Quick Start Guide

Lumagen Radiance

The Lumagen Radiance™ processors dramatically improve any display’s picture quality, with superior,
industry-leading Radiance processing. They also provide controls to calibrate 11 or 21 point grayscale
and either standard CMS primary and secondary color points, or a 3D cube lookup table (LUT) for
SMPTE video level signals. The Radiance XD, Mini, XE, and XS provide a 125 point 5x5x5 LUT. The
Radiance 20xx series provide a 729 point 9x9x9 LUT. The Radiance 21xx series provide a 4913 point
17x17x17 LUT.

Included Parts

In the Radiance shipping box you will find:

 Lumagen Radiance processor
 Power supply
 Remote control
 RS232 serial null-modem 1 meter cable
 USB to RS232 serial adapter

Radiance Firmware

 Any recent version for grayscale and standard CMS calibration.
 Version 091112, or newer, for 3D LUT calibration

Firmware updates can be found at http://www.lumagen.com/testindex.php?module=updates

To update the Lumagen firmware, connect the supplied RS232 (null modem) cable between the RS232
port on the Radiance and your PC, unzip the update file from Lumagen, and run the update program.
Select the appropriate RS232 port, select the 57600 baud rate, and click Start. While the update is being
performed, the Lumagen will display “Update in Progress” on its video output.

Note: For connecting to and controlling a Radiance with computers that do not have an RS232
connection, SpectraCal recommends the FTDI USB to RS232 converter, supplied with the unit. Thorough

CalMAN Setup Guide

The Lumagen Radiance processors provide controls to calibrate 11 or 21 point grayscale. They also
provide controls to calibrate the standard CMS primary and secondary color points, or to calibrate a 3D
cube lookup table (LUT) for SMPTE video level signals. (NOTE: The Radiance models are not suitable for
creating a 3D LUT for use with full range/PC levels.)

Recommended CalMAN Workflows:

 HT Advanced or SI Advanced to optimize panel or projector Picture controls.
 HT Advanced or SI Advanced to calibrate Radiance grayscale RGB balance and standard CMS, or
 Color Cube or CalMAN Studio to calibrate Radiance grayscale RGB balance and 3D LUT.

Required Radiance Firmware:

 Any recent version for grayscale and standard CMS calibration.
 091612, or later, for 3D LUT calibration

Radiance Control Connection:

 21xx series: USB cable (serial cable can be used, at slower speed)
 Older models: DB-9 female to DB-9 female null-modem RS-232 cable (pin2 - pin3, pin3 - pin2)

Radiance RS-232 Echo must be On
Menu > Other > I/O Setup > RS-232 Setup > Echo: On

Radiance Setup Process:

1. Connect the Radiance to the CalMAN computer with the specified cable.

2. A USB to Serial adapter, if used, needs to include a data buffer, such as the certified adapter

available on the SpectraCal web site.

CalMAN Grayscale and CMS Calibration:

To connect a Radiance for grayscale calibration and standard CMS primary/secondary color calibration:

1. In the Radiance menu, set the 3D Color Gamut Options to Disabled and 8 Points.

o Menu > Output > CMS’s > CMSx > Color Gamut > Options > Enabled; No
o Menu > Output > CMS’s > CMSx > Color Gamut > Options > Points; 8

2. In CalMAN, load the "SI Advanced" workflow.

3. On the CalMAN Settings tab (gear icon), under Workflow Basic Options, select Video (16-235)

[SMPTE legal].

4. Proceed through each step of the workflow in the normal fashion, using the following notes for

guidance on the indicated workflow pages.

5. On the Hardware Connect page, click the Find Source button, select “Lumagen – Radiance

series,” then click Connect.

6. On the Hardware Connect page, click the Find Processor/Display button, select "Lumagen –

Radiance CMS,” then click Connect.

