2. PRODUCT OVERVIEW
2.1 Overview
Curtiss-Wright Controls GT200 VME card is a single-slot, single-card computer that
utilizes a Motorola MPC8540 I/O processor, Tundra Tsi148 VME to PCI/X Bridge, 256
MB of DDR SDRAM and 128 MB of Flash memory. The GT200 VME card has one
PMC slot in which a GT200 PMC card is installed.

2.1.1 Features
The GT200 VME has the following features:
• Supports concurrent network and host accesses with no loss of network data or
need to implement network flow control
• Status LEDs that report link status
• Two Small Form Factor Pluggable (SFP) media options available— short
wavelength laser (850 nm) and long wavelength laser (1300 nm)
• 2.5 Gbps fiber-optic interface with redundant transceiver option for network
topology redundancy
• Operates with the LinkXchange family of switches (2.5 Gbps or faster)
• Tundra Tsi148TM PCI/X-to-VME Bridge
• Supports VME legacy protocols
Copyright 2005 2-1 GT200 VME Hardware Reference

PRODUCT OVERVIEW
• Two independent single channel DMA controllers
• Supports 2eSST and 2eVME protocols
• RS-232 serial port
• Two Ethernet interfaces, one 10/100/1000BaseTX and one 10/100BaseTX
• VME64x form factor, will operate in VME64 3-row backplane
2.2 SFP Media Options
The physical media interface of the GT200 design uses SFP transceiver modules. These
modules are hot swappable, providing an efficient way to modify the media interface
configuration as needed.
Two basic SFP media options are available for the GT200. These media options are a
long wavelength laser (1300 nm) and short wavelength laser (850 nm). All cards use a
Duplex LC style connector available from most major cable manufacturers.
Figure 2-2 SFP Transceiver Module
Long wavelength laser interconnections are recommended for distances longer than 250
meters, as loss in multimode fiber degrades connections with short wavelength lasers past
this distance.
The short wavelength version is useful for intrasystem connections, where you are
connecting between cards on the same backplane. It is also suited for short reach
intersystem connections (< 250 m).
The SFP transceivers comply with the Small Form-factor Pluggable transceiver
MultiSource Agreement (SFP MSA) to ensure compatibility between the different
transceiver manufacturers.

PRODUCT OVERVIEW
2.2.1 LED Descriptions
Six pairs of status LEDs along with RJ-45 connector LEDs are visible from the front
panel of the GT200 VME card. The front panel LEDs are shown in Figure 2-3.
From the left end of the panel:
Power ON LED (Green) – Enabled when power is applied to the card
Card Fail LED (Red) – Turns off when board has successfully booted
Ethernet 10/100/1000
• Connector – Tx activity LED (Green) & Rx activity LED (Green)
• 100 Mbps speed indicator LED (Green)
• 1Gbps speed indicator LED (Green)
Ethernet 10/100
• Connector – Tx activity LED (Yellow) & Rx activity LED (Green)
• 10 Mbps speed indicator LED (Green)
• 100 Mbps speed indicator LED (Green)
Fiber Communication Status LEDs
• The Link Select LED (LS) indicates which channel of the GT200 board is
selected. When the LED is off, channel 0 is selected. When the LED is on,
channel 1 is selected.
• The Link Up LED (LU) turns on when the selected channel is receiving a valid
GT200 signal.
• The Signal Detect LEDs (R0, R1) indicate a signal is being received by the
corresponding transceiver.
• The Laser Enable LEDs (T0, T1) indicate the corresponding transceiver is turned
on.

PRODUCT OVERVIEW
2.3 Topologies
There are various topologies for the GT200 VME card. These topologies should cover
most customer applications, though if another topology is desired contact Curtiss-Wright
Controls, Inc. Technical Support to see if it is possible. The topologies are:
Non-redundant ring
Redundant ring
Point-to-Point
Daisy Chain
Monitoring
Switch ring
Redundant switch ring
2.3.1 Non-Redundant Ring
This is the simplest of the topologies, with a single transmit/receive connection per node.
Any data written to one node is broadcast to all nodes. A break in one node of fiber
caused the ring to be broken. This topology would be used in a system where a failure in
the ring is not critical.

…

0
2.3.2 Redundant Ring
This topology is the same as a non-redundant ring; only a second ring is added using the
second transceiver to create a ring with data flowing in the opposite direction. A failure
in one of the rings does not prevent data from flowing to all the nodes. This topology
would be used in critical systems where a break in the ring cannot be tolerated.

2.3.3 Point-to-Point
This is a special version of the non-redundant ring where there are just two nodes.

2.3.4 Daisy Chain
This topology only allows data to flow in one direction. This topology is used where data
does not need to be sent back to the sending node. The first node in the chain could be a
remote sensor sending data to several receiving nodes.
2 53

2.3.5 Monitoring
A monitoring topology is a non-redundant ring with one of the nodes transmitting the
data on its second transceiver to a monitoring node. The monitoring node can be used to
watch the status of the ring and check the ring’s health.
