GE VMIVME-2536 32-Channel Optically Coupled Digital I/O Board with Built-in-Test
The VMIVME-7807/VME-7807RC are Pentium M processor-based single boardcomputers compatible with modern industry standard desktop systems. The
VMIVME-7807/VME-7807RC therefore retain industry standard memory and I/O
maps along with a standard interrupt architecture. The integrated peripherals
described in this section (such as serial ports, USB ports, IDE drives, floppy drives,
video controller and Ethernet controller) are all memory mapped the same as
similarly equipped desktop systems, ensuring compatibility with modern operating
systems.
The following sections describe the standard features of the
VMIVME-7807/VME-7807RC
The VMIVME-7807/VME-7807RC incorporate an SMSC Super I/O (SIO) chip. The
SIO provides the VMIVME-7807/VME-7807RC with two 16550 UART-compatible
serial ports, keyboard and mouse port. The keyboard and mouse ports are available
via the front panel using a standard PS/2 type connector. COM1 is accessed via the
front panel. COM2 is routed to the VME P2 connector.
COM ports 3 and 4 are also provided by the 6300ESB I/O Controller Hub and are
routed to the VME P2 connector.
The parallel IDE interface is provided by the Intel 6300ESB I/O Controller Hub. The
IDE interface supports two channels: primary and secondary. The secondary channel
is routed onboard to the optional CompactFlash socket. The primary channel is routed
out of the VME P2 backplane connector to an RTM which terminates into a standard
40-pin header. This channel can support a master and slave drive. The IDE interface
on the VMIVME-7807/VME-7807RC supports Ultra ATA/33, Ultra ATA/66 and Ultra
ATA/100 drives and automatically determines the proper operating mode based on
the type of drive used. In order to properly function in the Ultra ATA/100 mode, a
special 80 conductor cable must be used instead of the standard 40 conductor cable.
This cable is typically available from the Ultra ATA/100 drive manufacturer.
A Serial ATA Drive Interface is also provided by the 6300ESB I/O Controller Hub. The
Serial ATA port can be used alone or in limited conjunction with the parallel IDE
interface.
NOTE: Selection of drive type (parallel or serial), along with detailed IDE/ATA
selections is available in the CMOS Advanced BIOS Setup Menu.

The network capability is provided by the Intel 82546EB for the VMIVME-7807 or the
Intel 82546GB for the VME-7807RC Ethernet Controller for Gigabit Ethernet and the
Intel 82551 10/100 Mbit Ethernet. These Ethernet controllers are PCI bus based and
are software configurable. The VMIVME-7807/VME-7807RC supports 10BaseT,
100BaseTX and 1000BaseT Ethernet.
10BaseT
A network based on the 10BaseT 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 10BaseT
standard. 10BaseT has a maximum length of 100 meters.
100BaseTX
The VMIVME-7807/VME-7807RC also supports the 100BaseTX Ethernet. A network
based on a 100BaseTX standard uses unshielded twisted-pair cables and a RJ45
connector. 100BaseTX has a maximum length of 100 meters.
1000BaseT
The VMIVME-7807/VME-7807RC support 1000BaseT Ethernet using the Intel
82546EB for the VMIVME-7807 or the Intel 82546GB for the VME-7807RC dual
Ethernet controller. The interface uses shielded cables with four pairs of conductors,
along with an RJ45 connector on the front panel or routed to the VME P2 connector.
The Gigabit Ethernet is also available with the optional VITA 31.1 routed out of the
optional P0 connector.
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.
