MAXIMUM CONNECTION OF NETWORK SEGMENT
z
Network segment : divided network by signal amplier

●
In the following case, signal amplier is required.
(1) When the total length of the transmission line exceeds 1,640 ft. (500 m)
(2) When the number of total unit*1 exceed over 64 units.

●
When a signal amplier is installed, network is divided into two network segments.
Network segments mean divided block which has been connected with signal amplier within
above condition.
In a network segment(NS), divided by a signal amplier, have to keep the following limitation.

Caution
VRF network system should keep both of number of unit and wiring length.
When system exceeds either number of unit or wiring length, system should be devided.
Di󰀨erent VRF series may not coexist within the same network.
