20. Energy Saving (Command: j q)
To control the energy saving function.
Transmission [ j ][q][ ][Set ID][ ][Data][Cr]
Data 00: off
01: Minimum
02: Medium
03: Maximum
04: Auto/Intelligent sensor (depending on model)
05: Screen off
Acknowledgement [q][ ][Set ID][ ][OK/NG][Data][x]
21. Auto Configuration (Command: j u)
To adjust picture position and minimize image shaking
automatically. Auto configuration only works in RGB-PC
mode.

22. Channel Tuning (Command: m a)
To tune channel to following physical/major/minor
number.

[ ][Data02][ ][Data03][ ][Data04][ ][Data05][Cr]
Digital channels have a Physical, Major, and Minor
channel number. The Physical number is the actual
digital channel number, the Major is the number that the
channel should be mapped to, and the Minor is the sub-
channel. Since the ATSC tuner automatically maps the
channel to the Major number, the Physical number is not
required when sending a command.
Data 00: Physical Channel Number
NTSC air: 02~45, NTSC cable: 01, 0E~7D
ATSC air: 01~45, ATSC cable: 01~87
Data 01 & 02: Major Channel Number
Data 01: High byte Data 02: Low byte
Two bytes are available for the Major and Minor,
normally only the second byte is used.
Data 03 & 04: Minor Channel Number
Not needed for NTSC.
The table above lists the binary code which must be
converted to Hexadecimal before sending. For example:
The binary code to tune the sub source to an NTSC cable
channel is "1000 0001", which translates to "81" in
Hex.
* 7th bit : For which source do you want to change
the channel.
* 6th bit: Use a two part or one part channel. Most
cases just use 0 since it's ignored when using
NTSC.
* 5th bit: Use 0 with NTSC since it can only use
the physical channel number. Normally use 1 for
ATSC since most times it doesn't matter what the
physical number is.
* 4th bit: Set to 0.
* 3-0 bits: Choose signal type.
* Tune Command Examples:
1. Tune to the analog (NTSC) cable channel 35.
Data 00 = Physical of 35 = 23
Data 01 & 02 = No Major = 00 00
EXTERNAL CONTROL DEVICE SETUP
Data 03 & 04 = No Minor = 00 00
Data 05 = 0000 0001 in binary = 01
Total = ma 00 23 00 00 00 00 01
2. Tune to the digital (ATSC) local channel 30-3.
Data 00 = Don't know Physical = 00
Data 01 & 02 = Major is 30 = 00 1E
Data 03 & 04 = Minor is 3 = 00 03
Data 05 = 0010 0010 in binary = 22
Total = ma 00 00 00 1E 00 03 22
* Use the feature depending on your model.
23. Channel Add/Del (Command: m b)
To add and delete the channels.
Transmission [m][b][ ][Set ID][ ][Data][Cr]
Data 00: Channel Delete Data 01: Channel Add
Acknowledgement [b][ ][Set ID][ ][OK/NG][Data][x]
24. Key (Command: m c)

When TV is in the standby mode, TV will turn on by
POWER button of remote control only.
25. Backlight (Command: m g)
To adjust screen backlight.
Transmission [m][g][ ][Set ID][ ][Data][Cr]
Data Min:00 ~ Max:64 (*transmit by Hexadecimal code)
*Refer to "Real data mapping".
