Cable Connections
For [DPM TYPE] of OTHER FIXED or NONE (DPMs which are not pooled and do
not have Input and Output Routing), the
[CHANNEL ROUTING] selection
should be
OFF.
Kaleidoscope changes its logical-to-physical channel mapping, depending
on the order in which channels are acquired from its pool. Switcher output-
routing maps a physical Aux Bus to a logical Aux Bus so that the logical
Aux Bus number corresponds with the DPM’s logical channel.
The Aux bus button selection made on the switcher control panel is always
a logical Aux Bus; however, unless Kaleidoscope is connected, Logical Aux
Bus 1 always corresponds to Physical Aux Bus 1, etc. (The current mapping
of physical-to-logical DPM channels is displayed in the DPM Map Inputs
menu.)
It should be noted that the switcher supports only one pooled device. Also,
the pooled device must be cabled so that the first physical Aux Bus is
connected to the first physical channel. In the example in Figure 2-26,
Physical Aux Bus 1 is connected to Kaleidoscope Physical Channel A, Bus
2 to Channel B, and so on.
