5. Examples
1. Send the simulated "SWITCH ON FROM STAND-BY AND SELECT SOURCE" Remote Control
keycode.
Remote Control allows Switching on from Stand-by via one of the keys "1", "2" ... "11", "12".
Send, for instance, the code relative to key "1":
BEEF02060080E5490100000000.
The HTL40 switches on and selects Input 1.
The HTL40 returns the response code: 06 (Acknowledged with no error).
NOTE: Commands that simulate keys "1", "2" ... "6" switch on the unit and select the corresponding
Source.
Command that simulate key "0" switches on the unit: the last source memorised prior to switch off is
automatically selected.
2. Send the simulated "MENU RIGHT" Remote Control keycode.
Send the packet:
BEEF02060023E75A0100000000.
The OnScreen Display appers on the screen.
The HTL40 returns the response code: 06 (Acknowledged with no error).
3. Send the "SET ASPECT ANAMORPHIC" Operation Code.
Send the packet:
BEEF0206009DF5840100000000.
The Aspect Ratio changes to Anamorphic.
The HTL40 returns the response code: 06 (Acknowledged with no error).
4. Select "INPUT 3 (COMP RGB 1) WITH YcrCb 15kHz SIGNAL"
Send the packet:
BEEF0319005B0C01820800000000000008000000000000000000000000000000
Wait for the return code and add an additional delay of 50 ms.
Send the the code relative to the Key to which Input 5 has been assigned: for instance if the key is "3"
the code is:
BEEF02060062E44B0100000000
6. Warnings
When the number of bytes sent to HTL40 is greater than indicated for the Command (32 bytes for Operation
Packets and 13 bytes for Event Packets), excess data will be ignored.
Conversely, if number of bytes sent to HTL40 is smaller than required by the Communication Protocol, the
command may be ignored.
Command execution time may vary from few milliseconds to 500 milliseconds, depending on the operation
that have been requested.
If the unit is busy when a command is sent, the unit may not accept the command. If several commands are
to be sent one after the other, sufficient time between them should be allowed.
