The latest IP Link-configurable control processors from Extron Electronics, the IPCP 505 and IPCP 305, are designed to support larger configurable control systems. These control processors integrate Ethernet connectivity into AV systems, giving users the ability to remotely control, monitor, and troubleshoot AV equipment, including display devices and switchers. With a high-performance embedded web server, multiple bidirectional serial ports, relays, flex I/O ports, including Ethernet and an eBus port, these control processors are ideal for applications that require control for multiple devices within a large-scale AV system. The IPCP 505 and IPCP 305 are configured with the free, easy-to-use Global Configurator software. Using free GlobalViewer web-based AV resource management and remote control application, users can manage, monitor, and control both Extron and third-party equipment such as projectors, displays, computer monitors, VCRs, and DVD players.
With a 3.5in. diagonal color LCD touchscreen and Power over Ethernet capability, the Flex-LT200 self-contained control system from FSR can mount into a wall or operate from a desktop. The unit offers four serial and four IR ports, a built-in clock with event scheduler, and multicommand scripting conditionality. The Flex-Able configuration utility provides a simple drag-and-drop environment with an extensive IR library and IR learning capability. There is also a library of serial drivers and the capability to enter serial commands in ASCII or hex. The I/O ports are on screw terminals and handle up to 24VDC. The 12VDC 500mA power supply is included, and it is also connected on screw terminals.
The heart of the VSA-51 digital AV room control system from Hall Research is the VSA-51-R central receiver in which embedded software runs and is served via HTTP to any PC, Mac, iPhone, iPad, or Android device. The system includes an inactivity timer and panel lockout, and one-time or recurring tasks may be internally scheduled. Other system components include a series of wall plates for input and output signals in various formats and a 2-gang hard button control panel and an eight-button user interface extension panel. Control connections are made through serial, IR, or contact closure, and the system allows audio level control through a 40W amplifier.
High Resolution Systems uses an interesting approach with the Universal Device Controller UDC 400, a device that can work along with a PC running Windows, an iPad, iPhone, Android, or any other device with a browser and network connection. With serial or IP conveyance, the UDC 400 can have any command for a wide range of devices assigned to any of its 40 buttons through a USB connection to the computer running the software. In addition to IP and serial protocols, the unit can operate contact closures and general purpose I/O (GPIO), tally, and relays. It also offers protocol translation for P-Bus, Art-Net, MIDI, DMX, and others. Users can select control commands for popular devices or enter their own commands through the software.
