Well yes.
The yellow course has to be on Address 2 and the Green course on Address 4. We are sure that an update to the NASTAR software will allow control over the display duration and allow a test pattern. The current designation is 80-EO due to the type of display the programmer has.
The new NASTAR software should allow you to specify the Address of the display. The standard before was ALGE address 2 for Yellow and 4 for Green
What configuration do you have? 6 digit, 8 digit?
