The following example uses the Digital488HS/32 as an IEEE 488 to Parallel
(Centronics) converter. It uses only the output port in 8-bit mode. The IEEE 488 bus
address of the Digital488HS/32 is assumed to be 08. This simple example could be
expanded to include error reporting of the parallel BUSY, PAPER and /ERROR
signals. All it attempts to do, however, is print a text file, "TEST.DAT," to the
parallel printer.
