User Manual

A1 and A2 are the 2 analog ports available on D8R receivers. X8R receivers only have A1, which
measures the receiver's power supply. Range sets the maximum measurable voltage, i.e. 3.3V / (divider
ratio). For example with the receivers' internal sensor (1:4), this would be 13.2V. For the FBVS-01
sensor with the default ratio of 1:6, this would be 19.8V. The number next to "Ax channel" will show the
currently measured value, and can be used to confirm or correct the Range setting by comparing the
reading with an external voltmeter. Offset and custom units (A, m/s, m, °, %...) can be used in addition
to help scaling the input to accomodate 3rd-party analog sensors.
"Low" and "Critical" alarms for A1, A2 and RSSI will trigger audio warnings when the measured value
goes below the defined levels. When a microSD card with a Taranis voice pack loaded is present in the
slot, those alarms will be announced in clear voice (e.g. "A1 Low", "A2 Critical", "RF signal Low"). If no
card is present each will trigger a different beep pattern. We do recommend the use of the voice
capability as 6 different beeps can be difficult to remember under stress.
Blades: Number of blades for the RPM sensor.
Voltage/current: Allows choosing the input for the power calculation and mAh count features. These
should match the input you've connected the corresponding sensors to.
Variometer source: sensor type that is installed in your model. "Vario" is for the new FrSky vario sensors
as well as the openxvario (vertical speed is calculated by the sensor and transmitted digitally), A1/A2
are for analog sensors that transmit vertical speed as a voltage connected to the respective input. Limit
sets respectively the maximum expected sink rate, low and high dead band (no sound), and maximum
climb rate for the sounds generated by the Vario custom function. The low dead band can be set to
OFF, which disables sink tones altogether.
Following those basic parameters are the selection lists for the 3 custom telemetry screens that can be seen by
LONG pressing the PAGE key on the main views. Each screen can either show numerical parameters (9 in the
main screen area and 3 in the bottom bar), or 4 bargraphs with configurable upper/lower limits.
