The Comprehensive Programmer begins the same way as the Basic Programmer, with a Programmer Setup Pane and a Roster Pane. The content are identical, so they will not be repeated here. Just be sure to select the Comprehensive Programmer on the Setup Pane. (Tab Programmer Setup)
When you are on the Setup Pane and click on the Open Programmer button, the appropriate Comprehensive Programmer window will open. All programmers, Basic and Comprehensive, open to the Roster Entry pane, which will be similar to that shown below. (Using Digitrax DN163K0a decoder examples)
Note that the Roster pane is essentially unchanged from the Basic programmer, but the window has a LOT more options in the Tabs at the top! If you are unsure how to handle the Roster information, go back to that section in the Basic Programmer. If you're ready to move on to bigger and better things, let's go to the next tab, the Expanded Basic Tab.
