So I just got the Keyspan serial connector as recommended by Mac users here. I installed the drivers, but most have some setting wrong since the cutter is still not working.
When I go to Networks in System Preferences the Keyspan is there (2 ports are showing up, KeySerial1 and USA19H64P1.1) I've tried both with no luck. Both say not connected in Networks, I click connect, nothing happens, except once the cutter started to move, rollers moved one inch at a time for about 45 seconds, then nothing. Still said not connected afterwards.
Pretty sure settings are just not correct, but can't find the correct settings anywhere to compare them with.
I am using SignCut Pro.
Thanks.
