Model HD9155 Production Afterburner Manual
2.6.1. Connecting the Video LTC Reader
Connect the LTC output from your video recorder to the HD9155'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 may used to jam
sync the HD9155's Video LTC generator to the code previously recorded on tape.
2.6.2. Connecting the Video LTC Generator
The generator Video LTC output is available on the 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 RTP1) located on the 9000TCIO circuit card.
The generator code output should be connected to the time code input of your standard definition 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.
When the Factory configuration is in use, the LTC Generator output will be jam synced to the incoming
RP188 ANC timecode. The LTC output will be delayed from the incoming timecode by the same delay as
the video. In addition, when the incoming timecode is counting 24 frames per second, the time code
output will be converted to 30 frames per second and will be synchronous with the 2:3 cadence of the
output video. The 00 frames of each second of the incoming timecode will be aligned to the 00 frames of
the output timecode unless the 2:3 cadence is altered by system parameter 10. See Chapter 5 for more
information about System parameters and how they affect the operation of the HD9155.

CONNECTING THE HD9155 TO A COMPUTER
The 9150 Configware™ configuration software is used to customise the configuration the HD9155's
hardware for different applications. Configuration sets can be saved and recalled to speed setups of the
hardware. These configuration sets are loaded into the 'User Configuration' of the HD9155 that is loaded
by operating the front panel Configuration switch.
2.7.1. Physical Connections
A nine pin sub-miniature 'D' connector SERIAL CONTROL is provided for connection to a computer
running the software. This serial port provides a bi-directional RS-232-C data link at 57,600 baud. In
order to connect your HD9155 to your computer make a cable as shown in Figure 2-8. Use this cable to
connect the computer's COM port to the SERIAL CONTROL connector on the rear of the HD9155. The
HD9155 serial port does not have connections for the DTR, DSR, DCD and RI handshake lines. A
standard 9 pin 'straight through' cable may work with some computers if the handshake lines are internally
pulled to the active state. See Chapter 4 for more information on installing the 9150 Configware™
software and configuring the HD9155.
