The accompanying disc doesn't include drivers for Vista, but the box says it does. Where can I download them ?

    Thanks for the link. I'll try it tomorrow. I did my own "fix" in the meantime. For some unknown reason one of the 20 laptops I had to install on actually worked with the Nikkai RS232 adaptor, none of the others did. I found the installer puts two .sys files in the C:\Windows|?System32\drivers folder. I tried copying these from the one working laptop onto the other 19 laptops also using the blue CD, replacing the two .sys files, and if by magic, they all now work !

    Cheers, Tony

    No problem, you are probably better using this driver as it was written for Vista.

    I found it by searching for the prolific driver for serial adapters instead of Nikkai, as they are the supplier not the manufacturer.

    It definitely works for me, I didn't want to mess around with manual install/copy of files, Not that I wouldn't be adverse to doing that either....

    Anyways thanks for the update and hope all works out for you.

Have just purchased a USB 2.0 to SATA HDD Adaptor made by Nikkai from Maplin. Have connected everything okay with my old HDD but when I go to run the 'Driver & User Manual' disc it just tells me it a...

Most of these adapters don't need windows drivers EXCEPT for use on a '98 system.

Got to the disk management console & see if your USB drive is there. It may simply need to have a drive letter assigned for you to see it in My Computer.

The path to the disk management console is usually: %SystemRoot%\system32\compmgmt.msc /s

Paste that into Start/Run.

Problem printing from Dell Inspiron 1720 with Vista Home Premium to Epson Stylus Colour 1160 using Nikkai USB to Parallel Convertor. Cable supposed to be plug and play. Any pointers?

You pretty much said it when you mentioned "Other than buying the cable in the first place" I have never successfully used a USB to parallel converter cable on any system. My suggestion, asisde from getting a true USB printer, is a parallel port card

I have an rs232 cable attached to kyrptview cable box via a usb adaptor.. Cant get my pc to see the box.. its a dell pentium 4 on windows xp.. any help pls

I assume the RS232 cable is going to a serial port? I think you should add a USB card to your system. The old async chips used to support RS232 ports are not fast enough to take USB info.

Need drivers for nikkai usb to serial converter rs232

I purchased the Nikkai USB to RS232 adapter from Maplin and could not get the device working. (Maplin staff not much help!) The lead uses the Prolific PL-2303 device but Prolific do not supply the drivers to end users.
However I found the drivers that appear to work at:

This then recognises the lead as a COM port. So far everything seems to work OK.
(Null modem check and basic 9600 data transfer.)

I hope that helps everybody.

Can't even start Metrologic voyager 9520

The MS9520 with RS232 needs the AC adapter plugged in to operate, the adapter plugs into the serial cable at the plastic "bulge". Cable part number is 53000c-3
Hope this helps, Terry @ TAG Technical INC
