NI SCXI-1127/1128 Independent Topology

When using the NI SCXI-1127/1128 in the independent topology, connect your signals using the NI SCXI-1331 terminal block. In this topology, you utilize the full routing capabilities of the NI SCXI-1127/1128. The following figure represents the NI SCXI-1127/1128 in the independent topology.

Making a Connection

When using the Traditional NI-DAQ (Legacy) resource name with the independent topology, control the individual relays using the niSwitch Relay Control VI or the niSwitch_RelayControl function. When using the NI-DAQmx resource name with the independent topology, you can also use the niSwitch Connect Channels VI or the niSwitch_Connect function to control the relays. Refer to the NI SCXI-1127/1128 hardware diagram for relay names.

Note  If you are using the NI SCXI-1127/1128 with Traditional DAQ in independent topology and 64 signals, refer to Knowledge Base #2W3A99HQ at ni.com/support for more information.
