804 Series Video Test Generator – User Guide
1. Load your bitmaps on to the SD card from your PC using a USB SD card reader.
2. Create the UserPats.txt text file listing your bitmaps. Use the information in Table 8-2 below to construct your text file:
Table 8-2: Importing Bitmaps – UserPats.txt file
Bitmap Name (use 8.3 naming convention)
Mast480.bmp
Mast720.bmp
Mast1080.bmp
3. Transfer your UserPats.txt file from your PC to the SD card using standard Windows methods for transferring files to a
USB drive, i.e. by dragging and dropping or copying and pasting.
4. In this example, you would have created a bitmap called for example 980_640.bmp and stored it on the SD card. In this
example the bitmap is 640 x 480 resolution. You would then create a userpats.txt file as follows:
5. 980_640.bmp 980 640x480
Note: Your bitmaps are limited to 8 characters with an extension (.bmp).
6. Insert the SD card into your 804.
7. Power cycle the 804.
8. Navigate to the Video Pattern menu.
You should now see the new bitmap image(s) (980 640x480) on the pattern list (below).
