Command Description
Text
Write Text DM ―$A5,<dh>,<dl>,<ncb>,‗DM‘, <start line>,<text color>,<background color>,
<background>,<size and shadow>,<timeout>,<message bytes>‖ (variable bytes)
Clears current text, displays text message over video (default) or blank background.
The built-in character generator can accept up to 40 characters of text (including
carriage returns), 28 characters per line. Use a hex $0D or decimal 13 in the text as a
carriage return, which will advance CG to the next line, first space on the right.
Start Line - 1-11
Text Color - 1-7= White
Text Background Color – 0-7=Transparent (no background)
Full screen background – 0=normal insert over video, 1=blank screen (blue)
Size and Shadow – 0-3=small text with drop shadow
Time-Out – 0=15-second display, 1=persistent
Persistent text stays on screen until the next DM, or new Menu or channel.
Ex1: ―$A5,<dh>,<dl>,10,‗DM‘, 2,7,0,0,1,0,‘TEST‘ ‖ displays the word TEST on the
second line, white text, inserted over video, small size with drop shadow, and timing
out after 15 seconds.
Ex2: ―$A5,<dh>,<dl>,2,‗DM‘ ‖ clears on-screen display, also clears persistent text
The VDC uses white text and clear backgrounds when it receives a Text or
Background Color parameter between 1 and 7, and accepts values 0-3 for text size
and shadow. This allows compatibility with Smart TVs mixed in the same system that
can display other colors and fonts.
Fast Write DN ―$A5,<dh>,<dl>,<ncb>,‘DN‘, <text> ‖ (variable bytes)
Clears display, writes specified text starting at column 1, row 1. $0D and hex $EA,
$EB, $DC, and $DB can be included, operate same as matching commands below.

Writes specified text starting at present cursor position. Accepts same Hex as DN.
Row, Column DG ―$A5,<dh>,<dl>,4,‘DG‘, <row>, <column>‖ (8 bytes)
