Horizontal scroll
1B 5C 3F 4C 48 Pm 3B Pl 3B Pt 3B Pn 3B Pd...Pd
Purpose:
This command initiates horizontal scrolling. The control bytes embedded in
the command sequence (represented by Pm, Pl, Pt, and Pn in the
preceding command format), change the scrolling characteristics. Pd...Pd
represents the data bytes.
Pm 6 (X'36'): 5x7 dots, 4 rows
7 (X'37'): 5x7 dots, 5 rows
8 (X'38'): 16x16 dots, 2 rows
Pl 1 ∼ 4 (X'31' ∼ X'34'): Pm=6
1 ∼ 5 (X'31' ∼ X'35'): Pm=7
1, 2 (X'31', X'32'): Pm=8
Pt 1 (X'31'): 1 line/10 ms
1 (X'32'): 1 line/20 ms
Pn The number of data bytes (1 for half-size letter, 2 for full-size letter,
maximum is 128 (X'80').
Pd...Pd The data characters.
The following list explains how the horizontal scroll command operates:
v When a character is displayed on the line selected for scroll mode, all
displaying characters and the display mode set command are erased.
v A character scrolls by closed loop until the cancel command is selected.
In this case, the same message is scrolled repeatedly with no space.
v A screen scrolls from right to left, dot by dot.
v The scrolled display range is defined by the screen mode setting.
v The command is canceled when Pn = X'00'. After it is canceled,
displayed characters are cleared, and the write-in position moves to the
most significant digit of the row.
v The command can be started only on a single line.
v A character’s display mode set command (reverse, blinking, and so on)
can be added with the display data frame. If the command is written two
or more times in one scroll data frame, only the first command is valid;
others are ignored.
v When message data is changed, you must reissue this command. While
scrolling, the user definable font set command is not available.
