NI SCXI-1127/1128 2-Wire 4×8 Matrix Topology

When using the NI SCXI-1127/1128 as a 2-wire 4×8 matrix, connect your signals using the NI SCXI-1332 terminal block. In this topology, connect your positive and negative lead to CLx± or Rx± inside the NI SCXI-1332 terminal block. The following figure represents the NI SCXI-1127/1128 in the 2-wire 4×8 matrix topology.

Making a Connection

When using the niSwitch Connect Channels VI or the niSwitch_Connect function with c0 and r0 during immediate operations, the signal connected to CL0 ± is routed to R0 ±. To route R0 ± to AB0 ±, use niSwitch Connect Channels VI or the niSwitch_Connect function with r0 and ab0.
