Guest Nicole Posted July 8, 2022 I recently purchased a US cutter SC2 34in and unfortunately it will not detect the DCOM connection. I did have to get a DCOM USB connector since I am working from my laptop. Please let me know any advice and anything I can troubleshoot. Quote Share this post Link to post Share on other sites
MZ SKEETER 4,708 Posted July 9, 2022 A Tripplite Keyspan Adapter is what you need to connect to your laptop, with a null modem cable. Tripplite is the brand name that works with a vinyl cutter. Find the best price. Download driver, reboot computer. The USB part of cable goes is in your USB port of computer.. Connect the end of Null modem cable to your Keyspan Adapter, then the other end of Null modem cable to your vinyl cutter. , go into device manager, find com port number, I must be between 1-4. The go into your cutting software set up and choose the com port number. They must match. https://www.amazon.com/Tripp-Lite-Keyspan-High-Speed-USA-19HS/dp/B0000VYJRY/ref=sr_1_4?crid=L3BIJ9BYB5XP&keywords=keyspan+usb+to+serial+adapter&qid=1657331931&sprefix=keysp%2Caps%2C261&sr=8-4 Sign up and enjoy this forum.

darcshadow 1,625 Posted July 11, 2022 Tripp Lite is the recommended manufacture, they are known to work and work well. What you have, may work, if you set it up correctly as Mz Skeeter described. If you still can't get it to work try a Tripp Lite adapter. Quote Share this post Link to post Share on other sites
