Addendum to Spatial Light Modulator (SLM) User’s Manual Rev. 1.5
Document number MD15326-1.5
November 11, 2010
This document lists additions and changes to the SLM User’s Manual brought about by the introduction of the new,
smaller SLM-128 enclosure. The SLM-640 enclosure remains unchanged. It also lists steps necessary to properly install
the USB drivers for Windows 7 (32-bit and 64-bit).
Section Page Change or Addition
1.3 10 Controls and Indicators
USB LED has been removed
TTL/Sync Trigger (BNC) has been changed to an SMA connector
Power Jack 2.1 mm connector is unchanged, but the supplied universal power adapter is
now a +5V unit instead of a +24V unit. A new overvoltage circuit prevents damage to the
SLM if a higher-voltage power supply is accidentally used.
1.4 11 Start-Up Guide
There is no longer a separate USB LED that lights when the USB cable is plugged in to
the SLM.
See the drawing of the new SLM-128 (MA 20707, Assy, SLM 128, Mini). The SLM-640
remains unchanged.
Software installation under Windows® 7 (32-bit or 64-bit)
The current software installer (version 1.3.4) was written for Windows® XP Professional
(SP-2 or later). While CRi does not expressly support the Windows® 7 operating system
yet, the following steps enable you to install USB drivers compatible with Windows® 7.
1. IMPORTANT: Do not plug the SLM into the computer until you are instructed to
do so.
2. Go to http://www.ftdichip.com/Drivers/VCP.htm and download the most recent
driver package for your operating system.
3. Unzip the downloaded file and save the contents to a folder on your desktop or
another location where you can find it again.
4. Run the CRi SLM Setup.exe program.

5. When the installer is finished, plug the SLM into the computer. You will receive a
Windows error message that not all the drivers were properly installed. Don’t
worry, this is normal.
6. Go to the Device Manager and locate Other Devices >> USB <-> Serial.
7. Right-click on USB <-> Serial and choose Update Driver Software
8. Click “Search automatically for updated driver software”. Windows should
automatically find the folder containing the latest USB drivers and install them. If
it does, go to Step . If it does not, proceed to Step 9.
9. Click “Browse my computer for driver software”, navigate to where you
previously saved the contents of the USB driver package, and click Next.
10. If Windows warns you about verifying the publisher of the software, click “Install
this driver anyway”.
11. Go to the Device Manager and right-click on Other Devices >> USB <-> Serial
Port.
12. Click “Browse my computer for driver software”, navigate to where you
previously saved the contents of the USB driver package, and click Next.
13. If Windows warns you about verifying the publisher of the software, click “Install
this driver anyway”.
14. At this point, in Device Manager the Ports (COM & LPT) category should appear.
15. Since the SLM is plugged into your computer, a numbered COM port will also
appear. Make a note of the COM number.
16. You can now launch the CRi demo program SlmGui.exe located in C:\Program
Files (x86)\CRi\SLM and enter the COM number for the SLM. After a moment,
the program will recognize the SLM.
