•

When using the READY/BUSY control, make sure that the product is in power on mode before you send the data from the host.

•

With communication protocols such as XON/XOFF, STATUS3, STATUS4 or STATUS5, a receive buffer full error will occur when the received data is more than the receive buffer size (2.95 MB). When sending data, monitor the status of the product and keep the size of the data that is sent to less than 2.95 MB.

•

A parity error is detected when an error occurs after receiving the start code <A> command.
