My new computer does not have a serial connector for my old machine.
What you need is a USB-Serial adapter. There are many different brands of adapters on the market and you will find one in your local computer store… or on Amazon.
Do it yourself and read the bottom of this page or you call our store and make an appointment with Gregor and he will help you installing it.
Do it yourself method:
If you’re computer savvy you will be able to read the direction that comes with the adapter and install it with no problem. Install the driver first before you plug in the adapter!
Step1: Plug USB/Serial cable into your computer’s USB port.
Step2: Open the “ Control Panel “, double click on “System”, select the “Hardware” tab, then click on “Device Manager” and check if there is the device you install under Ports (COM&LPT) “USB to Serial (COM4)”
Step3: Now this is the most important part! If it is COM1, COM2, COM3, OR COM4 go to Step7.) and remember the COM port number. If the COM port number is above 4 keep on reading.
Note: In any Bernina or Pfaff Software program you only be able to select COM port’s between 1 and 4 to read and write to your machine.
Step4: If the port number is above 4 double click on that line. (The one “USB to Serial”) the next picture will come up.
Step5: Select the “Port Settings” tab. Then click on the “Advanced” button. You will see the below picture, after you click the “dropdown” for the COM Port Number.
Step6: Now choose a COM port between 1 and 4 that is not in use!!! In the picture above it would be COM2.
Remember that Number!!!
After you close the “Advanced Settings Window” and you get back to (Device Manager) the COM setting will still be the same as you saw it in the first place. (somewhere above 4) Don’t let that irritate you. It will be the COM port you just selected next time you start your computer!!!!
Step7: Close all the windows you have opened on your desktop. Then start your BERNINA Software program. When the time comes to select the COM port to write/read to your machine, select the number I told you to remember!
If you do not read the following…
YOU WILL BE IN TROUBLE!!
Please “mark” the USB port on your computer where your new cable is plugged in now. The next time you would like to send something to your machine and you plug this cable into another USB port on your computer, the COM port number will change and you have no clue what to select when you want to write/read to your machine!

The biggest mistake you can make now is try to adjust the bobbin tension! When the topside of the fabric looks good and the underneath of the fabric has big loops, there is something not correct with your top tension.
How to troubleshoot:
Pull out the upper thread completely out of your machine.
Raise your presser foot so your tension is released.
Thread the upper thread according to your manual: But do not thread the needle!
With the presser foot now still raised pull on the thread -> you should have no tension on the thread.
Lower the presser foot and pull on the thread again -> you should have now tension on the thread when pulling.
If you have tension on the thread -> proceed with threading the needle and try to sew again. To 99% your problem is fixed now.
If you pull and do not have any tension on the thread in point 6, do the following.
->Look at your tension dial and see where it is set on. Dial it up to 4 or 5. (most tension range from zero to nine so 4 and 5 is a good range to start) Once you turn the dial to 4 and you have now tension when you pull on the thread, look at point 6 and you are probably home free.
If the tension is set on like described in point 7 and you still have no tension you need to try to clean the tension.
How do you clean the tension. Since different machines have the tension units in different places, there are only some guidelines I can give you on how to do it.
In order for you to understand what you need to accomplish by cleaning the tension, I have to show you the principle on how a tension works.
The picture below is the most simplest tension there is on a machine, but all other tensions in any machine in the world the are built the same way in one way or another.
How any tension works: As you turn the dial against the spring you are increasing or decreasing the pressure against the tension disks. The red dot is the thread. As you put more pressure on the spring you increase the tension of your machine.
Over time, dirt, lint and pieces of thread will accumulate on the bottom side of the tension rod. Eventually you will get so much “stuff” under there, that no matter how much pressure you will try to apply to the disks, the thread will have no tension.
Cleaning procedure: Lift up your presser foot so your tension is open.
-> remove your upper thread!
->with the longest straight pin you can find you go now down into your tension and try to clean the “green” stuff out. Remember if you have a modern machine, you will see only the disks above your sewing machine cover. The rest you won’t see.
After cleaning, go back to point 2 – 6.
If that still did not work out, bring the machine to your favorite sewing machine technician for repair.
