Direct Indications
The four LEDs at the top of the panel provide these direct indications of the unit:
3.1.2
Display and Switches
The main display is an eight character LED matrix display. It has been set so that when fitted into a 3U
rack (V1606) it can be read from the left, and when fitted to a 1U rack (V1601) it is horizontal and the
‘proper’ way up. (At time of writing it is not possible to fit the HD products into the V1602 1U rack.)
The three action buttons are labelled
Select
,
▲
and
▼
. The
Select
button is used to move down and up
the menus. A short press will move down one level, while pressing and holding for about half a second will
move up one level. If you continue to hold it will progressively move up a level every half second until it
reaches the top level (
SLEEP
), or you let go, in which case it will stay where it is. When at any level the
▲
and
▼
buttons will move through the list of options, or if in an actual variable (such as Video Gain) they will
change the values.
If the unit is in Local control then the display and switches are used to set up and show the operation the
module. If in remote mode then they are still active for showing the status but cannot be used to actually
change anything.
REM
Short blinks to indicate access by the DART controller, if fitted.
It does
not
directly indicate that the unit is in remote control
mode. If the rack frame does not have a Rack Controller fitted
then this LED will not blink.
+V
Indicates that the main +3.3V is present on the board. This is
derived from the +15V distributed through the rack. The
modules do have many power rails, but only the main +3.3V is
indicated here. It will, of course, be off if the fuse, FS1, were
to have been blown.
HD/SD
Indicates that a valid SDI signal (either HD or SD) is being
received.
Ref.
Indicates that the selected audio reference signal is being
received – either the video input, an audio input or nothing; in
which case the LED is always on.
