1-Wire Quad 4×32 Matrix
Software name: 2532/1-Wire Quad 4x32 Matrix (NISWITCH_TOPOLOGY_2532_1_WIRE_QUAD_4X32_MATRIX)
Hardware Diagram
The NI TB-2646B terminal block creates a 1-wire quad 4×32 matrix topology with the module.
Making a Connection
Both the scanning command, b0r2->b0c1;, and the immediate operation, niSwitch Connect Channels VI or the niSwitch_Connect function with parameters b0r2 and b0c1, result in the following connection:
- signal connected to B0R2 is routed to B0C1
Terminal Block Connections
The NI TB-2646B terminal block connects banks of the module to create the 1-wire quad 4×32 matrix topology.
