IO_AI Buffer Read error programming Iotech DAQ 2000 board.

[fvid]

Hi,

I am new to Labview and am using Labview 5.1.

I am trying to collect data from a multifunction Iotech Daq2000 board and save data into records.  I am collecting the data, saving it, waiting a few seconds and repeating the same procedure.  The first record saves correctly but I then receive the following error while recording the second record.  Further  probing indicates that the error occurs in the daqAdcTransferGetStat VI and the error appears to be related to the Device Handle.

Thank you for any help.

Error -115

This error occurred first at the IO_AO Control VI immediately after a record was completed.  It then appeared a second time at the IO_AI Buffer Read VI part way through the second record

Possible reasons:

Windows GetCommError: the hex value of this code is FF8D

Interpret it bitwise as follows:
X4000: serial port VI error
X0001: receiving queue overflowed or character was received after end-of-file charachter
X0002: character was lost by overwrite
X0004: parity error
X0008: framing error
X0010: break condition
X0020: CTS timeout
X0040: DSR timeout
X0080: RLSD timeout
X0100: transmission queue ws full when new character arrived
X0200: parallel device timeout
X0400: parallel device I/O error
X0800: parallel device not selected
X1000: parallel device out of paper
X8000: requested mode is not supported or the idComDev parameter is invalid
Consult the LabVIEW serial port manual for more info.

Hello,

The problem you are seeing seems rooted in the driver for your lotech card.  Since that isn't an NI product, you may not find many people with experience using it here.

Sorry I can't be of more help!

Best of luck!
