FUNCTIONAL OVERVIEW
GENERAL (REFERENCE BLOCK DIAGRAM FIGURE 1)
The BU-65528/27 provides a user-friendly interface between
multiple serial MIL-STD-1553 Buses and the VME/VXI bus. The
interface to each 1553 bus is implemented through the use of a
BU-61586 Advanced Communication Engine (ACE) component
(BU-61585 ACE used on BU-65527). The board has the option
for one, two, three, or four ACE components, providing the capa-
bility of interfacing with up to four independent 1553 buses.

Notes:
(1) Assumes all installed 1553 channels (1, 2, 3, or 4) on card are
transmitting at the specified duty cycle on only one of the dual-redun-
dant MIL-STD-1553A/B Notice 2 data buses.
(2) Typical value for minimum intermessage gap time. Under software
control, may be lengthened to (65,535
s minus message time), in
increments of 1
s.
(3) Software programmable (4 options). Includes RT-to-RT Timeout
(Mid-Parity of Transmit Command to Mid-Sync of Transmitting RT
Status).
