Defines the RGB Mode selection for the monitor.
The values are specified as follows:
1 2
1 Video signal when using the OPTION 1 input
connector
RGB = 01
COMPONENT = 10
2 Sync signal when using the OPTION 1 input
connector
Internal = 01
External = 10
3 Video signal when using the RGB/
COMPONENT input connector
RGB = 01
COMPONENT = 10
4 Sync signal when using the RGB/
COMPONENT input connector
Internal = 01
External = 10

White Balance Data (40H)

This command is used to store values set for the white
balance data into the volatile RAM of the monitor.
The command has three components:
1. Range of color temperature values to be saved
2. The Elements of White Balance data being sent
3. The White Balance values to be saved
Each of these elements is described below
1. Range of color temperature values to be saved is
the first byte of the data within the command block
of the message.
The values are specified as follows:
Bits which are not specified here are undefined bits
and their values are always ignored.
1 User preset switch
Be sure to specify 1.
8
3 4
1
(always 1)
2. The Elements of White Balance data being sent is
the second byte of data contained within the
command block of the message.
Several items of white balance 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 NAK is issued by the monitor.
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 Blue Bias Value
2 Green Bias Value
3 Red Bias Value
4 Blue Gain Value
5 Green Gain Value
6 Red Gain Value
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 NAK is issued
by the monitor.
The values are specified as follows:
White balance value
Bits which are not specified here are undefined bits
and their values are always ignored.
