Page 3: Vario Benefits
A vario puts a whole new dimension into R/C sailplane flying. General Technical Features • The CS DataVario is an acoustic vario with altimeter and voice output. A sensor interface allows the implementation of external sensors like a current sensor (for electric flight), a temperature sensor or a GPS sensor. -
Page 4: Vario Acoustics And Voice Output
– the vario acoustics. Altitude changes of a few centimeters /second can be recognised by a tone change without considerable delay. The CS DataVario uses a well proven and often acclaimed analogue tone oscillator which has fully linear operation... -

characteristics without often uncomfortable frequency steps. Model sailkplane pilots who are familiar with varios in full scale planes confirm this. (By the way: CS stands for “ classic sound” !) Descent produces a continous tone which goes lower as the descent velocity is increasing. Climb (> 0 ft/sec is default setting) produces an interrupted, rising tone. -
Page 6: Altimeter Mode
Total Energy Compensation (TEK) The CS DataVario provides a port for the connection of a TEK probe, a feature which is borrowed from full scale aviation. In general, the probe is being attached to the fin. There are also probe versions which allow the installation on the rear fuselage (close behind the wings) on V-tail sailplanes. -
Page 7: Transmitter Settings
If there is no free servo channel available, the vario can be connected in parallel with any other servo. However, the pulse lead (yellow or white or orange colour) of the Y-cable leading to the vario has to be disconnected and a remote mode selection is not possible. The vario will remain in the altimeter mode. Transmitter settings Select the proper switch or slider and make sure that the servo travel is set to +/- 100% and the middle position at 0%. -
Page 8: Mode Setting Feedback
GPS module with a red LED: The GPS module becomes active as soon as the solid red changes to a blinking red. If the pitot tube sensor from SM-Modellbau is used (together with the WSTECH or the SM-Modellbau sensor interface), all above functions can be used without a GPS module, however, the readings will be “ airspeed”... -
Page 9: Glide Ratio Measurement And Announcement
Narrow circling should be avoided in order not to disturb the GPS contact. GPS Module Installation The GPS module can be connected to the vario either directly or via the WSTECH sensor interface. The antenna must have an unobstructed “ view” towards the sky and it cannot be used behind carbon fiber material. -
Page 10: Electric Drive Measurements
• temperature sensor from SM-Modellbau (optional) The CS DataVario offers important information about the electric drive to the pilot. The voice output of the drive measurements is independant from the other operating modes and does not interfere with them. The drive measurements are activated by selecting the appropriate code in Setup 9. -
Page 11: Selecting The Standby Mode
Selecting the altitude mode, coming from the integral mode (switch forward), and when using the pitot-tube-sensor either together with the UniLog A1 mode or the WSTECH sensor interface with the proper setting in Setup 10, option 3: single voice output of altitude and airspeed (km/h) 7.2.1... -

PCM-receivers). In such a case, the failsafe setting of the receiver channel controlling the vario is set at a servo travel of over 100 %. The CS DataVario will detect this pulse length and generate the voice output “ failsafe” . ( Refer to chapter 6.1) Flight Time or Motor Run Time (respectively) A flight timer can be activated in Setup 5, #2. -

Also, data conversion into other flight analysis software is possible. All evaluation information and software is available on www.wstech.de/user.htm Important: For a trouble free operation, only memeory cards offered by WSTECH should be used. 12 General Notes about Vario Operation The start-up sequence is as follows: •... -
Page 14: Important Notes About Sensor Interface Operation
UniLog, current sensor, temperature sensor and speed sensor are products from SM-Modellbau (www.SM-Modellbau.de) and are available in their online-shop. The UniLog data logger is connected to the vario with e special 3-lead cable from WSTECH. The 4-pole COM-port is used on the UniLog side. -

Alternatively there is the option of supplying the power from a direct connection to the R/C receiver. • CS DataVario Setup 14, current sensor type, is not active with the UniLog. The correct setting of the current sensor type has to be done directly in the UniLog. - Page 16 25% duty cycle, continous sink tone. #4 corresponds to #3, yet without sink tone.

If applicable the CS DataVoice may be updated to the latest software version with an USB Interface Cable (identical to the UniLog Interface Cable from SM-Modellbau, item # 2550). The latest software release and the update procedure is described on www.wstech.de/user.htm 20 Warranty There is a 2 year warranty starting with the delivery and referring to the functions of the product described in this manual. - Page 19 Range: approx. 2,000 m, depending on antenna position and with LPD at shoulder height Options with Sensor Interface from WSTECH or UniLog from SM-Modellbau Motor current measurement: up to 400 A, depending on current sensor type Voltage measurement: up to 60 V Climb rate measurement Temperature measurement: - 40 °C to 125°C...

Page 21: Instructions For Setting-Up The Uhf-Handy Lpd
The UHF-Handy is a general purpose walkie-talkie that can transmit and receive on two bands. In order to work with the WSTech Classic Sound 139-Channel Variometer it has to be setup to use the LPD band, use the same channel as the variometer has been set to, and squelch must be switched off. These settings only need to be made once, and can be done as below: 1. - Page 22 3. Select Band using the arrow keys, and select with the red key on the right . 4. Select LPD using the arrow keys, and select with the red key on the right. 5. Now use the arrow keys to choose the channel (1 to 69) and selected with the red key on the right. 6.
