3. Slip the top of the 2RU rear panel into the slot
at the bottom of the adapter, and secure it to
the frame using the captive screw at the
bottom of the panel.
2.4 Signal Connections on Rear Connector Panels
Ten rear panels are available for the HDA-19x1. Panels are available for the Densité 2RU frame, and also for the
Densité 3RU frame. The 3RU versions are identified by the number 3 in the size designator portion of the part
number, e.g.
HDA-19x1-SRP is a 2RU version
HDA-19x1-3SRP is a 3RU version
The panel layouts and connectors are illustrated in section 2.5.
The connectors and signal types are the same for all rear types, and are as follows:
HD SDI IN
– serial digital HD/SD input
Connect a serial digital video signal, conforming to the SMPTE 292M standard for HD input signals or SMPTE 259M
standard for SD input signals, to the BNC labeled
HD SDI IN
. DVB-ASI is also supported. The HDA-19x1 will
automatically switch to the detected video line format.
HD SDI OUT
– serial digital video outputs
The HDA-19x1 provides multiple HD/SD SDI video outputs on BNC connectors, labeled
HD SDI OUT 1
,
2
, etc. The
SDI video signal conforms to the SMPTE 292M and SMPTE 259M-C standard. Not all outputs support DVB-ASI
– see
the note on page 13.
Fiber I/O connector
SFP optical modules are small, hot-pluggable cartridges which provide fiber connectivity to the HDA-1911/1931
distribution amplifiers. By using fiber instead of coaxial cable, these interfaces can be used over much longer
distances without impacting signal quality.
