Variometer Sensor
Vario-DX
January 2020
The
Vario-DX
is a vertical speed sensor for Spektrum telemetry
receivers with X-BUS port or the Spektrum telemetry module
TM1000.
A variometer is used in sailplanes and indicates the rate of ascent
and descent via an audible tone. By this the pilot knows when
the sailplane is in a thermal of rising or sinking air.
An integrated altimeter provides information about the current
altitude above ground level.
The
Vario-DX
is designed specifically for model aircrafts, where
smallest dimensions, very low weight and simple handling is
required.
It is equipped with two barometric sensors and a 32-bit
processor and therefore has an excellent sensitivity and a fast
response time.
Vario-DX
is connected directly to a Spektrum telemetry receiver
or the Spektrum telemetry module TM1000. No separate power
supply is required.

Installation
Vario-DX
is connected to the X-BUS port of a Spektrum
telemetry receiver or the Spektrum telemetry module TM1000
via the cable supplied.
After power on the receiver, the
Vario-DX
calibrates to the
surrounding air pressure and transmits an altitude of zero
meters. If the sensor is moved up or down, the measured
altitude and the vertical speed is transmitted to the transmitter
via the telemetry system.
The height can be displayed in feet or meters. The corresponding
setting must be made on the transmitter.
The following pictures show how to setup the Spektrum DX6
G2/G3 transmitter (software version 2.05).
The setting process for other transmitters, receivers and
software versions may differ slightly from the procedure
described here.
The description is therefore only for guidance:
1.
Power off the transmitter
2.
Connect
Vario-DX
to the "X-BUS" port and if the TM1000 is
used connect the "DATA" port to the "DAT" port of the
receiver.

Press and hold the "BND" button on the TM1000 while the
receiver is connected to the power supply. The LED of the
receiver starts flashing and is waiting for the "bind" signal
from the transmitter.
4.
Switch on the transmitter for with the scroll wheel pressed.
Select "Bind" in the "System Setups" menu (Fig. 3).
