DIFFERENCE:
This feature is available only in UMX-HDMI-140-
Plus model.
UMX-HDMI-140-Plus model can analyze and store the received
serial data. For more information see RS-232 Recognizer
Put a tick to Enable message recognizer on this port to switch the
recognizer on.
Delimiter sequence text box is for set the delimiter string in hex
format. When this string is detected in the incoming serial data,
the device saves the RS-232 message data from the first bit, until
the delimiter (or the data between the two delimiters).
INFO:
0D0A is the factory default value, this is the hexadecimal
code of Carriage Return and Line Feed. LW3 protocol commands
ended with this formula, so the default value support the
recognition of the LW3 commands and the stored changes
automatically.
If the Timeout is enabled and set, the received data is saved when
the timeout is elapsed after the last received message.
In Received messages box shows the last received and stored
message in Text (RECOGNIZER.Rx), Hex (RECOGNIZER.RxHex),
and Hash (RECOGNIZER.Hash) format. The Hex and Hash contains the delimiter.
Press the Clear button to erase this storage.
Clicking on Reload restores the Factory Default Settings

INFO: Message recognizer operates independently of the RS-232 mode.
Configuration Example for the Message Recognizer
The detailed description below shows how to configure the message recognizer in
Example.
When the UMX-HDMI-140-Plus has an active video signal, the switcher login the VC codec automatically.
The signal presence triggers a bi-directional communication with the VC codec via RS-232:
Step 1. Turn on the recognizer: Enable it on the P1 serial port.
Step 2. Set the delimiter (in hex format). In this case, the
delimiter character is ':', which is '3a' in hex format.
When the delimiter string is detected in the incoming
serial data, the serial message is stored in string (in Rx
and ActiveRx property), hex (in RxHex and ActiveHex
property) and hash (in Hash and ActiveHash property) format. These stored content can be set as a
condition in the event manager.
