Any solution to PDA error code 200361?

[Mathieu Hamel]

Hi,

I am able to acquire 16 channels @ 350 Hz and stream this data using TCP/IP on the host computer. It works fine, but the limit seems to be around 400 Hz. Here are the settings I used:

Pocket PC, iPAQ H5500, DaqCard 6024E
Task: 350 Hz, 16 NRSE, bipolar, with a scan rate of 100000
I am reading the data with RAW 1D I16.
I am using the Queues functions

In its cradle, I did a 2 hours test and its stable. Using the batteries, I have a problem then reaching 37% of the battery capacity. In fact, my application crashes because the PDA post a "low batt warning message". If I ignore this message I am able to stream data for about 1 hour 20 minutes. Any ideas?

Hi Mathieu,

When the PDA is running solely on battery and teh battery is running low, the CompactFlash bus in the PDA is affected. If you recharge the battery or run it from its AC adaptor, the driver will recognize that there is enough power and will re-enable the CompactFlash slot in the PDA.

Thanks,
