COMMANDS
Use SHARP BASIC commands to send data to the plotter. |f the BASIC commands are expressed
as described in the form of [ H] in the following sections.
1. Model Selection Instruction and
2. Commands in the TEXT mode,
use the CHR$ { ) command.
Example:
An instruction for creating commands in the TEXT mode takes the form below.
ESC [1BH] + “a = CHR$(27) + “a"
1. Mode Selection Instruction
The plotter can be used in either of two modes: TEXT or GRAPH. |n the TEXT mode, it func-
tions as a pen printer. In the GRAPH mode, if functions as a plotter. It is in the TEXT mode
when the power is turned on (initial state), when the reset button is pressed, or when the EXPRM
signal (parallel interface) is received.
ESC [1BH] + *a”
Shiftto TEXTmode . ..........
A instruction
Shift to GRAPHmode ............ ESC [1BH] + “b"
2. Text Mode Commands
(1) BS[O8H] ....... Back space
The pen back-spaces by one character. If the pen is at the left margin, this instruction is
ignored.
(2) LF [0AH] ....... Line feed
The paper is fed one line. The pen doesn’t move.
(3) LU[OBH] ....... Line up
The paper is rewound by one line. The pen doesn’t move.
(4) CR[ODH] ....... Carriage return
The pen is moved to the left margin. If the CR-CR/LF of the DIP switch is on the CR/LF,
the pen is moved to the left margin of the next line.
(5) ESC [1BH] +“a"....... Mode change (to TEXT mode)
The plotter is set to the TEXT mode.
(6) ESC [1BH] +“b"”....... Mode change (to GRAPH mode)
The plotter is set to the GRAPH mode.
(7) ESC [1BH] + ““?” + “a" to ““0"" (Character scale set)
Set the size of the characters in the Character Table in APPENDIX 1 (20H to 7FH and AQH
to DFH). The size is set as a multiple of the smallest character (ESC + “?”" + “a”’) from x 1
(a) to x 15 (0). The initial value is x 2 (b).
