Vision Acquisition Software 18.0

IDFixed Issue
220427IMAQ Close and IMAQ Stop appear to hang when the acquisition is waiting for a trigger and the timeout has not yet elapsed.
692292Existing 1473R bitfile cannot be used in LabVIEW 64-bit.
678251Vision RIO output lines glitches when driving lines from different applications.

Vision Acquisition Software 18.5

IDFixed Issue
712396For Camera Link cameras using NI-IMAQdx, the TriggerDivider attribute doesn’t error when set to 0.
711898For Camera Link cameras using NI-IMAQdx, the InvertLine attribute does not work on User Outputs.
710873Non-streaming GigE Vision devices fail to open in NI-MAX.
709909If a USB3 Vision camera has a flaky connection, the OS can renegotiate the connection and temporarily double enumerate the device before cleaning up the first instance, causing the driver to incorrectly not identify the original camera session as removed.
707598After a camera is unplugged, the driver sometimes returns no acquisition in progress error instead of camera removed error.
707491Unplugging a camera during an acquisition can cause a crash in LabVIEW or result in GetImage returning “Attribute not supported by the camera” instead of a more meaningful error.
707402When a USB3 Vision camera is removed, subsequent calls to GetImage return timeout instead of more meaningful error indicating the camera has been unplugged.
707186If the USB stream of a USB3 Vision camera experiences a communication failure during an acquisition, GetImage() returns timeout instead of more meaningful error.
705795If an NXG VI has multiple resources controls, each control may not correctly refresh the list of currently available devices.
704305Blue Screen can occur on Windows when performing serial read and write operations on Camera Link.
507186A One Shot acquisition cannot be started again after it has completed without first unconfiguring and configuring the acquisition.
173143One Shot acquisitions do not correctly indicate that the acquisition is complete after all of the buffers have been acquired.
716920The 1433, 1435, and 1437 can experience unreliable serial communication about 115200 baud.
717882Linux Real-Time target with a USB3 camera connected can become unreachable through NI-MAX after NI-IMAQdx 18.5 software install.
719679When upgrading to Vision Acquisition Software 18.5, the Vision Acquisition Express VI might not be available in certain versions of LabVIEW.
