INSTALLATION
2.12.7 Verifying the Connections to a Philips Telecine
When you have completed the basic telecine connections, you will need to
verify the frame accuracy of the basic system using the procedure in
section 2.11.7. Once you have verified the basic connections, you may
proceed to the KeyKode reader installation.
If you do not verify the frame accuracy of the system at this time, the
accuracy of your system with KeyKode will also be affected.
With the introduction of machine readable edge numbers by Eastman
Kodak and other film stock manufacturers, (referred to as KeyKode
numbers), the edge number information can now be read by a bar code
reader. This eliminates the tedium and human error or manual entry, and
provides an absolutely accurate identification, entry and tracking of film
edge numbers.
The 4025TR Film Footage Encoder interfaces to reader systems from
several manufacturers. These KeyKode readers are self contained units
and consist of a bar code pickup head, and a decoder device. The pickup
head transforms the optical dark and light bar code into electronic signals
and is designed specifically to mount on the telecine feed roller just before
the film enters the gate. The decoder receives these electronic signals
from the pickup head, and sends the decoded KeyKode number via a serial
link to the Film Footage Encoder, for automatic placement into the time
code.
2.13.1 Hardware Installation
A nine pin female 'D' connector (AUX I/O) is provided on the rear panel for
connection to an external KeyKode reader. Most of the KeyKode readers
use RS-232-C level signals to communicate with the 4025TR.
Evertz 4015 users note that this is NOT the same connector used to connect
the KeyKode readers to the 4015 Film Footage Encoder.
Cable WA-C67 may be used to connect Evertz, RIM and Cinema Products
readers to your 4025TR. Alternately, you can wire your own cable using
the wiring diagrams shown in Chapter 7.
Consult Chapter 8 for specific information about installing your specific
reader system and connecting it to the 4025TR.
