Does not work with large files transfering

Our application requires large files download (3MB) with baud rate of 115200 and using this model of device we are getting many issues, mainly loss of data and comunication being stopped. We have no issues with other models

Does not work in Window 10 Enterprise IoT LTSB. Com Numbers are duplicated to the onboard COMs. There is no way to modify COM numbers.

Works perfectly

We use these cards for all our PCs that connect to scientific instruments (Agilent etc). No problems getting the drivers installed or the instruments to communicate. Solid cards that just work. Can't recommend them enough.

Suggestion for documentation

An arrow showing where pin 1 is for the parallel cable would've been helpful. The stock photo provided on Amazon, CDW, and shown on the box contradicts what is show on the front of the manual.
