Goals and Symptoms
What is the maximum length of cable from HUB to one ATV 58? Is the HUB has some active elements (repeater ICs)inside? If they using all ports to ATV 58, then all network cable length can be counted or every node from HUB can be the longest 1200m (400feet)?
Causes and Fixes
There is no active elements inside LU9GC3, it's only a passive PCB. The maximum cable lenght from HUB to ATV is 40 meters but these 40 m are distributed on all ports.
Exemple : for 8 x ATV on the hub, the max lenght by ATV is 5 meters of course if the distribution is homogeneous.
As you said the max lenght for Modbus is 1200 meters, derivation included, in your case if you have only one hub it's 1200 - 40 = 1160 m.
