1. System Overview
This manual describes the function of the LE-2n which is an LE-2S or LE-2M
legaliser processing card connected within a nanobox desktop chassis.
1.1 The nanobox chassis
The nanobox chassis has been designed to provide a low cost way of operating a
single legaliser card for stand-alone use without the complex and more expensive
infrastructure of an etherbox 1RU rack mount chassis (FB-9E) and 1RU
operational panel (FB-9). The LE-2n legaliser card is operated by a java software
application for PC or MAC. Connection is via a supplied USB lead.

1.2 The LE-2n Product
This processing card come in two different styles:
1. The LE-2nM, Multidefinition unit, capable of SD and HD operation.
2. The LE-2nS, Standard definition unit, capable of SD operation only.
Apart from the operational standards, the units have the same features and are
both covered within this manual. Within this manual it can be assumed that
references to the LE-2n refer to both styles of processing card. When there are
differences it will be pointed out specifically.
The LE-2n is a full-featured multi-mode legaliser system. The main features of
the LE-2n legalisers are as follows:
•Provides Legalisation of the SDI Input signal with full 10 bit processing
throughout.
•Composite, YUV and RGB colour spaces
•Two Independent SDI outputs for "Legalise" and user controllable
"Legal/Indicate”.
•Adjustable Clipping Levels.
•Adjustable soft clipping knee levels. (RGB and YUV).
•Highly effective overshoot and undershoot suppression on the luminance
signal.
•Integral luma and chroma gain, black level adjustment & hue rotation.
•EBU 2003 standard legalisation settings.
•7.5 IRE or 0 IRE Pedestal.
•6 User Memories.
•Unique severity display mode on monitoring output.
•2 off On-board GPI’s for memory recall.
•Compatible with etherbox GPI/Tallies.

2Setting up the LE-2n
2.1 Associated equipment.
The LE-2n can operate in two modes. Each of these modes is determined by a
factory set internal link option. The modes are:
1. Operation using a soft panel on a PC or a Mac computer.
2. Operation using an eyeheight FP-9 Flexipanel.
Respectively the associated equipment required for operation of the above
modes are:
1. A PC or Mac to operate the softpanel. (User provided) and a USB cable
(Supplied).
2. An FP-9 control panel with an RR-9E rear enclosure (Available from
eyeheight) and a standard ethernet cable cable with RJ-45 connectors
(user supplied) is also required to connect the FP-9 panel to the LE-2n.
The LE-2n will always be shipped in mode 1 ( Soft Panel) unless the
customer specifies otherwise.
DO NOT CONNECT THE SUPPLIED USB/RJ45 CABLE TO THE
FRONT RJ45 LABELLED “PANEL” THIS COULD RESULT IN
DAMAGE TO THE UNIT.
You cannot operate the softpanel and an FP-9E Flexipanel at
the same time.
2.2 Connecting the LE-2n using a soft panel.
This is the way the LE-2n is normally shipped. The data and power connections
are shown in the diagram below. After power up the Status light should turn from
red to green indicating that it is operational in soft panel mode. If the status light
goes orange the system was factory configured for operation with an FP-9 1RU
panel. In the unlikely event that the status light stays red then the system has
found an error and it will need returning to the factory.

2-1 Diagram showing the power and data connections.
THE LE-2n UNIT MUST BE PLACED IN A COOL ENVIROMENT
(ROOM TEMPERATURE IS REASONABLE) WITH ADAQUATE
VENTELATION. DO NOT COVER OR USE IN AN
UNVENTELATED RESTRICTED SPACE.
2.2.1 Installing the software.
The software is provided on a supplied eyeheight USB flash drive
The softPanel application requires no installation itself. Simply run “softpanel.jar”
2.2.2 System Requirements
This software requires Java Runtime Environment version 1.5.0 (Java 5) or later.
This is compatible with Windows and MAC machines.
See www.java.com for the latest version of Java.
USB port. (USB to serial cable is supplied).
Installation
The softPanel application requires no installation itself.
However, it requires three platforms to be in place already:
•Java Runtime Environment (Java 5 or later).
•RxTx serial driver for Java (see below).
•Driver for USB to Serial cable.

