Jeti + iGyro News !!

  • Jeti news !!


    Jeti´s latest receiver software releases (> 3.22) are able to output the digital EX-protocol (16channels) or UDI-protocol (12 channels) additional to the normal channel outputs. With the use of the UDI protocol you are also able to use your complete telemetry.


    The new iGyro Software release V20 is able to decode both signal types.


    How to set the receiver to EX protocol:


    - Output mode: PPM Positive
    - No. of channels: 16 channels
    - Output mode: EX Bus
    - Output period: 14ms
    - Failsafe: Disabled


    Connect output EXT. of the receiver with BUS1 or BUS2 from the iGyro



    How to set the receiver to UDI protocol:


    - Output mode: UDI Bus
    - Output period: 14ms
    - Failsafe: Disabled


    Connect output SAT of the receiver with BUS1 or BUS2 from the iGyro. Telemetry sensors can be connected to EXT.


    A wiring diagram is shown here:

  • Good Morning,
    I have buy your iGyro SRS with GPS this Juli 204.


    I own a Jeti DC 16 (FW 3.00) + Central Box 200 with two Duplex Rsat 2x (FW3.22).


    I connected the two RSAT in outputs-pins RX1 and RX2 of the Central Box 200.


    I have set the TX: Double Path mode.


    I have set the receivers (RSAT1 and RSAT2):
    Output mode: Ex Bus & PPM Positive
    No. channels 16
    Output period: 14 ms
    Failsafe : disabled


    In your previous post you say: "connect ouput of the SAT receiver with BUS1 BUS2 or from the iGyro " but the outputs-pins SAT, in Central Box 200, is already occupied by RSAT 1 and RSAT2.


    Question: in which the output-pin of the Central Box 200 I have to connect iGyro?


    IGyro will be materially connected with the Central Box only through one (01) exit-output-pin. Through this exit-outpunt-pin will leave the controls for: elevator, aileron und rudder.


    Question: how do I program the TX so that through the only exit-output-pin to pass the commands to elevator, aileron und rudder?


    Sorry for the perhaps trivial questions and for my English!


    Thanks for the reply.

  • Hello,


    2 options with the Central Box :


    1. you can use only one R-SAT on Input RX1. RX2 must be programmed as output for the iGyro (PPM, UDI or EX output)
    2. You use a Y-harness. Set both Satellites to UDI or PPM. With a Y-Harness go from Satellite 1x to CentralBox and 1x to iGyro BUS input. Do the same with the second R-SAT

  • ...thanks.
    I connected the iGyro in pin RX2 of the Central Box.
    Question: how do I program the TX so that through the only exit-output-pin ( in this example: RX2) to pass the commands to elevator, aileron und rudder?
    Ciao.

  • Richard and Enry


    Enry originally posted this question in the RC Universe forum and I already gave him the advice to use a Y lead. I told him to post this question here also just to make sure that my idea was right.


    Richard, I understand that this is a support forum for your own products and you cannot know the settings and procedures of all the radio brands out there, so unfortunately I have to correct your statements a little. The Jeti Central box only works with the "EX Bus" protocol. So if it's ok to use a Y lead, then there is NO configuration required for the receiver, because every Jeti RX provides the EX bus protocol at the "EXT" labeled port. If there is no EXT port (the smaller RXs don't have that), the EX bus is usually available at the output pin with the highest number. In this case the iGyro must of course be set to "Jeti EX Bus" in the receiver setting but there is no further programming required for the receivers and also not for the Central Box.


    I also suggested Enry to use the UDI protocol, but since we don't have the RSat 2 here in the US, if cannot confirm if that'll work, because I don't know their features. Assuming the RSAT and the R3 receivers we are using here in the US are similar, it should be possible to have the UDI protocol on pin number 2 and the EX bus would be on pin 3 by default. In that case the Central Box inputs would be fed by the EX bus output of the receivers AND ADDITIONALLY there would be one wire coming from each receiver going to the SAT inputs of the iGyro. I also want to stress that this programming only affects the receivers and has nothing to do with the Central Box. Just open the "Model" menu of the Jeti transmitter and select "Device Explorer" sub-menu. You should find both receivers listed there. Click on the first receiver in the list and set the "Serial Link" option to "UDI". A hint "PPM OUT / UDI PIN number X" will appear telling you exactly which is the correct output to use for the UDI protocol. Exit this menu and repeat the procedure for the second receiver as well.


