NetStreams designed the Quartet Q4000 for maximum audio switching flexibility with minimum setup and configuration. Capable of routing up to nine sound sources to as many as four separate zones, the Multi-Room Processor (MRP) responds to commands from up to four wall-mounted, Cat-5-connected keypads and one IR remote. The sources can include four global devices, a central FM tuner and up to four remote units. Each keypad includes a built-in microphone for use in a multi-room intercom function with room-to-room paging and room monitoring. The Rest and Rise feature allows a source to be played for a set time after a specific delay.
The FP-ECC1 energy conservation controller from Radio Design Labs can turn on or turn off any AV system in response to a variety of conditions or on a timer delay. A system may be powered on by an external switch or in response to the presence of an audio signal. The audio trigger input has switch selectable low cut filters and level sensing controls. Audio presence sensing can also shut down a system after a time of inactivity that is adjustable for 15, 30 or 60 minutes. When user activity is sensed, the shutdown timer starts over. Force-on and force-off terminals override all timers and delays for immediate startup or shutdown. RDL offers optional remote controls that connect directly to the FP-ECC1 using twisted pair wire and RJ45 connectors.
Using bi-directional wireless Zigbee communication with compatible RTI remote controls, the XP-3 control processor stores commands and macros and features a built-in clock for time-based events through RS232, IR, Ethernet and relay control. Its multi-purpose I/O port can act as an IR sensor or it can connect to RTI accessory devices to sense equipment power status or communicate via one-way RS-232. The unit has a 128MB non-volatile flash memory, two IR output ports, two assignable voltage sense inputs, two programmable relay outputs and one two-way RS232 port for supported devices. The 10/100Base-T Ethernet port supports Power-over-Ethernet Class 3. The XP-3 also features field upgradable firmware and is programmed using the RTI Integration Designer software.
The SmartControl 25 from Savant Systems packs eight RS-232/422/485 serial ports, six IR transmitter ports, three relay ports, seven GPIO ports, and an Ethernet port, over which it can be linked and powered (SSC-P025), into a half-rack sized 1RU enclosure. The front panel includes a variety of diagnostic LED indicators and each relay port can carry a maximum of 30V DC with a maximum current of 1.0 amps. The GPIO, relay, and IR terminals use 6-pin screw down connectors while the serial ports terminate on RJ-45s.The unit operates on a separate 12VDC power supply.
SP Controls has laid out the PXE-DCM+ PixiePlus Device Control Module for maximum function in minimal space. Fitting into the box of a single gang wall switch, the PixiePlus learns IR codes from almost any remote without using a computer and stores them to control a wide range of AV devices. A single button can be programmed with multiple remote codes and the unit can power devices up/down, select sources and raise and lower volume levels. For multiple rooms, each PixiePlus can wirelessly clone its configuration to others. A series of button commands can also be programmed into the controller as a security code to prevent unauthorized operation.
The MRX-10 advanced network system controller from Universal Remote Control can operate AV devices on Ethernet, infrared, serial, relay and sensor control and communicate bi-directionally with Total Control remotes and keypads. The unit can issue single or macro listed commands and is expandable via LAN to up to eight MRX-series sub-base stations. The rear panel includes eight IR ports, four RS232, four sensor connections, two relay terminals, two 12VDC power outputs and the chassis fits in one rack space using the optional RMK-1 rackmounting kit. The MRX-10 is also compatible with the optional RFTX-1 RF transmitter and it can be programmed either locally or through an RJ-45 LAN port.
Xantech designed the 590-10 programmable controller to be flexible in configuration using 16 isolated input circuits and a learning microprocessor to control infrared devices by using simple contact closure triggers. Programmed with Universal Dragon Drop-IR Program Software, the unit can incorporate up to 40 commands for each key, button or contact closure that is connected to it on a series of screw terminals. The nine-pin COM port is used for a computer connection in programming. IR codes can be learned from the original equipment remotes or downloaded from an online library.
