5. Operation
Operating Concepts
There are fixed and optional category buttons. The fixed category buttons form a keypad within the
arry of function buttons:
The keypad is used under menu mode and under setup mode.
S You cannot perform a name set change using a ‘Nameset Toggle’ button while a category selec-
tion is in progress.
Chop
When a “chop” function is supported by a router, the button is a toggle that enables and disables
“chop.” Chop is a rapid switching of the selected destination device between the current source and
the preset source.
The chop function is used to test system timing and would not be used during normal operation.
The default button text is “Chop” but a chop button can have any legend.
Select a preset source and press ‘Chop’ to start the chop function. Press ‘Chop’ again to stop the
chop function.
Clear
The ‘Clear’ button reverts the panel to the most recent preset. (It does not cause any changes to the
routers, control system, or its signals.)
You may think of this as a “backspace” or “cancel” key. During category/suffix device selection, it
erases the suffixes you entered in reverse order.
(If you are in level mode or in salvo mode, ‘Clear’ brings you back to normal mode.)
Clear Preset
The ‘Clear Preset’ button removes the preset source from a pending take. (It does not cause any
changes to the routers, control system, or its signals.)
The preset source names appear on the middle line of text of applicable LCD buttons. When you
press ‘Clear Preset’, the middle line of text becomes blank.
Default State
The ‘Default State’ button returns the panel to its most recent power-up state. That is called the
default state. (It does not cause any changes to the routers, control system, or its signals.)
Destination Mode
The button places the panel in destination mode. Category selections in destination mode select
destination devices. Category buttons that are not configured with destination categories become
disabled.
