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
specifi 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 satisfi es 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.
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.

send an “ER401” command back to the computer.
