TALLY STRUCTURE & BEHAVIOR
Return Tallies:
The first section following the preamble willl define
whether the tally is giving information about
Mechanism Status (D0h), Tape Status (D6h), or
Tape Counter (DAh) tally.
For Mechanism Status tallies, following bits will
represent the current function of a deck, which
mechanism is being described, and the direction the
system is defaulted to. (Side A or Side B)
For Tape Counter tallies, the data blocks will
represent the Mechanism first, then the minutes and
seconds. If the 322 is in CPS mode, the minutes
display will transmit "CP" and the seconds will show
the number of breaks the CPS mechanism is going
to pass. (This is exactly mimicking the timer display
on the 322.)
It should be noted that the 322 will not transmit
positive or negative time information from the deck,
though the display can indicate negative time.
As with the FFWD and REW transport commands, FFWD and REW
tallies do not reverse for side B. They are always shuttling tape
in the same direction. So, on side B, REW will shuttle ahead, and
FFWD will shuttle back. This is consistant with having a dedicate
PLAY B button, keeping the relational arrows for commands.
