Hi Jerry,

ACP use the Digital Loggers switch by using the ASCOM switch driver configuration. Run the AscomDigitalLoggers.vbs file at C:\Program Files (x86)\Common Files\ASCOM\Switch\AscomDigitalLoggers.vbs to change the ip address according to your switch.

If your switch has a fixed ip address, the address must be in the same subnet as your router. The easier thing is to change the ip address of your router to the same value as the older one. Not all router companies have the same default ip address. ( ; ;; etc)

Hope this help!
