Initialize the machine- IN;\n2. Pen Up command - PU\n2. Pen Down command - PD\n3. Pen moves to x,y position, absolute from origin - PAx,y\n4. Pen moves to x,y position, relative from current position - PRx,y\n\n## HOW TO SETUP CONNECTION TO PLOTTER\n\n### Connecting to the device\n\nPlease look in [/manuals](https://github.com/CreativeInquiry/-plottertwitter-Templates/tree/master/manuals) for the MH871 manual and how to setup the Mk2 on OSX.\n* if you are using a Keyspan Adapter, [install the Keyspan driver](http://www.tripplite.com/support/downloads/tab/1/mid/USA19HS) for your adapter's specific model  \n\n#### Connect to the MH871-MKII Pen Plotter via the COM port.
