Introduction
The SG-15
Colour
acts a normal remote terminal; Every received ASCII value (between
20 and 255), which isn't part of a command, is normally displayed on the screen.
Furthermore, the Shuttle
C
is controllable and easily configurable by means of ESC
(Escape) commands to customize the following parameters;
• Cursor Control
• Clearing the Display
• Aligning Text
• You can remotely turn OFF and ON the Shuttle
C
from the Back-Office
application. It is strongly recommended to use this feature, during the stores’
closing hours and when the article database is not available. It will save
energy, extend the lifetime of the Shuttle
C
and shows a sustainable system
design. "The SG-15
Colour
The Green Price Checker".
Due to the fact that the SG-15
Colour
uses proportional fonts (every single character
has it's own specific width), you never know precisely how much characters fit
on one line. Therefore, when a character doesn't fit on the current line, it's not
displayed at all (instead of printing it on the next line, which gives undesired
"messy" results)
You can move to another line by sending a Carriage Return (0x0d), or a Linefeed
(0x0a). Both have the same effect: Going to the start position of the next line).
You can move the cursor by sending:
- 'Set cursor' command (ESC 0x27), for predefined cursor positions.
- 'Set Pixel Position' command (ESC 0x2C),
for placing the cursor on any pixel location.
For easy alignment of text on often desired positions (like the center of the
screen, right of the screen, bottom of the screen, etc) you can use the
'Align text' (ESC 0x2e) command.
