Right now I have my layout on DU track power running TMCC on TR4 for one table. My AU track power is set for TR1 which is not running any track power but is working when I power it up. At our new house I'm going to add two additional tables (4'x16' & 8'x20') looped to my original table. (8'x30'). I'm afraid that putting all 3 tables only on one terminal will overwhelm the track power on DU. Since I'm ignorant about electrical issues, I read the ZW manual and now I'm confused. Is there a simple way (I lost the program key for the ZW in the move) to phase both DU and AU together so I can power the two new tables and the one old table using track power off of both terminals? If I can, what TR# do I use on the command handheld? Thanks to all!!!
