Hi, We are testing our NI PCI-6713 board and it seems that the data is send as signed instead of unsigned numbers to the card. for example: outp -s 1 -c 0 2047 ==> gives +10V outp -s 1 -c 0 2048 ==> gives -10V outp -s 1 -c 0 0 ==> gives 0 V We tried to trace it where this conversion could have failed (we don't experience it with our other NI boards, same kernel module), but got a bit lost in the ioctl calls. Could you provide any hint where it might have failed ? Personally i think an (unsigned int) cast is missing somewhere. thanks a lot, Peter
