Device taps provide points of attachment to the trunk line. Devices can be connected
to the network either directly to the tap or with a drop line. Taps also provide easy
removal of a device without disrupting the network operation.

Power Taps
A power tap connects the power supply to the trunk line. Power taps are different
from device taps and they can have the following specifications:
•
A Schottky Diode, which connects to the power supply V+, allows multiple
power supply connections (this eliminates the need for custom power supplies).
For more information about the Schottky Diode, refer to
.
•
Two fuses or circuit breakers to protect the bus from excess electric current,
which could damage the cable and connectors.
When a power tap is connected to the network, it can provide the following:
•
A continuous connection for the signal, drain, and V- wires.
•
Electric current limiting in each direction from the tap.
