LOG SETUP MENU {TELEMETRY DISPLAY AND RECORDING OPTIONS
}
SYSTEM
The LOG SETUP menu allows you to turn Telemetry Recording ON and OFF and configure how Telemetry Data is displayed on
the TELEMETRY screen. For example, you are able to change the Telemetry Temperature reading from Fahrenheit to Celsius,
change the values at which the different Telemetry Sensor alarms sound, change how Speed and RPM are displayed and
much more.
In addition, when only the DISPLAY is turned ON using the DISPLAY key, the M12S can be placed in Receiver Mode, allowing it to
Bind with another Airtronics FH3 or FH4T transmitter and read Telemetry Data from it. For example, if using an FH4T transmitter
like the MT-4, MT-4 Telemetry Data can be viewed on the M12S TELEMETRY screen, or, if using an FH3 transmitter like the MX-3X
or M11X that doesn't support Telemetry, Steering and Throttle Output Data can still be viewed on the M12S TELEMETRY screen.
This capability allows the M12S to be used as a separate Telemetry Viewer and Recorder, much like the Airtronics TLS-01
Telemetry Logger.
For information about saving Telemetry Data to a PC, see the
TELEMETRY screen and viewing Telemetry Data, see the
PC
LINK
Menu
section on page 58. For information about using the
TELEMETRY Screen Overview
section on pages 21 ~ 22.
IMPORTANT: Full Telemetry integration requires the use of an Airtronics RX-461, RX-462 or other Airtronics FH4T Telemetry
receiver (available separately), although Throttle and Steering Output Data can still be viewed on the TELEMETRY screen and
recorded if using an FH2, FH3 or FH4 receiver.
For information about using an optional Telemetry receiver with your M12S transmitter, plugging the Telemetry Sensors into
your receiver and installing them into your Model, see the
Telemetry Data Recording
Telemetry Connections and Mounting

Calibrating the RPM Sensor - Changing the Ratio Value, Continued....
The Ratio value is the gear ratio between the two gears that the RPM sensor is mounted to. For example, if the RPM sensor is
mounted to your spur gear, the Ratio value will be the gear ratio of your spur gear and pinion gear.
IMPORTANT: To calculate the gear ratio, divide the number of teeth in the spur gear by the number of teeth in the pinion gear.
For example, if your spur gear is 60T and your pinion gear is 14T, the gear ratio is 60 / 14 = 4.28.
2) Press the ENTER key, then scroll UP or DOWN to choose the desired first Ratio
value. If using the example above, choose 4.
3) Press the ENTER key, then scroll DOWN to highlight the second Ratio
value. Press the ENTER key, then scroll UP or DOWN to choose the desired
second Ratio value. If using the example above, choose 28.
4) If necessary, press the ENTER key, then scroll DOWN to highlight the third
ratio value. Press the ENTER key, then scroll UP or DOWN to choose the
desired third Ratio value.
RATIO setting range is 1.000 to 64.999. The default setting is 1.000.
If the RPM sensor is mounted to your engine's flywheel or your motor's pinion gear to read the RPM directly, the Ratio value
should be set to 1.000.
Calibrating the RPM Sensor - Changing the 10Count Distance Value:
The 10Count Distance value can be changed if you've Selected UNIT > MPH or UNIT > KM/H. By changing the 10Count Distance
value you are able to calibrate the RPM sensor to read your specific Model's actual speed, in either MPH or KM/H.
Prior to calibrating the RPM sensor, you must connect the RPM sensor to your receiver and correctly install the RPM sensor
into your Model. For more information, see the
Telemetry Connections and Mounting
section on pages 96 ~ 97.
1) With your transmitter and receiver turned ON, and with an Active Telemetry connection, place your Model on the ground.
2) Measuring in inches (or centimeters if using KM/H) from where you set your Model on the ground, slowly push your Model
and measure the distance covered to complete 10 full revolutions of the RPM sensor (the Bind LED on your receiver will flash
10 times, indicating 10 full revolutions).
3) From within the RPM menu and with UNIT > MPH or UNIT > KM/H Selected,
scroll UP or DOWN to highlight 10COUNT DIST > 12.0 or 10COUNT DIST > 30,
depending on the UNIT > value Selected previously.
4) Press the ENTER key, then scroll UP or DOWN to change the 10Count Distance
value to match the measurement obtained in step 2 above. For example, if
your Model traveled 2 feet (61cm) to complete 10 full revolutions, enter 24.0
(for MPH) or 61 (for KM/H).
10COUNT DIST setting range is 0.5 to 118.0 for MPH and 1 to 300 for KM/H. The
default setting is 12.0 for MPH and 30 for KH/H.
IMPORTANT: Changing the 10Count Distance value will change the Maximum Scale value. After calibration, you should reset
the Maximum Scale value back to the value you chose previously.

menu.
2) Press the ENTER key to open the LOG SETUP menu, then scroll UP or DOWN
to highlight the VOLT menu.
3) Press the ENTER key to open the VOLT menu. MAX VOLT > 9.0V will be
highlighted.
4) Press the ENTER key, then scroll UP or DOWN to choose the desired Maximum
Voltage value. This value determines the Maximum Voltage that will be
displayed on the TELEMETRY screen VOLT page and also calibrates the VOLT
Indicator on the TELEMETRY screen ALL page. We suggest using a value that
matches as closely as possible the peaked voltage value of your receiver
battery after it's pulled off your charger.
MAX VOLT setting range is 3.0V to 9.0V. The default setting is 9.0V.
The Maximum Voltage value cannot be set Lower than the Alert Voltage value. If necessary, you may need to Lower the Alert
Voltage value prior to lowering the Maximum Voltage value.
Changing the Alert Voltage Value:
The Alert Voltage value determines the voltage at which the receiver battery Low Voltage Alert alarm will sound. For example, you
can set the Alert Voltage value to alert you to when your Model's receiver battery is getting low and needs to be recharged. When
the Alert Voltage value is reached, the Voltage Alert alarm will sound and LED2 will flash. The Low Voltage Alert alarm will sound
for approximately 5 seconds, however, LED2 will continue to flash until you recharge the receiver battery. The audible portion of
the Low Voltage Alert alarm can be cleared by pressing the BACK or ENTER keys.
1) From within the VOLT menu, scroll UP or DOWN to highlight ALERT VOLT > 3.8V.
2) Press the ENTER key, then scroll UP or DOWN to change the Alert Voltage
value. The Alert Voltage value is the voltage that the receiver battery Low
Voltage Alert alarm will sound at.
ALERT VOLT setting range is 3.0V to 9.0V. The default setting is 3.8V.
IMPORTANT: Refer to the manufacturer of your Model's receiver battery to determine the safest Alert Voltage value to use. In
general, the Alert Voltage value should be high enough to alert you when it's time to recharge your receiver battery, but not so
low that the receiver can no longer control your Model or operate your servos optimally.
The Alert Voltage value cannot be set Higher than the Maximum Voltage value. If necessary, you may need to raise the
Maximum Voltage value prior to raising the Alert Voltage value.
