2.5.
CONNECTING THE LINEAR TIME CODE
The HD9010TM-IRIG has one linear time code (LTC) input and two LTC outputs. The frame rate of the
primary LTC output will be the same as the system video frame rate. The frame rate of the AUX LTC
output will be the same as primary LTC output when the system video frame rate is 25 frames per second.
2.5.1. Connecting the Primary LTC Generator
The primary LTC Generator output is available on the LTC 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 (labelled RTP1) located on the 9000TCIO circuit card.
The auxiliary LTC Generator output is available on the AUX LTC 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 (labelled RTP2) 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.
2.5.2. Connecting the LTC Reader
Connect the LTC output from your video recorder to the HD9010TM-IRIG's 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 HD9010TM-IRIG'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 HD9010TM-IRIG needs to
read it to insert the VTR's timecode into the RP188 Ancillary time code packets.
2.6.
CONNECTING THE AUXILLIARY TIME CODE
The frame rate of the auxiliary timecode may be different than the system video frame rate. Specifically, in
applications where the video rate is 23.98 frames per second the auxiliary time code frame rate will usually
be 29.97 frames per second.
2.6.1. Connecting the Auxiliary LTC Generator
The auxiliary LTC output Generator is available on the AUX LTC OUT XLR connector at 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 (labelled RTP2) located on the 9000TCIO circuit card.
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.
