Status Level
The default level to be used when displaying the status of a destination receiving signals from
multiple sources, on a panel in all levels mode (ALL LEVS).
One function of the LCD display on a panel is to show which source is currently switched to a
selected destination. This is known as destination status. Although more than one source can be
switched to a single destination (limited to one source per level), the status display can only show
one source at a time. When the panel is in all levels mode (ALL LEVS), Status Level is used to
designate a default level to be used when displaying status. Only the source on this default level
will be displayed. On panels which do not have LCD displays, this is indicated by a continuous,
bright, pushbutton light.
If one or more other sources are also switched to the destination (on other levels), an octothorp
(the “#” symbol) will be appended to the source name. The other source names can be viewed by
toggling each level key in turn to show, level-by-level, which source has been switched to the
destination. On panels which do not have LCD displays, this is indicated by an alternating
bright/dim push button light.
Status Method
One of two possible ways to display status when a panel is in all levels (ALL LEVS) mode and the
destination is not defined on the Status Level.
When a panel is in all levels mode (ALL LEVS), the status shown will be the source on the Status
Level assigned to that panel. If the destination is not defined on the Status Level, Status Method is
used to control the resulting display:
If DEF (Default Method) is selected, NO XXXXX will be displayed where XXXXX is the Status
Level assigned to the panel.
If GRP (Group Method) is selected, the controller will examine every level sequentially, starting
with the level designated as Level Order 1. The source switched on the first level found where the
destination is defined, will be displayed as the destination status.
Stop Bit
In asynchronous communications, a bit that indicates that a byte of data has just been transmitted.
Every byte of data is preceded by a start bit and followed by a stop bit.
Strobe
The third dimension of matrix space.
Every routing switcher in a switching system is assigned a strobe. This is usually accomplished by
setting a DIP switch on the back of the routing switcher. Strobes do not have to be unique and, in
larger systems, each strobe might be associated with several routing switchers.
In many switching systems, strobes are used to group levels of the same type together. For
example, video may be on Strobe 1, audio on Strobe 2, etc.
Sync Reference
A vertical sync signal used to ensure that switching occurs in the vertical interval of a video signal.
Sync Reference names are one to eight characters in length and are constructed using uppercase
letters, numbers, and spaces. The first character must be a letter.
