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 Serial DB9 Port Card (PCIE-SE2)

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.

Works perfectly - If you are running Windows 11 you do not need to use the CD to install the driver - Just go to Windows Update and go to Advanced Options - Driver Updates (You will need to do this twice as the first update is for the controller, the 2nd update is for the COM Ports themselves).

Purchased to connect my Kenwood 2000 and my Kenwood 590s to my computer and be able to run programs from Kenwood and Ham Radio Deluxe. Unit comes in a full style profile and needs to be separated to connect to a low profile style computer. I have big hands so it was a PIA for me but got it done. Installed CD and looked for windows 11 64 bit driver. Ran setup and it was done. Both radios connected without issues. Just make sure to setup your port for the radio. Mine was 5 and 7. Also if you have no Cd player you can do a search for the driver on the CD and it will be available for download for free.

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.

I struggled with USB to RS232 adaptors and drivers far too long. This board worked as soon as the driver were installed. Driver included on CD!

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

I have an old Zebra ZM4Plus and this was the only way to get a new server to communicate with it. USB to Serial did not work. Anyone out there reading this review, please know that the old Zebra printers do not communicate with those USB to serial devices, you need the PCI or PCIe direct to motherboard communication.

I rarely write reviews, but this purchase deserves one. I was struggling trying to connect a Cisco Catalyst 3560 switch to be programmed to my 16 year old HP pavilion PC running Windows 10 Pro. I purchase a few adapters and cables on Amazon and they never worked, until I came across to this product and decided to buy it. Guess what, after a successful installation I was able to stabling communication from my pc to the Cisco making possible to be programmed. This product works if you know what you are doing. Thank you seller.

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 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.
