Rane SR 3 - Manual (Page 11)

Manual-11
Fonts
Since the SR 3 supports displaying strings on the LCD display, two types of
fonts are stored in read-only memory. The two types of fonts are text and sym-
bol. The text font allows the host controller to send ASCII character strings to
the display in three different sizes. The symbol font allows the host controller
to send ASCII characters to the SR 3 that are displayed as simple icons in two
different sizes. The symbol font is useful when the end users of the SR 3 are
better served by graphics rather then text such as bilingual applications. When
needed, one can load bitmaps with foreign language characters using MS
Paint and save them in the LCD pages.
A few notes about the built-in fonts. Small font characters are 1 line tall,
medium font characters are 2 lines tall, and large font characters are 3 lines
tall. This is true for the medium and large symbol font icons as well. The LCD
display consists of 8 lines, therefore when using small characters, 8 total lines
are displayable; when using medium characters or icons, 4 lines fit on the
LCD display; and when using large characters or icons, 2 lines fit on the LCD
display.
The protocol and communications details for the text and symbol fonts
are found in the section on Communications. The ASCII character to symbol
icon map is detailed on the next page. A hint: load a graphic image into the
display, then use the STR, SL, SR, or SC commands to overlay the fonts on
top of the graphic image.
