  • Page 37: Communications

    See Figure 2-10 The multicast signals from the 7500NB matrices are routed through a managed Ethernet switch. Using the software and instructions that come with the managed Ethernet switch, Virtual Local Area Networks (VLANs) can be created to manage the communication between matrices, the Encore Control Frame, and other equipment connected to the switch.
  • Page 38 Section 2 — Installation Figure 2-11 shows the Ethernet requirements for a 7500NB 512x512 that is controlled by a Series 7000 Control System. Dedicated Ethernet Switches are used to communicate between the matrices. One Ethernet Switch is required for each set of up to four matrices. The switches do not have to be in the same rack as the matrices and the standard cable length restrictions of 100 m (328 ft) apply.
