LabVIEW uses graphical programming, whereas LabWindows enhances Microsoft C and
QuickBASIC. Both packages include extensive libraries for data acquisition, instrument control,
data analysis, and graphical data presentation.
Your National Instruments data acquisition board is shipped with the NI-DAQ software.
NI-DAQ has a library of functions that can be called from your application programming
environment. These functions include routines for analog input (A/D conversion), buffered data
acquisition (high speed A/D conversion), analog output (D/A conversion), waveform generation,
digital I/O, counter/timer, SCXI, RTSI, and self-calibration. NI-DAQ maintains a consistent
software interface among its different versions so you can switch between platforms with
minimal modifications to your code.
You can also use the SCXI-1163, together with the PC, AT, and MC data acquisition boards,
with NI-DAQ software for DOS/Windows/LabWindows. NI-DAQ software for
DOS/Windows/LabWindows comes with language interfaces for Professional BASIC, Turbo
Pascal, Turbo C, Turbo C++, Borland C++, and Microsoft C for DOS; and Visual Basic, Turbo
Pascal, Microsoft C with SDK, and Borland C++ for Windows. NI-DAQ software for
DOS/Windows/LabWindows is on high-density 5.25 in. and 3.5 in. diskettes.
You can use the SCXI-1163, together with the NB Series data acquisition boards, with
LabVIEW for Macintosh, a software system that features interactive graphics, a state-of-the-art
user interface, and a powerful graphical programming language. The LabVIEW Data
Acquisition VI Library, a series of VIs for using LabVIEW with National Instruments boards, is
included with LabVIEW. The LabVIEW Data Acquisition VI Library is functionally equivalent
to the NI-DAQ software for Macintosh.

Chapter 1 Introduction

The SCXI-1163 can accept data in two forms–serial and parallel. Serial data is transferred across
the SCXIbus using the Serial Peripheral Interface (SPI) protocol. Using serial communication,
one data acquisition board that is cabled to one SCXI module in an SCXI system can control the
digital communication for all the boards in the system. Parallel data is read from the rear
connector and transferred directly to the outputs at the front connector. No extra communication
through the rear connector is needed or permitted with parallel communication; thus you can
transfer parallel data to the outputs more rapidly than serial data. However, each module that is
utilizing parallel data transfers requires a separate data source, such as a data acquisition board.
You can configure the SCXI-1163 to primarily accept either parallel or serial data. In one
configuration, the rear connector accepts parallel data; in the other configuration, the rear
connector creates a serial communication link with the SCXIbus. Configure the module for
parallel data transfers when you want to send data directly from the rear connector to the outputs.
Configure the module for serial communication whenever you want to send only serial data to
the module. You must configure the module for serial communication if you want a data
acquisition board that is cabled to the module rear connector to control the SCXIbus.
When you cable the SCXI-1163 to a data acquisition board, you must also configure the
SCXI-1163 to recognize the board either as a DIO-type or an MIO-type board. DIO-type boards
are National Instruments boards that have only digital inputs and outputs. These boards include
the DIO-24, DIO-32F, and DIO-96. MIO-type boards are National Instruments boards that have
both analog and digital inputs and digital outputs. These boards consist of MIO boards; Lab-NB,
Lab-PC, Lab-PC+, and Lab-LC boards; and PC-LPM-16 boards. You can use either type for
serial communication; for parallel communication, you can use only the DIO-type boards.
However, when you use the DIO-24 for parallel communication, only channels 0 through 23 can
be controlled on the SCXI-1163.
To configure the SCXI-1163 module, use the five user-configurable jumpers shown in the parts
locator diagram, Figure 2-1. There is also one reserved jumper that should remain empty. To
change the configuration of the module, use the following procedure:
1. Remove the grounding screw of the top cover.
2. Snap out the top cover of the shield by placing a screwdriver in the groove at the bottom of
the module.
3. Remove the jumpers to be changed and replace them on the appropriate pins.
4. Record the new jumper settings on the SCXI-1163 Hardware Configuration Form in
Appendix F, Customer Communication.
5. Snap the top cover back in place.
6. Replace the grounding screw to ensure proper shielding.
The following warnings contain important safety information concerning hazardous voltages.
Warnings: Keep away from live circuits. Do not remove equipment covers or shields unless
you are trained to do so. If signal wires are connected to the module or terminal
block, dangerous voltages may exist even when the equipment is turned off. To
avoid dangerous electrical shock, do not perform procedures involving cover or
shield removal unless you are qualified to do so.

Do not operate damaged equipment. The safety protection features built into this
module can become impaired if the module becomes damaged in any way. If it is
damaged, turn the module off and do not use until service-trained personnel can
check its safety. If necessary, return the module to National Instruments for
service and repair to ensure that its safety is not compromised.
Do not substitute parts or modify equipment. Because of the danger of
introducing additional hazards, do not install unauthorized parts or modify the
module. Return the module to National Instruments for service and repair to
ensure that its safety features are not compromised.
When using the terminal block with high common-mode voltages, you must
insulate your signal wires appropriately. National Instruments is not liable for any
damages or injuries resulting from inadequate signal wire insulation.
When connecting or disconnecting signal lines to the SCXI-1326 terminal block
screw terminals, make sure the lines are powered off to prevent shock hazard.
Connections, including power signals to ground and vice versa, that exceed any of
the maximum signal ratings on the SCXI-1163 can damage any or all of the
boards connected to the SCXI chassis, the host computer, and the SCXI-1163
module. National Instruments is not liable for any damages or injuries resulting
from incorrect signal connections.
If high voltages (≥42 Vrms) are present, you must connect the safety earth ground
to the strain relief tab. This complies with UL 1244 and fully protects against
electric shock when the terminal block is not connected to the chassis. To connect
the safety earth ground to the strain relief tab, run an earth ground wire in the
cable from the signal source to the terminal block. National Instruments is not
liable for any damages or injuries resulting from inadequate safety earth ground
connections.
Jumper Use
Use the jumpers as follows:
• Reserved jumper
- Jumper W1 is reserved; do not connect this jumper.
• User-configurable jumpers
- Jumpers W2 and W3 select whether the SCXI-1163 is to be connected to a DIO-type
board or to an MIO-type board. If you are controlling the SCXI-1163 module via the
SCXI backplane, the position of these jumpers is irrelevant.
- Jumper W4 connects a pullup resistor to the SERDATOUT signal on the rear signal
connector.

- 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 kΩpullup 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 Timing Requirements and Communication Protocol section later in this chapter, and
Chapter 4, Register Descriptions, for information on reading the Module ID Register and the
Status registers. See Appendix E, SCXI-1163 Cabling, for the pin equivalences of the
SCXI-1163 rear signal connector and the data acquisition board I/O connector. The factory-
default setting is position DIO.
