Section 2— Startup and Configuration
DPM Configurations
Digital Picture Manipulators (DPMs) are external video devices 
connected to the switcher. In this discussion, reference is also 
made to DPM levels, which are E-MEM levels into which DPM-
associated information is learned. The combined system 
capabilities of the switcher and DPMs depend on:
The video connection
The capabilities of the DPM
The control connection
It is not necessary to have a control connection from the switcher 
to a DPM; however, the highest level of system integration is 
achieved where there is a control connection.
The Video Connection (Aux Buses and Return Inputs)
A normal video signal path consists of an aux bus output from the 
switcher feeding a DPM input and the DPM output returned to a 
switcher input which is mapped to a switcher source select 
button.
The video path through a DPM introduces a video delay into the 
system. For example, Kaleidoscope introduces a 2-field video 
delay.
NOTE:  
If the video delay is not set correctly, there will be a glitch in the 
video upon entering Effects Send mode.
There are four steps in configuring the video path:
Aux buses are assigned to DPMs using the DPM Map Aux 
Buses Menu
Return input connections are configured using the DPM Map 
Inputs Menu
The mapping of a return connection to a crosspoint is done 
using the Configuration/Map Inputs Menu
The video delay is set using the DPM Setup Menu
