I need to order sip packs on location RM7 and RM13 on a super pacman pcb. when i try and order them i get 2 choices isolated and bussed which one do i need and how do i tell the difference in the future. Thanks ,Luis
Bussed is where there is one common connection to one side. Top of the picture.
Isolated means you connect there is no common connections. Bottom of the picture.
There should be series number/ amount of pins/I or B /Resistor value.
