[Developing AV Solutions]Assuming that the screen and projector are both Ethernet controllable devices, where does the control system for the AV…

The question specifies that the devices are "Ethernet controllable," meaning they are controlled via commands sent over an IP network. For the control system to send commands and the devices to receive them, both the controller and the controlled devices must be connected to the same logical network. This network connectivity is the fundamental requirement for operation, regardless of the system's physical location. The physical placement in a rack or specific room is an implementation detail, not a prerequisite for functionality. CertEmpire.com

Chapter 5: Creating AV Solutions, "Control Systems" section: This chapter details how modern

control systems operate, emphasizing the shift to IP-based (Ethernet) control. It explains that for

IP control, the control processor sends commands over the network to the IP address of the

device being controlled, establishing that network connectivity is essential.

Chapter 1: Computer Networks and the Internet: This foundational text establishes that for any

two hosts (e.g., a control system and a projector) to communicate over the internet or a local IP

network, they must both be connected to that network. This is a core principle of all network

communication.

and Coordination Process.

This standard outlines the design process for AV systems. While it discusses equipment location

in racks and rooms for logistical and environmental reasons, it implicitly separates these physical

considerations from the logical network topology required for device communication and control.

The logical connection (network) must exist before the physical location is finalized.
