These are the signals
transmitted to the DSP
board from the Tape
inputs.
What happens is this:
Two analog signals are
converted into digital and
combined into one digital
signal.
For example, analog
signals 23 and 24 (from the
DB25 pin connector on the
rear panel) are converted
and combined to create a
digital signal DR4 on the
tape card. This is then
given a new name of
DRO_U16 and sent to the
DSP board using connec-
tor J47, pin 16.
TAPE CARDS continued
NOTE: All three tape cards
are identical, and the
difference in signal name
comes from where each
card is fitted in the
backplane slots. If a card is
fitted into slot 1-8, it
connects to the
backplane’s J18 and so for
example, the card’s DT2
becomes DT_20 on the
backplane and DSP board.
If the card is in the 9-17
slot, it uses J19 and so the
card’s DT2 becomes
DT_12.
