Gigabit Ethernet Ports
The cPCI-6841 has two 10/100/1000Mbps Ethernet (GbE) ports.
Every port is assigned a unique static MAC Address. Two onboard
Intel® 82541GI Gigabit Ethernet controllers provide two Ethernet
ports and are implemented on a 32-bit/33 MHz PCI bus. The
82541GI supports IEEE 802.3x compliant flow control and IEEE
802.3ab compliant 10/100/1000 Mbps auto-negotiation. Two RJ-
45 connectors for these two LAN ports are located on the front
panel for system management or service requirements.
Universal Serial Bus (USB)
The cPCI-6841 provides one USB 2.0 port on the front panel for
use as an interface to versatile peripherals such as keyboard,
mouse, printer, USB flash disk, etc.
Serial I/O
One serial port is supported by the Winbond W83627HF Super I/O
on the cPCI-6841 and is accessed via a DB-9 connector on the
front panel. This port will be configured as Data Terminal Equip-
ment (DTE). BIOS will initialize the serial port as COM1 with ISA I/
O base addresses of 3F8h and with a default setting of COM1
assigned to IRQ4.
Keyboard/Mouse Controller
The cPCI-6841 uses the Winbond W83627HF Super I/O to imple-
ment the keyboard/mouse controller. The controller is fully 8042
compatible. The cPCI-6841 provides a proprietary combo PS2
connector on the front panel (a cable is included).
FDD Interface
The cPCI-6841 uses the Winbond W83627HF Super I/O to imple-
ment the Floppy interface. Signals are available at the FDD con-
nector.
