【英文介紹】
The VME-7807RC-414001 may be a Single Board Computer (SBC) designed specifically for VME systems. A single-board computer is a complete computer system that integrates a processor, memory, I/O interface, and other necessary electronic components on a printed circuit board. These computers are designed to be embedded into larger systems, providing control and data processing functions.
Specific specifications and features of VME-7807RC-414001 may include the following (but please note that this information may need to be confirmed according to the actual product manual or specification sheet) :
Processor: A high-performance processor may be integrated to perform complex computation and control tasks.
Memory: Equipped with a certain capacity of memory for storing programs and data.
I/O interfaces: Multiple types of input/output interfaces are provided to connect external devices, sensors, and actuators.
Extensibility: May have expansion slots or connectors that allow additional functional modules to be added.
Firmware/Software support: The operating system or firmware may be pre-installed, allowing users to customize the development according to their needs.
Reliability and durability: Designed for use in industrial environments, it may be resistant to vibration, temperature and humidity changes.
Compatibility: Meets VME bus standards and can be integrated with other VME devices and systems.
Since the VME-7807RC-414001 is not a standard model (at least not until my last knowledge update date), the above information is based on the general characteristics of similar products. In order to obtain accurate technical details and specifications, it is recommended to contact the manufacturer directly or check the relevant product manuals and technical materials.
In addition, single-board computers have a wide range of applications in industrial automation, aerospace, military, and transportation, where they are often used as core components of control systems responsible for functions such as data acquisition, processing, and control output.
The VMIAC-5595-208 is a reflective memory hub assembly designed to operate with the General Electric Fanuc /VMIC 5565 series Reflective Memory real-time networking products. When a signal loss or loss of effective synchronization mode is detected, it can automatically bypass the port, allowing other nodes in the network to remain operational. Since fiber optic ports are enabled with small pluggable (SFP) transceivers, only the required ports need to be installed.
The VMIAC-5595-208 SFP transceiver can be a combination of multi-mode (short range) or single-mode (long range) transceivers, allowing cost savings as well as system optimization in small networks. For larger networks, several VMIAC-5595 components can be cascaded, allowing an array of management hubs of up to 256 nodes. Each port regenerates the serial optical signal, eliminating insertion losses and cable attenuation problems, and signal regeneration also reduces jitter.
In addition, the VMIAC-5595-208 also has an RS232 port, enabling you to monitor and control reflected memory networks from a simple PC serial port. The bypass can also be simply based on the loss of signal (light). Additional control registers allow transfers to be manually disabled on any port.
