RS-232 (OPTION):
The displayed time of year is outputted
in EIA Standard RS-232C configuration via
a "Motorola ACIA". Output format is
D D D H H M M S S and an indicator of the
time quality, CR/LF. Baud Rate and "ACIA"
options are dip switch selectable.
See Section 3-67.
IEEE-488 (OPTION):
IEEE Buss interface is also available. The
time is outputted in ASCII format, with the
most significant digit first (100's of days).
Among operating modes is time on demand to
the millisecond level, or marked time to
the milliseconds level. See Section 3-99.
