Usb Interface - PSI Matrix PP 404 Benutzerhandbuch

If the serial interface starts to receive data while the parallel interface is active, it
is possible to receive 256 bytes of serial data. Any additional serial data will be
lost.
When the interface buffer is completely empty of serial data, and no new data
has been received by the serial interface for more than 10 seconds, both
interfaces are available for data transfer again.
When the interface buffer is completely empty of parallel data and no data has
been received by the parallel interface for more than 60 seconds, the 256 bytes
of serial data will be processed. Afterwards, both interfaces are available for
data transfer again.
