FEATURES
DESCRIPTION
• Type II PCMCIA 2.10 Compatible
PC Card
The BU-65552, BU-65551 and
BU-65550 provide full, intelligent
interfacing between a dual redundant
MIL-STD-1553 Data Bus and a PCM-
CIA socket. Software controls these
cards operation as either a 1553 Bus
Controller (BC), Remote Terminal
(RT), or Bus Monitor (MT). The BU-
65552, BU-65551 and BU-65550 are
packaged in a Type II PCMCIA PC
Card. The BU-65552 is designed
around the Mini-ACE Plus, which has
backward compatability to the BU-
61586 and provides 64k x 16 on-
board shared RAM. Using the sup-
plied drivers and libraries, this card
will require only 32k bytes of PC
memory. The The BU-65552, BU-
65551 and BU-65550 feature DDC's
BU-61586 Advanced Communication
Engine (ACE). As such, it includes
and polling applications. The memory
management scheme for RT mode
provides an option for separation of
broadcast data plus a circular buffer
option for individual RT subaddresses
to offload the host CPU.The PCMCIA
interface includes 256 bytes of
attribute memory as well as the four
standard PCMCIA card configuration
registers. Additional features include
a wrap-around Built-In-Test, and soft-
ware programmable RT address
selection. Free C Runtime Library and
comprehensive Menu Applications for
DOS, Windows 95/98 and Windows
NT. These cards support all dual
redundant mode codes and message
formats. Additionally, these cards
allow the use of commercial off-the-
shelf or ruggedized laptop and note-
book computers in applications
requiring a MIL-STD-1553 interface.
Full compliance with both MIL-STD-
1553 and PCMCIA 2.10 make the
BU-65552, BU-65551 and BU-65550
an excellent choice for real-time sim-
ulation, test, and system integration
applications.
