* In general, windows PCs that have serial interfaces receive printer's hardware flow control signal (DTR) through the CTS
pin. But cables sold commercially connect the PC's CTS pin to the printer's RTS pin. Therefore, when using a cable sold
commercially, we recommend the transmission method be changed to Xon/Xoff protocol mode.
Note: Use inch screws for the connector fixing screws.
