The network capability is provided by the Intel 82571 Dual Ethernet Controller forGigabit Ethernet. This Ethernet controller is PCI-E bus based and is software
configurable. The V7768/V7769 support 10Base-T, 100Base-TX and 1000Base-T
Ethernet.
10Base-T A network based on the 10Base-T standard uses unshielded twisted-pair cables,
providing an economical solution to networking by allowing the use of existing
telephone wiring and connectors. The RJ45 connector is used with the 10Base-T
standard. 10Base-T has a maximum length of 100 meters.
100Base-TX The V7768/V7769 also support the 100Base-TX Ethernet. A network based on a
100Base-TX standard uses unshielded twisted-pair cables. 100Base-TX has a
maximum length of 100 meters.
1000Base-T The V7768/V7769 support 1000Base-T Ethernet using the Intel 82571 dual
Ethernet controller. The interface uses shielded cables with four pairs of
conductors, along with an RJ45 connector on the front panel.
NOTE
Ethernet activity is noted on the front panel LEDs by a blinking
yellow LED. The yellow LED will be on continuously when the
Ethernet port is linked but with no activity
The SVGA port on the V7768/V7769 is controlled by the Intel 945GM Graphic and
Memory Controller Hub (GMCH). The GMCH is hardware and BIOS compatible
with the industry SVGA and digital video standards supporting both VESA high resolution and extended video modes.
Table 2-6 shows the graphics video modes
supported by the GMCH video controller for analog monitors.
Not all SVGA monitors support resolutions and refresh rates beyond 640 x 480 at
85 Hz. Do not attempt to drive a monitor to a resolution or refresh rate beyond its
capability.

GE’s V7768/V7769 feature additional capabilities beyond those of a typical
desktop computer system. The units provide four software-controlled, generalpurpose timers along
with a programmable Watchdog Timer for synchronizing
and controlling multiple events in embedded applications. The V7768 provides a
bootable CompactFlash Disk system and 32 KByte of non-volatile RAM. Also, the
V7768/V7769 support an embedded intelligent VME bridge to allow compatibility
with the most demanding VME applications. These features make the unit ideal
for embedded applications, particularly where standard hard drives and floppy
disk drives cannot be used.
3.1 VME Bridge
3.1.1 Features
• Complete six-line Address Modifier (AM-Code) programmability
• VME data interface with separate hardware byte/word swapping for master
and slave accesses
• Support for VME64 multiplexed MBLT 64-bit VME block transfers
• User-configured interrupter
• User-configured interrupt handler
• System Controller mode with programmable VME arbiter
(PRI, SGL and RRS modes are supported)
• VME BERR bus error timer (software programmable)
• Slave access from the VME to local RAM and mailbox registers
• Full-featured programmable VME requester
(ROR, RWD and BCAP modes are supported)
• System Controller auto detection
• Complete VME master access through five separate Protected-mode
memory windows
The V7768/V7769 support High Throughput DMA transfers of bytes, words and
longwords in both Master and Slave configurations.
If Endian conversion is not needed, GE offers a special “Bypass” mode that can be
used to further enhance throughput (not available for byte transfers).
The V7768/V7769 VME interface is provided by the PCI-to-VME bridge built
around the Tundra Semiconductor Corporation Universe IID VME interface chip.
The Universe IID provides a reliable high-performance 64-bit VME-to-PCI
interface in one design. The functions and programming of the Universe-based
VME interface are addressed in detail in a companion manual titled: GE’s Tundra
Universe II Based VME Interface Product Manual
