1.3.14 Video (Only available on cPCI-6820)
The display interface is featured by Asiliant Technologies (former called Chips
and Technologies) 69000 PCI graphics accelerator. The 2MB SDRAM is
integrated in the 69000 as a display memory and internally operates at 83MHz.
The 69000 integrates 8-bit 135MHz RAMDAC and can support up to
640x480x24bpp, 800x600x24bpp, 1024x768x16bpp, and 1280x1024x8bpp
display modes. The CRT interconnections are available on the both front
panel of cPCI-6820 and rear I/O board.
1.3.15 IDE Interface
The fast IDE interface on cPCI-6810/6820 supports up to four IDE devices
including hard disk drives and CD ROMs. Each IDE device can have
independent timing. The IDE interface supports PIO IDE transfers of up to 14
Mbytes/sec and the Bus Master IDE up to 100 Mbytes/sec. The CSB5’s IDE
system contains two independent IDE signal channels. They be electrically
isolated and are configured to the standard primary and secondary channels.
1.3.16 Universal Serial Bus (USB)
The root hub integrated in the CSB5 supports 4 USB serial ports. Two ports
are available on the front panel, with the other 2 ports routed to the rear I/O
board through J5. Additional ports can be added through the use of an
external USB hub. USB allows for the easy addition of peripherals such as
mouse, keyboard, speakers, etc. Transfer up to 24Mb/s is supported. The
cPCI-6810/6820 provides the standard 0.5A at 5V to the peripherals. The
power to each port is protected by a single polyswitch (this current rating
allows for inrush currents).
1.3.17 Serial I/O
Two serial ports are supported on the cPCI-6810/6820. The EIA232 drivers
and receivers reside on board. COM1 is implemented as an RJ45 connector
on the front panel. Both COM1 and COM2 are available on rear I/O board. The
BIOS will initialize the serial ports as COM1 and COM2 with default ISA I/O
base addresses 3F8h and 2F8h respectively. This default configuration also
assigns COM1 to IRQ4 and COM2 to IRQ3. The supported baud rate are
1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps.
