DESCRIPTION
The R.F. Solutions Remote telemetry link provides a reliable one channel switching link that can be used for
many telemetry applications. Designed to save the cost or hard wiring, the system is easy to install with screw
terminal provided at both ends.
Design to replace a simple wired switch the transmitter can receive a switch input with the receiver unit
providing relay outputs rated at 10A @ 240Vac.
Operation is simple, when a valid input signal is detected on the transmitter input, an encrypted message is
sent to the receiver which reads the message and operates the relevant output. The system is highly secure
using one in 10,000 billion possible encrypted codes.
The system is made reliable by the automatic watchdog signal sent intermittently by the transmitter. If the
watchdog signal is not received by the receiver within 24hours then an LED indicates that the link has been
lost. An additional ”Low battery” LED is also provided to indicate that the transmitter battery voltage is low.
Minimal configuration is required, once set to ‘learn’ mode, the receiver stores the transmitter identity code in
non-volatile memory (remembers the code even when the power is removed) and the system is ready to
operate. The receiver has the capacity to learn up to 50 transmitters identity thus enabling one to many and
many to one transmitters and receivers

RECEIVER
CONNECTION LOST FEATURE
The transmitter will automatically transmit a signal to the receiver once every 24 hours. If the receiver
does not receive this signal then the “Transmitter Connection Lost” LED will illuminate. This will
continue to operate until the receiver receives a valid transmission from the transmitter. If the receiver
has been taught more than one transmitter then this feature is disabled.
LOW BATTERY
The low battery feature informs the user that the transmitter used has a low voltage battery.
The “Transmitter Battery Low” LED illuminates if the receiver has received a transmitted signal with low
voltage signal present. This will continue to operate until a transmitted signal without the low voltage
signal has been received. If the receiver has been taught more than one transmitter then this feature is
disabled.

Press the programming switch on the receiver once (SW1)
The learn LED will illuminate
Make the switch input on the transmitter once, learn LED on the receiver will extinguish
Make the switch input on the transmitter again, learn LED will flash
When the learn LED has stopped flashing this transmitter will now operate the system

ERASING TRANSMITTER(S) FROM MEMORY
1. To completely erase all transmitter, press SW1 on the receiver for 10 seconds.
2. The learn LED will turn off after the 10 seconds to indicate the transmitter(s) have been erased
Note : Individual transmitters can not be erased.
