-
Jumper W5 carries the SCXIbus MISO line, after buffering, to the SERDATOUT signal
on the rear signal connector.
-
Jumper W6 selects the primary operating mode, either serial or parallel, and configures
the rear connector accordingly.
Further configuration of the board is software controlled and is discussed later in this chapter.
Jumper Configuration
All five user-configurable jumpers (W2 through W6) on the SCXI-1163 are for digital
communication between the data acquisition board and the SCXI-1163 module.
The SCXI-1163 has two jumpers, W2 and W3, that indicate to the module what type of data
acquisition board is to be connected to the module rear signal connector. The SCXI-1163 also
has two jumpers, W4 and W5, for communication between the data acquisition board and the
SCXIbus. There is also one jumper, W6, that you use to set the primary mode of operation. See
Tables 2-1 and 2-2 for the description and configuration of the jumper settings.
Jumpers W2 and W3
You can use two types of data acquisition boards to communicate with the SCXI-1163–DIO-type
boards and MIO-type boards. Jumpers W2 and W3 configure the rear connector to accept
signals from either a DIO-type or an MIO-type data acquisition board. Both jumpers have labels
indicating the DIO and MIO configurations. If you want to use the SCXI-1163 with a DIO-type
board, place the jumpers in the D position. This position is the factory setting. If you want to
use the SCXI-1163 with an MIO-type board, place the jumpers in the M position. If you are
controlling the SCXI-1163 via the SCXI backplane and are not using the rear connector, the
position of these jumpers is irrelevant.
Jumper W4
Position A connects a 2.2 k pullup resistor to the SERDATOUT line. This is the factory-
default setting. Position B does not connect the pullup resistor to the SERDATOUT line.
Jumper W5
Position DIO connects the SCXIbus MISO line, after buffering, to the SERDATOUT pin of the
rear signal connector when used with a DIO-type board. Position MIO connects the SCXIbus
MISO line, after buffering, to the SERDATOUT pin of the rear signal connector when used with
an MIO-type board. In these settings, when you have set jumper W4 properly, the data
acquisition board can read the Module ID Register or the Status Registers of the SCXI-1163.
See the

Register
Descriptions, for information on reading the Module ID Register and the
Status registers. See Appendix E,
SCXI-1163 rear signal connector and the data acquisition board I/O connector. The factory-
default setting is position DIO.
