2-Port Pci Express Rs-232 Db9 Serial Port Card For Windows Xp, Vista,7, 8.X, 10, 11 32/64Bit And Linux Pcs, Pcie Rs232 Card, (Pcie-Se2)

Worked perfect in a Dell mini computer under Windows 10. No problems communicating with any serial device I have needed to. Highly recommended.

Connected the card , I had to get a PCIe extension cable . It works , only issue was finding the 64 bit windows 11 drivers . Working great now . Would buy this product again if ever needed.

I have been trying to get the CAT port on my old Yaesu FT-847 working for some time now. Putting a scope on the Rx pin of the radio I noticed that the levels seemed very low at about 3 volts. This was using a USB serial port CAT cable purchased specifically for this radio. I thought why not try a more traditional serial port and ordered this product. Installation went smoothly and my Windows 11 PC soon showed two new serial ports. Connecting one to the radio with a F-F null modem cable and initialized everything at 4800 baud. Bang just like that the CAT port lit up and started working. Looking at the levels on the scope, they are more like 10 volts now.

I used it for my Amateur radio hobby. It made a program, that I could not get to work, worked as I was hoping it would.

I had to install an extra patch from the AUR to get the ASIX AX99100 chip to work on a modern Arch Linux install, and I'm having trouble getting this to work in early userspace -- GRUB doesn't see it, and the driver is loaded late into kernel initialization (so it's trickier to get console= to work). Figured I would flag this for anyone else trying to use this for kernel console access.
