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.

Notes:
• If multiple commands are transmitted, be sure to wait for
the response for the rst 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.
• Consult an Authorized Service Center for detail instructions
on command usage.
