Switcher Configuration
Switcher Configuration
In order for this interface to function as expected, the switcher must be conÞgured
properly. DPM conÞguration details are covered in the normal switcher
documentation. The following settings should be made prior to integration
testing:
DPM Type
The switcher is capable of controlling several different types of devices. A
selection is made in the CONFIG/EXT IF/DPM SETUP menu. The desired setting
is currently labeled DVEOUS but may be changed to be more generic in a future
switcher version.
The OTHER and NONE selections deactivate the interface port. OTHER is used
for simple device control via GPIs or Peripherial Bus. NONE is used when no
device is controlled, but aux bus assignment and effects send are needed.
KSCOPE, KRYSTAL and INTERNAL use an extended version of this protocol,
primarily to support channel sharing. Use caution: the interface may appear to
partially function with these settings.
NOTE: This protocol is only available for DEVICE 1.
Aux Bus Assignment
A number of aux busses must be assigned to the DPM in order for the switcher to
provide source selection. This assignment is performed in the CONFIG/EXT IF/
DPM SETUP/MAP AUX BUSSES menu.
Input Mapping
The switcher relies on special input mapping for DPM signals returned to the
switcher input. This mapping insures proper tally and effect send operation.
Physical inputs are speciÞed for every video and key signal connected from the
DPM to the switcher in the CONFIG/EXT IF/DPM SETUP/MAP INPUTS menu.
Then, one or more of the switcher sources is deÞned as a LOGICAL input and the
appropriate device and channel is speciÞed. This is accomplished via the
CONFIG/MAP INPUTS menu.
Channel 1 is handled differently than the others. The switcher assumes that
channel 1Õs video actually contains the combined output of all channels in the
system. The DPMÕs combiner output should feed an input conÞgured for channel
1. This assumption affects only on-air tally.
