when the fuel rest is lower than the FUEL set value.

 BATT

The alarm BATT is signaled when the battery voltage is lower than the BATT set value.

 RPM (turbine)

The alarm RPM is signaled when the turbine rotation speed is lower than the RPM threshold value. The speed monitoring is started after at first exceeding RPM alarm threshold and ends with PUMP = 0.00V. The RPM alarm is suitable for signaling a "turbine flameout".

 EGT

The alarm EGT is signaled if the temperature exceeds the value set at EGT.

 RPM2 (2nd Shaft)

The alarm RPM2 is signaled when the 2nd Shaft rotation speed is lower than the RPM2 threshold value. The speed monitoring is started after at first exceeding RPM2 alarm threshold and ends with PUMP = 0.00V.

 LoSpeed

The alarm LoSpeed is signaled when the true airspeed is lower than the LoSpeed threshold value. The speed monitoring is started after at first exceeding LoSpeed alarm threshold.

 HiSpeed

The alarm HiSpeed is signaled if the true airspeed exceeds the value set at HiSpeed.

Jeti EX sensor name

In a 2-turbine model 2 VSpeak ECU converter can be used on Jeti Systems via an expander or CentralBox. The EX names are:

"1LECU" for Left turbine ECU on input 1 and "2RECU" for Right turbine ECU at the expander input 2.

2.1.3 Profibox - autonomous telemetry system for JetCat-ECU

Using a Jeti Profibox incl. RSat receiver and the VSpeak ECU converter the telemetry data from a JetCat ECU can be transferred completely self-sufficient to the pilot. Not only the settings using the Profibox can be made, as was shown in the previous chapters - all EX-data and the important alarms are displayed: EGT, FUEL, ECU battery voltage . . . are given as voice messages again.
