Vista x 64
Vista x64 does not accept unauthorized kernel-mode drivers. To use AVR-CDC on 64bit
machine, you have to turn the "Driver Signature Enforcement" off by pressing the F8 function key
during system boot up.
"Driver Signature Enforcement Overrider" signs the driver as a Tested river and activates a test
mode so you can load it without a real Signature. You can find a more detailed description on the
download page of the override http://www.ngohq.com/home.php?page=dseo
USAGE
=====
To install the driver:
1. Download the "Driver Signature Enforcement Overrider".
http://www.ngohq.com/home.php?page=dseo
2. Start the DSEO (no installation is needed).
3. Choose "Sign a System File", click the "next" button and sign
lowcdc.inf.
4. Choose "Sign a System File" again, click the "next" button and sign
lowcdc.sys.
5. Choose "Enable Testmode" and click the "next" button.
6. Restart your computer.
5. The maintenance program of the altimeter
Before first use of the altimeter set its parameters. To do this, connect the altimeter to the
computer using a USB cable (as described above) and call the handler Altimetr.exe.
Then press the "Settings". "Setup" window appears.
You need to set the communication port number, which we checked with the driver installation. If
after you select the port you will receive an error message, then make sure you have selected the
correct port and that the cord is inserted into your computer and you have installed the USB driver.
Then, in the following order, input:
- Measuring altitude start
- Current temperature
- Select the frequency of measurements
- Set the way the reset altimeter (described below)
- Number of the competitor
When you press "Save", entered settings will be saved to the altimeter. Exit
without saving the occurs after the closing of the window (click on X).
These settings are remembered by the altimeter, even after power is switched
off. Just a single programming is enough.
1.
Setting " Measurement Start Height "
Measurements start after reaching a height set in the parameter "Start Height
Trigger" The optimum height is about 20 - 30 meters. Altimeter records
measurements from the last three seconds before detection of measurement
start level. If you set the start level too low (below 7 meters), the
measurements could be started already at the starting position (fluctuations in
atmospheric pressure are sufficient to start the measurement.) Then the height measurement
is performed until the memory is full (the level of the landing is not checked - normally set
to 7 meters). If a competitor delays the start, the whole flight may not be registered.
