Hi Carideom,
Thank you for using our discussing forms.
First off I want to tell you that there should be no conflict when having an E-Series and an M-Series Card installed at the same time. Currently I have both installed and I don’t run into any problems. I realize that you have read the knowledge base article regarding the error 50103, and I am just going to add that you can’t have more than one analog input or output task occurring at the same time on the same card. Now the E-series card that you mentioned is supported under traditional DAQ so for one reason or another it may be reserved by the traditional DAQ driver. If you reset this driver it may solve the problem. To do this right click on the Traditional NI-DAQ(Legacy)Devices selection in Devices and interfaces of Measurement and Automation Explorer and select reset driver. Then right click the actual E-series device under DAQmx devices and select Reset Device.
If this doesn’t fix the problem, I want to check is that you have the DAQ card properly configured in Windows Device Manager (no yellow exclamation mark) and Measurement and Automation Explorer. If it appears properly in both locations, lets first try and create a Task with the M-series card and perform an acquisition. If this is successful, and I am assuming it will be, lets not create a new task, but rather change the physical channel of that task to a input on the E-series card. Let me know if this causes the error. If you are unfamiliar with MAX, and have access to LabVIEW then you can try this same thing with one of our examples programs. Under help>>Find examples, browse to Hardware Input and Output>>DAQmx>>Analog Measurements>>Voltage>> and select any of the examples. Try the acquisition on the M-series and then the E-series.
Let me know the results of these test, and if you run into errors let me know the errors that you get. Hopefully we can get this problem solved.
