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.

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.

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.

The MPEX4S952 4-Port RS232 Mini PCI Express Serial Card (16650 UART) turns a mini-PCIe slot into fourRS232 (DB9) serial ports with data rates up to 921.6 Kbps - a cost-saving solution for adding serial support to embedded systems missing the functionality. A native PCIe single-chip design enables you to take advantage of full PCI Express bus capability, by providing improved speed and reliability while reducing the load applied to the CPU by as much as 48% over conventional "bridge chip" serial cards .Backed by a StarTech Lifetime Warranty and free lifetime technical support.
Four high speed RS232 serial ports with data transfer rates up to 921.6 Kbps
High Performance 16650 UART
Includes 4x 30cm IDC to DB9 serial cables
256-byte deep FIFO per transmitter and receiver
Native single-chip, single lane PCI Express
In-band software flow control, using programmable Xon/Xoff in both directions
Automated out-of-band hardware flow control using RTS/CTS
Compliant with PCI Express base specifications revision 1.1
Applications
Add serial ports to industrial embedded computers and systems
Add RS232 serial control to an embedded or slim media center/media server/all-in-one PC
Add RS232 serial ports to slimline POS systems
Advantage
The smallest form factor available, for internally adding serial ports to any embedded system
Native single-chip design means up to 48% less load on your CPU which is critical for small embedded PCs that use low power, low MHz CPUs
