KEYKODE READER INSTALLATION
The Evertz KeyKode combination reader head system is capable of
reading from 16mm and both edges of 35mm film.
versions of the head are available for those who only deal with one film
gauge. The floating head is designed so that it is self-aligning to the film
path. This is especially critical in 16mm applications. All that is necessary
is to locate the bracket so the film passes approximately over the rollers.
The head then follows the exact film motion, finding the optimal position for
KeyKode reading.
The mounting bracket is typically fastened to the collar of the last roller on
the telecine before the film enters the gate. The reader head is fastened to
the mounting bracket by a quick release thumbscrew. The head mounts
over an alignment pin on the bracket. The angle of the head can be
adjusted over almost 180 degrees, and should be set so that the film enters
and leaves the head at about the same angle. A setscrew on the side of
the bracket can secure the angle of the head should you need to remove
the head. Removing the head may be accomplished by merely loosening
the thumbscrew and disconnecting the cable. Figure 8-5 shows the proper
installation of the reader head assembly onto the telecine feed roller collar.
Figure 8-2 shows a side view of the reader head and bracket, and the film
path.
When mounting the head on your telecine, the following procedure should
be used to ensure that the head does not interfere with the film path.
1. Using the hex key tool provided, loosen the binding screw (10)
Hold the bracket with the alignment post facing towards you,
and the nylon adjusting screws towards the telecine deck plate.
2. Cintel Telecines: Slide the large hole of the mounting bracket
over the last roller before the gate (6) and onto the shaft that
supports the roller. Tighten the binding screw finger tight to
hold the bracket in place.
Philips Telecines: Remove the last roller before the gate, from
its mounting shaft. Slide the large hole of the mounting bracket
over the shaft that supports the roller. Insert the adapter rings
that were supplied with the mounting bracket between the roller
shaft and the mounting bracket.
finger tight to hold the bracket and adapter rings in place. Re-
install the roller onto the shaft.
3. Slip the reader head over the alignment pin on the mounting
bracket and tighten the thumbscrew (11) to hold the head in
place. The head should be positioned such that the film enters
and leaves the reader head rollers at approximately the same
angle.
4. Thread some film into the telecine as you would normally,
making sure that it passes over the reader's rollers. Set the
height of the mounting bracket so that the film is running
smoothly through the reader head rollers. Rotate the bracket
