CPU board
The CPU board controls amongst other the remote power on/off mechanism between the O
MNI
B
US
devices and
its host 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.

Connecting order remote power on/off
Each O
MNI
B
US
should be connected to its host for the remote power on/off mechanism. Therefore the
remote
power on/off
connector [16] on the back of the host (P
ROCESSOR
in a monolithic system, rendering P
ROCESSOR
in a
distributed system) must be connected with the
remote power on/off in
connector of the CPU board of the
O
MNI
B
US
. Multiple O
MNI
B
US
devices are connected in a daisy chain to their host by connecting the
remote power
on/off out
connector of the first O
MNI
B
US
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.
