Issue Details

I am seeing a resource reserved error when I add in a RTSI cable between the two PCIe 6353 cards and I try running two DAQmx task with multiple channels. I checked the device routes in MAX, and it suggest that there should not be an issue.

Error -89137 occurred at an unidentified location
Possible reason(s):
Specified route cannot be satisfied, because it requires resources that are currently in use by another route


In order to get around this error, make sure to use the same DAQmx reference clock for both tasks instead of a DAQmx sample clock. Here is an example of the setup for M series devices, but it can also be used for this case. If using LabWindows/CVI™ then be sure to use the Refclk_Src and Refclk_Rate commands.