    Besides the programming, I also advised Enry already that the combination of the Central Box in combination with any external gyro does not make much sense from a safety standpoint. Why pay the extra money for the Central box but you still have to connect the most important servos to the gyro? This setup still gives you full receiver redundancy, but in case that one of these main servos fails, I am pretty sure the the power surge will affect the entire system. To my mind it would make much more sense to combine the iGyro with a Powerbox SRS to utilize all safety features, but this is of course up to Enry.


    Good luck!

  • I have the problem that control surfaces is jerk some time like every 30 secund. i had try diffrent settings in ms and also try auto in output period.
    know i use this settinge but still have the problem
    - Output mode: UDI Bus
    - Output period: 14ms
    - Failsafe: Disabled


    I have try to disconnect the Igyro and only use reciver. f I do like that the problem is solved. but i will like to use the Igyro SRS.

  • Hello,
    there are different options to check:
    - Is your satellites at latest release, some older versions are not constant framerate
    - Is the problem also with only 1 satellite
    - Set the Framerate in the satellite to 10ms, iGyro to 15ms

  • Salve,
    da die CB200 das UDI von Update V24 nicht versteht, es geht nur EX und PPM, wie ist der Status der Umsetzung des Ausgangs vom I-Gyor SRS im Jeti EX-Protokol, incl. Rückwärtsdurchlässigkeit für die Telemetriedaten?
    PPM ginge zur Not auch, dann kann man die CB-Box-Telemetrie mit nem Kabel von der CB zum Empfänger zurück speisen.


    Bavarian Demon ist mit dem neuen Cortex Pro schon so weit, dass das Jeti-Ex-Protokol durch den Gyro in Richtung CB funktioniert, am Rückkanal für die Telemetrie wird gerade gearbeitet.


    Ein I-Gyro vor der CB wäre deutlich besser als ein 3e hinter der CB.

  • Hallo,


    vorwärts und rückwärts das Protokoll von zwei Empfänger rein und raus ist technisch kaum umsetzbar. Ich muss dazu nur sagen: Einfach mal nachrechnen und als Denkanstoß:


    --------------------------------------------------------------------------------


    Variante A)
    - CB200
    - 2x R-Sat
    - Kreisel (egal welcher Hersteller)
    - Redundante Spannungsregler


    Preis?


    --------------------------------------------------------------------------------


    Variante B)


    - Mercury SRS
    - 2x R-Sat


    Kostet?


    --------------------------------------------------------------------------------


    Da muss man keine großen Rechnungen anstellen. Zumal die Mercury noch einiges an Funktionen und Einstellhilfen aufweißt die die CB200 nie haben wird. Nicht zu vernächlässigen die Fehlerquellen durch einen Haufen Kabel!
    Für uns völlig uninterssant einen 299€ Gyro (kostet das nicht auch der Mitbewerber?) mit aufwendigen Telemetrie Funktionen auszustatten wenn man für 399€ ein komplettes Gerät haben kann.

  • Richard,


    ich wollte diesen alten Thread nochmals kurz mit einer Warnung wiederbeleben. Die oben geschilderte Verdrahtung des iGyro SRS und einer Jeti Central Box ist so absolut nicht zu empfehlen und sogar gefährlich! Das Problem ist, dass sich der iGyro und alle daran angeschlossenen Servos den Strom über die beiden Y-Kabel holen, welche an die Empfänger Eingänge der Central Box angeschlossen sind. Diese sind jedoch nur mit 0,5 Ampere pro Buchse abgesichert. Vier Hochvolt Servos unter Belastung ziehen mehr als 1 Ampere an Strom und somit wäre im schlechtesten Fall der komplette Gyro und auch die daran angeschlossenen Servos Strom-los!


    Das Problem lässt sich aber leicht umgehen, indem man die Servo Kabel auftrennt und nur das einzelne Signal Kabel an den Gyro anschließt. Die Plus und Minus Leitung steckt man ganz normal in die Central Box. So fließt der Strom primär über die Central Box und die Last ist kein Problem mehr.


    Eventuell kannst Du ja die Zeichnung überarbeiten.


    Gruß
