StarTech.com 2-Port PCI Express Serial Card with 16C1050 UART - RS232 Low Profile Serial Card - PCI Serial Card, TAA (PEX2S1050)

Newer bus designs are great, except when they remove one's ability to utilize the standard hardware that some of us still require like RS232 ports. The USB adaptors do not give us an official RS232 port, but a pseudo-RS232 port which might work on most devices, but are incapable of working on those which require real RS232 levels. This card is the solution, as long as you have an available PCI-E slot in your computer. It worked fine on Windows Server 2022 with the latest driver available on StarTech's site.

Plug & Pray? Not at all in my W10 puter. As soon as I loaded the drivers, it popped up in Device Manager as two working comm ports.

New PCs do not have serial ports anymore, so needed one to communicate to my (older) GPS unit. This card installed quickly and was an easy setup, although did have to help the driver install a bit.

Im using this card to send programs to a 1996 HAAS HL2 CNC Lathe, Ive tried two different card to use in my Windows 10 PC

I've had to return the card.For the technically inclined or interested parties:No support for FreeBSD. I needed a specific targeted application which is best suited for running on FreeBSD. If you need FreeBSD support, make sure you check /usr/src/sys/dev/pub/pucdata.c or /usr/src/sys/dev/uart/uart_bus_pci.c for support. Make my mistake for forgetting to check the kernel for hardware support to your benefit.Card is properly identified under FreeBSD (you're able to enumerate the PCI bus and identify the card) but there is no driver to operate the 16C1050 UART. What is a 16C1050 UART anyways? I can't even find technical specifications for this chip. This means even if I wanted to modify the FreeBSD puc kernel driver, I couldn't because there are no published specifications for this UART to be found. This is not just this board but any board that was "compatible with 16C550" or similar verbiage you'll need to exercise caution. This and similar boards which are found on Amazon.com should be avoided at all costs because they will require specific vendor drivers which tend to be undocumented and loose support across operating system upgrades. Do yourself a favor and find yourself a native 16550A, 16650, 16750, or 16950 UART on board.Output from pciconf -lv:pcib3@pci0:2:0:0: class=0x060400 card=0x00000000 chip=0x10801b21 rev=0x04 hdr=0x01vendor = 'ASMedia Technology Inc.'device = 'ASM1083/1085 PCIe to PCI Bridge'class = bridgesubclass = PCI-PCInone1@pci0:3:0:0: class=0x070002 card=0x4d0214a1 chip=0x4d0214a1 rev=0xb0 hdr=0x00vendor = 'Systembase Co Ltd'class = simple commssubclass = UARTI ended up buying a SIIG 2-Port RS232 Serial PCIe with 16950 UART (JJ-E02111-S1) which has the Oxford OxPCIe952 chipset in it. There is listed driver support for it and is found in both the uart and puc drivers of FreeBSD's kernel. It has two native 16950 UARTs on board.You can see here the SIIG with the Oxford chipset does have support and I verified!:root@foobar:/usr/src/sys/dev/uart # grep -i OxPCIe952 *uart_bus_pci.c:{ 0x1415, 0xc120, 0xffff, 0, "Oxford Semiconductor OXPCIe952 PCIe 16950 UART"-and-root@foobar:/usr/src/sys/dev/puc # grep -i OxPCI *pucdata.c: "Oxford Semiconductor OXPCIe952 1S1P",pucdata.c: "Oxford Semiconductor OXPCIe952 UARTs",pucdata.c: "Oxford Semiconductor OXPCIe952 UARTs",pucdata.c: "Oxford Semiconductor OXPCIe952 UARTs (function 1)",pucdata.c: "Oxford Semiconductor OXPCIe954 UARTs",pucdata.c: "Oxford Semiconductor OXPCIe954 UARTs (function 1)",pucdata.c: "Oxford Semiconductor OXPCIe958 UARTs",pucdata.c: "Oxford Semiconductor OXPCIe958 UARTs (function 1)",That's all folks!

I needed a COM port to download power quality analysis files from my older Amprobe, and this works flawlessly. Very satisfied with the product!

The hardware install is like any PCIe card, but for Windows 10 there is no published driver to be plug-and-play. The driver from the mini CD that comes in the package is not digitally signed and would not install on Windows 10.I expected more from StarTech.

Necesitas buscar el driver solamente pero trabaja muy bien.
