Software Setup
The system defaults to all aux buses being part of the MISC E-MEM
level. When an aux bus is configured for use with an external
DPM, its settings are no longer saved in the MISC level but are
saved in the relevant DPM level when an E-MEM register is
learned. Information (such as aux bus crosspoint selection) is
learned for each DPM on separate E-MEM levels.
In cases where it is not desirable to have an aux bus selection
learned/recalled on the MISC level, it is possible to configure the
aux bus to a DPM level (such as DPM 4) and never enable that level.
An example would be if the aux bus were controlled by a Remote
Aux panel.
DPM Capabilities (Fixed and Pooled)
The characteristics of the DPM are configured in the DPM Setup
Menu. The first choice to be made is selection of DPM TYPE from
NONE, KSCOPE, OTHER POOL
1
, or OTHER FIXED.
The DPM TYPE of NONE indicates that there is no external DPM
device used for the particular DPM level. However, it can also be
used for cases where aux buses are assigned to a DPM level, but
there is no physical device, no return signal, and no control
connection (for example, an aux bus dedicated to feeding a video
monitor).
Both KSCOPE and OTHER POOL are selections for pooled devices.
A pooled device is one which provides acquisition of logical
channels from a pool of physical channels.
Kaleidoscope is a pooled device. As an example, consider a
Kaleidoscope having 5 physical channels named A, B, C, D, and E.
The pooled channels are shared by different users. A user may
build a Kaleidoscope effect using 3 channels. On one day he may
acquire physical channels C, D, and E as logical channels 1, 2, and
3; on another day he may acquire physical channels B, C, and D as
logical channels 1, 2, and 3. The same effect will perform
identically on both configurations since the operator’s view of the
1. OTHER POOL is reserved for future use. It is for DPMs other than Kaleidoscope which are pooled
and use CPL to communicate.
