(3) Error Detection
If the recorder receives the data that has resulted in a signal error such as a parity error, framing error,
etc. due to the noise or hardware troubles, it will ignore that data. Consequently, a data format error
results, determining that the data is not sent in the normal data format. The receiving function does not
execute that command and the transmitting function does not reply. The data format error status can be
confirmed by the ESC S command (described later).
(4) Control codes
ESC: 1B HEX (hexadecimal)
This code is used for an escape sequence such as opening/closing the link.
It cannot be treated as part of the text data.
CR: 0D HEX (hexadecimal)
This data is added to the end of the text data together with the LF data.
This code cannot be treated as part of the text data.
LF: 0A HEX (hexadecimal)
This data is added to the end of the text data together with the CR data.
This code cannot be treated as part of the text data.

Opening/Closing the Link

To communicate with the recorder, you must establish a connection between the host computer and
the recorder. In case of one-to-N communications, it is necessary to inform each recorder which
recorder the text is being sent. If a link open command is sent to multiple recorders through their send
function, all the recorders, which have received the command, will send and cannot receive the normal
data.
