CPU board
The CPU board controls amongst other the remote power on/off mechanism between P
ROCESSOR
and the O
MNI
B
US
devices and the transmission of a genlock signal. It is part of each O
MNI
B
US
.
Connectors
On the CPU board there are two RJ-45 connectors for connecting the remote power on/off cables.
Do not remove the sheet metal plate. The connector behind is reserved for diagnostic
purposes.

A devices of an OmniBus configuration should be connected in a daisy chain for remote power
on/off mechanism. Therefore the
remote power on/off
connector [16] on the back of the P
ROCESSOR
must be
connected with the
remote power on/off in
connector of the CPU board of the first O
MNI
B
US
. The
remote
power on/off out
connector of this O
MNI
B
US
must be connected to the
remote power on/off in
connector of
the next O
MNI
B
US
and so on. The
remote power on/off out
connector of the last O
MNI
B
US
remains unconnected.

Do not mix up the connetors for remote power on/off with the mechanically identical
connectors of the network adapters!
Mixing the connectores will cause damage to the system!
