8.4.2 Error response to invalid messages
The UE410-EN will set the most significant bit of the command word in the event that an
invalid or improperly formatted message is received.

Command WORD Bit 15 of received command will be set.
(i.e. Command of 00F2hex would become 80F2hex.)
Following data (Length de-
termined by

Unchanged. Returned as it was received.
8.4.3 Auto Update Mode
The UE410-EN can be configured to automatically update the data set information (e.g.
the application does not need to send any request messages as it would do in polling
mode, see section 8.4.4 for details) once the connection to the application has been made.
The configuration settings are available via the UE410-EN Web Server or via the TCP/IP
interface itself. Using one interface does not disable the other: The Auto Update Mode
could be enabled via web server and disabled via TCP/IP command, for example.
