An
ANEW daughter board from Sabtech Industries Inc. provides type C
channels for enhanced data speed to 400K words per second (32-bit)
and allows remote operation up to 6,000 feet. The new, daughter
board, used with an IBM-PC-compatible Navy tactical data system
emulator board, accompanies Sabtech NT1632FS AT/NTDS Adaptor board
that emulates the NTDS software and hardware interface common to the
data distribution on most U.S. and allied nation service ships. When
the ANW1632 ANEW daughter board is used with the NT1632FS full
duplex 32 bit I/O interface board, the dual board set fits into any
IBM-PC compatible board slot.
Sabtech designed and developed NTDS/IBM-PC interfaces that
provide low cost hardware and software emulation of NTDS tactical
computers such as the AN/UYK-7, -20, -43 and -44. The company's
interface cards an, oil in IBM PCs and compatible where security,
budget or availability of the tactical computers would otherwise

for I/O drivers, permitting users to write custom and diagnostic
software. With the dual board set, consisting of the NT1632FS
AT/NTDS adaptor board and ANW1632 ANEW daughter board, users can
interface with NTDS type C channels, whereas the AT/NTDS adaptor
card alone only handles type B and A (fast and slow respectively)
operations. The dual board Set replaces the NTDS type B/A negative
voltage I/O line. Which with its balanced line driven and receivers
can interface, with up to eight peripherals at distances of 6,000
feet compared to 200 feet and one peripheral with the AT/NTDS
adaptor board alone.
Mounting the ANW1632 ANEW board to the AT/NTDS board is
accomplished with two female headers. The resulting two-board set
creates a low-profile design that fits in a single IBM PC/AT/XT or
Zenith 248 full-length card slot The card set automatically adapts
to the eight-bit IBM-PC bus and uses 8-bit or 16-bit DMA channels in
the IBM-PC/AT.
