3—2P3 PMC Carrier Board
2P3 PMC Carrier Board Overview
User I/O on the 2P3 PMC Carrier Board can be accessed from the VME P2 connector.
As explained in Section 3.2.3.1 on page 3-8, user I/O on the 2P3 PMC Carrier Board
can be reconfigured. For example, 64 bits of user I/O can be made available on PMC
Module slot 1, presuming the user I/O on PMC Module slot 2 is not used. On the
other hand, 32 bits of user I/O can be made available on both PMC Module slot 1
and PMC Module slot 2.
Note:
The available paddle boards cannot be used for VME P2 connection. You
will need to provide your own connectivity, or call Themis Customer Support for
a cost estimate on building a
custom
Paddle Board.
Note:
User I/O signals can be brought from PMC Modules in
slot 1
and
slot 2
to
the VME P2 connector of the 2P3 PMC Carrier Board.
A PMC Module in
slot 3
has
no
I/O-signal access through the VME P2 connector
of the 2P3 PMC Carrier Board.
Caution:
It is important to make sure that a solder-bead configuration does not
result in an
unwanted change
of system operational parameters. READ ALL
SOLDER-BEAN CONFIGURATION DESCRIPTIONS CAREFULLY. (See
Table 3-7
on page 3-15.)
