Symptoms and Actions
If Data cannot be Normally Input or Output
- Run the front panel software, and then make sure whether the device is registered, whether there is
init error or not.
- Are there any problems with items such as the device settings and the wiring method? Check the
I/O impedance, maximum input level, and pi-circuit setting.
If the front panel software works normally, and the application made by user does not work normally
The front panel software is made by using the functions of API-VNA(WDM). If the front panel software
works normally, the install driver and the recognition by Device Manager are finished normally. In this
case, the following points should be noticed. And review and correct your program.
- Check the return values of the API functions.
- Refer to the source code for the sample programs.
The OS won’t normally get started or detect the device.
Refer to the "Troubleshooting" section of API-VNA(WDM) HELP.
