Cinema Inputs (Smpte 292 / Hd-Sdi); Fitting A Ferrite-Core Clamp - NEC iS15-2K User Manual

2. Installation

Cinema Inputs (SMPTE 292 / HD-SDI)

For cinema use, this will be the main input port for the projector. The two inputs can
be configured as follows:
• one dual SMPTE 292 port
• two separate, individually selectable single SMPTE 292 ports.
The following source formats will be recognised and decoded by the projector
electronics:
• SMPTE 274M
• SMPTE RP211
• SMPTE 295M
• SMPTE 260M
• SMPTE 296M
HDSDI is a 1.4Gb link, therefore the following or similar cable specification should
be used to ensure fault free communication between source and projector.
• Belden 8281 or equivalent with 75ohm BNC

SDI B

Fitting a ferrite-core clamp

Fit a ferrite-core clamp to each SDI cable used.
• Prise open the catches to open the clamp.
• Position the clamp close to the projector end of the SDI cable, and close it firmly
around the cable, so that the catches snap shut.
• Fasten a cable tie close to the clamp, to ensure that the clamp stays in place.

Notes
For more information about
input connectors see
Connections, in section 6.

For more information about
supported input formats see
Specification, in section 6.
Appendix.
A ferrite-core clamp must be
fitted to each SDI cable used,
to ensure protection from
radio frequency interference.
