Each board has 2 separate banks of 8 switch inputs. Each input is pulled up to 12V and detects a switch state change when the input drops below 6V. Switch inputs can therefore be connected directly to:
- Mechanical switches
- Opto receivers
- Hall effect sensors
- … and many other sensor devices
SW-16 boards can be chained together over the 2-wire serial bus to extend the number of switch inputs in the system. Each SW-16 board has a set of dipswitches for uniquely identifying its address on the bus. The P3-ROC has built-in support for 16 SW-16 boards, representing 256 switch inputs.
Note – The P3-ROC is the only PinballControllers.com product that natively connects to one or more SW-16 boards. If you’re using an original P-ROC, you’ll need to wire your switches to its dedicated switch inputs and/or its switch matrix connectors.
Also note – Version 2 SW-16 boards have a slightly different pin-out than version 1 boards and are therefore not backwards compatible. The 10-pin headers now include a 12v output on pin 1 and no longer have a key pin.
