readers to your 4025. 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 4025.

2.12.2. Verifying Communications between the 4025 and the Reader

Once the KeyKode reader has been installed on the telecine, and
connected properly to the 4025, you are ready to verify that the reader is
reading properly, and that the two units are communicating.
Put a piece of bar-coded film stock onto the telecine, and put the telecine in
Play. You should observe that the reader unit is reading the KeyKode, as
indicated on the reader electronics unit. Usually a beep or tone from the
reader electronics unit indicates that it is reading successfully. Also, the
KKODE LED on the 4025 front panel should blink On each time a barcode
data record is sent to the 4025.
Once you have verified proper communications, proceed to learning the

procedure for the reader unit and connections to the 4025 as outlined in
the previous sections. Chapter 5 contains some additional trouble-shooting
information that you may find helpful.
2.12.3. Learning the Mechanical Offset Between the Reader Head and
the Telecine Gate
When installing the pickup head on the telecine, there will be a fixed
mechanical mounting offset between the KeyKode reader head and the
actual film frame in the gate.
installation to installation, but will be fixed for any given installation. Care
should be taken when installing and removing the reader head from the
telecine, so that the same offset can be maintained. The angle of the
reader head, when it is mounted on the telecine may affect the head to
gate offset, and the reader reliability. In general it is desirable to align the
reader head such that the angle that the film enters and leaves the reader
head is approximately the same. It may be desirable to make an alignment
mark on the telecine, to facilitate re-installation, should it become
necessary to remove the reader head.
Head offset values are saved in non-volatile memory when power is
removed. The 4025 maintains separate head offset values for 16 mm and
35 mm film types for each transfer speed.
