4 LOCK (CHOP) button/lamp
This button has two functions: lock function and chop
function.
Lock function
Press and light this button in red, and the buttons on
the front panel other than this button are disabled.
This prevents switching by touching the select buttons
accidentally.
If you press a select button while the LOCK lamp is lit
in red, the STATUS button blinks in red.
Chop function
When you hold the button pressed for about three
seconds while the button is not lit, the button lights in
green, and the chop mode is obtained. In chop mode, a
source before the chop mode and a source selected in
chop mode are switched alternately at a specific
interval.
5 Source/destination select buttons
These buttons can be used as source select buttons or
destination select buttons. The control terminal or the
setup function of this unit defines the function of these
buttons.
The source select buttons normally light in dim green,
and the destination select buttons normally light in dim
amber. When you press one of the buttons, the pressed
button lights in bright green or amber to show that it is
selected.
Notes
• When the source select button is lit in bright amber,
the source has been selected on another level in the
break-away function.
• In 4 DESTINATION mode, dual function setting is
enabled on buttons 1 to 4. Adding to source select
function, destinations for blocks 1 to 4 are set to
destination select buttons 1 to 4.
For details on defining the button functions, refer to the
Installation Manual supplied with the routing switcher.
Source selection function (lit in green)
When you press a button, the signal fed to the switcher
(source) corresponding to the pressed button is
selected and is supplied to the output connector
(destination). If the phantom function has been set, the
sources set for the button are selected.
If prompt lamp-light mode has been set, the pressed
button lights in bright green to show the selected
source. If status display mode has been set, the system
checks that the selected crosspoint has been switched,
and the button lights in bright green.
For details, see page 15.
