Digitus Usb To Serial Converter Driver Windows 7 Download

[Fisseha Aranda]

Iconnected my USB to serial converter to USB (using latest FTDI drivers 2.12.0.0, i can see new USB serial port in device manager under COM3). I prepared a loopback connector just like in article above (both socket and plug pins are numbered so i double checked they are right, i also tested connectors to see if singal can pass).

It happens if write is On and read is Off. It also happens if write is Off and read is On and happens when both read and write are off aswell. It also happens if the string to write is default "*IDN?\r\n"

The exact same thing was happening at other computer (with older labview and older ni-visa drivers) and i thought its because of not up to date drivers thats why i tried other computer with stuff that is up to date.

Also, could you point out from where did you download the drivers ? You have mentioned that you have an Windows 8.1 OS - I have checked this device on the Digitus website ( -and-converter/r-usb-serial-adapter-u... ) and it appears that it supports only up to Windows 7.

I found what was causing the error. It was because the converter im using does use DB9 type plug BUT the only signals that are coming out of it are RS485 A and RS485 B (half duplex), just two pins + GND (the TxA TxB RxA RxB are connected inside the case) so loopback plug was completly wrong.

In the end i had to find a second USB to RS485 converter, plug them both at once to computer and connect each others A and B signals and when in one terminal window i sent "test" the other terminal window from other converter recieved "test"

The one weird thing i noticed is that when i sent "test" (send as ascii) in one terminal (one USB to RS485) converter when it sent that msg it recieved null character and the second terminal window (another RS485 converter) recieved "test" but ended with a null character aswell. I dont know if its normal but ill try to ask around somewhere esle, since its less and less releated to labview.

I just got a new pc and I did not notice that my vid card only has one port. I want to be able to plug both my vid cards. So I brought out my old vga adapter but I can,t find the drivers and just plugging in my Win 8 machine does nothing.

More information on the device would help. Have you tried simply plugging it in and rebooting, and see if Windows will see it and load drivers for it or going into Device Manager and scanning for hardware changes? Does DM see the device?

Depending on how your new PC is built, you may be able to just add a second video card to resolve your issue. Are there any open slots on the motherboard that would allow you to add another video card?

Check the device manager for the Unknown Device, Right click it and choose Properties. Now under the Details tab select Hardware IDs and look for the Dev/Ven ID tags and look em up at that should lead you to the vendor, and hopefully a driver or a different reference point to Google from.

I wonder though, does that give you the functionality of dragging windows to the different screens and having stuff show up on only one screen like with dual video cards, or does it just duplicate your screen like it is one?

I got a VGA Splitter, and it will only show the same screen on both monitors. I have a usb to vga adapter that worked great in Win 7, but my computer crashed. My recovery disks would only work to do a "clean" install and delete ALL of my old files and software. : ( . I have dual OS on my computer, and when it crashed, although I could see that Win 8 is still there, I could not boot to it. I still don't know if I can, since I'm trying to get Win 7 back to a usable state. BTW, I have Win 8 on my tablet with keyboard dock that turns it into a laptop (sort of), and on the desktop AND the tablet, I HATE WINDOWS 8. And, I checked with Windows 8 support, and they told me that the only way to use 2 monitors to extend your desktop you have to have a video card with 2 monitor ports or install 2 video cards. I have a slot open, but can't find a card that will fit in it.(height problem). Now I can't find a driver for my usb adapter. If I could, I would be a happy camper right now. I NEED 2 monitors to run my in-home small business doing simple graphic design and heat process/dye sublimation products. I've got orders and no money at this point to buy another system, if I could find one with Win 7 and 2 monitor ports already in it. If I couldn't find one, I'd still be where I am right now. Anyone know of any FREE driver download sites? I've used a couple before, but of course don't have the URLs, since my old docs were wiped out. Help please!

The y adapter can work but only if you have a motherboard/video card intended to be used with one enables multiple display. Dell made some of these, the cables have a special pin out and requires some proprietary hardware. Otherwise you are out of luck to do it with a splitter type of cable.

This may be an older version of the digitus usb 2. to vga adapter. This website has drivers for the current version. It is possible but unlikely it could work for you. I'd tend to think if you had this device working in windows 7 that you should be able to get it going in Win8. Assuming you had 32 bit windows 7 and went to 32 bit win8(or 64 bit to 64 bit)

If this device driver doesnt work then you need to figure out who makes this usb to vga device for us to be able to help you with it. Either follow the instructions above to find the hardware ID in device manager, or find some identifying name on the device.

If as you said you have a video card with one connector you could consider replacing this card entirely with a card that has two ports. This is a pretty standard feature and a decent card won't cost you a lot.... You could also buy just a cheap card to do this and pull it/replace it with your current card for gaming. You'll need to determine what type of slot the desktop has and if you have some kind of slim case find a card with dimensions that will fit but not a real tough thing to do.
