Overview
Introduction
The VMIACC-5595* is a managed hub, designed to operate with GE’s VMIxxx-5565
Reflective Memory products. Without a hub device, the Reflective Memory nodes
must be networked together in a daisy-chained loop. In the hub-less configuration if
one node becomes inoperable, the entire loop becomes disabled. When the
VMIACC-5595 hub is incorporated into the network, the network is converted from a
loop to a star configuration. In the star configuration if one node becomes inoperative,
that node is bypassed by the VMIACC-5595 and the remaining nodes on the network
remain operational. When a network consists of a large number of nodes or if the
nodes are widely dispersed over an area, the star configuration is easier to build and
maintain.
The VMIACC-5595 automatically bypasses a port when it detects a loss of signal or
the absence of a valid synchronization pattern, allowing the remaining nodes to
continue to operate. Each port on the VMIACC-5595 regenerates the serial optical
signal, eliminating problems with insertion losses and cable attenuation. Signal
regeneration also reduces jitter.
The optical ports are implemented with Small Form-Factor Pluggable (SFP)
transceivers (see Figure 1 on page 8). Only the required ports need to be populated.
The SFP transceivers can be a mix of multimode (short distance) or single-mode (long
distance) transceivers. This feature permits a cost savings in small networks, as well
as system optimization. For larger networks, several VMIACC-5595 hubs can be
cascaded, permitting a managed hub array with up to 256 nodes.
An RS232 port permits local monitoring and control of the Reflective Memory
network using a standard PC serial port. The Ethernet port (10BaseT) can be used to
monitor and control the hub from great distances through a Local Area Network
(LAN) or with the use of a Web browser.
The VMIACC-5595 is available 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. Figure 2 on page 9 is a functional block diagram of the
VMIACC-5595 Hub Assembly.

The VMIACC-5595 can operate without the use of the Ethernet port or the RS232 port.
When first activated, the VMIACC-5595 operates using the factory default
configuration with each optical port in the auto bypass mode and the bypass is based
on detection of Loss of Signal (LOS).

Basic Operation
The default factory configuration for the VMIACC-5595 is to automatically bypass
ports due to the loss of a signal (light) at the receiver or the absence of a valid
synchronization pattern, without any interface through the Ethernet port or RS232
port.
Three LEDs adjacent to each port give a visual indication of the port status. Status
information and modes of operation are available using the Ethernet port and your
standard Web Browser or using the RS232 port and any RS232 terminal interface.
Status information includes:
• Detection of installed transceivers
• Detection of signal (light)
• Detection of valid synchronization patterns (multiple or single)
The Hub Assembly allows for the bypassing of a port to be based on the absence of
either single/multiple synchronization patterns or the loss of a signal (light). Also,
each port can be manually forced active or bypassed regardless of the status
indicators. Finally, each port transmitter can individually be disabled without
shutting down the entire Hub.

Both the serial port interface and the Ethernet interface can be used at the same time.
Multiple Ethernet users are also possible. At times this feature is actually useful. It can
be tedious to temporarily change your PC’s Ethernet port to a range that matches the
default factory settings, if restoring the defaults becomes necessary. On some
machines, it could require a time consuming multi-reboot process. By using the serial
port only to re-establish the IP settings, the process becomes easier.
The total signal propagation delay through the entire VMIACC-5595 hub is
25 nanoseconds — equivalent to the delay through approximately 18 feet of cable.
The switching time depends on the Detection Mode used: LOS, Single Sync mode or
Multi-Sync mode.
For the Single Sync Detect Mode, the auto bypass switch delay will be approximately
0 to 15.5µsec. For the Multi-Sync mode, the auto bypass switch delay is approximately
4 times 15.5µsec or 62µsec provided four consecutive invalid sync periods occur. The
auto bypass OFF switching delay for the LOS Detect Mode is approximately 100µsec.
The auto bypass ON switching delay for the LOS Detect Mode is approximately
1.25msec. Also note that upon power-up of the hub, all ports will default to bypass
ON.
NOTE: The switching time values are difficult to measure accurately, so they are
estimated and based on component specifications.
The power up delay of the VMIACC-5595 is less than 2 seconds. This is measured
from the time power is first applied to the time the Ethernet Link light is truly
asserted. The last event to complete at power up is the boot of the Ethernet module’s
imbedded processor. The optical ports are operational in the default mode (auto
bypass based on LOS) in approximately 1 second after power is applied. The bypass
circuitry of this hub is not passive. Power must be applied to the unit before it will
pass network data.
All the control settings, not just the communication settings, are stored in non-volatile
memory. If power is lost or interrupted, the hub will return to the last good
configuration, once the processor boot cycle is complete.

