What type of connection does a dotted line signify in a TPC schematic?

In TPC schematics, a dotted line typically signifies a less critical or virtual connection, such as a control or signal line. This distinction is important because it indicates that the connection is not meant to carry power or provide a direct physical link, but rather serves as a signal path that can influence operations like control signals, feedback paths, or communication lines. Such a connection might convey information or commands without being a hardwired, permanent path, highlighting its role in signaling rather than direct current flow or physical connection.

Understanding the function of dotted lines helps in interpreting the schematic accurately, ensuring that the user recognizes which connections are essential for power and grounding versus those that pertain primarily to device communication and control.
