GE VMIACC-5595 Reflective Memory Hub Assembly

GE VMIACC-5595 Reflective Memory  Hub Assembly

Product Overview

The VMIACC-5595 automatically bypasses ports when the absence of valid synchronization patterns is detected. Three LEDs, adjacent to each port, provide a visual indication of the port status. Additional status indications and modes of operation are available through either the serial port or the Ethernet port.

Status information includes the detection of installed transceivers, the detection of signal (light), the detection of valid synchronization patterns and the port operation speed (2Gb/s). Control registers allow the channel bypass to be based on the absence of a single valid synchronization pattern or multiple synchronization patterns. A bypass can also be based simply on the loss of a signal (light). In addition, each port can be manually forced either active or bypassed regardless of the status indicators.

Features:

• For use with GE Fanuc Embedded Systems’ VMIxxx-5565 Reflective Memory network of products 

• Provides up to eight ports using small form factor pluggable (SFP) transceivers 

• Hub assemblies can be cascaded with a maximum of 256 nodes

• Automatically bypasses defective or disconnected nodes in a fiber-optic network 

• Automatic bypass can be optionally controlled by the loss of signal or by the loss of sync pattern 

• Each port regenerates the serial optical signal, eliminating link losses and reducing jitter 

• Configurable for use with cables up to 10km in length 

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

• RS232 port for local access and control 

• Optional 19-inch 1U rack mount or desktop enclosure 

• Internal universal power supply 

• Dark on Dark option turns off the board’s transmitter if the receiver does not detect a signal (available for firmware versions 02.00 and later)

Physical/Environmental Specifications

Desktop Assembly Dimensions: 16.73 inches wide by 10.0 inches deep by (1U) 1.72 inches high. Dimensions do not include nonskid self-adhesive feet.

Rack Mount Assembly Dimensions: The basic dimensions are the same as the desktop assembly, but include two 1U rack mount brackets for the standard 19-inch rack.

Front Panel Connectors: There are eight industry-standard SFP transceivers. The SFP receptacles not populated with transceivers contain EMI dust plugs. There is one RJ45 Ethernet connector and one 9-pin female D-subminiature RS232 connector.

Cabling: Each installed SPF transceiver requires either one Duplex LC-type fiber-optic cable or two Simplex LC-type fiber-optic cables. The Simplex cables are best suited for cascading hubs. The Duplex cables can be used for all other interconnectivity.

Rear Panel Connectors: The rear panel contains a power entry module that includes a power ON/OFF switch, a 4A/250V fuse, and a globally accepted IEC receptacle.

Power Requirements: 90 to 264VAC, 47 to 440Hz, 25W. 

Power supply and power entry module meet safety standards: UL, C-UL: UL 1950 TUV: EN69050

Temperature

Operating: 0° to +65° C 

Storage: -40° to +85° C
