Communication
and Indication
Communication (UART, I
2
C and ESPI) and
indication signals (reset, disable, etc) running
between MB and DB, using flat cables connected
to J2 (PoE domain) and J3 (Host Domain)
connectors.
5
MB: J4
Isolated External
HOST
Control and indication signals running between an
external hosting system and MB (Host Domain on
the daughterboard), of limited use as most of the
communication is via USB, UART, and RS232.
6
MB: U7
Isolated USB
USB communication coming from hosting system
(U7), converted to UART or I
2
C communication
and directed to DB (Host Domain on
daughterboard)
7
MB: J33
Isolated RS232
RS232 signal levels coming from the hosting
system (J33) and converted to UART signal levels,
then directed to DB (Host Domain on
daughterboard).
8
MB: J26
Isolated UART
UART interface from hosting system and MB, then
directed to DB (Host Domain on daughterboard).
