SpectraCal ColorBox
Image Calibration Processor
CalMAN Setup Guide
CalMAN takes advantage of the SpectraCal ColorBox processor features to calibrate a video display with
a 10-bit 64x64x64 3D cube lookup table (LUT) for SMPTE video level signals. (NOTE: The ColorBox is not
suitable for creating a 3D LUT at full range/PC levels.) The ColorBox provides six different 3D cube LUTs,
selectable on the front panel LED display. This setup guide assists you in calibrating the ColorBox with
the CalMAN Color Cube workflow.
Recommended CalMAN Workflows:

Color Cube or CalMAN Studio to optimize panel or projector picture controls and to calibrate the
ColorBox grayscale 3D LUT.
Required ColorBox Firmware:

All current firmware
ColorBox Control Connection:

USB A to USB B (printer) cable

USB driver contained in SpectraCal Device Driver Kit
Calibration LUT Creation
When creating 3D calibration LUTs in ColorBox, it is important that the desired LUT is selected on the
ColorBox processor before connecting to the ColorBox through CalMAN. The ColorBox processor, once
connected in the CalMAN software, cannot change its selected LUT. To create multiple LUTs, the
ColorBox needs to be disconnected from the software, and then reconnected after selecting a new LUT
on the ColorBox.
ColorBox Control Connection
The ColorBox is connected to a computer via a USB A to B cable. The ColorBox uses the FTDI USB driver,
which is available in the CalMAN Device Driver Kit, available for download on the SpectraCal website.
To connect a ColorBox for 3D LUT calibration:
1. On the ColorBox, select the desired lookup table (LUT), using the C1 though C6 buttons on
the ColorBox remote. Confirm that the selected number appears on the ColorBox LED.
2. Connect the ColorBox to the CalMAN computer with the specified USB cable.
To change the ColorBox LUT setting:
1. In the CalMAN Display Control panel, Disconnect the ColorBox.
2. Select the desired LUT on the ColorBox.
3. In the CalMAN Display Control panel, click Find Display to reconnect the ColorBox.
