•
Do not run the timecode cable along power lines, over florescent light fixtures, or near motor
controllers. Cable must be shielded.
•
If the timecode reader-head circuit board is D424 Rev. F or
earlier
, replace the reader or do a
“repair-exchange” on the reader.

DDE or DTS equipment problem
•
Verify the lateral adjustment is correct on the reader. Consult DDE technical support for
guidance on the alignment procedure.
•
Readers with D424 circuit boards only: Verify the voltage to the reader’s red LED is properly
calibrated by following the procedure in technical notice TN-E550. Reader heads with the
D424 circuit board have a date code of May 2006 or earlier. Reader heads with the newer F430
circuit board are self calibrating and require no adjustments. The P.C. board number can be
viewed, without removing the cover, by tilting the reader and looking just below the 9-pin
connector (see examples below).

•
Check the timecode cable. Verify continuity and physical integrity. If running two projectors
to one player, be sure you have used the correct timecode cables and that they are correctly
wired.
•
Check firmware inside the DTS-6 or -6D player (not DTS-6AD cinema processor). The current
TCR version is V1.46 and is located at U14 on the D422 board.
•
Borrow a known good reader from another screen. If this fixes the problem, replace the faulty
reader.
