Page 5: Chapter 1 - Introduction
This guide contains installation, configuration and operation instructions for the Truelight SDI unit. It also contains a guide to preparing and loading colour cubes onto the unit. Troubleshooting help can be found in the FAQs section of this guide. Truelight SDI User Guide... -

Page 7: Terminology
Since extra dimensions increase the total number of input value combinations substantially, practical 3D LUTS always subsample the input space, often on a regular cubic lattice. In colour management, 3D LUTs are sometimes referred to as cubes. Truelight SDI User Guide... - Page 8 Truelight text file format specification to input the LUT values directly (as described in the Truelight Cube Format document). Also, when a profile is selected for loading onto Truelight hardware (like the Truelight SDI unit) it is communicated to and stored on the unit as a cube.

Page 9: Chapter 2 - Installation
Contact Truelight Support for assistance (truelight-support@filmlight.ltd.uk). Installing the Truelight SDI hardware The Truelight SDI hardware consists of a 1U rack-mountable unit. It should be bolted into a standard 19” rack using appropriate screws and allowing sufficient space above to provide adequate ventilation. -
Page 10: Connectors
Connect these ports to the SDI IN ports on your display device. – Ethernet connection The ethernet port allows Truelight SDI to be controlled over a standard 10/100BaseT network. This connection provides full control over the unit. It should be connected directly to the software host, or to an appropriate hub or switch within your network. -
Page 11: Connecting To A Network
Installing the Truelight SDI hardware Connecting to a An ethernet connection is provided to connect the Truelight SDI unit to a network. In a typical setup the connection would be made via a switch or hub, but it is also possible to network make a direct connection to the Truelight software host. -
Page 12: Assigning A Static Ip Address
Truelight software host via serial port 2 and running the Truelight application. Once connected, the IP address is read via the serial link and automatically displayed in the Hardware panel in the Truelight application (see Connecting to the Truelight SDI unit on page 9 for details). -
Page 13: Chapter 3 - Configuration
Truelight profiles. Full details of display calibration can be found in the guide, Calibrating your display with Truelight. The Truelight SDI box contains 15 cube slots that must be programmed from a Mac or Linux system running the Truelight software. Note that in order to create custom cubes using Truelight, or load custom cubes created in another system to the Truelight SDI unit, an appropriate license must be installed on this machine. - Page 14 If it fails to connect, check that the cables are plugged in correctly. If you are using the ethernet connection, check that you can 'ping' the box—see Section 5 - Troubleshooting for help. The current box settings and all cube names are automatically read and displayed in the Hardware panel. Truelight SDI User Guide...

Repeat this procedure for each of the slots that you want to (re)program. Removing cubes If you want to delete any of the cubes from the Truelight SDI unit, select the appropriate slot from the list in the Cube Transform section, and then click Delete cube. -
Page 16: Creating A Gamut Alarm Cube
Programming the colour cube slots Creating a gamut The cubes in the Truelight SDI unit are arranged in pairs—the second cube in a pair is often a gamut alarm version of the first (see Selecting cubes on page 17). Gamut alarm cubes are alarm cube generated from a profile just like other cubes in the SDI unit. -
Page 17: Setting The Hardware Modes
If you have cubes installed that were created in different modes then it is recommended to include an appropriate reference (for example ‘RGB-Scaled’ or ‘YCrCb-Unscaled’) as part of the file name for the profile used to generate the cube. Truelight SDI User Guide... -

This toggle button turns the scaling function on or off. This function can also be controlled via the Java remote control—see Remote control on page 19. Panel Lock This toggle button locks the front panel buttons preventing local operation. This function can also be controlled via the Java remote control. Truelight SDI User Guide... -

Page 22: Bypass Mode
Legalizer The Truelight SDI unit has the ability to ensure that only legal video is displayed (that is, output values are limited to the 64-940 range for 10-bit video). This is achieved by clipping the output RGB or luminance/chroma values to this range. Note that the use of the legalizer depends on the nature of the video being fed into the unit and also on how the output data is to be subsequently processed. -
Page 23: Information Display
Remote control The Truelight SDI unit can be controlled from any browser on the network using a Java applet. To access the unit it must be connected to the network via its ethernet port—see Installing the Truelight SDI hardware on page 5. - Page 24 ‘X’ through it. Note that the remote control has no facility for downloading cubes into the box—for details of loading cubes into the Truelight SDI unit refer to Programming the colour cube slots on page 9.

64-940 range will effectively be clipped. Panel Lock When enabled, the front panel buttons on the Truelight SDI unit are disabled preventing local operation. In this state, the message ‘PANEL LOCKED’ appears in the LCD. -

Truelight root by selecting Manage Calibrations from the Tools menu in the Truelight window. Performing a To copy all the cubes in the Truelight SDI unit, click the Archive button in the Synchronise section of the Hardware panel: backup Figure 4-5: Synchronise options All cubes on the box are written to a BZ2 zip file. -

5 - Troubleshooting FAQs How do I find out the IP address of my Truelight SDI unit? The IP address is displayed on the LCD for a few seconds when the unit is turned on. If no IP address has yet been assigned, let the unit boot and then power-cycle it by unplugging the 5V power plug and then plugging it in again after a couple of seconds. -
