STH-MDCS USER’S MANUAL 2001 VIDERE DESIGN

2 Quick Start

The STH-MDCS/-C comes assembled, the interface module mounted to the

imager module. The module comes with lenses dismounted.

To set up and test the STH-MDCS/-C, you will need the following:

1. Pair of C-mount lenses, for 1/2” or larger imager (included

with the STH-MDCS/-C kit).

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

compliant.

3. 1394 6-pin cable.

4. Capture software or Small Vision System installed on the host

computer.

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

Section 7.1. Install the Small Vision System software (see Section 7.2).

This is the not-so-quick part of the Quick Start.

Screw the lenses into the mounting holes on the stereo head. Be careful not

to force them initially, as you can cross-thread the lens mount. Snug them

down, but do not tighten excessively.

Plug one end of the 1394 6-pin video cable into the 1394 jack on the back

of the STH-MDCS/-C, and the other into a 1394 port on the host PC. Note:

for PCMCIA cards, and laptops with a 4-pin Sony iLink port, an external

power supply and adapter are necessary to convert to a 6-pin (signal +

power) 1394 plug. Most PCMCIA cards come with this adapter.

Start the SVS main program, smallv(.exe) or smallvcal(.exe),

on the host computer. You should see a screen as in Figure 2-1. The

message window should indicate that the STH-MDCS interface is present.

If not, go back to software installation (Section 7.2), 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 stereo

head, 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 stereo video, press the Continuous button. Left and right images

should appear in the application windows. If the message “Image timed

out” appears, then there is a problem with the IEEE 1394 drivers; please see

Section 7. If the images are too light or too dark, you can open the manual

iris of the cameras, or change the exposure and gain settings (Section 6.3).

Images can be saved using the File menu.

A more complete description of the video capture program is in Section 6.

The SVS programs are described in the documentation that comes with that

Figure 2-1 SVS main program window.
