Maximum Network Length (Maximum Trunk Length)
The maximum network length is the longest distance either between terminating resistors or between the two most distant nodes on the network.
The maximum network length is determined by the type of cable and the baud rate.
| Baud Rates | Max. Network Length | |
|---|---|---|
| Thick Cable | Thin Cable | |
| 500 kbps | 100 m | 100 m |
| 250 kbps | 250 m | 100 m |
| 125 kbps | 500 m | 100 m |
Both Thick Cable and Thin Cable can be combined and used for trunk lines. In this case, the maximum network length is calculated using the following formulas.
| Baud Rates | Max. Network Length |
|---|---|
| 500 kbps | Thick Cable Length + Thin Cable Length ≦ 100 m |
| 250 kbps | Thick Cable Length + 2.5 × Thin Cable Length ≦ 250 m |
| 125 kbps | Thick Cable Length + 5.0 × Thin Cable Length ≦ 500 m |
