Hi, I have been having trouble configuring my system to output analog voltages using a PCI-6115/BNC-2110 setup. This equipment had been working in my lab as set up by a coworker who no longer works here. In the last week, the devices attached to the BNC box stopped working.
We first noticed the problem after I added some new equipment to the computer. While installing the new equipment, I had to reset all of the comports and reassign them manually (for some reason, one of the devices had to be run on comport1). To do this I followed instructions to clear the information under ComDB in the registry and rebooted. The native comports were reinstalled automatically, and I added the other devices (USB to comport adapter devices) individually.
Now to the problem. The PCI card almost always, passes the self test in MAX. Sometimes I get an error -50103 (The specified resource is reserved. The operation could not be completed as specified.), but I can usually get that error to clear in the MAX. The power light for the BNC box comes on. And there is a constant 5V output voltage from the CTR0 out port. Also, the attached devices work when I apply 5V directly to the BNC cables that go to the devices. All of this makes me think that the problem is not in the hardware.
Still, I can't get the devices to work either in MAX, or in Labview. Keep in mind, the programs and devices have all been around for a while and have been working until recently. No hardware changes have been made. The comport changes I made, I reversed and removed the new equipment. As far as I can tell, that part of the system has been returned to its old configuration. Also, I reinstalled both the DAQmx and DAQ legacy drivers with the most recent versions.
Is there any other way to test if my problem is in the software or hardware? I have suspected that some port/device/? assignment has gotten messed up. I am out of ideas for things to test/try to get the equipment back up and running.
Any suggestions?
