Teaching and sending IR signals
The KNX IR linker can only be operated via the KNX bus or by an IR signal, as shown in
the area
ERROR! Reference source not found.
This section describes the following examples:
1.
how an IR signal is taught into the KNX IR linker,
2.
an IR signal can be transmitted via a KNX command and
3.
how a KNX object is triggered by a learned IR signal.
It is assumed that the KNX IR linker is set up as described in chapter 7 and is functional.

Teaching and storing an IR signal
This procedure applies to both scene modules IR to KNX and KNX to IR.
Figure 4: Scheme for the teach-in of an IR signal
1. The user sends the KNX command to activate the teach-in process via the KNX bus.
For this purpose, the scene building block (communication object 1 or 2) is addressed
with the corresponding storage location number. The operating mode is "learn".
2. As soon as the KNX IR linker has received the command, the Receive LED is lit. Thus,
the KNX IR linker signals that it is in the learn state and waits for an IR signal for 30
seconds.
3. Within 30 seconds the user sends an IR signal which he wants to store on the desired
scene
to the KNX IR linker. If a valid IR signal is not received within 30 seconds, the
Receive LED goes out and the KNX IR Linker returns to normal operating mode.
4. The received IR Signal is stored by the KNX IR linker and the Receive LED flashes for a
short time.
5. The Receive LED goes out and the KNX IR Linker is back in normal operating mode.
