The number of data values depends on the
oscilloscopes memory
setting. For details
manual.
Data from channel I is always sent before
that of channel II; there
between the data
nets.
A hardware synchronization
i.e. the data receiving device (e.g. computer
or printer) must capture and store the data
fast enough. Otherwise
should be used. The XOND<OFF protocol will
be supported. It is recommended

It is not permitted to switch on the interface
