DESCRIPTION
The BUS-65112 is a complete dual
redundant MIL-STD-1553 Remote
Terminal Unit (RTU) packaged in a
small 1.9” x 2.1” hybrid. Based upon
DDC custom ICs, it includes two
transceivers, two encoder/decoders,
two bit processors, RTU protocol,
data buffers, and timing control
logic. It supports all 13 mode codes
for dual redundant operation, any
combination of which can be illegal-
ized.
Parallel data transfers are accom-
plished with a DMA-type hand-
shaking, compatible with most CPU
types. Data transfers to/from memo-
ry are simplified by the latched com-
mand word and word count out-
puts. Error detection and recovery
are enhanced by BUS-65112 spe-
cial features. A 14-bit built-in-test
word register stores RTU informa-
tion, and sends it to the Bus
Controller in response to the Mode
Command Transmit Bit Word. The
BUS-65112 performs continuous
on-line wraparound self-test, and
provides four error flags to the host
CPU. Inputs are provided for host
CPU control of six bits of the RTU
Status Word.
Its small hermetic package, -55°C to
+125°C operating temperature
range, and complete RTU operation
make the BUS-65112 ideal for most
MIL-STD-1553 applications.
