This completes the procedure to perform a Downstream Key.
DSK Source Bus Setup
Unlike the upper MLE Keyers, there is no Key Bus on the Program/Preset MLE . Instead, each
Downstream Keyer Group has a series for
Source
buttons on the DSK Source Bus . When
programmed, each Source button will have the Key Type and input crosspoint stored in it. By
selecting a Source button, the programmed Key Type and crosspoint will be recalled in that Keyer.
Although this is typically performed during switcher setup, you can assign Key types and crosspoints
during production as required. Often, one of the
Key Bus buttons is left open for just this purpose.
Assigning DSK Source Types
Use the following procedure to program a crosspoint on the DSK Source Bus of a DSK:
1. Press and hold the
Source
button that you want to program a Key Type to.
DSK Source Buttons
2. Press any one of the four Key type buttons ( SELF KEY , AUTO SELECT , CHROMA
KEY , and PST PATT ) in any MLE Keyer.
3. Release both buttons. The key type is now stored in memory for the selected button.
This completes the procedure for assigning a DSK Source Type.
Assigning DSK Source Crosspoints
Use the following procedure to assign a crosspoint to a Source button:
Note You can set the individual DSKs to be taken off-air with a manual
crosspoint change on the
PGM bus. Refer to Chapter 9 “ Additional
Installation Setups ” in the Synergy Series Installation Guide for
more information.
Important Individual DSK Sources can be locked during setup, preventing a user
from assigning new Key types or crosspoints to the locked Sources.
Refer to the section “
Locking/Unlocking a DSK Source Button
Setup ” on page 7–43 for more information on locking a DSK Source.
Note If you have enabled the L.A.S.T. protocol option, a delay will occur
when you select crosspoints directly on any key bus, including
changing DSK sources. Refer to Chapter 7, “
Basic Communications
Setup ” in the Synergy Series Installation Guide for more information
on setting up this option.
