    Replace these rubber boots when cables are not in use or if the node must be returned to the factory. Attach the fiber-optic cables to the connectors on the GT200 card. Figure 3-3 and Figure 3-4 depict the types of fiber-optic connectors needed for the GT200 card.

  • Page 28: Troubleshooting

    If the system does not boot correctly, power down the machine, reseat the card, double- check cable connections, and turn the system back on. If problems persist, contact Curtiss-Wright Controls, Inc. Technical Support at (800) 252-5601 or DTN_support@curtisswright.com for assistance.

  • Page 29: Operation

    4. OPERATION 4.1 Overview The GT200 Network is a shared-memory system. Every computer on the network has a local copy of all global data, which is passed to all the network computers anytime a write occurs. The network protocol is implemented in the GT200 hardware and therefore no software overhead is required to retrieve this information from the network.

  • Page 30: Ring Topology

    OPERATION 4.2.2 Ring Topology The GT200 Network is a ring topology network. The ring topology supports circuit- switch operation for topology reconfiguration and fault isolation. Ring protocol is register insertion with source message removal. Data is transmitted at a maximum of 2.5 Gbps over fiber-optic cables. There is an approximate 0.4µs (minimum) latency at each node as the frame works its way around...

  • Page 31: Interface Standards

    The maximum fiber length supported is 10 km based on the ring size, media used, and status messaging. 4.2.5 Interface Standards The GT200 interface is a proprietary interface running at 2.5Gbps. The interface uses both 8B/10B encoding and CRC32 error checking. 4.2.6 Network Framing Frame types include: •...

  • Page 32: Latency

    When performing a transfer of user buffer to/from network memory, the driver works in conjunction with the operating system and the GT200, and may break the user buffer into multiple DMA transfers. This is a result of paging, physical memory requirements, and the need to have a contiguous memory region for the DMA descriptors.

    SW function) or via an interrupt flag (separate chain entry) on DMA write operations. The HBI and HUI events are stored in a queue located on the GT200 card. HBI and HUI events are stored in the order of reception. The receiving node saves the source node ID, interrupt vector, and interrupt type (broadcast with interrupt level or unicast).

    Many users are still using older PCI-based machines that only support 5-volt PCI signaling voltages. By installing a GT200 PMC board onto the 5-volt PCI to PMC adapter the user now has a 5-volt signaling PCI board that can be used in older legacy systems.
