6.2 Connecting the Room Controller

Since the room controller is used as a slave system controller for Master Room Controllers via the proprietary communication channel K-Net(as illustrated in Figure 6):

•It requires only a K-Netconnection to the Master Room controller

•A power supply unit is not required2

•The room controller can be programmed only via the SV-552Processor/Switcher Master Room controller

1 The ground connection is sometimes connected to the shield of the RS-485 cable (in most applications, it is not connected) 2 Power supplies are sold separately. Consult your Kramer dealer for details
