The PGDU card for a 124i has four ports that can be switched to be Door box ports, or paging outputs with a switch on the card. Is there a way to tell which ports are in each mode without opening the cover and checking the switches?

Also, when using cmd 0091 (view system report) on a 124i, there are 4 "note" lines for each slot. Is there a table of what each code means?

For example, my PGDU card in slot 8 has:
NOTE1: 03
NOTE2: 01
NOTE3: 04
NOTE4: 04
The 8DSTU cards have codes 8, 7, and 2 (depending on the card)
