RM-433 RF Receiver

Description

The RM-433 is a radio frequency receiving device that operates at 433MhZ. It is designed to receive signals that are transmitted by RTI universal system controllers.

The RM-433 contains a microprocessor that monitors all received signals so that RF noise and data from non-RTI transmitters is filtered out. When valid RTI data is detected, the RM-433 passes the signal through its output driver which allows the data to travel long distances over wire. The output driver is compatible with industry standard infrared repeating systems*, and can be wired together with those systems or with additional RM-433 units. This allows RTI control systems to be controlled from almost any location with either IR or RF transmitters.

* The RM-433 does not directly control A/V components - it is for communicating trigger codes to RTI control processors only. Use of second party infrared repeater systems may be used between the RM-433 and RTI control processor as a path for the RTI trigger code only. A 433MHz remote control must be used with this model of antenna. It is not compatible with the 2.4 GHz Zigbee® enabled remote controls.

RM-433 RF Receiver

Product form

  • Reliable RF reception due to matched antenna, connector, and PCB.
  • Modular design that allows multiple RM-433 units to be wired together. This allows for any desired coverage area.
  • Output signal is compatible with industry standard infrared repeating systems. This allows multiple IR and/or RF receivers to be wired together into an RTI control system.
  • No dedicated power supply required. Power is derived directly from the RTI control system.
  • A feedback LED confirms operation.
  • Available only to professional system integrators.
