RS-232C Straight cable
The SERIAL terminal is used when the Display is controlled by a computer.
The  SERIAL  terminal  conforms  to  the  RS-232C  interface 
specification, 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.
Notes
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.
If an incorrect command is sent by mistake, this unit will 
send an ER401 command back to the computer.
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.
