Extended Star Wiring
Correct Example
The following is an example of a correct wiring configuration:
•
Master station number 1 is located within 10 metres of the star
centre.
•
Each branch longer than 10 metres is terminated with 200 ohms.
•
The number of branches is not more than 9.
•
At least two branches are longer than 10 metres.
•
No branch is over 150 metres in length.
•
The sum of the distance of all branches is:
6 + 40+ 5 + 70 + 70 + 100 + 80 + 20 = 391 metres (less than 400
metres)
•
Two units are connected on a branch (only one unit terminated).
•
There are less than 4 units within 10 metres of the star centre.
