TRIG_TIMER works if two or more channles are used (one channel don't work) I get these error messages in the kernel log for the DAQCARD-1200 using channel 0 only: daqcard-1200: index 0x01: Vcc 5.0, irq 3, io 0x0100-0x011f comedi0: ni_labpc: daqcard-1200, io 0x100, irq 3 bad chanlist[0]=0x00b00000 n_chan=2 range length=2 bad chanlist[0]=0x00b00001 n_chan=2 range length=2 Running exactly he same code on a different machine with NI PCI-6023E card gives no errors in the kernel log. Which instruction in the driver code prints the kernel error messages ( I guess it should be somewhere in the labpc_ai_cmd function)? Fredrik
