ERES limiter
SW for competition flying

MVario2
ERES limiter is a special type of MVARIO2 firmware designed for the
competition category of electrically powered gliders (ERES).
Measurements and height calculations are the same as the
specifications of F5J category. Settings and telemetry are strictly
limited according to the needs of the ERES competition. This special
firmware can be uploaded via JETI Studio to the MVARIO2 sensor by
a USB adapter. The ESC-In port is the input port for connecting the
throttle channel from the receiver. The ESC-Out port is the output
port for connecting the controller.
Telemetry data of the sensor:
● Set switch-off height
● Set switch-off time
● Firmware version
Sensor settings:
● Motor shutdown pulse (default 1.1ms)
● Switch-off height setting (90m by default)
● Switch-off time setting (30s by default)
Data displayed by the sensor:
● Current sensor status (Initialization, Idle, Ready, Running,
Measuring, Done)
● Maximum measured relative height
● 10 relative height values

1 Description and function
EN

MVario2
The sensor can only be configured if the ECS-in throttle channel
(pulse) is not connected after connecting the power supply to the
sensor. Once a pulse is connected to the ESC-in, the sensor can no
longer be set until its power supply is reset. Settings can be made by
the Jetibox or DC/DS transmitter (in the "device explorer" menu).
The measured data can be seen if the sensor is in the "Idle" or
"Done" status. The sensor save the data from the last measurement
and can be read again after connecting the power supply. In the
Idle status, you can view the data from the last measurement.
Measurement data means the maximum relative height reached
during motor run and 10s after that and 10 relative altitude values
saved after 1s of motor run.
The sensor can be in the Ready status if a throttle control pulse is
connected to the ESC-in input and the pulse value is less than the
set level for motor shutdown (default setting 1.1ms).
The Sensor will be in the Running status if the throttle control pulse
exceeds the motor shutdown pulse level. After stopping the motor
the sensor goes from the Running status to the Measuring status
and the sensor evaluates the measurement for another 10s.

The motor is shutdown if:
● Set height is reached
● Set time is reached
● The throttle lever has been pulled below the set level
The motor will be stopped, whichever occurs first (terms above).
After stopping the motor, the motor cannot be restarted until the
sensor power is disconnected and connected again and the sensor
returns to the Ready status.
To calculate the height is used the sea level pressure
1013,25 hPa - ISA (International Standard Atmosphere)

Main settings.
Sensor display in status "Ready"
To display the ERES limiter in "device explorer", it is necessary to
have the configuration file ERES.bin in the Devices folder in the
transmitter. The sensor have to be connected to the EXT output
of the receiver and the output have to be set as EX BUS.

3 S ettings by the JETIBOX
The DC/DS transmitter in the "device explorer" menu or Jetibox
can be used to view 10 measured heights (measured after 1s).
After connecting the power supply (for 3 seconds) the
initialization screen with information about the ERES firmware
version marked "E" as ERES will be displayed on the Jetibox. This
time of 3s is also needed to initialize the relative height of the
sensor. Data cannot be read or set in the "Jetibox" emulator
application in the DC/DS transmitters.
Jetibox menu diagram:
Use the up and down arrows on the Jetibox to switch between
the individual screens. Use the left and right arrows to set up the
values.

measured as zero, they are not displayed.
The setting is only displayed until it is detected
