Serial Fiber Optic Interfaces

Termination

Both ends of a Profibus segment must be terminated with a

terminating network which is usually integrated into the

Profibus connectors and can be optionally switched. This

resistor network has two functions: to ensure reflection-free

termination of the line, and to provide a defined rest state on

the lines during the high-impedence phases of the bus system.

To supply the termination network, Pin 6 provides 5 V

referenced to the ground Pin 5, with a maximum load capacity

of 50 mA.
