About the Datacolor 245™
The Datacolor 245 provides a new, solid-state approach to 45º/0º measurement geometry.
It employs a unique, dual-beam optical design, uses a pulsed xenon lamp and has a sealed
optical path for improved repeatability and long-term stability. 45º/0º instruments are used
for quality control applications when both color and appearance features are being
evaluated.
The Datacolor 245 includes the following standard features:
•Dual-beam measurement using pulsed xenon light source
•Datacolor proprietary high-end sensor
•Conformance to ASTM E1164 Standard Practice for Obtaining
Spectrophotometric Data for Object-Color Evaluation
•Drawer for accessories
•Datacolor world wide support

Safety Warnings
Light Source
Do not stare directly into the open port located in the front door panel when the
measurement is in progress. Staring directly into the light source can result in eye
discomfort similar to that of staring at a camera flash.
Side Vents
Vents are included along each side of the instrument to facilitate air circulation. HIGH

Accessories
All models come with the following standard accessories:
•Six foot power cable
•Serial cable with connectors on either end
•USB cable
•Black Trap
•White Tile
•Green Tile
In addition, an optional accessory drawer is available with the unit.
Calibration Tiles
A black trap, white tile and green tile are provided with Datacolor instruments.
•The black trap and white tile are used each time the instrument is calibrated.
•The green tile is used to perform an optional diagnostic test.
Calibration Data
The calibration procedure uses white data that must be installed on the system. It is data
unique for the white calibration tile, and is provided on either a diskette or a CD. It is
included with the instrument accessories:
NOTE
The serial number on the back of the white calibration standard should match the serial
number on the instrument.
Aperture Plates
The Datacolor 245 is a single aperture instrument. Refer to Appendix, Features by Model
for the aperture specification.

Cable Installation
Instrument Cables
WARNING
BE SURE TO TURN OFF THE POWER BEFORE WORKING WITH ANY CABLES.
The Datacolor 245 requires the use of two cables, a power cable and either a serial cable
or a USB cable, to connect the instrument to the computer.
WARNING
Read "Electrical and Environmental Requirements section before connecting your
instrument.
The connections for these cables are found on the back of the instrument.
Power Cable
A six-foot power cable is provided with the instrument.
Power is supplied to the back of the unit via a 3-prong male connector.
6 •Cable Installation Datacolor 245™ User's Guide
Communications Cable
The instrument is connected to a computer through either a serial port or USB port:
1. Plug the female end of the power cord into the power receptacle on the rear
panel of the instrument. Insert the plug into a standard AC outlet.
2. Connect the male connector on the instrument cable to the appropriate female
connector on the rear panel of the instrument.
3. Connect the female connector on the instrument cable to a communications port
on the back of the computer.
4. Tighten each connection securely to ensure proper signal.
NOTE
If there is more than one serial port on the computer, make a note of the port
being used. You may need to enter this information into the program.
See USB Driver Installation in this guide for detailed instructions regarding
the software installation. See the Appendix for a description of the RS-232C
connector pin assignments.
