Hello,
 My DAQ PCI-Board (Keithley KPCI-3103A) is connected to an Ultrasonic Card, with an Analog Output and Digital IOs, i can read the Analog Output of the Sensor(Ultrasonic Dual Use), but it´s  not significant cause I must control the Sensor to Send or recieve with the Digital Outputs from Matlab through the PCI board. How can I do that ? any tutorials or any tipps are welcome.
 For more Informations the DIOs must be adjustable.
 should I do that first with a GUI, or is it possible with Simulink , or Both ??

Thanks
