Pin layout for RS-232C
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
fi
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.
Communication parameters
With the power off, this display responds to PON command
only.
