8.2.2 Opening/Closing the Link
To communicate with the recorder, a connection between the host computer and the recorder
must be established. In the case of one-to-N communications, it is necessary to inform each
recorder to which recorder the text is being sent. If a link open command is sent to multiple
recorders through their sending function, all recorders which have received the command will
send data. As a result, normal data cannot be received.
1) Open Command
(ESC)O
01
(CR)(LF)
Address (01 to 32)
Space (20 Hex.)
To communicate with the recorder, the host computer must issue this command and must
memorize that it has issued this command.
2) Close Command
(ESC)C
01
(CR)(LF)
Address (01 to 32)
Space (20 Hex.)
When sending data to the recorder to which the open command has not been issued, the host
computer must issue this command to the reocrder to which the open command has been issued.
