Thanks everyone! After ordering the correct cable it worked perfectly. I got this out a gross garage so now I get to clean it up, order some blades and get to work designing! You guys were a huge help. Thanks again.

Well, I was able to download the trial software and get it installed. I was also able to get it detected in VinylMaster (demo) but when I go to cut I get the "sending to cutter" dialog box and it just hangs. Never sends data... so I'm getting closer but still no luck. Right now I got the Tripp-lite thing connected direct to the cutter and the USB run into my computer. Nothing super fancy going on.

Well, somewhere I was told to download a driver file called CDM20828_Setup.exe which is a USB serial converter. As far as the cable goes, I used the one supplied with the Tripp-lite adaptor I bought off this site. I didn't install drivers for the adaptor though. I'll try that next. It does list in the device manager as Keyspan USB serial device (COM3) under "ports" which is why I didn't bother hunting down drivers for the adaptor but it's worth a try I guess. I suppose I could try another email address as well but I'm pretty sure that's not gonna help. I own the domain so it's not black listed or anything. I have a few others though. I'll try them.

I recently came upon a MH721 and it seems it doesn't have a USB port. I was instructed to get a keyspan USB to serial adaptor so I did. I hooked that all up and it is showing up in device manager on COM3. I tried to install device drivers and it appears to work however the cutter doesn't show up as a printer in my settings (windows 10). I tried to use SignBlazer and I can find the KEYSPAN in the settings but when I try to cut I get the typical error which I see all over this forum "cannot open the output device. Error initializing cutter". I also tried to do download the VinylMaster demo but I never receive the email to download it (not in spam filter either). I'm willing to buy the software but I just want to see this thing work before I invest any more money in it. Can anyone help?
