Chapter 2
Configuration and Installation
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.
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.

Configuration and Installation
Chapter 2
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

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
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 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 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.
SCXI-1163 rear signal connector and the data acquisition board I/O connector. The factory-
default setting is position DIO.

Chapter 2
Position PAR disconnects SERDATOUT from the SCXIbus MISO line. Use this position when
you will connect the module in parallel to a data acquisition board.
Using Jumpers W4 and W5
If a module is not connected to a data acquisition board, the positions of jumpers W4 and W5 are
irrelevant. Jumpers W4 and W5 give the data acquisition board access to the MISO line on the
backplane. You use the MISO line to read the Module ID Register of modules. National
Instruments software does not use this ability. You must indicate to the software which module
is in which slot. In addition to reading the Module ID Register, you can use the MISO line on
the SCXI-1163 to read the Status Registers, which indicate the primary and output modes of
operation. National Instruments software uses this feature.
The SERDATOUT line is driven with an open-collector driver, which is a driver that actively
drives low or goes to a high-impedance state, relying on a pullup resistor to make the signal line
go high. When using a single chassis, set jumper W4 to position A on the SCXI-1163 that is
connected to the data acquisition board and set jumper W5 to DIO or MIO. In this setting, the
module drives MISO to SERDATOUT and connects the necessary pullup resistor to the
SERDATOUT line. When using multiple chassis, set jumper W5 to position DIO or MIO on all
of the SCXI-1163s that are cabled to the data acquisition board. Only one of the SCXI-1163s
that are cabled to the data acquisition board should have jumper W4 in position A. It does not
matter which of the SCXI-1163s that are cabled to the data acquisition board has the pullup
connected. You should set jumper W4 to position B on all of the other SCXI-1163 modules that
are cabled to the data acquisition board. If you attach too many pullup resistors to the
SERDATOUT line, the drivers cannot drive the line low.
Jumper W6
Jumper W6 sets the primary mode of operation to either serial mode or parallel mode and
configures the rear connector accordingly. With the primary mode of operation set to parallel,
the rear connector is configured to accept parallel data from a DIO board. With the primary
mode of operation set to serial, the rear connector is configured to allow serial communication
between a data acquisition board and the SCXIbus.
To set the primary mode of operation to parallel, set jumper W6 to position P. In this mode,
jumper W5 should be set to PAR to prevent the MISO line from inadvertently driving one of the
outputs. To set the primary mode of operation to serial, set jumper W6 to position S.

The SCXI-1163 consists of eight ports of four optically isolated digital outputs. Each port of
outputs has a separate connection for a +5 V power supply (Vcc) and for a ground (GND) for
that port. Digital logic powered by the port Vccs and referenced to the port grounds drives the
outputs of each port; therefore, for any port of outputs to work, you must connect a Vcc and a
ground to that particular port. The outputs work on a +5 V supply (in other words, Vcc must be
5 V above ground for any given port), and supply voltages of 7 V or more may damage the
output circuitry. It is recommended you keep the Vcc between 4.5 and 5.5 V above ground. The
Vcc, ground, and four outputs of one port are isolated from the Vcc, ground, and four outputs of
any other port, as well as from the internal circuitry of the module.
All signals have a working isolation voltage of 450 VAC or VDC referenced to chassis earth
ground and to signals of other ports. There is no isolation barrier between signals of the same
port. The signal-to-ground and port-to-port breakdown voltage is 1,900 Vrms.
Terminal Block
To connect the signals to the SCXI-1163 outputs, you can use a National Instruments terminal
block with screw terminals for easy connection.
SCXI-1326 Terminal Block
The SCXI-1326 front terminal block consists of a shielded board with supports to connect it to
the SCXI-1163 front connector. Forty-eight screw terminals are available for easy signal
connection.
When connecting your signals to the SCXI-1326 for use with the SCXI-1163, you should follow
The following warnings contain important safety information concerning hazardous voltages.
Warnings: 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.

