2 Installation
2.1 Installation in the Densité frame
The IRD-3811 and its associated rear connector rear panel must be mounted in a Densité
3
frame. It is not necessary
to switch off the frame’s power when installing or removing the card. See the Densité
3
Frame manual for detailed
instructions for installing cards and their associated rear panels.
2.2 Rear Panels
The IRD-3811 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 IRD-3811 must be installed in the
right-most of the two slots
covered
by the panel in order to mate with the panel’s connectors.
NOTE: attempting to install the card in the wrong slot could result in damage to the edge connector of the
rear panel. BE CAREFUL

2.3 Connections
The rear panel connections are as follows:
•
REF IN –
External reference input
For external synchronization, connect a black studio reference signal to the BNC labeled
REF IN
.
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.
The table shows the reference signals appropriate for the
supported input formats. In essence, the input and the
reference must have the same frame rate.
A reference mismatch will 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.
