Switcher Description Table
2. Enter a name for both the Switcher and Level.
Row numbers on Jupiter tables are used as the “logical” numbers for
levels (Figure111). Changing the row number
of a level (by inserting/
deleting a new level in the middle of the
table, for example) will disrupt
control of the system, requiring controller boards to be memory-cleared
and reset.
One way to avoid this inte
rruption is to add new levels at the end of
tables. Adding new levels in the middle of the table will also clear all
entries in the Switcher Input and Output tables.
Normally one switcher is named, using up to eight characters.
The level name (also called “logical level
name”) can also be up to eight
characters. All of the following information entered on this menu will
apply to this level. Conventional names are “VIDEO,” “LEFT,” “RED,”
“GREEN” and so forth.
For a Venus “ES 401” digital audio switcher with two-level stereo mode
har
dware settings, there must be an entry for the Left level and another for
the Right level; this will allow special stereo mode switching such as Mix
and Reverse. If the ES 401 switcher’s hardware is set for one-level stereo
mode, or for one-level mono mode, or if a Venus “ES 400” digital audio
switcher is being configured, only one entry is needed. For information
about setting the Venus hardware, refer to the Venus Installation manual.
Note In this manual, “ES 401 switcher” refers to the AES11 synchronous/asyn-
chronous version of the digital audio switcher matrix board and its associated
components; “ES 400 switcher” refers to the original asynchronous (non-
reclocking) version of the digital audio switcher matrix board and associated
components.
If there is more than one Grass Valley Crosspoint Bus router‡ type in the
system (such as a Venus and a Trinix), there are two possible approaches to
configuration. The additional switcher can be entered as a named level (or
levels) within the main router. However, this will require a unique hard-
ware setting on each level to avoid conflicts (see
your account representa-
tive for A Triton-to-Jupiter Serial Contr
ol Kit, available from Grass Valley.
This kit includes a B&B Electronics 422COR RS-232/RS-422 Converter, a
B&B Universal Power Supply, a 25 ft. (7.6 m) VM/CM to Converter Cable,
and a 5 ft. (7.6 m) Converter to Triton Cable. The part number of this kit is
44-050456-001.). Another solution would be to drive the Venus with one
CM-4400 and the Trinix with another; this would allow level settings to
remain independent.
3. Select the VI (Vertical Interval switching) check box for this level.
Normally checked for the video level and unchecked for all others.
If the CM-4000 is supplied with house
reference sync, checking VI will
cause switches on this level to start in the house vertical interval. In
other words, the level selected on this menu will start switching first;
other levels will follow as soon as possible. Priority is normally given to