LAN - This is the 10Base-T Ethernet port, using a standard RJ45 receptacle. The
connector has two LEDs along its top edge. The LED labeled LNK is the link status
and the LED label ACT is the link activity. The Ethernet interface is compliant with the
Transmission Control Protocol/Internet Protocol (TCP/IP) specification. Each hub
assembly has a unique Internet Protocol (IP) address that can be altered by the user
(see Figure 1-2 on page 17 for the location of the switch) or reset to the default
settings. The hub assembly can operate on either a Local Area Network (LAN) or
Wide Area Network (WAN).
RS232 – RS232 is a PC compatible standard female DB9 serial port, supporting baud
rates up to 19.2 kbps. The RS232 port is used for local monitoring and control of the
hub. Depending on the application, it can also be used as the primary control port.
Auxiliary Manual Switch (S4)
Switch S4 is a bank of four dip switches located on the circuit board of the
VMIACC-5595 (see Figure 1-2 and Figure 1-3 on page 17). The dip switch is used to
restore the hub to the default settings.
NOTE: If the user forgets the login password or if the hub communication settings
are changed in such a way that the user can no longer communicate with the unit,
then S4 auxiliary manual dip switch is used to restore the hub to its default
configuration values.

For each of the four dip switches, only position number 1 is used, the other three are
reserved. When the switch is in the “OFF” position, the corresponding direct I/O
signal will read high (1). Likewise, when the switch is in the “ON” position, the
corresponding direct I/O signal will read low (0). Table 1-1 below lists the dip switch
number and description.
To restore the factory default configuration, place switch S4 position 1 to the ON
position and then cycle the power or press the reset button. Each time the unit leaves
reset and senses that switch S4 position 1 is in the ON position, it will restore the unit
settings to the factory default values.
The default values are:
• Password is “password”
• IP address is 10.0.0.1
• IP netmask is 255.255.255.0
• IP gateway is 0.0.0.0
• Serial port baud rate is 9600
• Transmitters are enabled
• All ports operate in the auto bypass mode
• All ports are bypass based on Lost of Signal (LOS) detection
• All ports are set to ‘Dark on Dark’ (off)
CAUTION: Do not leave switch S4 in the ON position indefinitely. Otherwise, every
time the unit is reset or power cycled the unit will revert to the defaults settings and
your desired configuration will be lost.
Jumper E4 is for factory use only. Leave the jumper shunt of E4 between pins 1 and 2.
Both the serial and the Ethernet port will not operate if the E4 jumper is altered.

Front Panel Status Indicators, Switches and Ports
Status LEDs – The Status LEDs provide a limited status of the hub. See Table 1-2
below for a description of the status LEDs:
RST – RST is a manual push button reset switch, which will reset the entire
VMIACC-5595 hub including the 10Base-T Ethernet module.
GANG 1x8-2x4 – The GANG switch configures the hub as either 1 group of 8 ports
(labeled 1x8) or 2 groups of 4 ports (labeled 2x4). When operating in the 2x4
configuration, ports 0 through 3 form one group and ports 4 through 7 form the
second group. The two groups of ports operate independent of each other. To select
either setup move the switch either left or right. Moving the switch to the right sets
the hub to 2x4, moving the switch to the left sets the hub for 1x8.
PORTs 0 through 7 – There are eight positions available for the optical Small
Form-Factor Pluggable (SFP) transceivers. Each port can contain an actual transceiver,
depending on the option ordered. Ports that do not have a transceiver installed will
have a filler plug to avoid dust contamination and reduce EMI emissions, and will
automatically be bypassed. The SFP transceivers accept the standard LC type
fiber-optic connectors, either the simplex (single) or duplex (double) configuration.
The LC receptacle labeled TX is the transmitter and the receptacle labeled RX is the
receiver.
Port Status LEDs - The three LEDs to the right of each port indicate the current status
of that port. See Table 1-3 below for a detail description of the Port Status LEDs.
