2 Quick 

Start 

The MDCS2 comes assembled, with 6.0 mm lenses as standard.  To set up 
and test the MDCS2, you will need the following: 

1.

 

Host computer with a 1394 PCI or PCMCIA card, OHCI 
compliant.  

2.

 

1394 6-pin to 6-pin cable. 

3.

 

DCAM software installed on the host computer.  This software is 
provided via download from the web, using a password-protected 
web page. 

Install the 1394 host card, if necessary, according to the directions in 
Section 

Error! Reference source not found.

.  Install the DCAM software.  

The MDCS2 has a single IEEE 1394 port, for plugging in an IEEE 1394 
cable. Plug one end of a 6 pin – 6 pin IEEE 1394 cable into the port, and 
the other end into any port of the host card.  See Section 6 for more 
information about the IEEE 1394 interface, and for information about 
supplying power with a laptop. 

Start the video capture program, 

dcam640(.exe)

, on the host computer.  

You should see a screen as in Figure 2-1.  The message window should 
indicate that there is a MDCS2 present.  If not, go back to software 
installation (Section 

Error! Reference source not found.

), and follow the 

instructions for configuring the correct capture library. 

Pull down the Input chooser, and select the 

Video

 option.  If everything 

has been set up, the driver software will recognize and configure the 
MDCS2, and a success message will appear in the info text window.  If not, 
the Input chooser will go back to 

None

, and an error message will appear 

in the info window.  Please see Section 7 for troubleshooting. 

To view video, press the 

Continuous

 button.  An image should appear in 

the application window.  If the message “Image timed out” appears, then 
there is a problem with the IEEE 1394 drivers; please see Section 7.  After a 

few seconds, the images, which are initially dark, should lighten as the auto 
exposure mode adjusts to ambient lighting (Section 7.3).  Images can be 
saved using the 

File

 menu. 

A more complete description of the video capture program is in Section 7.  
The DCAM programs are described in the documentation that comes with 
that software.  It is helpful to review Section 7 in conjunction with the 
MDCS2 software documentation.
