SERIAL Terminals connection
Notes:
• Use the RS-232C straight cable to connect the computer to the Display.
• The computer shown is for example purposes only.
• Additional equipment and cables shown are not supplied with this set.
The SERIAL terminal conforms to the RS-232C interface
speci
fi
cation, so that the Display can be controlled by a
computer which is connected to this terminal.
The computer will require software which allows the
sending and receiving of control data which satisfies
the conditions given below. Use a computer application
such as programming language software. Refer to the
documentation for the computer application for details.
The SERIAL terminal is used when the Display is controlled by a computer.
Pin layout for SERIAL Terminal
Basic format for control data
The transmission of control data from the computer
starts with a STX signal, followed by the command, the
parameters, and lastly an ETX signal in that order. If there
are no parameters, then the parameter signal does not
need to be sent.
