GE VMIACC-5595-208 350-805595-208L

Description

Introduction
The VMIACC-5595 is a managed hub designed to operate with
the GE Fanuc Embedded Systems’ VMIxxx-5565 family of
Reflective Memory real-time network products. The Reflective
Memory hub can automatically bypass ports when it detects a
loss of signal or the loss of valid synchronization patterns,
allowing the other nodes in the network to remain operational.
Since the optical ports are implemented with small form factor
pluggable (SFP) transceivers, only the required ports need to be
populated. The VMIACC-5595 SFP transceivers can be a
combination of either multimode (short distance) or single-mode
(long distance) transceivers. This feature permits a cost saving in
small networks as well as system optimization. For larger
networks, several VMIACC-5595 assemblies can be cascaded,
permitting a managed hub array with up to 256 nodes. Each
port regenerates the serial optical signal, eliminating the
problems with insertion losses and cable attenuation. Signal
regeneration also reduces jitter. The RS232 port gives you the
ability to monitor and control your Reflective Memory network
through a simple PC serial port. The Ethernet port feature allows
you to monitor and control the hub from great distances
through a local area network (LAN) or via a Web browser.
As an option, the VMIACC-5595 can be configured as a 19-inch
1U rack-mountable enclosure or as a desktop enclosure. The
universal power supply permits operation with nearly any
international power standard.
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.
An additional control register permits the transmitter of any port
to be manually disabled.
Front panel manual switches include a recessed momentary
reset switch and a Gang Select switch. The Gang Select switch
configures the VMIACC-5595 ports as one loop of eight ports or
two separate loops of four ports each.
Functional Characteristics
Multimode Port Wavelength: 830 to 860nm
Multimode Cable Length: 300m (maximum)
Single-Mode (10km) Port Wavelength: 1,300 to 1,335nm
Single-Mode (10km) Cable Length: 10km (maximum)
Single-Mode (80km) Port Wavelength: 1,540 to 1,570nm
Single-Mode (10km) Cable Length: 80km (maximum)
Dark on Dark: The 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).
Ethernet Controller: 10BaseT interface is compliant with
Transmission Control Protocol/Internet Protocol (TCP/IP)
standards. Each hub assembly will have a unique MAC address.
The hub assembly can operate on either a LAN or a wide area
network (WAN).
