Terminating resistor
What is Terminating resistor?
Resistor at the end of a bus line that absorbs the signal instead of letting it reflect. A bus needs exactly two of them, one at each end of the line.
What matters about Terminating resistor in practice?
Not one per device, not one per network, not three to be safe. Both versions, male and female, are already included with the system monitors.
The tricky thing about a termination fault is that it does not cause a total failure: a bus with only one terminator usually works and drops out occasionally, preferably with long lines, many nodes or when a heavy load switches.
