This is a Master Controller for Universal Remote Controls. It was professionally installed new in our media room closet 3 years ago. There are no dents or scratches, looks brand new, and is in good working condition. It comes with a RFX-250 sensor that expands the range. I'm a customer, so I don't understand all the technical details, so I have copied this description from another website. The listing also includes 1 Genesis MX900 remote controller ($250). From what I understand, you have to be a dealer to download the programming software but we loved the remote and the capabilities it could handle.
"High performance audio video systems can include IR (infrared controlled devices such as Satellite and Cable set top boxes, DVD players etc.),RS-232 (serial controlled devices such as projectors, surround soundreceivers and media servers), and Relay and Voltage controlleddevices (such as lights, drapes, curtains and blinds).The MSC-400Master System Controller is designed to seamlessly automate allof these types of devices. Installation of the MSC-400 insures thatany future purchase can be successfully integrated regardlessof its control method.
In the MSC-400 System,there are four compatible remotecontrols which can be programmed to interface with theMaster System Controller; the MX-3000, MX-950,TX-1000 and the MX-900.All have unique options for cus-tomization to any client’s tastes and needs, up to a uniquegraphical style for every room and every user."Special: Advanced ARM7TDMI microprocessor enables the MSC-400 to perform sophisticated logic, with nested IF ELSE statements and tests of sensors and variables.
Size: 17.25" x 8.5" x 2.5"
Weight: 77.6 oz.
Learning Capabilities: Standard frequencies (15kHz to 460kHz)
Macro Capabilities: Supports up to 32,640 macros of 255 steps in each macro. Since Macros can be nested as one step inside another Macro, there is no realistic limit for macro steps.
Memory: 32 Megabytes of SDRAM and 64 Megabytes of NAND Flash Memory enable the MSC-400 to support vast, complex configurations.
RF Freq: 418 or 433 MHZ (Narrow Band)
Range: 50 to 100 feet, depending upon the environment
