RM-433
It’s Under Control®
The RM-433 is a radio frequency receiving device that operates at 433MhZ. It is designed to
receive signals that are transmitted by RTI remote controls.
The RM-433 contains a microprocessor that monitors all received signals so that RF noise and data
from non-RTI transmitters is ltered 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 provides superior quality and reliability as well as these specic features:
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.congured in
“repeater” mode.
No dedicated power supply required. Power is derived directly from the RTI control system.
A feedback LED conrms operation.

harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment o and on, the
user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the receiver.
Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received including interference that may cause undesired operation.
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received including interference that may cause undesired operation.
Cet appareil est conforme avec Industrie Canada exempts de licence standard RSS (s). Son fonctionnement est soumis aux deux conditions
suivantes:
1. Ce dispositif ne peut causer des interférences nuisibles.
2. Cet appareil doit accepter toute interférence reçue y compris des interférences qui peuvent provoquer un fonctionnement indésirable.

If you are having problems with your RM-433 please read these troubleshooting tips before contacting technical support.
The Data LED is constantly ashing red
• This does not necessarily indicate a problem that will eect performance. If it does, move the RM-433 to a dierent
area.
The Data LED never turns green
• Make sure the RM-433 is wired correctly to the central control system, and verify the control system is powered-up.
• Make sure the RTI universal system controller is programmed to output RF data.
The Data LED turns green when it receives a command, but the control system does not respond
• Make sure the Signal terminal on the RM-433 is wired to the Signal In terminal on the central control system. The
Signal In LED on the control system should illuminate.
• If there is also an infrared repeater connected to the control system, make sure it is not injecting noise onto the
signal line.
• Make sure the programming in the central control system matches the universal system controller.
Troubleshooting
The RM-433 is designed to operate with an RTI universal system controller and central control system. It receives RF
data that was transmitted by the universal system controller, converts it to an electrical signal, and transfers it to the
central control system using 3-conductor wire. Power is derived from the control system, and no programming or setup is
required.
While power is applied to the RM-433, it will constantly monitor the air for signals modulated at 433MhZ. The Data
feedback LED indicates the presence of these signals:
DATA LED
O = No 433MhZ signal detected
Red = Noise or invalid data detected
Green = Valid data detected
Whenever the Data LED is green the RM-433 is sending the received data through its output driver. If the Data LED is o
or red, the output driver is shut o. This prevents noise that is being received by one RM-433 from interfering with valid
data that is being output by another RM-433 (if they are wired together to the same control system).
