SEND BITMAP
You can set the bitmap image to be displayed on a sink device. Up to four bitmaps can be registered. IDK’s
logo is displayed by factory default.
Bitmaps can be enlarged but cannot be reduced. The larger a resolution, the longer output time. It may take a
maximum of approximately six seconds to output a bitmap. Register a bitmap having smaller resolution than
that of the sink device.

Conditions of bitmap file
The MSD supports DIB (Device Independent Bitmap) with a header generally used for Windows, and those
files meet the requirements in the table below.
[Table 8.22] Conditions of bitmap file
Item
condition
File header
“BITMAPFILEHEADER”
Information header
“BITMAPCOREHEADER”(for OS/2) /
“BITMAPINFOHEADER”(for Windows)
The number of colors
2 colors (monochrome, 1 bit), 16 colors (4 bits), 256 colors (8 bits), 16.77
million colors (TRUE COLOR, 24 bits)
Resolution
The maximum resolution: [Horizontal resolution x Vertical resolution x The
number of bytes per pixel] = 8,388,608 bytes or less. If you register several
bitmaps, the total bytes of all bitmaps should be 8,388,608 bytes or less.
(Aspect ratio does not matter as long as it is within the maximum resolution).
Bytes per pixel: 1 byte per pixel for 2 colors (monochrome, 1 bit), 16 colors (4
bits), and 256 colors (8 bits); 3 bytes per pixel for 16.77 million colors (TRUE
COLOR, 24 bits).
Compression format
No compression (BI_RGB), 8 bit-run-length compression (BI_RLE8), 4
bit-run-length compression (BI_RLE4)

Transferring bitmap file
If you divide memory area, select the register area and then select the bitmap file from the file input field.
Click the “SEND” button to open the dialog box and click the “OK” button to transfer the bitmap file.
When the transfer is completed correctly, the message will appear. Click the “OK” button to register the file.
Do not operate other web menu or turn off the MSD until the registration is completed. If the registration fails,
one of the following error messages will appear.
[Table 8.23] Error message
Error message
Error description
File Name is invalid.
The file name was specified incorrectly.
File Format Error is happened.
The MDS does not support this file.
File Size exceeds the capacity.
The resolution exceeds the maximum resolution.
Memory Allocation Error is happened.
Enough memory to save the bitmap file temporarily could not
be allocated. This error can be solved by turning OFF/ON the
MSD main power switch and sending the bitmap file again.
