12.2.1 Control of a Dual Frame System
To link two Sirius 850 frame together it is recommended that they are both fitted with the same
router controller type, either the Nucleus 2450, the Nucleus2 2464 or the Nucleus2 2463. The
Nucleus modules control the main crosspoint modules of the local router and the expansion
crosspoint modules of the remote router. Connecting the control busses of both frames
together (Figure 138) enables the controllers to route the video input signals in the remote
frame to the outputs of the local frame. The controller in the second frame works in the same
way enabling control of up to 1152 x 1152 video across the two frames.
In a dual frame system, the controllers are connected using standard Cat 5e Ethernet cables
(see Table 51 for connections) as follows:
RJ45 connectors “Local A” and “Local B” take the local control signals (both outgoing clock
and data and incoming data) from the local controller out to a remote frame. The connectors
“Remote A” and “Remote B” receive commands from a remote controller and send the data
back to the remote controller.
Enabling video redundancy in frame one will enable redundancy for the main crosspoint
modules mounted in frame one and the expansion crosspoint modules mounted in frame two.
The reverse is true for frame two.

Note:
In a dual frame system if redundancy is enabled in one frame it must also be enabled in the
other frame. see section 10.2 for details on enabling/disabling video redundancy.
