02. Power Off
- To turn the power of the TV off, the following
string needs to be sent to the unit;
E1 : It is the start of the command and signifies
a “key” (as in front panel keys) command.
11 : It is the command for power off.
F2 : It is the checksum calculated by adding
“E1” + “11” to get “F2”.
The TV will perform the action and will not return
a response.

03. Volume Up
- To turn the volume of the TV up, the following
string needs to be sent to the unit;
E1 : It is the start of the command and signifies
a “key” (as in front panel keys) command.
0A : It is the command for volume up.
EB : It is the checksum calculated by adding
“E1” + “0A” to get “EB”.
The unit will perform the action and will not
return a response.

04. Volume Down
- To turn the volume of the TV down, the following
string needs to be sent to the unit;
E1 : It is the start of the command and signifies
a “key” (as in front panel keys) command.
0B : It is the command for volume down.
EC : It is the checksum calculated by adding
“E1” + “0B” to get “EC”.
The TV will perform the action and will not return
a response.

05. Volume Direct Access
- To set the volume of the TV to a specific level,
the following string needs to be sent to the TV;
EA : It is the start of the command and signifies
a volume command.
XX : It is the value that the TV is to be set to in
hex.
YY : It is the checksum calculated by adding the
previous bytes together and truncating.
- Valid values for “XX” are from 0-3F Hex, if the
second MSB (X1XXXXXX) is set to one, the
volume data is ignored and the TV mutes the
sound. To unmute the unit a EA command with
the second MSB set to 0 and a volume greater
than 0 should be issued.
Example;
To set the volume level to 29 decimal (about half
of the 63 decimal range), the data byte would be
constructed in binary as follows (MSB) 01011101
(LSB) or 5D hex. The command would then be:
●
EA5D47
EA : It is the start of the command and signifies
a volume command.
5D : It is the data byte to select the volume level
and to set the value to 29 decimal.
47 : It is the checksum calculated by adding
“EA” + “5D” to get “47” after truncating the
resulting “147”.
The TV will perform the action and will not return
a response.
