Command Description White Balance Data (40H) Select Caption (2EH) This command is used to set values for the white This command is only valid for the PVM-14M2MDU balance data into the volatile RAM of the monitor. and PVM-20M2MDU. The command has three components: This command defines the caption selection for the 1.
3. The White Balance values to be stored 2. The Elements of Preset data being sent is the Each value requires two bytes of data, the first byte second byte of data contained within the command of the pairing is the Most Significant byte. block of the message.
Command Description The values are specified as follows: NV RAM Save (45H) This command is used to store data into the NV RAM. The data is taken from the current volatile memory locations and stored into the NV RAM. Bits which are not specified here are undefined bits The command has three portions: and their values are always ignored.
2. The Preset Adjustment values to be used The data bytes start at the Least Significant Bit end Each value requires two bytes of data, the first byte of the elements of data being sent i.e. if the data to of the pairing is the always ignored byte.
Command Description 2. The data items to be restored are defined in the 1 Selected Offset second, third and fourth bytes of data. 2 Current Input Configuration This is the last section of data within the message The monitor will reply with the Status Reply (70H) and is used with the White Balance (user), User message.
