I cannot acquire more than 5 Channels with the SCAN_op function

[Junior Electronics/ Software Technician]

Any time that i try to acquire data from more than 5 channels in labwindows CVI, i get an error that says "BadchanError - A channel, port or counter is out of range for the device type or the device configuration." I am using the function call:

SCAN_Op (1,14,chan, gain, buffer2, 1400, 1000, 100);

where buffer2 contains 1400 elements, chan contains 14 elements (0-13) and gain is an array of 1s. I initialized the card by using

Init_DA_Brds (1, &b_code);

do i need to perform more initializations? how can i make this function read 14 channels of data?

Greetings,

It appears that you are using the SCAN_Op function correctly. Do you receive this same error if you execute the SCANsingleBufSync.PRJ example with more than five channels? Additionally, what hardware are you using?

Let me know.

Thanks for the help, but i figured out that i needed to initialize the Channels on my DAQ- Card (6036E) as non referenced single ended in MAX, i didnt realize that i had it initialized as differential, which solved the problem.
