The AV4 control processor anchors modern enterprise and residential automation networks by processing multi-device commands through a dedicated multicore engine. When integrators deploy complex audio, video, lighting, and environmental systems, they rely on centralized hardware that handles heavy concurrent loads without performance degradation. Understanding how this hardware operates helps system architects design reliable, scalable control infrastructures.
Core Hardware Architecture
At the heart of the processor sits a 4-Series multicore CPU paired with 2 GB of SDRAM and 8 GB of flash memory. This configuration delivers a substantial performance increase over older 3-Series units, allowing the unit to process high-volume automation commands concurrently.
The physical chassis includes a modular programming architecture that runs up to ten independent programs simultaneously. Programmers isolate specific functions—such as lighting control or audio routing—so that updates to one subsystem don't disrupt unrelated operations.
Processor Specifications Overview
- CPU Engine: 4-Series multicore processor
- Memory Capacity: 2 GB SDRAM, 8 GB Flash
- Program Slots: Up to 10 independent simultaneous programs
- Expansion Options: Optional CAGE3 accessory for three control card expansion slots
Network Integration and Security
Modern automation environments demand strict network segregation to protect sensitive traffic. The unit features an isolated Control Subnet that provides a dedicated Gigabit Ethernet LAN for local device management.
An installer connects touch screens, wireless gateways, or Power over Ethernet (PoE) switches directly to the control subnet ports. The processor automatically discovers connected devices and assigns IP addresses without manual configuration overhead. Meanwhile, a separate LAN port links the entire system to the wider corporate network or internet gateway using a single IP address.
Enterprise deployments require robust security frameworks out of the box. The hardware ships with authentication enforced by default, requiring administrators to create secure credentials before accessing configuration dashboards. Support for SNMPv3 remote IT management and enterprise-class network security standards ensures compliance with strict corporate IT policies.
Onboard Control Ports and Expansion
Legacy equipment integration remains a primary hurdle in commercial retrofits. The hardware bridges this gap via a comprehensive suite of onboard control connections, including RS-232 serial ports, infrared outputs, relays, Versiport I/O channels, and Cresnet network terminals.
Integrators use Cresnet connections to link motorized window shades, environmental thermostats, and lighting dimmers directly to the ecosystem. For larger facilities requiring additional physical ports, technicians install the CAGE3 accessory card into the rear panel, expanding connectivity options without consuming extra rack space.
Deployment and Management Software
Managing multi-room AV installations across large corporate campuses requires centralized cloud tools. The processor supports XiO Cloud service platforms for mass configuration, provisioning, and real-time status monitoring. Technicians push firmware updates and troubleshoot configuration errors remotely, cutting down on physical service calls.
For sites lacking dedicated programming resources, the hardware supports AV Framework software. This web-based management tool lets technicians deploy scalable room solutions using standard browser menus rather than writing custom control code from scratch.
Frequently Asked Questions
Can the control subnet be completely isolated from the main corporate network?
Yes. For high-security installations, the entire Control Subnet isolates completely from the local network, blocking external traffic while maintaining local automation integrity.
How many independent programs can run at once?
The modular architecture supports up to ten simultaneous programs, ensuring individual subsystems run isolated from one another.
What is the purpose of the CAGE3 accessory?
The CAGE3 installs into the rear panel to provide three additional control card expansion slots, expanding physical integration capacity without requiring a larger equipment rack.
Does the system support building management protocols?
Yes. Native BACnet network support allows direct communication with third-party HVAC and security systems over standard Ethernet.
