Compatibility This circuit board is compatible with all Pro Logic “P-4”, “PS-4”, “PS-8” and “PS-16” units.  The microprocessor software will automatically check the type of local display that is connected and adjust the Pro Logic features and operation to match the appropriate model type.  If no local display is connected, or if there is a problem with the local display and it does not respond to inquiries from the main PCB, then the main PCB will assume that the system is a Pro Logic P-4 model.  If this occurs:  First fix the problem (install or fix the local display) and then cycle power off and back on.  The Pro Logic will recheck the local display and operate accordingly.
