IR Receiver Decoder S 450
Description
The IR Receiver Decoder S 450 translates the infrared
(IR) control signals from the hand-held IR Remote
S 425 into bus telegrams. IR control signals of a pair of
buttons on the IR Remote S 425 can be evaluated for
the individual buttons or for the pair of buttons.
Individual Button Configuration
When configured for evaluation as individual buttons,
the IR control signals can be translated into bus
telegrams for the following functions:
• Switching (On, Off, Toggle)
• Single-button dimming
• Single-button solar protection control
• Bell function (press on, release off)
• 1-bit scene control
• 8-bit scene/effect control
• Sending 8-bit value (percent, 0 to 255)
• Sending 16-bit value (temperature value,
brightness, 0 to 65535)
• Forced control switching (on/inactive; off/inactive)
Depending on the selected function, after sending the
initial telegram, a second time-delayed telegram may
be sent or, alternatively, another function may be sent
on a long button press.
For example, to easily implement a time limited lighting
application, one button would be configured to send
the “Switching, On” telegram and then send a second
telegram with a 5-minute time delay for “Switching,
Off”.
Button Pairs Configuration
When configured for evaluation as a pair of buttons the
IR control signals can be translated into bus telegrams
for the following functions:
• Dual button dimming with stop telegram
• Dual button solar protection control
• Sending percent value (variable)
• Sending 8-bit value (variable)
• Forced control switching (on/off/inactive)
• 1-bit scene control
• 8-bit scene control
Depending on the selected function, after sending the
initial telegram, a second time-delayed telegram may
be sent.
The operation of each individual button may be
blocked by a communication object.
ETS (Engineering Tool Software) is used to select the
application program, assign parameters and
addresses, and transfer this data into the IR Receiver
Decoder S 450.
To transfer the physical address, a magnet is used for
contactless toggling between normal operating mode
and addressing mode. A programming LED behind the
black IR receiver lens displays the normal/addressing
mode status.