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.
Signal Connection
To connect the signal to the terminal block, 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 terminal block.
3. Slide the signal wires one at a time through the front panel strain relief. You can add
insulation or padding if necessary.
4. Connect the wires to the screw terminals, making sure you connect a Vcc and a ground to
every port you use.
5. Tighten the strain relief by tightening the larger screws.
6. Snap the top cover back in place.
7. Replace the grounding screw to ensure proper shielding.

The signals on the rear signal connector are digital I/O signals. Signal connection guidelines for
each of these groups are given in the following section.
Serial I/O Signal Connections
Pins 24 through 27, 29, 31, 37, 47, and 50 constitute the digital I/O lines of the rear signal
connector when it is configured for serial communication. The lines are divided into three
categories–the digital input signals, the digital output signals, and the digital timing signals.
The digital input signals are pins 24 or 50, 25, 27, 29, and 31 or 37. The data acquisition board
uses these pins to configure the SCXI module that is under data acquisition board control. Each
digital line emulates the SCXIbus communication signals as follows:
•
Pin 24 or 50 is the digital ground reference for the data acquisition board digital signals and
is tied to the module digital ground. Pins 24 and 50 are not tied together.
-
Pin 24 is for MIO-type boards when SCXI-1163 jumpers W2 and W3 are in the MIO
position.
-
Pin 50 is for DIO-type boards when SCXI-1163 jumpers W2 and W3 are in the DIO
position.
•
•
Pin 25 is SERDATIN and is equivalent to the SCXIbus MOSI serial data input line.
Pin 27 is DAQD*/A and is equivalent to the SCXIbus D*/A line. It indicates to the module
whether the incoming serial stream on SERDATIN is data (DAQD*/A = 0) or address
(DAQD*/A = 1) information.
•
•
Pin 29 is SLOT0SEL* and is equivalent to the SCXIbus INTR* line. It indicates whether the
data on the SERDATIN line is being sent to Slot 0 (SLOT0SEL* = 0) or to a module
(SLOT0SEL* = 1).
Pin 31 or 37 is SERCLK and is equivalent to the SCXIbus SPICLK line. Either pin clocks
the serial data on the SERDATIN line into the module registers. Pins 31 and 37 are not tied
together.
-
Pin 31 is for DIO-type boards when SCXI-1163 jumpers W2 and W3 are in the DIO
position.
-
Pin 37 is for MIO-type boards when SCXI-1163 jumpers W2 and W3 are in the MIO
position.
The digital output signal is pin 26 or 47:
•
Pin 26 or 47 is SERDATOUT and is equivalent to SCXIbus MISO when jumper W5 is in
either the MIO or DIO position. Pins 26 and 47 are not tied together.
-
-
Pin 26 is for MIO-type boards when SCXI-1163 jumpers W2 and W3 are in the MIO

When you configure the SCXI-1163 for an MIO-type board, the digital I/O signals of the
SCXI-1163 match the digital I/O lines of the MIO board. When you use the SCXI-1163 with an
SCXI-1341, SCXI-1342, or SCXI-1344 cable assembly, the SCXI-1163 signals match the digital
lines of the Lab-NB/Lab-PC/Lab-PC+ boards, the PC-LPM-16 board, and the Lab-LC board,
respectively. When you configure the SCXI-1163 for a DIO-type board, the digital I/O signals
of the SCXI-1163 match the digital I/O lines of the DIO-24 and DIO-96. When used with an
SCXI-1348 cable assembly, the SCXI-1163 signals match the digital lines of the DIO-32F.

Timing Requirements and Communication Protocol
Communication Signals
This section describes the methods for communicating on the Serial Peripheral Interface (SPI)
bus and their timing requirements. The communication signals are SERDATIN, DAQD*/A,
SLOT0SEL*, SERDATOUT, and SERCLK. Because SS* is produced by Slot 0 according to
data acquisition board programming, this section also discusses SS* timing relationships. For
The data acquisition board writes a slot-select number to Slot 0 to determine to which slot it will
talk. In the case of an SCXI-1001 chassis, this write also determines to which chassis the data
acquisition board will talk.
Use the following procedure for selecting a slot in a particular chassis. Figure 2-5 shows the
timing of this procedure with the example of selecting Slot 11 in Chassis 9. Notice that the
factory-default chassis address for the SCXI-1000 is address 0. For information on changing the
address of your chassis, consult the SCXI-1000/1001 User Manual. An SCXI-1000 chassis will
respond to any chassis number.

