2 Installation
2.1 Installation in the Densité frame
The HCO-1822 and its associated rear connector rear panel must be mounted in a DENSITÉ frame. It is not
necessary to switch off the frame’s power when installing or removing the card. See the DENSITÉ Frame manual for
detailed instructions for installing cards and their associated rear panels.
2.2 Rear Panel Connector
The HCO-1822 has multiple inputs and outputs, and making space for all the necessary connectors at the rear of the
frame requires a double-width rear panel.
With the double-width rear panel installed, the HCO-1822 must be installed in the right-most of the two slots covered
by the panel in order to mate with the panel’s connectors.
If it is placed in the wrong slot, the front panel LED will flash red. Move the card to other slot for correct operation. No
damage will result to the card should this occur.
The rear panel connections are as follows:
REF IN – Studio reference input
For external synchronization, connect a black studio reference signal to the BNC labeled
REF IN
.
NB: The loop must
be terminated if not used.
The reference input must conform to SMPTE 170M/SMPTE
318M/ITU 624-4/BUT 470-6 for standard definition signals
and SMPTE 274M / SMPTE 296M for high definition signals
and is used to phase the HD/SD SDI outputs to the studio.
A reference mismatch may occur if there is a difference
between the input video format’s frame rate and the
reference format’s frame rate. When a mismatch occurs, an
input error will be flagged and the card-edge Status LED
will turn red to indicate the mismatch. The table shows the
supported reference signals with respect to the input
signals:
HD/SD IN – serial digital HD/SD input
Connect up to two serial digital video signal, conforming to the SMPTE 292M standard for HD input signals and
SMPTE 259M standard for SD input signals, to the BNC labeled
HD/SD SDI IN
. DVB-ASI per EN 50083-9 is also
supported. The HCO-1822 will automatically switch to the detected line format.
