AV Control Systems

Perhaps traditionally known for the products involving separate processors and touchpanels, Crestron has more recently introduced the MPC series featuring an integrated AV control processor and hard-button user interface. The MPC-M50 mounts in a three-gang wall box and provides 16 programmable buttons along with a programmable green LCD dot-matrix front panel at 128x64 resolution. The panel also features LED indicators and customizable back lighting for the buttons, a hardware volume control knob, and wireless remote operation. With Ethernet connectivity, the unit also presents a web interface for remote configuration and control using e-Control 2 Xpanel technology and an interface to other Crestron systems including RoomView, Crestron¡¯s systemwide AV control and management software application. The Cresnet slave mode allows the panel to become part of a larger Crestron system, and the built-in light sensor can be programmed to control the brightness of its own backlighting or connect to control external devices based on ambient light levels.
With Ethernet capability, the ipCUE-gamma AV system controller from Cue USA packs a variety of control interfaces into a small control interface less than 4.5in. wide. There are bidirectional RS-232 and RS-485 serial ports, infrared outputs, and general I/O ports that can be configured as analog inputs, digital outputs, or as 24V relay contacts. The status of all control ports, power, CUEnet, and CPU is indicated through LEDs on the front panel. Scheduling operations are based on an internal realtime clock, and the unit is equipped with the company¡¯s 4-pin CUEwire port for interfacing with any of the Cue button panels and touchpanels. The internal web server allows remote configuration and control through any web browser, and the page configuration can be customized with any Flash or HTML editor. The ipCUE-gamma has an internal 16MB RAM and an internal 16MB flash memory.
One of Extron Electronics' newest products has allowed the company to cross into the touchpanel market. The new line of TouchLink touchpanels can operate with the IPL 250 IP Link Ethernet control processor. It has three bidirectional serial control ports, four carrier or non-carrier infrared ports, four 24V 1-amp relay ports, and four contact closure inputs. The programming can be set up with version three of Extron¡¯s Global Configurator software application or Extron¡¯s Simple Instruction Set (SIS) commands, and the internal web server can support up to 200 simultaneous sessions with its 7.25MB of nonvolatile user memory. The unit is set up for display devices using Extron¡¯s library of device driver downloads in the same way that all the other IPL series controllers are configured. All wiring connections other than the Ethernet port are made on standard Phoenix captive-screw terminals.
The FSR RN-1000 room controller features four serial ports, four IR ports with an IR learning function, and four dry contact closures. It can be operated locally with the front-panel controls, or it can be run remotely on either an RS-232 connection from FSR¡¯s wall plates or through an IP connection to its internal web server using any web browser. The basic wall plate fits a one-gang wall box and offers a volume control, audio and projector mute, source selection, and six user-programmable buttons. The advanced wall plate fits a two-gang wall box and provides six more programmable buttons, transport controls, and menu navigation keys. The front panel has LED indicators for power, infrared activation, device status, and the status of all four relay ports. In addition to the device control ports, the rear panel includes an RS-232 serial port and an Ethernet RJ-45 connector.
Consisting of a wall plate controller/sender, a connector panel, and a separate receiver all connected by Cat-5 cables, the VSA-32 AV switching and control system from Hall Research is designed for very simple installation. The wall unit and remote receiver may be located up to 750ft. apart. The control surface, in a two-gang wall plate, has three source-selection buttons, a power control button, a volume knob with sound level indicator, and a selector button to switch the volume control between AV sources and the microphone. The connector panel has video/audio ports for each source-selection button along with an XLR microphone input. The input channels include two VGA and one composite/S-Video input while the remote unit includes a built-in stereo power amplifier capable of driving a pair of 4§Ù or 8§Ù loudspeakers.
