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 into a '1-Box' (V6011) it is horizontal and the
‘proper’ way up. (At time of writing it is not possible to fit the V64xx 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.
Beside the
▲
and
▼
buttons are three LEDs marked
+
,
CAL
and
–
. In general the
CAL
LED is used to
show that a variable is set to its normalised value and if not then the others show in which direction it has
been changed or that it is no longer on its CAL value.

Remote/Local Control
The lowest switch selects between Local control and Remote control over DART:
Local
Control is from the front panel itself.
Rem
Control is from the DART system. This requires the use of an external
controller running a suitable programme, which communicates with multiple
racks using the Dartnet protocol.
