10 | IRD-3802
2.4 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.
• ASI IN – ASI video (2)
Connect up to two DVB-ASI signals conforming to EN 50083-9. The IRD-3802 can automatically switch to
the detected input.
• ASI OUT – Outputs the selected ASI or de-encapsulated IP input
• HD/SD OUT 1 & 2 – SDI output, HD or SD
The IRD-3802 provides two identical HD/SD SDI video outputs on BNC connectors. The SDI video signals
conform to the SMPTE 292M and SMPTE 259M-C standards. The output format follows the input format.
• COMP OUT – down-converted and encoded composite output (requires Analog Output option)
This output is not frame-synchronized, and the video has not been processed through the post-processing
blocks of the IRD-3802.
• Audio OUT (L & R) – analog audio extracted from the input signal (requires Analog Output option)
This audio is also embedded in the output video stream. If the input audio is 5.1, the user must select the
two source channels to monitor; otherwise, a downmix will be monitored.
• ETH – Gigabit Ethernet – can be configured as input or output
