Unpacking Procedures Any precautions found in the shipping container should be observed. All items should be carefully unpacked and thoroughly inspected for damage that might have occurred during shipment. The board(s) should be checked for broken components, damaged printed circuit board(s), heat damage and other visible contamination. All claims arising from shipping damage should be filed with the carrier and a complete report sent to GE Fanuc Embedded Systems Customer Care along with a request for advice concerning the disposition of the damaged item(s).

The VMIVME-7807/VME-7807RC are Pentium M processor-based single board computers 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.


Integrated Peripherals

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.https://www.axcontroler.com/

Ethernet Controller 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.https://www.axcontroler.com/


Digital Visual Interface (DVI) The VMIVME-7807/VME-7807RC have a Digital Visual Interface that provides a high-speed digital connection for visual data types that are display technology independent. DVI is a display interface developed in response to the proliferation of digital flat-panel displays.

For the most part, these displays are currently connected to an analog Video Graphics Array (VGA) interface and, thus, require a double conversion. The digital signal from the computer must be converted to an analog signal for the analog VGA interface, then converted back to a digital signal for processing by the flat-panel display.

This inherently inefficient process takes a toll on performance and video quality and adds cost. In contrast, when a flat-panel display is connected to a digital interface, no digital-to-analog conversion is required. DVI uses Silicon Image's PanelLink, a high-speed serial interface that uses Transition Minimized Differential Signaling (TMDS) to send data to the monitor.

The DFP and VESA Plug and Display interfaces also use PanelLink.

For this reason, DVI can work with these previous interfaces by using adapter cables (depending on the signal quality of the adapter.) DVI also supports the VESA Display Data Channel (DDC) and the Extended Display Identification Data (EDID) specifications. DDC is a standard communications channel between the display adapter and monitor. EDID is a standard data format containing monitor information such as vendor information, monitor timing, maximum image size, and color characteristics. EDID information is stored in the display and is communicated over the DDC. EDID and DDC enable the system, display and graphics adapter to communicate so that the system can be configured to support specific features available in the display. DVI Connectors The DVI connector has 24 pins that can accommodate up to two TMDS links and the VESA DDC and EDID services.


The DVI specification defines two types of connectors (see Figure 1):

•DVI-Digital (DVI-D) supports digital displays only (used on the VMIVME-7807/VME-7807RC)

•DVI-Integrated (DVI-I) supports digital displays and is backward compatible with analog displays (not supported) The VMIVME-7807/VME-7807RC use the DVI-I connector with a single TMDS link.

The DVI-I interface accommodates a 12- or 24-pin DVI plug connector or a new type of analog plug connector that uses four additional pins, plus a ground plane plug to maintain a constant impedance for the analog RGB signals.


GE Fanuc Embedded Systems’

VMIVME-7807/VME-7807RC feature additional capabilities beyond those of a typical desktop computer system. The units provide four software-controlled, general-purpose timers along with a programmable Watchdog Timer for synchronizing and controlling multiple events in embedded applications. The VMIVME-7807/VME-7807RC also provide a bootable CompactFlash Disk system and 32KB of non-volatile RAM. Also, the VMIVME-7807/ VME-7807RC 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.
