TERMINAL MODE
When you switch the unit on, the cursor flashes in the first line, indicating that the display is ready for
operation. All the incoming characters are displayed in ASCII format on the terminal (exception:
CR,LF,FF,ESC,’#’). Line breaks are automatic or can be executed by means of the ‘LF’ character.
If the last line is full, the contents of the terminal scroll upward. The ‘FF’ character (page feed) deletes
the contents of the terminal display and positions cursor in the upper-left corner.
The terminal has its own layer for display and is thus completely independent of the graphical output;
moreover, the size of the terminal window can be freely defined. If the graphics screen is deleted with
‘ESC DL’, for example, that does not affect the contents of the terminal window (the terminal level is
deleted with ‘FF’).
The character ‘#’ is used as an escape character (see below) and thus cannot be displayed directly
on the terminal. If the character ‘#’ is to be output on the terminal, it must be transmitted twice: ‘##’.
COMMAND TRANSFER/PARAMETERS
The operating unit unit can be programmed by means of various integrated commands. Each
command begins with ESCAPE followed by one or two command letters and then parameters.
There are two ways to transmit commands:
1. ASCII mode
- The ESC character corresponds to the character ‘#’ (hex: $23, dec: 35).
- The command letters come directly after the ‘#’ character.
- The parameters are transmitted as plain text (several ASCII characters) followed by a separating
- Strings (text) are written directly without quotation marks and concluded with CR (hex: $0D) or LF
2. Binary mode
- The escape character corresponds to the character ESC (hex: $1B, dec: 27).
- The command letters are transmitted directly.
- The coordinates xx and yy are transmitted as 16-bit binary values (fiirst the LOW byte and then
- All the other parameters are transmitted as 8-bit binary values (1 byte).
- Strings (text) are concluded with CR (hex: $0D) or LF (hex: $0A) or NUL (hex: $00).
No separating characters, such as spaces or commas, may be used in binary mode. The commands
require no final byte, such as a carriage return (apart from the string $00).
