Hall displays

47.4.1 Communication
The data distribution board sends serial data to the hall
display through the RS232 port. The serial data consists
of ASCII text with ANSI escape codes for special
functions. Refer to table 47.5 for the descriptions of
<CR> and <LF> control characters.
table 47.5: ASCII control characters
Character Description
<CR> Moves the cursor to the first location
on the current text line.
<LF> Moves the cursor one row down in the
current column
The data distribution board only sends ANSI codes and
binary data to status displays.
47.4.2 ANSI support
47.4.2. 1 Introduction
The connected hall display must be able to process all
the ANSI escape codes that are listed below.
Note
Not all of these codes are currently in use, but
they must be implemented in the hall display for
future compatibility.
47.4.2.2 Cursor location
<esc>[<line number>;<column number>H
<esc>[<line number>;<column number>f
figure 47.3: Cursor location

number and column number is specified, the cursor
moves to the upper left corner of the hall display (text

47.4.2.3 Cursor up
<esc>[<numlines>A
figure 47.4: Cursor up
Moves the cursor up in the same column. The number
of text lines that it is moved is defined by numlines. If
the cursor is already in the first text line, the hall display
must ignore this escape function. If numlines is omitted,
the data distribution board moves the cursor one text
line.
47.4.2.4 Cursor down
<esc>[<numlines>B
figure 47.5: Cursor down
Moves the cursor down in the same column. The
number of text lines that it is moved is defined by
numlines. If the cursor is already in the last text line, the
hall display must ignore this escape function. If numlines
is omitted, the data distribution board moves the cursor
one text line.
47.4.2.5 Cursor right
<esc>[<numlines>C
figure 47.6: Cursor right
Moves the cursor to the right in the same text line. The
number of columns that it is moved is defined by
numlines. If the cursor is already in the last column, the
hall display must ignore this escape function. If numlines
is omitted, the data distribution board moves the cursor
one location.
