Preset Data (41H); Preset Data - Sony Trinitron PVM-14M2MDU Interface Manual

3. The White Balance values to be stored
Each value requires two bytes of data, the first byte
of the pairing is the Most Significant byte.
The pairs of bytes start at the Least Significant Bit
end of the elements of data being sent i.e. if the
data to be saved is blue gain and red bias then the
first pair of white balance value bytes is blue gain
and the last pair is red bias.
If there are not enough or too many data bytes of
white balance data to be saved then no values are
changed and the message is effectively ignored.
The values are specified as follows:
White balance value
Bits which are not specified here are undefined bits
and their values are always ignored.

Preset Data (41H)

This command is used to set values for the Preset data
into the volatile RAM of the monitor.
The values changed by this command will be lost
when the controlled monitor is switched from remote
to local unless they are saved in the NV RAM. The
settings of the front panel controls will be ignored
while the monitor is controlled via this protocol.
The Preset data consists of Chroma, Phase,
Brightness, Contrast, Aperture and Volume.
The command has three components:
1. User setting switch
2. The Elements of Preset data being sent
3. The Preset Values to be saved
Each of these elements is described below.
1. Be sure to set (1) the least significant bit of the first
byte of the data within the command block of the
message.
Bits other than the LSB are undefined bits and
their values are always ignored.
User setting switch
(always 1)
2. The Elements of Preset data being sent is the
second byte of data contained within the command
block of the message.
Several items of Preset data can be specified in one
message stream. Only those elements that need to
be changed are indicated in this byte.
The values of data being sent are indicated by a 1
being set in the appropriate bit position. Otherwise
a 0 in the bit position indicates no data to be
changed.
If the value is zero no values are changed and the
message is basically ignored.
The values are specified as follows:
1 2 3
Bits which are not specified here are undefined bits
and their values are always ignored.
1 Volume
2 Contrast
3 Aperture
4 Brightness
5 Phase
6 Chroma
3. The Preset values to be saved
Each value requires two bytes of data, the first byte
of the pairing is the Most Significant byte.
The pairs of bytes start at the Least Significant Bit
end of the elements of data being sent i.e. if the
data to be saved is Phase and Contrast then the first
pair of Preset value bytes is Phase and the last pair
is Contrast.
If there are not enough or too many data bytes of
Preset values to be saved then no values are
changed and the message is effectively ignored.
The values are specified as follows:
Preset data value
Bits which are not specified here are undefined bits
and their values are always ignored.