To write the 16-bit slot-select number to Slot 0, follow these steps:
1. Initial conditions:
SERDATIN = don't care.
DAQD*/A = 1.
SLOT0SEL* = 1.
SERCLK = 1.
2. Clear SLOT0SEL* to 0. This deasserts all SS* lines to all modules in all chassis.
3. For each bit, starting with the MSB, perform the following action:
a. SERDATIN = bit to be sent. These bits are the data that are being written to the
Slot-Select Register.
b. SERCLK = 0.
c. SERCLK = 1. This rising edge clocks the data.
4. Set to 1. This asserts the SS* line of the module whose slot number was written to Slot 0. If
you are using multiple chassis, only the appropriate slot in the chassis whose address
corresponds to the written chassis number is selected. When no communication is taking
place between the data acquisition board and any modules, write zero to the Slot-Select
Register to ensure that no accidental writes occur.

After the Address Handler has been written to, an address line of a register has been asserted. At
that stage you can write to the SCXI-1163 Data Register and read from its Module ID Register
or Status Registers using the following protocols. The contents of the Module ID Register are
reinitialized by deasserting Slot-Select. After the 32 bits of data are read from the Module ID
Register, further data will be zeros until reinitialization occurs. The Data Register latches its data
to the outputs when it is deselected.

When the primary mode of operation is jumper configured to serial mode, the SCXI-1163
module converts the data acquisition board signals to open-collector signals on the backplane of
the SCXI chassis. For the data acquisition board to talk to a slot, the board must first assert the
SS* for that slot. To do this, assert INTR* low, write a 16-bit number over MOSI corresponding
to the desired slot (and chassis if you are using an SCXI-1001 chassis), and release INTR* high.
At this point, the SS* of the desired slot is asserted low and the data acquisition board can
communicate with the module in that slot according to the SPI protocol.

Theory of Operation
This circuitry is divided into an SCXI digital interface section and two signal routing sections.
The SCXI digital interface buffers signals from the SCXIbus to the module and drives signals
from the module onto the SCXIbus.
The rear connector routing circuit determines the function of the rear connector from the jumper-
configured primary operating mode. When the primary operating mode is serial, the signals from
the rear connector are routed to the SCXI digital interface. When the primary operating mode is
parallel, the signals from the rear connector are routed to the data router.
The data routing circuit determines the output mode of operation from the Address Handler and
registers. When the output mode is set to serial, the outputs get their signals routed from the
Data Register. When the output mode is set to parallel, the outputs get their signal routed from
the rear connector circuit. Notice that, because the rear connector signals are not routed to the
data routing circuit when the primary mode of operation is serial, the output mode of operation
cannot be parallel when the primary mode is set to parallel. For additional descriptions of

