SERIAL terminal
The SERIAL terminal conforms to the RS-232C interface specification, so that the Wide Plasma Display can be
controlled by a computer which is connected to this terminal.
You can control the Wide Plasma Display with a computer by using the TY-SCP02RS1E (optional accessory).
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 a programming language to create the software. Refer to the
documentation for the computer application for details.

Basic format for control data
The transmission of control data from the computer starts
with an 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.

Note:
(1 ) If multiple commands are transmitted, be sure to wait
for the response for the first command to come from
this unit before sending the next command.
(2) If an incorrect command is sent by mistake, this unitwill
send an “ER401” command back to the computer.
