2. SPIKE SYSTEM AND NODE GUIDE
2.1 SPIKE SYSTEM OVERVIEW
The SPIKE Pinball system is a rugged, distributed, and
embeddedplatformcustom-designedfortherigorsofthepinball
machineenvironment.SPIKEtakesadvantageofmodern
technologies to deliver an immersive pinball experience that
supportsmodernfeatures,reducescabling,andincreases
serviceability and reliability.
A Stern Pinball machine based on the SPIKE system will have at
least one node networked together with the SPIKE node bus. The

• Lightandswitchnode(32Switch+LEDNode)-Switchand
low-power LED outputs. Contains as many 32 switch inputs
and light outputs.
• Node extensions - These LED boards add additional low-

are connected with simple serial bus.
2.2 NODE BUS CABLING
TheSPIKEnodebusutilizesstandardEthernet-styleRJ45
8-pin modular jacks and ethernet cabling. SPIKE nodes are not
compatible with standard computer networking equipment.
CAUTION: Plugging a SPIKE Node or CPU board into a standard
Ethernet port may damage one or both devices and void your
warranty.
2.3 SYSTEM POWER
TheSPIKESystemispoweredfroman48VDCswitchingpower
supply. Each SPIKE node converts this voltage to lower voltages
requiredbythenodeanditsspeciccomponents.ASPIKEnode
controls high-power outputs such as game coils and some LEDs.
These nodes are supplied directly with 48V system power. Other
nodes are low-power boards that read switch inputs and output
to standard-brightness LEDs.
