SCGT Init block

Mask

Description

This function initializes and opens the card, such that it is accessible to perform other operations like read, write etc. on the GT200 and creates a shared memory on the target. Shared memory created on the target has the addresses of PCI slot and handle for the GT200 card. This shared memory is used by other blocks to perform their operations. This block is also responsible for closing the card and unmapping the memory on reset. If two or more cards are present on the target then for every card there should be separate SCGT Init block. PCI slot number should be separated for each card.

Parameters

Node ID

The network supports up to 255 nodes. Each node on the GT network has an associated node ID. Node refers to each GT200 card. When a node transmits a native packet, it sends its node ID as part of the packet header. When a node receives a data packet, it compares its own node ID with the node ID in the received packet header. If the node IDs match, the packet is identified as a native packet and is not retransmitted.

PCI slot

If two or more boards of same type are physically present in the target PC, enter the PCI slot number of the board associated with this driver block (if only one card is present in a target PCI slot no will be 0).

Inputs

This block has no inputs.

Outputs
