The head offset learning procedure calculates the exact offset between the head and the gate, and is
normally required only during installation.
TRACKER™ manual section titled Learning the KeyKode Head Offsets and is also provided in the
online help for KeyLog TRACKER™.
1. 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 KK indicator on the KeyLog TRACKER™ status bar should
blink each time a barcode data record is sent to the 9025TR.
2. The next step is to learn the KeyKode head offsets.
TRACKER™ Telecine Setups screen. Select Telecine Setups... from the Edit menu. The
Telecine Setups window will open and the System Default Telecine Setup will be selected.
Press the Edit button to make changes to this telecine setup, and press the Head Offsets
button to open the Head Offsets screen. This screen shows a summary of the possible
head offsets available for the video standard you are using.
3. Select the head offset that you want to learn and press Learn button. The head offset
learning wizard will guide you through each of the steps necessary to properly learn the
head offset. The first screen reminds you to perform the Biphase accuracy test before you
attempt to learn the head offset. If you have already done that press the Next button to
proceed. If not, then go back and perform the biphase accuracy test as described in section
3.1.
4. On a piece of bar-coded film stock, select a reference frame that is beside one of the
barcodes. (The reference frame is located beside the reference dot of the barcode as
shown in the graphic on the Head offset wizard screen.) Identify this frame with a punch
mark or grease pencil. On 35 mm film, make sure that you don't choose one of the mid-foot
bar codes but one of the whole foot ones which have a larger human readable font. The
second screen shows what the reference frame KeyKode number should look like for the
film type you are using. Press the Next button to proceed.
