Necessary equipment and connecting
Connect the following equipment as shown in the right figure.
• This projector
• Personal computer (with Microsoft
®
Windows
®
98/Me/XP
operating system)
(For Microsoft
®
Windows
®
98, use SE or later.)
• Monitor for personal computer
• RS-232C cable
• USB cable
• Signal generator (equivalent to VG-812)
• SVGA_WRGB_64scale signal (for C/W delay adjustment)
• XGA_WRGB_64scale signal (for C/W delay adjustment)
Test signal
• SVGA signal (Vertical frequency 60 Hz) (for SD420U / SD430U)
• XGA signal (Vertical frequency 60 Hz)
(for XD420U / XD430U / XD435U / XD435U-G)
• NTSC (480i) signal (Vertical frequency: 59.94 Hz)
The timing and patterns for the adjustment are as follows :
Program ROM : LC12 Ver. 1.8
(for SD420U / SD430U)
Program ROM : LC6 Ver. 1.9
(for XD420U / XD430U / XD435U / XD435U-G)
* Though the signal generator supplies
this signal as a green signal, the
projector receives it as Y/C
B
/C
R
signal.
Therefore, this signal is projected as a
full white SMPTE signal.