Theory of Operation
Chapter 3
The register circuitry section consists of the Data Register, the Module ID Register, the Output
Mode Register, and the Primary Mode Status Register.
The Data Register is a 4-byte serial-in parallel-out shift register. Data is received on the MOSI
line from either Slot 0 or the data acquisition board when SS* is enabled, D*/A indicates data
transfer (D*/A low), and the Data Register address was selected in the Address Handler. When
the output mode of operation is set to serial, the Data Register controls the state of the
SCXI-1163 outputs. Two addresses can access the Data Register–0001 and 0006 (hexadecimal).
Selecting 0001 will set the output mode to serial, and selecting 0006 will return the output mode
to the primary mode. The complete descriptions of the register bits are given in Chapter 4,
1. SS* goes low, enabling communication with the board.
2. Write 0001 or 0006 (hexadecimal) to the Address Handler. This selects the Data Register.
3. D*/A goes low, indicating that the information sent on the MOSI line is data.
4. The serial data is available on MOSI and SPICLK clocks it into the register.
5. SS* goes high and D*/A goes high, indicating an end of communication. This action latches
the Data Register bits.
At reset or at power up, the states of the outputs of the Data Register are set to logic states.
The Module ID Register connects to MISO on the SCXIbus. The Module ID Register is a read-
only 4-byte parallel-in serial-out shift register and an SPI communication adapter. The address
of the Module ID Register is hex 0000. The contents of the Module ID Register are written onto
MISO during the first four bytes of transfer after selecting the Module ID Register in the Address
Handler. Zeros are written to MISO thereafter until the Module ID Register is deselected. The
SCXI-1163 module ID is hex 00000012.
The Output Mode Register is a 1-bit register that determines the output mode of operation. Set it
to serial mode by writing to the Data Register at address 0001; write to address 0006 to return to
the primary mode of operation. You can read the output mode by selecting address 0003, pulling
D*/A low, and reading the value on the MISO line. A logic low indicates that the output mode is
set to parallel, whereas a logic high indicates that the output mode is set to serial.
The Primary Mode Status Register is a read-only register which returns the jumper-configured
primary mode of operation. To read the primary mode, select address 0002, pull D*/A low, and
read the value on the MISO line. A logic low indicates that the primary mode is set to serial,
whereas a logic high indicates that the primary mode is set to parallel.
Optically Isolated Output Channels
The SCXI-1163 consists of eight ports of four optically isolated digital outputs. Each port of
outputs has an isolated connection for the Vcc and ground. The outputs of each port are
referenced to their particular grounds and powered by their particular Vccs; therefore, for any
port of outputs to work, a Vcc and a ground must be connected to that particular port. The Vcc,
ground, and four outputs of one port are isolated from the Vcc, ground, and four outputs of any
other port, and are isolated from the internal circuitry of the module. Vcc should be 5 V
±.5 V above the ground for a given port. Figure 3-5 represents one of the optically isolated

output channels and the Vcc and ground connections. Table 3-2 shows the channel and port
assignments.
These outputs are open-collector outputs with 4.7 kΩ pullups, which can sink 12 mA while
maintaining an output voltage below 0.6 V. The rise time of the outputs is 1 µsec into a 100 pF
load; you can obtain shorter rise times by adding additional pullup resistors between the output
and Vcc for that port.

Register Description
Register Description Format
This register description chapter discusses each of the SCXI-1163 registers and the Slot 0
registers. A detailed bit description of each register is given. The individual register description
gives the type, word size, and bit map of the register, followed by a description of each bit.
The register bit map shows a diagram of the register with the MSB shown on the left (bit 31 for a
32-bit register, bit 15 for a 16-bit register, bit 7 for an 8-bit register), and the LSB shown on the
right (bit 0). A rectangle is used to represent each bit. Each bit is labeled with a name inside its
rectangle. An asterisk (*) after the bit name indicates that the bit is inverted (negative logic).
In many of the registers, several bits are labeled with an X, indicating don't care bits. When you
write to a register, you may set or clear these bits without effect.
SCXI-1163 Registers
The SCXI-1163 has an address handler that chooses one of the following five registers. The
Address Handler is a write-only register that contains the address of the register to be read from
or written to. The Module ID Register is a 4-byte read-only register that contains the Module ID
number of the SCXI-1163. The Data Register is a 32-bit write-only register that controls the
output states on the SCXI-1163. The Status registers are 1-bit registers that indicate the mode of
operation of the module–serial, parallel, or serial override. The Parking Register is a dummy
register located at address FFFF.

Address Handler
You must write to the Address Handler at the beginning of each write to or read from the
SCXI-1163. Write the address of the register of interest to this handler, which in turn enables the
register. This register is two bytes long and contains the address of the register to be read from
or written to. The Address Handler is selected when SS* is asserted low and D*/A indicates an
address transfer (D*/A is high). At this time, the address is shifted in the Address Handler
register, MSB first. Table 4-1 lists the register addresses.

