• Using GPIO Control
Y
ou can use GPIO control for the projectors health check and error check. Also, you can use the output as the trigger to contr ol
external devices.
The following functions are assigned to the pin number 13-32, 14-33, 15-34, and 16-35 (EXT_GPOUT1\
 - EXT_GPOUT4) as the
default. You can change the assigned functions.

GPIO control status check 
ON: GPIO control (input) is unavailable. 
OFF: GPIO control (input) is available. 
Error check
ON: Error
OFF: No error
Media block status check
ON: The content is being played
OFF: The content is stopped/paused
Health check (heart beat)
ON and OFF are alternately output when operations are 
normal.

6. Appendix
6-6-4. SDI-A, SDI-B, SDI-C, SDI-D (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   coaxial cable having a
thickness and characteristics higher than 5C-FB, and use a BNC for the c\
onnector.
Signal GND
6-6-5. DVI-A, DVI-B (DVI digital Input connector) (DVI-D 24 pin)
This is a single link DVI input connector that is compliant with hot plu\
g detect (HPD). Use a single link cable. Noise may be
generated in the video if you use a dual link cable.
EDID is available even when the projector is switched off.
