audio signal into the audio controller. The audio cable of your CD-ROM
drive will be used to connect to CN24.
2.15 COM port connector (CN19)
The PCM-9584 provides four RS-232 serial ports (COM1,3,4:RS-232,
COM2: RS-232/422/485) in one COM port connector. The COM port
connector is a 40-pin, DF13A-40DP-1.25V (Hirose Electric Co., Ltd.). It
provides connections for serial devices (a mouse, etc.) or a communica-
tion network. You can find the pin assignments for the COM port connec-
tor in Appendix C. COM2 can be configured to operate in RS-232,RS-
422, or RS-485 mode. This is done via JP2.
2.16 VGA/LVDS interface connections (CN26, CN22)
The PCM-9584’s AGP SVGA interface can drive conventional CRT dis-
plays and is capable of driving a wide range of LVDS flat panel displays.
The board has three connectors to support these displays: one for stan-
dard CRT VGA monitors, one for LVDS type LCD panels and one for
DVI type LCD panels.
2.16.1 CRT display connector (CN26)
CN26 is a 16-pin, dual-inline header used for conventional CRT dis-
plays. A simple one-to-one adapter can be used to match CN26 to a stan-
dard 15-pin D-SUB connector commonly used for VGA. Users can drive
a standard progressive scan analog monitor with pixel resolution up to
1600 x 1200 at 85 Hz and up to 2048 x 1536 at 75 Hz. Pin assignments
for CRT display connector CN26 are detailed in Appendix C.
2.16.2 LVDS LCD panel connector (CN22)
The PCM-9584 uses the Intel 915 GME chipset that supports single- or
dual-channel LVDS panel up to UXGA panel resolution with frequency
range from 15MHz to 112MHz.
The PCM-9584 supports single or dual-channel LVDS panels up to
UXGA panel resolution with frequency range from 25MHz to 112MHz.
The display mode can be 2 channel (2 x 18bit) LVDS LCD panel dis-
plays, or optional (2 x 24bit) LVDS LCD panel display. Users can con-
nect to either an 18, 24, 36 or 48bit LVDS LCD with CN22.
