Figure 3-15. StringPin Controller Box - Internal Components
The following is a description of the functions of the StringPin Controller Box internal components:
(1) I/O PCB
- Circuit board that provides the connections for the low voltage signals that connect
to the bottom of the StringPin Controller. This board also provides protection against electrical
surges entering the controller through the low voltage cabling.
(2) CPU PCB - This board gathers switch information and sends out solenoid voltage to each
pinsetter through the I/O PCB. Communication to the scoring system is also handled by the
CPU.
