White Balance Data (40H)

This command is used to set values 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:
1
Bits which are not specified here are undefined bits
and their values are always ignored.
1 3200 Switch
ON (3200K - 5000K) = 10
OFF (5000K - 10000K) = 01
2 User preset switch
Be sure to specify 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 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 Blue Bias Value
2 Green Bias Value
3 Red Bias Value
4 Blue Gain Value
5 Green Gain Value
6 Red Gain Value
