DAQ700 PCMCIA some "high level" functions for multi channel reading doesnt seem to work

[David Norman]

Trying to use DAQ_Op and Lab_ISCAN_Op but getting the -10003 "Invalid Value Error" all the time.
Is this function supported at all? I can't find any
examples that uses multi channel reading with the set of functions that are supposed to be supported by the 700 card....

David,

These functions should be compatible with the DAQCard-700. Have you been successful performing any analog input operations with this device? Could you post the function calls, including parameter values, which are generating the -10003 error? This information could be helpful for troubleshooting.

Got the stuff working using the DAQ_Rate() function, after some time I also got the doublebuffering to work with multiple channels. If I have found an example using the Lab_ISCAN_Start() function together with the DAQ_DB_xxxx() functions I would have saved alot of time (but missed alot of fun..). I think the documentation is quite poor. I would like to see that all function description in the "online help file" came with an example of input parameters. It also takes some time to figure out what examples that works with which cards. Even good hardware is useless without proper documentation.
