You need to make sure you have a network card installed in the jlcooper. Usb or rs232 modules will not work.
You wil need to set the ip address and port on the jlcooper and again on the prefs page of resolve. I set my port to 50000.
If connection fails at any time , it will be the port number on the jlcooper which will have spontaneously changed. Just change it back. Its set using a two button combination.
If you are doing 2d colorwork, the jlcooper is pretty nice, except there is no reset button for the rotary encoders. Don’t attempt to use it for 3D stereoscopic. All the 3d shortcuts which are mapped on the Tangent Wave panel are missing on the JLcooper. That’s not a critcism of JLC… Its DaVinci who decide what is mapped and what isn’t.
