Updates (transmitters, receivers, controllers), JETI Studio

 

JETI Studio

JETI Studio is an advanced software tool for the Duplex system, available for free download from the manufacturer’s website. Select the correct version for your computer and install the program.

Main functions of the software include:
• Updating Duplex DC/DS transmitters
• Backing up transmitter data, models, and configuration
• Updating receivers, speed controllers, and other Duplex devices
• Graphical display of telemetry logs from the transmitter, analysis of measured values, and event reconstruction
• Real-time telemetry monitoring during flight
• Configuration of devices that support the EX Bus protocol

 

 

 

Transmitter Update and Data Backup

• Open the JETI Studio program and connect your transmitter to the PC using the supplied USB cable
• On the transmitter, press the F5 button under the screen to confirm “Connect to PC”
• In the JETI Studio menu, go to Tools > Transmitter Wizard and launch the Transmitter Update wizard, then follow the step-by-step instructions
• After the process completes, disconnect the transmitter from the PC, turn it off, and then back on to allow the installation of the new files

 

Tip: During the update process, you can initiate a backup of your transmitter data. The complete transmitter settings and stored models will be saved in JETI Studio. This allows you to revert the transmitter to a previous state as of the backup date. Since model configurations are included in the backup, it’s recommended to perform a backup after setting up and fine-tuning each new model.

 

 

 

Updating Receivers and Telemetry Sensors

To update Duplex system receivers and telemetry sensors, you need the JETI Studio program installed and the USB Adapter device. The USB Adapter connects devices to the computer’s USB port.

 

• Launch the JETI Studio program and go to Tools > Device Update
• Plug the USB Adapter into a free USB port on your computer (a green LED will light up on the adapter)
• Select the correct COM port from the list. Successful selection is indicated by a blinking red LED on the USB Adapter (signaling communication)

• Connect the USB Adapter to the Ext. port of the device you wish to update
• The connected device type and firmware version will appear in the upper window of JETI Studio
• In the lower right window, all available firmware versions will be listed. Select the appropriate version (usually the latest) and click Update to begin

 

Note: In the lower right window, a changelog describes what’s new or changed in the selected firmware version compared to the previous one.

 

 

 

 

Updating MEZON EVO and Newer ESCs

Warning: ESCs from the Spin, Advance, and JES series do not support firmware updates.
Warning: During the update, do not connect the black connector cable from the ESC to any device.

• Start the JETI Studio program and go to Tools > Device Updater
• Plug the USB Adapter into an available USB port on your PC (a green LED will light up)
• Select the correct COM port from the list. The correct choice is indicated by a blinking red LED on the USB Adapter (communication in progress)
• Connect the three-wire cable with red JR connector from the ESC to the USB Adapter
• For OPTO-type ESCs and all MEZON EVO / MEZON PRO controllers, connect a main power supply battery (For ESCs with BEC/SBEC, turn on their switch)
• The connected ESC and its current firmware version will appear in the upper window of JETI Studio
• In the lower right window, all available firmware versions for the device will be listed. Choose the appropriate version (usually the newest one) and click Update to begin

 

 

 

Updating Central Boxes

Update Central Boxes using the same procedure as OPTO-type ESCs. This means that after connecting the Central Box to the USB Adapter, you must also supply power to at least one of the main BATT inputs on the Central Box.

 

 

 

 

JETI Studio

JETI Studio is a free PC software for viewing telemetry data, updating, and configuring Duplex system devices. It is available for download at www.jetimodel.cz.

Main features of the program:

• Display of telemetry flight logs from the transmitter memory
• Backup and restore of transmitter configuration (see next page)
• Firmware updates for transmitters, receivers, ESCs, and telemetry sensors (see next page)

The ability to display telemetry data logs helps fine-tune model settings and verify correct installation of components. All Duplex system receivers provide basic telemetry data, such as signal strength on each antenna, signal quality, and receiver voltage. Additional telemetry depends on the sensors installed in the model.

Viewing telemetry logs in JETI Studio

• Install and run JETI Studio on your PC
• Connect your transmitter to the PC using a USB cable, turn it on, and confirm USB connection
• From the transmitter’s “Log” directory, select the desired model and specific flight. Logs are organized by “date/model name/flight time”
• Use “Menu / Add window” to create the number of display windows needed and choose how the data will be presented (graph, numeric, etc.)
• Drag and drop telemetry values from “Available telemetry” into each created window

 

Tip: You can display multiple values in a single window. For example, one graph can show current, ESC temperature, and battery voltage simultaneously.

 

 

Example of Displaying Selected Data

 

1. Display of available telemetry, connected sensors, and list of data that can be shown for the selected model
2. Flight time selector cursor
3. Playback controls – play, pause, and speed of replay for the selected flight
4. Graph showing signal quality (red) and signal strength on both receiver antennas (green and yellow)
   • Signal strength A1/A2: numerical values representing the strength of the signal received on each antenna of the receiver. These are approximate values that decrease non-linearly with distance.
   • Signal quality Q: indicates the success rate of bidirectional communication between the transmitter and receiver in percentage. The return signal from the receiver is always weaker than the transmitted signal from the transmitter. This means that even with a signal quality of “0”, the model remains controllable, only the telemetry data from the receiver is not received.
5. Numeric values measured by the ESC (current draw, battery voltage, consumed capacity, ESC temperature). Minimum and maximum values during the flight are shown on the right.
6. Display of current G-force
7. Artificial horizon showing model orientation in space
8. Complete flight path with current model position overlaid on a real-world map background. JETI Studio allows you to choose from various map types provided by Google or Microsoft. The flight path is color-coded to represent the model’s altitude.
