The following figure represents the NI 2811A/B (NI 2811) in the 1-wire 8×21 matrix topology.

Making a Connection

The immediate operation, niSwitch Connect Channels VI or the niSwitch_Connect function with parameters card1r1 and c1, results in the signal connected to CARD1R1 being routed to C1.

Pinout

The following figure identifies the pins for the NI 2811.

Note   Dual connections separated by a slash in the format of TYPE A SIGNAL(A)/TYPE B SIGNAL(B) indicate pins that connect to a different signal depending on the card type. For example, a pin labeled AB0(A)/NO CONNECT(B) would connect to AB0 on a type A card and would make no connection on a type B card.
