6-7-5. External control connector (GPI/O) (D-Sub 37 pin)
It is possible to control the projector with an external device and to control the external device from the projector using an
external control connector (GPIO: General Purpose I/O Ports). Each pin is electrically separated from the projector internal
circuits by a photo-coupler. 8 port input and 8 port output are available.
Please contact your dealer/distributor regarding how to use and to operate them.

6-7-6. SDI-A, SDI-B (HD-SDI input connector) (BNC)
This is a signal input connector (SMPTE 292/HDSDI) for CINEMA.
The SMPTE 292/HD-SDI transfers HDTV signals with 1.5 GHz digital serial \
signals, so use a 75 Ω coaxial cable having a
thickness and characteristics higher than 5C-FB, and use a BNC for the c\
onnector.
