System Overview 25
SYSTEM SIGNALS
The signals used in the Sync scoring system can be divided into 2 types; Communication / Control and
Video.
Communication/Control
Communication between components in the Sync system is handled using either an Ethernet network or
a serial communication.
Ethernet provides communication between the control desk computer(s), the Sync consoles, the Display
Controllers and the Peripheral Controller boxes. Refer to the gures titled Sync Ethernet Cabling.
Serial communication allows a Peripheral Controller to communicate with components within the
lane pair. It is equipped with an RS-232 port to allow it to talk to Vector Keypads and RS-485 serial
communication ports to allow it to “talk” GS pinsetters and Brunswick Automated Bumpers.
The Display Controllers use RS-232 to turn the overhead monitors on/off and to switch video inputs.
Refer to the gure titled Sync Lane Pair Communication Cabling.
