Rane SR 3 - Manual (Page 39)

Manual-39
Get LCD Image Example
This example first selects page 0 to display the target image to upload. The SR 3 limits
its <command/data> size to 250 characters, so image data must be requested a line at
a time. The Move Cursor and Hex Data Read commands are concatenated. The image
data is represented in ASCII hex so there is a two character representation for each
byte of data. The encoder is locked out before the data requests to prevent someone
changing the display during an upload. See the ILK command in the SR 3 Com-
mand Set section for details. The encoder is then unlocked after the upload to restore
normal encoder operation.
