Modify the STsc data paths configuration file, datapaths.ini, to define the STsc data paths between the HSS ports and ETH ports of each stream translation module managed by a given instance of STsc.

  • Sample File—datapaths.ini
  • Sample File Location—<Program Files>\National Instruments\NI STsc

    • [Datapath.<Alias>] Section

    Use [Datapath.<Alias>] sections to define each data path, in the format of "Datapath.<Alias>" where <Alias> is the name you want to assign to that data path.

    Table 17. [Datapath.<Alias>] Key Value Pairs
    Key Value Default Value Required?
    Instrument The stream translation module device name, as configured in Hardware Configuration Utility. — Required
    Direction The high-speed serial connection direction. Valid values are:
    • "HSS_TO_NIC"
    • "NIC_TO_HSS"
    		 — Required
    HssConnection The connection of the physical high-speed serial connection. Valid inputs are:
    • 0
    • 1
    Refer to the High-Speed Serial Connection Pairs between the VST(s) and Stream Translation Module table in Cabling for High-Speed Data Movement for information about the inputs.    		 — Required
    LocalAddress The 4-byte IPv4 address and port number (separated by a colon) that is used by the stream translation module for this datapath. — Required
    RemoteAddress   The 4-byte IPv4 address and port number (separated by a colon) that is used by the remote 100 GbE RDMA-enabled device connected to the stream translation module for this datapath. — Only required when Direction is set to "NIC_TO_HSS"
    Note RemoteAddress and LocalAddress must be on the same 3-byte subnet.

    Example: 

    [datapath.my_data_path_1]  
Instrument = "8290_00"  
Direction = "HSS_TO_NIC"  
HssConnection = 0  
LocalAddress = "192.168.1.1:60000"  
RemoteAddress = "192.168.1.2:60000"  

[datapath.my_data_path_2]  
Instrument = "8290_01"  
Direction = "NIC_TO_HSS"   
HssConnection = 1  
LocalAddress = "192.168.3.1:60000"