eyeheight Unit 34 Park House Watford Business Park Greenhill Crescent Watford Herts GB WD18 8PH
Reg. No. 2855535 Telephone: [phone] Fax: [phone] email: e[email protected]
2.2.3 Java
The latest version of the Java Runtime Environment is available from
www.java.com .
You will need at least version 1.5.0, also known as Java 5.
2.2.4 RxTx Serial Drivers
Since Sun has removed support for serial drivers in Java, we use the open
source RxTx serial drivers.
This means that any client computer will require the files for RxTx.
We use version 2.1-7-r2, which is freely available from www.rxtx.org , and should
be provided with the softPanel application, in a directory called “RxTx”.
Inside the “RxTx” directory, you will find 2 files; one for each supported OS.
You should copy the file for your OS into the Installation Location shown below:
OS File Installation Location
Windows rxtxSerial.dll C:\Windows
Mac OS librxtxSerial.jnilib /Library/Java/Extensions
Users of Mac OS X may receive "PortInUseException" errors reported by the
RxTx drivers when attempting to open a COM Port.
In this case, you should ensure that your user account is granted permission to
use the COM Port, as described below.
2.2.5 Granting a user permission to open a COM Port in Mac OS X
N.B. In Mac OS X 10.5 (Leopard) and above the sudo commands below will
only work if the administrative user account has a non-empty password. (
This means that you must create a user account with a password to allow
installation. This is something that has recently been enforced by apple.)

2.2.6 USB to Serial Drivers
Drivers for the USB cable are available for Windows and Mac from the
manufacturer’s website, at http://www.ftdichip.com/Drivers/VCP.htm.
Once you have successfully installed the USB to Serial cable, you will need to
confirm what port name / number it is listed as.
You can do this in Windows as follows:
1. Access the System properties, via:
[Control Panel > System]
Or
[My Computer > Right-Click > Properties]

The display colour is based on a traffic light system of green, amber, and
red.
Hover the mouse over the control to see an information tooltip.
2.3.3 Status Bar
Generic GUI component, for conveying information to the user.
In normal use, the status bar will display the Host Alias of the device, but it is also
used to display error messages and status updates.
2.3.4 Display Buttons
The four buttons, labelled A, B, C, and D act both as separate menu displays,
and as larger combined displays, depending on context.
They also act as buttons; performing an action when clicked. This action will
depend on what is displayed on the button at the time.
For more info, see Menu Navigation.
2.3.5 Rotary Controls
In normal use, the four rotary controls correspond directly with the four Display
Buttons; each to the display above it.
When a rotary control is not enabled, its marker will be grey.
When it is in use, the marker will be white, and it will respond to the mouse
pointer, when hovered over it:
Not enabled Enabled Mouse

2.4.3 Double Or Triple Parameter Adjustment
A red menu is one in which there are two or three adjustable parameters. In this
case it is necessary to first select the menu by pressing the red Display Button.
When the red button is pressed it will turn green, and either two or three of the
Rotary Controls will flash, indicating that the respective Rotary Control will
operate a corresponding parameter.
2.4.4 Information Display
A yellow menu is one in which only information is displayed.
2.5 Connecting the LE-2n using an FP-9.
The LE-2n is normally shipped for operation with a soft panel. If you have
specifically asked for the system to operate with a flexipanel then it will be
shipped this way. The control and power connections are shown in the diagram
below. After power up the Status light should turn from red to orange indicating
that it is operational in FP-9 panel mode. If the status light goes green then the
system was factory configured for operation with a soft panel. In the unlikely
event that the status light stays red then the system has found an error and it will
need returning to the factory.

The Ethernet cable must be <2M long or you may experience fading of the FP-9
display due to voltage drop from the power supply in the LE-2n. If you wish to
mount the FP-9 panel very remotely (up to 150 Metres) then set the power switch
on the RR-9 (Rear box for the FP-9) to “LOC” (Local) and use the power supply
supplied with the RR-9 to power the panel.
2.5.1 Flexipanel controls.
Figure 2-3 Flexipanel (FP-9) controls.
2.5.2 Device Buttons.
There are 8 grey device buttons. These switch between the currently selected
processing cards installed in the etherbox. It is also possible to select cards in
another chassis if the I-Bus is connected to the other chassis.
2.5.3 Menu Navigation.
There are two ways to navigate from menu to menu.
1. Using the NEXT and PREV buttons. These are for “Flat” menu structures.
The NEXT and PREV LEDS will flash while further menus are available.
2. Using a GOTO ANOTHER MENU LCD button (as below coloured orange).
This is more common and will take you straight to a relevant set of menus.
Examples are the Play and UTILS menu’s shown on Figure 8.
