NI SCXI-1163R Jumpers

You can configure the NI SCXI-1163R to operate in serial or parallel mode. You can cable and control the NI SCXI-1163 with an E Series, NI 4021, NI DMM, or DIO device. There are five user-configurable jumpers. If the controller is not cabled to the module, do not change the jumper settings.

In serial mode, only one module per chassis is connected to the controller, which allows communication with all other modules. Only the jumper settings on the NI SCXI-1163R module are relevant.

In parallel mode, a DIO device can only be connected to one NI SCXI-1163R. Signals at the rear signal connector directly control the states of the solid-state relays. A logic low (or 0) on the rear connector closes the corresponding relay. Likewise, a logic high (or 1) opens the relay. In parallel mode, the controller cannot communicate with the SCXI chassis or with other SCXI modules. Therefore, if multiple NI SCXI-1163R modules in an SCXI system are to be used in parallel mode, the rear signal of each module must be connected to separate DIO devices.

Jumper Settings

Factory settings are in Bold.

W2	D (controller is DIO device) M (controller is E Series device, NI 4021, National Instruments DMM)
W3	D (controller is DIO device) M (controller is E Series device, NI 4021, National Instruments DMM)
W4	A (single chassis) B (multiple chassis)
W5	DIO (serial mode with DIO controller) M (controller is E Series device, NI 4021, National Instruments DMM) PAR (parallel mode with DIO controller)
W6	S (set primary mode of operation to serial) P (set primary mode of operation to parallel)

Complete the following steps to correctly set the jumpers.

For a single chassis in serial mode:

1. Set W2, W3, and W5 according to the controller.
2. Set W4 to A.
3. Set W6 to S.

For multiple chassis:

1. W2, W3, and W5 should be set according to the controller.
2. W4 on one cabled module should be set to A, and W4 on all other cabled modules should be set to B.
3. W6 should be set to S.

For parallel mode:

1. Set W2 and W3 to D.
2. Set W4 to A.
3. Set W5 to PAR.
4. Set W6 to P.
