Note
●
If an incorrect command is sent, this unit will reply an
“ER401” command to the computer.
●
If communication has not been established for
reasons such as a bad connection between the
computer and TV, nothing is returned (not even
ER401).
●
“ER401” may be returned when a command cannot
be received correctly due to interference from the
surrounding environment.
Please ensure that the system or software resends
the command if this occurs.
Communication interval
After getting the feedback, then you can continue the
following commands.
Suggest setting a timeout for the command response.
(specify 10 seconds or longer)
If multiple commands are transmitted, be sure to wait
for the response for the first command to come from
this unit before sending the next command.
●
When sending a command which does not require
parameter, a colon (:) is not needed.
