3. OPERATION
3.1 Front Panel
3.1.1 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.
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.
This LED has no function on the V6334, but will follow the state of the
HD/SD LED.
