Chapter 2 Configuration and Installation© National Instruments Corporation 2-5 SCXI-1163 User Manual- Jumper W5 carries the SCXIbus MISO line, after buffering, to the SERDATOUT signalon the rear signal connector.- Jumper W6 selects the primary operating mode, either serial or parallel, and configuresthe rear connector accordingly.Further configuration of the board is software controlled and is discussed later in this chapter.Jumper ConfigurationAll five user-configurable jumpers (W2 through W6) on the SCXI-1163 are for digitalcommunication 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 dataacquisition board is to be connected to the module rear signal connector. The SCXI-1163 alsohas two jumpers, W4 and W5, for communication between the data acquisition board and theSCXIbus. There is also one jumper, W6, that you use to set the primary mode of operation. SeeTables 2-1 and 2-2 for the description and configuration of the jumper settings.Jumpers W2 and W3You can use two types of data acquisition boards to communicate with the SCXI-1163–DIO-typeboards and MIO-type boards. Jumpers W2 and W3 configure the rear connector to acceptsignals from either a DIO-type or an MIO-type data acquisition board. Both jumpers have labelsindicating the DIO and MIO configurations. If you want to use the SCXI-1163 with a DIO-typeboard, place the jumpers in the D position. This position is the factory setting. If you want touse the SCXI-1163 with an MIO-type board, place the jumpers in the M position. If you arecontrolling the SCXI-1163 via the SCXI backplane and are not using the rear connector, theposition of these jumpers is irrelevant.Jumper W4Position A connects a 2.2 kΩ 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 W5Position DIO connects the SCXIbus MISO line, after buffering, to the SERDATOUT pin of therear signal connector when used with a DIO-type board. Position MIO connects the SCXIbusMISO line, after buffering, to the SERDATOUT pin of the rear signal connector when used withan MIO-type board. In these settings, when you have set jumper W4 properly, the dataacquisition board can read the Module ID Register or the Status Registers of the SCXI-1163.See the Timing Requirements and Communication Protocol section later in this chapter, andChapter 4, Register Descriptions, for information on reading the Module ID Register and theStatus registers. See Appendix E, SCXI-1163 Cabling, for the pin equivalences of theSCXI-1163 rear signal connector and the data acquisition board I/O connector. The factory-default setting is position DIO.
