3. SYSTEM OPERATION
3.1 LOCAL
CONTROL
3.1.1 Start up
Local control and monitoring of the V1682 is done through the front panel with its eight character
LED display and three control buttons
Select
,
σ
and
τ
. There are three LEDs which also contribute
to the status indication; these are labelled
+
,
Cal
and
–
.
After power up the display will start at the top level and show the unit type and any options that are
included. These options are not the same as the plug-on modules for the audio I/O. The V1681
has no options, so the display should show
VALID RD.
3.1.2 Menu Control
The
Select
and
σ
and
τ
buttons are used to manoeuvre around the menu system. The menu
structure has five levels and the
Select
button is used to go up and down the structure. The
σ
and
τ
buttons are used to move between selections or to adjust a parameter depending on which sort of
menu is displayed. The five levels are as follows:
Sleep
Display is blank (except for Banner warnings).
Top Level
As above, e.g.
VALID RD
Main Menu
The Main menu items, such as
MEASURE
,
AUDIO
etc. These items are
all in Upper Case.
Sub Menu
Menu items under each main heading, such as
Aud I/P
or
Mux Grp
under the
AUDIO
main menu. These items are all in Sentence Case
(generally lower case but with upper case first letters).
Parameter
The lowest level under the Sub Menu, and used to actually adjust a
parameter, or view a status. The display will depend on the actual
parameter and usually offers a selection of options e.g.
Analog / Group
1 / Group 2
.There is usually a title to describe the variable and a small
icon in the left hand character position, but 8 characters cannot provide
for a detailed description.
Many of the sub menus depend on which audio I/O sub modules are fitted. For example the
Calibration functions of the analogue audio ADCs and DACs under
CALIB
do not appear unless a
suitable sub-module is fitted.
To move down a level just press the
Select
button briefly; then press either the
Select
button again
to go down another level or the
σ
and
τ
buttons to move around the options within a level.
To move up a level press and hold the
Select
button for about half a second which will move up one
level. If you continue to hold the
Select
button then it will move up a level every half a second until
it reaches the Sleep level (one above the Top Level).
A complete list of all the menus is given in Section 8
