• DTC mode: byte 30
X’20’ is set when the power is turned on.
This byte is valid when the IPC-2D or IPC-3D is installed, and byte 3E is X’40’.
*1 When this bit is “0”, the output video data is black if the gradation of the video data is equal
to or larger than threshold. When this bit is “1”, the output video data is white if the
gradation of the video data is equal to or larger than threshold.
