* Lens extension is the distance from the outer end of the lens to the front of the projector. It is measured when the lens is
focussed at infinity and fully extended. At other focus settings, the extension could be up to 10mm less.
It is important for calculating throw distance accurately (see  Useful lens calculations, in Section 2. Installation ).

Connections
Cinema Input (SMPTE 292 / HD-SDI) connection
Signal
Ground
SMPTE 292 / HD-SDI signals are very high speed digital signals which req\
uire
better quality coaxial cable than conventional analogue video. The data rate is 1.5
Gigabits per second.
In choosing cable length and connectors for any installation the frequency response
loss in decibels should be proportional to 1 √f, from 1MHz, to 1.5GHz. The following
or similar cable specification should be used to ensure fault free commu\
nication
between source and projector.
•  Belden 8281 or equivalent with 75ohm BNC

Cable complexity and
interference can be reduced by
using the Digilink high

* Hot plug detect (HPD) is fully DVI compliant.  DVI sources detect the \
presence of a display device by providing +5V on pin 14 and looking for +5V on pin 1\
6.
Whenever the projector is operational, and 5V is present on pin 14, pin \
16 will be
held at +5V.
EDID is available even when the projector is switched off.
Operational means that the projector is powered up.  Non operational sta\
tes are powered down and some self test and reprogramming modes.

uncrossed cable should be
used to connect to an external
hub, network or computer.

The projector is a DTE, so use:
• a straight cable to connect to a modem, or
• a null-modem cable as shown here to connect to another DTE
such as a computer.
