Your Right, this is not the usual. I have a lot of tac 20s and all of them can be programmed through IMS from the machine room. Then one day we picked up a couple of tac 50s with these 6300GE Stand alone door boards. I was thinking they may have put in some kind of stand alone board in his job also. I'm not familiar with the 6300PA6 board but World Electronics does sell a 6300PA replacement board so they must know how its programmed.
