MAXIMUM CONNECTION OF NETWORK SEGMENT
„ „
Network segment : divided network by signal amplifier
„ z
In the following case, signal amplifier is required. ●
(1) When the total length of the transmission line exceeds 500 m.
(2) When the number of total unit*1 exceed over 64 units.
When a signal amplifier is installed, network is divided into two network segments. ●
Network segments mean divided block which has been connected with signal amplifier
within above condition.
In a network segment(NS), divided by a signal amplifier, have to keep the following limitation.
Segment inside Limitation
Transmission line 500m or less
Number of unit *1 64 or less
Terminal resistor 1
Total number of control unit *2 2
*1: Unit means indoor unit, outdoor unit, signal amplifier, Touch panel controller,
System controller and so on.
*2: Control unit means Touch panel controller and System controller.
Caution
„ z
VRF network system should satisfy both of number of unit and wiring length.
When system exceeds either number of unit or wiring length, system should be devided.
