The adapter is supplemented with 4Mbyte external synchronous DRAM cache and high-bandwidth 64-bit data interface.

Supports screen resolutions up to 1600x1200x256 colors(single view mode).

Network controller:

Dual Ethernet controllers,supporting 10BaseT and 100BaseTX.

Supports network connection through two RJ45 connectors.

Supports remote LAN boot.

System bus:

Implements 133MHz system bus through Intel 815E chipset.

Expansion interface:

Provides PMC expansion interface.

Operating system support:

Supports operating systems such as Windows 2000,VxWorks,Solaris,QNX,LynxOS and Linux.

2.Input and output module

The VMIVME-7750 input and output module is a digital control board module with the following features:

Input channel:It has multiple input channels for receiving digital signals or analog signals from sensors and devices.Users can select the appropriate number and type of input channels through configuration and programming.

Output channels:Multiple output channels are available for controlling external devices,such as actuators,relays,etc.Output channels can send control signals to operate and control the device.

Data conversion and processing:Data conversion and processing functions are available,which can convert input signals into digital form and process,filter,amplify,etc.

Communication interface:Data transmission and communication with other system components are usually carried out through standard communication interfaces,such as PCI,VMEbus,etc.

Programmable functions:Programmable functions may be available,allowing users to program and customize according to specific system configurations and application requirements.

Multiple signal type support:Supports multiple signal types,such as digital signals,analog signals,etc.,and can handle different types of input and output signals.

High-speed data transmission:High-speed data transmission function enables fast data acquisition and real-time control.

Reliability and stability:Made of high-quality electronic components and materials,it has high reliability and stability after strict quality control and testing.
