2.6.1. Connecting the Video LTC Generator
The Video LTC Generator output is available on the Video Timecode Out XLR connector on the rear
panel. The output level of the generator is factory set to 1 volt peak to peak, but may be adjusted using
the level adjustment located on the 9000TCIO circuit card.
The generator code output should be connected to the time code input of your video recorder. Pin 1 of the
XLR is ground, and pins 2 and 3 provide a balanced output. When using a machine with an unbalanced
input the signal should be connected to Pin 3 of the generator output XLR. Pin 2 should be left open.
The 9025TR records database index tags in the user bits of Video LTC. If the VTR
is being slaved to the 9025TR's Video LTC output, the time code generator built
into the VTR should be set to the "EXTERNAL PRESET" mode of operation. The
VTR's time code generator does not understand the counting sequences of the
encoded data, and will introduce delays and possibly errors in the user bit data if it
attempts to regenerate the timecode before recording it on tape.
2.6.2. Connecting the Video LTC Reader
Connect the LTC output from your video recorder to the 9025TR's Video LTC In XLR connector. When
using an unbalanced input to the reader, the signal should be applied to pin 3 of the reader input
connector. Normally, the unused input, (pin 2) should be connected to ground (pin 1). This input is used
to jam sync the 9025TR's Video LTC generator to the code previously recorded on tape. This mode is
used when the Record VTR is generating its own time code and the 9025TR needs to read it to insert the
VTR's timecode into the RP215 VANC packets (in HD mode) or the RP201 Three line VITC (in SD mode).
2.7.
CONNECTING THE AUDIO PLAYER TIME CODE
The frame rate of the Audio timecodes may be different than the system video frame rate. Specifically, in
applications where the video rate is 23.98 frames per second the Audio frame rate will usually be 29.97
frames per second. The Codes and Outputs tabs of the configuration screens in the KeyLog TRACKER™
software control the use of the Audio LTC reader and generator.
2.7.1. Connecting the Audio LTC Generator
The Audio LTC output Generator is available on the Audio Timecode Out XLR connector at the rear panel.
This time code output is driven from the telecine biphase and may also be updated from incoming film
timecode being read by the 5550 Decoder. Normally the Audio LTC output is only required when using
Film time code, or you wish to manually enter time code slate numbers and have the audio player follow
the telecine movement. In applications where the audio player is being controlled by a telecine edit
controller device, you do not need to connect the 9025TR Audio LTC output. The output level of the
generator is factory set to 1 volt peak to peak, but may be adjusted using the level adjustment located on
the 9000TCIO circuit card.
The generator code output should be connected to the chase synchroniser time code input of your audio
player. Pin 1 of the XLR is ground, and pins 2 and 3 provide a balanced output. When using a machine
with an unbalanced input the signal should be connected to Pin 3 of the generator output XLR. Pin 2
should be left open.
