Are there any ways to know which output goes to which COM port? (Without having to connect a device to each one by process of elimination). ?

I am sorry, but I do not have a number for my conduct. It was necessary to use the program for each and every piece of equipment to eliminate the other three Com ports.

The number of ports is now 12
5/5

This is a very reliable source. A simple installation process takes only a few minutes. The price was well worth it. On my low-profile Windows 10 desktop computer, I have 3 of these installed. My card was recognized immediately after installation, and installation was simple and straight forward. It was ok to add 2 more cards. There were no problems. In this current PC, I now have 12 ports, plus a built-in port. I used to have USB based ports on this particular PC, so I had gaps between ports. To see all the devices I had to go to device manager, then serial ports, then Devices that are not currently present but have been defined will show up in this table. Take them off the list and renumber them. that all the ports are working properly, everything is To be safe, I put tags in each of the ports. The use of serial ports on PCs has mostly fallen out of favor, but I have a room full of equipment that GPSDOs (please make sure you look this term up) are hooked up to a PC now so that they can be monitored, and tests run Additionally, I've tried USB ports, but some of them mysteriously changed their names, and I just didn't know what to do. Even though it costs more than a standard card, its performance is outstanding. I'm a PC addict from the time when PCs were This was the first time XT had been launched. It can be a mess to set up multiple serial ports, regardless of how simple they are. It is possible that a cheap one will work, but sometimes the drivers will not. It's also not a good idea to mix brands. Because of this, I simply chose brands I was familiar with. It leads me to think that I made the right decision (this one).

I am unable to use the 64-bit driver for Windows 10 A little
3/5

It's taken me a couple of hours to try to get this to install on a 64 bit machine with Windows 10. Because of the fact that the drivers included with the card didn't work, I used the latest drivers from Startech's website. When an exe is run, the installation ends without explanation. Once I cleaned up the mess it left, I tried updating the drivers for the device directly through windows, but it oddly installed a new multifunction device and changed the name of the PCI Despite this, the serial port still says that there is no It took me one by one to update drivers for each port per star tech's instructions but there was no luck and any further reinstall or update results in driver installation errors. It has already rebooted three times and crashed two times due to blue screen driver failures. What kind of hardware can be released without working Windows 10 drivers? The items will return to the company.

I've tested it on Win 10 and it works great! With my high end Win 10 PC, I explored a variety of four port units from other companies but was unable to get them I was pleasantly surprised that the device, with purported Win 10 support, worked flawlessly
5/5

Note that you must manually install the driver for each of the four ports by going to the device settings. This is a simple process that takes a few seconds. As for configuring your ports, unplug any USB that could be using a serial converter to grab a COM port, reboot, and then choose the port, advanced, and assign the COM port number you want. Plug back in any USB and let it reassign. My use of this has been flawless so far in the case of amateur radio equipment.

As it should, it works well
5/5

An Opera IFC workstation will receive additional USB ports with the help of this. This is a simple process and the software installs without a hitch. There is no need for 8 vendors, but just 4, and other vendors have all sold out.

This device is a lifesaver for people who need to connect old scientific equipment
5/5

It can be a lifesaver for people trying to connect old scientific equipment to modern computers, because the serial port is no longer used in modern computers. Much safer than the USB interface. With serial bridges, there is no chance of COM numbers hopping around when you unplug something.

This is the perfect solution
5/5

Low-profile 4 port serial card is the perfect solution for the home automation servers that our company provides, as well as the software we provide to manage the home automation. As a result, it is small and fits nicely into the Dell OptiPlex PCI Express port. The breakout cable allows the customer to label the various connections to his/her system, such as a security panel, lighting control system, IR interface, HVAC controller, etc. Please continue [
