Looking for a tac 50 manual. I have t4, tac20, tac 32. But no Tac50. Happy to trade or help others. I have a IMS 50 on the lap top but I don’t know how to reprogram the door board. No limit led’s and the board won’t open or close the doors from the open/close buttons on the door board. I’m making the assumptions it’s the door board. Tried to plug the IMS laptop in and the battery was dead and so,was the charger. A lovely way to start the day. Had a nice big power bump this morning.. loving life. Thx!
