The DXY-1000 series indicates errors if it cannot continue to operate properly, if the communica
tion protocol for a Serial Interface has not been properly set, etc. In such case, the DXY-1000
series lights up or blinks the [POWER/ERROR] LED quicklly to show something wrong. Depen
ding on errors, the DXY-1000 series keeps executing incoming commands, but it cannot ex
ecute the commands at the time of errors and so does not assure of further drawings.
In such a case, you are required to find what has caused an error and solve them.
4.1 Kinds of Errors
Errors are classified into the following 3 kinds.
(1)Command error:
This error occurs when an incorrect RD-GL I command or and out-of-range parameter
has been set.
If you have used a Serial Interface, you can remove errors and know the content of errors
by executing the OE command.
(2)Device control com m and error:
This error occurs when the connection with the computer is a serial connection or when
the device contorl command is improper.
You can remove errors and know the content of errors by executing the [ESC] command.
For more information, see " ESC.E" Command of " Device Control Command" in
CHAPTER 5.
(3)Communication protocol error:
This error occurs when the setting of the communication protocol for a serial connection
is incorrect. If there is a mismatch in the communication protocol (such as the baud rate)
between the computer (software) and the plotter connected to it, a communication pro
tocol error will occur.
Set a proper communication protocol reading Appendix A " DIP Switch Setting Table"
and the operation manual for the com puter (software).
4.2 Judgment of Error
When the connection with the com puter is a serial interface connection, the type of error can be
determined by the computer.
The following BASIC program will perform and error check and display the error number on the
screen. The errors that correspond to these error numbers are listed in the table below.
10 ' *** Error Check Program ***
20 OPEN "COM1:9600,N,8,1" AS #1
30 PRINT #1,"OE;"
40 INPUT #1,CE
50 PRINT " COMMAND ERROR - - " ; CE
