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.

• If an incorrect command is sent by mistake, this unit will
send an "ER401" command back to the computer.
• S1A and S1B of Command IMS are available only when
