Embedded functionality

Storage and Expansion: Supports remote boot from the front panel, up to 8GB bootable CompactFlash (optional), PMC site with PCI-X functionality (with VITA 35 P2 I/O, factory installed on V7768 and V7769 motherboards), etc.

Compatibility and Storage: Complies with VITA 1-1994 standard and supports byte swapping, 32KB NVRAM, optional watchdog timer with reset function, PMC expansion site.

Applicable scenarios: Suitable for various application scenarios such as telecommunications, simulation, instrumentation, industrial control, process control and monitoring, factory automation, automatic testing systems, data acquisition systems, etc.

Installation and setup

Unboxing and hardware setup

After opening the box, it is necessary to check whether the items have been damaged during transportation and pay attention to electrostatic protection.

Hardware settings involve various connectors, joints, and switches, such as VME interface connector (P1), USB 2.0 and other related connectors (P2), CompactFlash slot (P7), etc. Users can configure some jumper wires according to their needs, and factory configured jumper wires should not be modified by users. Modifying jumper wires that are not user configured will void the warranty and may damage the equipment.

Installation steps

If using PMC module, connect it to V7768/V7769 before installing the motherboard, and refer to the product manual of PMC module for configuration and settings.

Insert V7768/V7769 into the system controller or peripheral slot of the VME chassis, ensuring proper alignment and secure installation.

The required peripherals can be accessed from the front panel or rear I/O, and each connector is clearly labeled. The detailed pin distribution can be found in Appendix A.

If the system is not pre configured, a keyboard and mouse need to be connected.

V7768 has an optional onboard CompactFlash disk, please refer to Chapter 3 "Embedded PC/RTOS Functions" for configuration details.

If an external driver module is installed, the BIOS setup program must be used to configure the driver type. Refer to Appendix B for proper system configuration.

If there is a driver module, install the operating system according to the manufacturer's instructions.

BIOS settings

Entering the BIOS setup interface: Pressing the DEL key will enter the BIOS setup utility during system startup, which includes multiple menu options for detailed system configuration.

Main Menu: displays system information such as BIOS version, processor type, clock speed, and supports setting system clock and calendar. The configurable options in the menu are displayed in blue, while the options displayed in gray are not configurable. After selecting an item, its brief description will be displayed on the right side.

Advanced BIOS Setup Menu: Used to configure CPU settings, IDE bus, other external devices, and internal drives. Caution should be exercised during operation, as incorrect settings may lead to system malfunctions. If there is a problem after the change, you can select "Load Failed Safe Defaults" from the Exit menu and restart the system; If a system malfunction prevents access to the BIOS interface, you can refer to the "Installation and Setup" chapter to clear the CMOS.

PCI/PnP Setup Menu: Used to control internal peripheral cards and various interrupts, as well as set the system's plug and play functionality. Similarly, incorrect settings may cause system failures, and the solution is similar to the advanced BIOS settings menu.

Boot Setup Menu: You can set the priority of starting the device, including starting from a remote network. If the installed driver is not displayed in the menu, check the hardware installation. In addition, basic system related behaviors can be set, such as PS/2 mouse support and whether to use "Quick Boot".

Security Setup Menu: Provides password settings for both Supervisor and User. If two passwords are used simultaneously, the administrator password must be set first. The system can be configured to require the user to enter a password every time it starts or enters ezPORT settings. When you forget your password, you need to clear the NVRAM and reconfigure it. Please refer to the "Installation and Setup" chapter for specific instructions.

Chipset Setup Menu: Used to select various options for the chipset in the system, such as CPU configuration and north-south bridge configuration. Due to the fact that chipset settings are processor related, extra caution should be taken when changing settings, following troubleshooting methods similar to those in the above menu.

Exit Menu: You can choose to save or discard changes and exit BIOS settings. If the previous BIOS settings cause system failure, you can select 'Load Failed Safe Defaults' from this menu and continue restarting.

First Boot Menu: Pressing the F11 key will enter this menu during startup, allowing users to choose to boot from a specific device at once, such as selecting ATAPI CD-ROM Drive when installing the operating system from a CD. This selection is only valid for the current boot. If you are unable to access this menu, you can disable QuickBoot Mode in the Main BIOS settings screen, save the changes, and try again.
