Communication parameters
The SERIAL terminal conforms to the RS-232C interface
speci 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 satis es
the conditions given below. Use a computer application
such as programming language 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 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.
