4. Device Concept
4.3.2. RS-232 Recognizer
This tool is able to recognize and store the incoming RS-232 message until the previously defined string
(delimiter) is arrived or the timeout elapsed after the last data. The last incoming serial data is stored and it
can trigger an action in Event Manager.
ATTENTION! The recognizer function works, when the operation mode of the RS-232 port is control or
command injection (in this case, one of the Ethernet socket have to be opened). For more details about
the operation modes see Serial Interface
RS-232 Recognizer Example
The lamp can be turned on and off with the light switch and the RAP-B511. When the lamp turned off by the
switch, the relay box sends an RS-232 status message to the RAP-B511 to inform, and that the lamp was
turned off. When the lamp is controlled with RAP-B511 next time, the device sends the 'turn on' command to
the relay box of the lamp. This example shows how to syncronize the same control function in the RAP with
an other device.
