DMC Repair Manual Camera Overview

Overview

This section of the Repair Manual gives an overview of the Digital Microscope Camera (DMC).

It only provides the necessary information pertaining to features and specifications for the

camera.

Note: For detailed information pertaining to setting up the camera, installing and starting its

software, assigning SCSI ID's and checking SCSI connections, and using application

software, refer to the DMC User Guide.

This camera (Figure 1-1) is used to capture high-quality digital color images from light

microscopes and other optical instruments. It uses a unique, million-pixel, 12.5mm CCD

(charge coupled device) to capture pictures with up to 16.7 million colors. The camera

transfers these pictures in seconds to an IBM-PC-, PowerMac- or PowerPC-compatible

computer as high resolution (800 x 600 pixels) or super-high resolution (1600 x 1200 pixels)

TIFF images.

Figure 1-1. Digital microscope camera

Using the Microsoft Windows or PowerMac/PowerPC software provided with the camera, you

can display a viewfinder image on a computer screen, choose resolution and other options,

enhance color balance, brightness, contrast and sharpness, then transfer the picture to an

image-processing application or a disk drive.

The camera has a SCSI-2 connection requiring no frame-grabber or other special hardware or

software. It also includes a SCSI-2 adapter board for adding a SCSI port to a computer.

Using a standard .63, 1:1, or larger C-mount adapter, the camera attaches easily to

microscopes for most types of transmitted-light and reflected-light microscopy.

The camera also features a tripod mount and Xsync connection for use with standard C-mount

lenses on a copystand.

DMC Repair Manual Camera Overview

Features

Table 1-1 list and describes the features of the camera.

Table 1-1. Camera Features

Feature Description

Power Switch Turns the camera on and off.

Strobe X-sync Connector Connector for electronic flash, if used with the camera.

Termination Selector Turns camera SCSI termination on or off.

SCSI Connector One (1) 25-pin standard SCSI connector. Connects to

the host computer SCSI port via the provided SCSI

cable.

SCSI Selector Sets the SCSI address of the camera. Preset at 4.

Note: Do not use 7 or 0, which are customarily

reserved for the host computer and for

PowerMac/PowerPC hard drives.

If possible, avoid SCSI ID 3, which is often

used for internal CD-ROM drives.

Power Connector Connection for the AC power adapter.

WARNING

Always connect the camera to AC power when it is

connected to the computer. If the camera or any other

SCSI device turns off while connected, it could corrupt

data on your hard disk.

Power Indicator LED Lights green to indicate that the camera is powered on.

Feature Description

Not Shown in Figure 1-2:

Power Adapter Provides surge-protected 5.8 Vdc, 3-amp power for the

camera from 110-240 Vac power outlets.

SCSI Cable (2 meter) Connects the camera to a PowerMac/PowerPC

and DB25/50 Pin computer or the PC SCSI-2 adapter.

Centronics Adapter

SCSI Host Adapter Adapter board for adding a SCSI port to a computer for

communicating with the camera and other SCSI

devices.

Software Diskettes TWAIN driver (for Windows 95 and Windows NT only),

Plug-in software for PowerMac/PowerPC systems, and

Polaroid DMC Direct camera utility software for

Windows 95, Windows NT, and PowerMac/ PowerPC

systems.

DMC TWAIN Driver :

Using the TWAIN driver requires an image-processing

application (not provided) compatible with the TWAIN

specification.

DMC Direct Software:

If you do not have an image-processing application

compatible with TWAIN, DMC Direct software can be

used to transfer pictures from the camera to the host

computer.

Tripod Mount Standard mount for attaching the camera to a

copystand or tripod.

DMC Repair Manual Camera Overview

Table 1-1. CameraFeatures (Con't)

Feature Description

C-mount Accepts standard C-mount adapter for attachment to

microscopes, other optical instruments and C-mount

lenses.

Note: Attaching the camera to amicroscope requires .

a 63 or 1:1 C-mount adapter (not provided)

compatible with your microscope.

Do not use a .5 C-mount adapter, because it

will produce image vignetting (dark corners).

Refer to the applicable microscope’s instruction

manual or contact the microscope

manufacturer for more information about

C-mounts.

Caution

Before attaching a C-mount adapter or lens to

the camera, verify that the threaded end of the

adapter does not exceed 0.195 inches (5mm).

Longer C-mount adapters may damage the

camera.

Cautions

Electrostatic - Digital Microscope Camera circuitry can easily be damaged by small

Discharge static discharges. Always use an anti-static mat and an ESD wrist-

Warning strap when disassembling, assembling or repairing the camera with

the bottom extrusion removed.

Inspection and - Whenever disassembling a Digital Microscope Camera for parts

Cleaning replacement, inspect it for dust and debris. If necessary, clean the

camera to assure that dust in the optical path does not degrade its

performance.

Connectors - The connectors in the Digital Microscope Camera have locking tabs

(Figure 2-1) which secures the flex cable in place. To remove a flex

cable, first pull back the two (2) locking tabs and pull the flex cable free

of the connector. To install a flex cable, align it in the connector and

make sure it is fi\ully seated befor pushing in the two (2) locking tabs.

Figure 2-1. Typical flex connector

Screw - Do not reuse the front and rear panel screws. Always use new

Replacement screws (PH PA 4-40 x .75) when reinstalling the front and rear

(Front /Rear panels. These screws are coated to prevent them from backing

Panels) out.
