A Word About Adding Additional Matrix Bays to Existing Field
Installations
If expanding your existing system by sideframing, decouple the monitors connected
to the original bay (leaving the cables connected to the output card, if possible) and
connect these open cables to the first 16 video inputs of the new bay, having it now
become the OUTPUT bay.
This way, the already programmed video inputs for the
original bay can be left alone and all you have to program are the new video inputs.
The same type of scenario applies to any additional matrix bays that are to be
sideframed. As a general rule, to minimize programming time as new bays are
added to a system configuration, they should be installed and configured as the
OUTPUT bay. For example, to continue adding bays to the two bay-configuration
just discussed, decouple the monitor outputs of the existing OUTPUT bay (second
bay) and input them to the second 16 video inputs of the new bay which now becomes
the OUTPUT bay (third bay). Also detach the monitor out cables of the original bay
from the first 16 inputs of the second bay and route them to the first 16 inputs of the
new bay. Doing this, minimizes the amount of reprogramming within your configu-
ration.
If more video inputs are required than are available with two matrix bays, then, in a
similar manner, additional bays can be sideframed up to a maximum of eight (physi-
cally there are nine bays; eight are sideframed to the last bay which is referred to as
the OUTPUT bay). Figure 33 illustrates three sideframed matrix bays and one out-
put bay. When you order an entire system from the factory, all the matrix bays with
their associated boards and connecting cables are tested and properly configured
for your system.