7. On the Dynamic Range page, adjust the display’s black level/Brightness control to 16.

8. Skip the Grayscale - 2pt page (no advantage when doing the following multipoint AutoCal).

9. On the Grayscale/Gamma page, click the AutoCal button and wait for the AutoCal process to

complete.

10. On the CMS Calibration page, click the AutoCal button and wait for the AutoCal process to

complete.

DONE – Radiance Grayscale and CMS calibration is complete.

CalMAN Grayscale and 3D LUT Calibration:

CalMAN can calibrate the 3D LUT in the Radiance with a direct USB control connection. To produce an
optimized 125 point 3D LUT calibration file and automatically load it into the Radiance:

1. In the Radiance menu, set the 3D Color Gamut Options to Enabled and 125 Points.

o Menu > Output > CMS’s > CMSx > Color Gamut > Options > Enabled; Yes
o Menu > Output > CMS’s > CMSx > Color Gamut > Options > Points; 125

Radiance CMS Luminance Level Setup

2. In CalMAN, first load the "SI Advanced" workflow.

3. On the Hardware Connect page, click the Find Source button, select “Lumagen – Radiance

series,” then click Connect.

4. On the Hardware Connect page, click the Find Processor/Display button, select "Lumagen –

Radiance 3D LUT fw 091612 or later,” then click Connect.

 Skip to the CMS Calibration page:

5. On the SI Advanced workflow CMS Calibration page, first click the Read Series button to

measure the performance of the primary and secondary colors.

6. Click through the color level select tabs for the six primary and secondary colors to note

which color has the lowest DeltaL.

7. Click the Read Continuous button and equally decrease the Radiance CMS White Level SubR,

SubB, and SubG controls. Decrease the White Level controls equally, while watching the
DeltaL measurement for the lowest color, until it reaches the 0 point on the DeltaL chart.

 You are now done with the SI Advanced calibration workflow.

Radiance Grayscale and 3D LUT Creation

1. In CalMAN, load the "Color Cube (3D LUT)" workflow.

2. Proceed through each step of the workflow in the normal fashion, using the following notes

for guidance on the indicated workflow pages.

3. On the RGB Adjust page, under the RGB Adjust Levels selection, select “2 Point 30, 100%.”

Click Read Continuous and adjust the display’s RGB Gain controls for RGB balance at 100%.
Adjust the display’s RGB Offset/Bias controls (if provided) for RGB balance at 30%.

4. On the 1D Ramp LUT page, click the AutoCal action button in the lower right to optimize

calibration of the display’s grayscale and gamma. (This step is not required for a 20xx and
21xx series model, since a 17 point grayscale calibration is done within the following
17x17x17 point LUT calibration.

5. On the 3D Cube LUT page, click the AutoCal (circling arrows) button at the right end of the

meter action buttons. The AutoCal Setup dialog then appears (see below).

6. Under Calibration Type, select the desired type of 3D LUT calibration process.
 IR Profile (time based): Creates the best quality display calibration 3D LUT possible

in the selected period of time. You select how much display quality you have time
for, from 30 minutes to maximum display quality (6,000 points max). Uses
Intelligent Resolution Profiling to search out the most nonlinear color space areas
and correct those first.

 IR Profile (point based): Creates the best quality display calibration 3D LUT possible

with the selected number of measurement points (1,000 - 10,000 points). Uses
Intelligent Resolution Profiling to search out the most nonlinear color space areas
and correct those first.

 Lightning LUT: Creates a display calibration 3D LUT in five minutes or less. Produces

a very high quality result on professional displays with moderate linearity. Displays
with significant nonlinearity may produce marginal results.

7. Under Video Range, select “SMPTE (16-235)” if you are calibrating a video display that clips

or compresses signals above reference white, as tested on the CalMAN Dynamic Range
page.

8. Click OK.

Upon completion of the AutoCal 3D hardware LUT calibration process, CalMAN automatically loads the
optimized LUT calibration data into the Radiance.

DONE – Radiance 3D LUT calibration and setup is complete.
