User’s Manual Altimeter Sensor Alti-DX2
January 2020
The Alti-DX2 is an altimeter sensor for Spektrum telemetry
receivers with X-BUS port or the Spektrum telemetry module
TM 000.
Alti-DX2 measures the current altitude above ground level.
The Alti-DX2 is designed specifically for model aircrafts, where
smallest dimensions, very low weight and simple handling is
required.
It is equipped with a barometric sensor and a 32-bit processor
and therefore has an excellent sensitivity and a fast response
time.
Alti-DX2 is connected directly to a Spektrum telemetry receiver
or the Spektrum telemetry module TM 000. No separate power
supply is required.

1. Installation
Alti-DX2 is connected to the X-BUS port of a Spektrum telemetry
receiver or the Spektrum telemetry module TM 000 via the
cable supplied.
After power on the receiver, the Alti-DX2 calibrates to the
surrounding air pressure and transmits an altitude of zero
meters. If the sensor is moved up or down, the measured
altitude 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 steps show how to setup the Spektrum DX6 G2/G3
transmitter (software version 2.05).
The setting process for other transmitters, receivers and
soft are versions may differ slightly from the procedure
described here. The description is therefore only for guidance:
. Power off the transmitter
2. Connect Alti-DX2 to the "X-BUS" port and if the TM 000 is
used connect the "DATA" port to the "DAT" port of the
receiver.

3. Press and hold the "BND" button on the TM 000 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 with the scroll wheel pressed.
Select "Bind" in the "System Setups" menu (Fig. 3).

5. In the “Bind” menu click “Bind” (Fig. 4)

6. The binding process was successful when both the receiver
(DSMX 22ms) and "Telemetry" were recognized (Fig. 5).

detected
7. Press the scroll wheel to access the "Function List" and
select "Telemetry" (Fig. 6).

8. To integrate Alti-DX2 the “Auto Configuration” function
must be used:
a. Power on the transmitter, then power on the receiver
b. Delete all Altitude and Vario sensors in the telemetry
menu
c. Select Telemetry >> Settings >> Auto-Config in the
Function List (Fig. 7)

9. Click on "Altitude" at position “4” and if required adjust the
alarms.
2. Installation in the model aircraft
Since the altitude is determined by measuring the surrounding
air pressure, the installation location should be as free from
drafts as possible. Rapidly moving air over surfaces can create
pressure differences that lead to deviating measurement results.
For this reason, altimeters should never be installed outside the
model aircraft. The optimal installation location is usually
protected from wind within the fuselage of your model aircraft.
Use double-sided adhesive tape or servo tape on the back of the
Alti-DX2 for fastening.
The Alti-DX2 measures air pressure. Therefore, do not wrap the
Alti-DX2 in air-impermeable plastic film.
