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
