8. Getting started
The mask image resolution should be a little bigger than half of the camera resolution:
• Canon EOS 1000D: 1953 x 1301 pixels;
• Canon EOS 1100D: 2176 x 1437 pixels.
It must contain only black and white regions. A black region is used to hide the artifacts and the white regions of the mask will not
hide the image. All mask files must be saved as .png files at the following location on the MCU: C
:\Program Files\Barco\XDS\re-
sources\autoalign\maskImages
In case of XDS RACU Diskless server, all mask files must be saved on a storage server provide by the customer at the following
location: \
\<MCU hostname>\shared_folder\<MAC address>\autoalign\maskImages where <MCU hostname> is the diskless MCU
server name, shared_folder is a folder on the diskless server and <MAC address> is the MAC address of diskless MCU server.
To know the MAC address o f your MCU co nnected o ver the n etwork, you may n eed to follow the steps mentioned below
1. Go to Start > Connect to > All Connections
2. Select your Local Area Connections right click it and select Status
3. In the Local Area Connection Status, select Support tab and click Details
4. The MAC address is the Physical Address listed in Network Connection Details.

8.7 ECR calibration
This section only applies to projec tors that su pport E CR Calibration (e.g. SIM 7 s eries, SIM 10).
On S IM 5W a lens with ECR also exists, bu t this o ne can not be re-calibrated.
Calibrate ECR
The calibrate ECR function creates a table which indicates the projector light transmission versus its aperture opening. This table
is stored in the lens memory and is read by the projector on startup to be used in conjunction with the CCD for Time of Day (TOD)
operation
By default, a look-up table is stored in the lens during production. If you suspect that your aperture control is erratic or does not work
well, you should use calibrate ECR and create a new LUT. The calibrate ECR function creates a table which measures the projector
light transmission versus its aperture opening.
ECR calibration must be performed in a perfectly dark environment. Any ambient light or stray light will lead to a bad LUT.
How to start the ECR calibration process?
1. Open the main page of the XDS RACU user interface.
2. Select a projector.
3. Navigate to Projector > Calibration and press it.
