The serial control terminals, COMPUTER1 (M1702) and COMPUTER2 (M1701),
are connected to the EEPROMs for Plug and Play, COMPUTER1 for IC1701,
COMPUTER2 for IC1702, respectively. This enables the reading PC to read
EDID information and detect the projector. (COMPUTER3 is not supported.)
The HDMI terminal (15,16 pin) is connected to the HDMI Receiver IC (IC2203).
This enables the PC to read EDID information and detect the projector.
For the Display Port, when the Display Port Receiver IC (2404) is powered, it
reads EDID data from the external EEPROM (IC2403) and stores it in the
Display Port Receiver IC. Using the AUX Channel of the Display Port terminal
(pins 15, 17), EDID information stored in the Display Port Receiver IC is read.
This enables the PC to detect the projector.
This projector's Plug and Play corresponds to DDC/2B.
In addition, using a dedicated tool for the EDID writing, writing in COMPUTER1:
EEPROM (IC1701), COMPUTER2: EEPROM (IC1702), HDMI: HDMI Receiver
IC (IC2203), Display Port: EEPROM (IC2403) are possible via the route of PC,
CPU, SyncDet (IC2801).
It is only possible via PC. Direct writing from each terminal is not possible.
