Main features

VMIxxx-5565 Reflective Memory Network Product for GE Fanuc Embedded Systems

Use small form factor pluggable (SFP) transceivers, providing up to 8 ports

Hub components can be cascaded and support up to 256 nodes

Automatically bypass defective or disconnected nodes in fiber optic networks

The automatic bypass function can be controlled by signal loss or synchronization mode loss

Regenerate serial optical signals at each port, eliminate link loss and reduce jitter

Can be configured to use cables up to 10km in length

10BaseT Ethernet TCP/IP port for remote access and control

RS232 port is used for local access and control

Optional 19 inch 1U rack installation or desktop enclosure

Built in universal power supply

Dark to Dark "option: If the receiver does not detect a signal, the onboard transmitter can be turned off (applicable to firmware version 02.00 and higher)

Ordering Options

Option Description

B (number of single mode (10km) pluggable transceivers) 0, 1, 2, 3, 4, 5, 6, 7 or 8

C (number of multi-mode pluggable transceivers) 0, 1, 2, 3, 4, 5, 6, 7, or 8

Cable specifications

1. Simplex cable specifications

Fiber optic cable - multimode 62.5 micron core

Fiber optic cable assembly: VMICBL-000-F5, cable length code ABC corresponds to different lengths, such as 000=0.5 feet (0.15m), 001=1 foot (0.31m), etc

2. Duplex cable specifications

Fiber optic cable - multimode; 62.5 micron core

Fiber optic cable assembly: VMICBL-000-F6, cable length code ABC corresponds to different lengths, such as 000=3 feet (1m), 001=6 feet (2m), etc

Functional characteristics

1. Port wavelength and distance

Multimode port wavelength: 830 to 860nm, multimode cable length: maximum 300m

Single mode (10km) port wavelength: 1300 to 1335nm, single mode (10km) cable length: maximum 10km

Single mode (80km) port wavelength: 1540 to 1570nm, single mode (10km) cable length: maximum 80km

2. Core functions

It is a hosted hub designed to be used in conjunction with GE Fanuc's VMIxxx-5565 series reflective memory real-time network products for embedded systems

When signal loss or loss of effective synchronization mode is detected, the port can be automatically bypassed to keep other nodes in the network running

The optical port adopts a small form factor pluggable (SFP) transceiver, which only needs to be configured with the required port. It can be combined with multi-mode (short distance) or single-mode (long distance) transceivers to save small network costs and optimize the system

For large networks, multiple VMIAC-5595 components can be cascaded, supporting up to 256 nodes

The reflective memory network can be monitored and controlled through a simple PC serial port (RS232 port) or through a local area network (LAN) or web browser (Ethernet port)

3. Control and Status

Additional control registers allow manual disabling of transmitters on any port

The front panel manual switch includes a received momentary reset switch and a Gang Select switch. The Gang Select switch configures the VMIACC-5595 port as an 8-port loop or two independent 4-port loops

The three LEDs next to each port provide visual indications of port status, and additional status indications and operating modes can be obtained through serial or Ethernet ports

The status information includes detection of installed transceivers, detection of signals (light), detection of effective synchronization modes, and port operation speed (2Gb/s)

Control registers allow channel bypassing based on the absence of a single valid synchronization mode or multiple synchronization modes, as well as signal (light) loss. Each port can be manually activated or bypassed, regardless of the status indicator

4. Ethernet controller

10BaseT interface conforms to Transmission Control Protocol/Internet Protocol (TCP/IP) standard

Each hub component has a unique MAC address and can run on a local area network (LAN) or a wide area network (WAN)

Contains a remote user interface available via standard Ethernet connection, controlled by a standard HTML based web browser, displaying status data, supporting bypass mode, "dark to dark", and forcing each port on/off or automatic, all of which are saved in NVRAM
