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.

The PEX1S553LP PCI Express Serial Card is a high-performance solution that transforms a PCI Express slot into a robust RS232 (DB9) serial connection. This advanced card is engineered with a native single chip design, allowing you to leverage the full potential of PCI Express (PCIe) technology. Remarkably, it reduces the CPU load by up to 48% compared to traditional bridge chip serial cards, enhancing system performance and reliability.

This PCI Express RS232 Serial Adapter Card boasts wide compatibility with an array of operating systems, including Windows 2000/XP/2003/Vista/Windows 7/Server 2008 R2 (32 and 64 bit), and Linux Kernel 2.6.11 and up. It comes pre-installed with a low profile/half-height bracket, but also includes an optional full profile bracket. This flexibility enables you to add a serial port to virtually any computer, irrespective of the case form factor.

The product is designed as a replacement for the PEX1S552LP card. It features one high-speed RS232 serial port with a data transfer rate of up to 460.8 Kbps. The card is equipped with a selectable power output on pin 9 for the serial port, and a 128-byte deep FIFO per transmitter and receiver. It also supports automated out-of-band flow control using CTS/RTS and DSR/DTR, as well as automated in-band software flow control using programmable Xon/Xoff in both directions.

The PEX1S553LP PCI Express Serial Card is compliant with PCI Express base specifications revision 1.1a. It is easy to install and use, coming with comprehensive step-by-step instructions to save you time and hassle.

This versatile card finds applications in self-service automated machines and kiosks to control serial devices such as scales, touchscreens, magnetic card readers, bar code scanners, receipt printers, and label printers. It's also ideal for bank teller workstations, POS retail applications in grocery stores and other retail outlets, standard ATM automated teller machines, and for controlling multiple surveillance/security cameras in parking structures, office buildings, and more.
