7.2 TCO-HDSP
After installation of the TCO-HDSP update to the latest driver and firmware version, found on
the website www.rme-audio.com
in the section Download.
After a reboot the Settings dialog includes an additional page labelled TCO, and on the main
page the new sync-option TCO can be selected.
For synchronization to a video or LTC signal choose Clock Mode AutoSync and TCO as Pre-
ferred Sync Ref on the main page of the settings dialog.
All further settings are then done on the TCO page.
LTC In: The time values read from the LTC signal. These values are passed on to the applica-
tion unchanged.
Input State: An LTC input signal detected as valid (valid) is followed by the display of the num-
ber of frames per second, and whether this is Full Frame or Drop Frame code. 23.976 is de-
tected as 24, 29.97 as 30. A valid video signal is shown as PAL or NTSC. An incoming word
clock signal is analyzed and displayed to be in the Single Speed, Double Speed or Quad Speed
range.
Sync Source: Input select switch for the
inputs LTC, video and word clock. Lock is
displayed as soon as the TCO is able to
synchronize on an input signal. Also at
the bracket the green LED will light up
then.
Video / Word Input: The BNC input can
be terminated with 75 Ohms. At the
bracket the yellow LED will light up with
termination activated.
WCK Conversion: Default setting is 1:1.
This very special option allows for a
synchronous conversion of the word clock
input signal. 44.1 kHz will turn into 48
kHz, where the 48 kHz are not free
running, but have a synchronous
relationship to the original clock. The
same is available for converting 48 kHz to
44.1 kHz.
Frame Rate: The frame rate of the
incoming SMPTE signal must always be
defined manually, as it is not detected
automatically from the input signal.