This enables the Address Handler output and selects the appropriate register.
You should select the Parking Register (write address FFFF to the Address Handler) after
communication with one of the other registers. This increases the noise immunity of the module
when the module is in its quiescent state.
After you select the Parking Register, SS* should be released high, which deselects the module
and latches all of the data.
At reset or at power up, the Address Handler content is cleared.

Module ID Register
The Module ID register contains the 4-byte module ID code for the SCXI-1163. This code
number is read on the MISO line whenever the Module ID register is accessed. The bytes appear
least significant byte first. Within each byte, data is sent out MSB first. Additional data
transfers result in all zeros being sent on the MISO line. The Module ID register is reinitialized
to its original value each time the module is deselected, reset, or powered up. The Module ID
Register address is hexadecimal 0000.

Data Register
The Data Register contains 32 bits that control the state of each output of the SCXI-1163.
Whenever the Data Register is selected by the Address Handler, the Data Register shifts in the
data present on the MOSI line, bit 31 first, and then latches the data when deselected. At power
up or at reset, the Data Register contains all logic highs. The Data Register has two addresses–
hexadecimal 0001 and 0006. After a write to address 0001, the Data Register drives the outputs
regardless of the jumper-set primary mode of operation (either serial or parallel). After a write to
address 0006, the Data Register drives the outputs only if the primary mode of operation is set to
serial; if the primary mode is set to parallel, the outputs are driven to the logic levels seen at the
rear connector.

Status Registers
The Status Registers are 1-bit read-only registers that indicate the primary (jumper-set) mode of
operation and the mode of operation currently driving the outputs. The register at address 0002
holds the Primary Mode Status; the register at address 0003 holds the Output Mode Status.
Primary Mode Status Register
A 1 indicates that the primary mode of operation is set for parallel writes, while a 0 indicates that
the primary mode of operation is set for serial writes.
Output Mode Status Register
A 1 indicates that the outputs are being set by the data contents of the data register, while a 0
indicates that the outputs are being set in parallel by the levels seen at the rear connector.

Parking Register
This register is a dummy register that you should select after the end of a read or write operation.
Selecting the Parking Register places the module in a state insensitive to noise and to
electrostatic discharge (ESD), which may corrupt the Data Register content and cause the outputs
to change state.
Select the Parking Register by writing FFFF (hexadecimal) to the Address Handler.

Slot 0 Register Descriptions
Slot 0 has three registers–the FIFO Register, the Hardscan Register, and the Slot-Select Register.
Only the Slot-Select Register is relevant to this module. The Slot-Select Register is a 16-bit
write-only register that determines with which slot the data acquisition board speaks when
SLOT0SEL* is released high. With the SCXI-1001 chassis, the Slot-Select Register also
determines in which chassis the desired slot is. Write to the Slot-Select Register using the
SLOT0SEL* line. Maintain software copies of the Slot-Select Register.
If you are using multiple chassis, it is important to understand the architecture of the Slot-Select
Register. Although each chassis has its own physical Slot-Select Register, all are written to at
the same time. The jumper settings in Slot 0 of a chassis determine with which chassis number
Slot 0 is identified. From the software perspective, only one Slot-Select Register exists in a
system composed of multiple chassis.

Programming
This chapter contains a functional programming description of the SCXI-1163 and Slot 0.
Note: If you plan to use a programming software package such as NI-DAQ, LabWindows, or
LabVIEW with your SCXI-1163 board, you do not need to read this chapter.
Programming Considerations
Programming the SCXI-1163 involves writing to the Data Register. Programming the data
acquisition boards involves writes to their registers. See your data acquisition board user manual
for more information. The programming instructions list the sequence of steps to take. The
instructions are language independent; that is, they instruct you to write a value to a given
register without presenting the actual code.
Notation
For the bit patterns to be written, the following symbols are used:
0
1
X
binary zero
binary one
don't care; either zero or one may be written
The bit patterns are presented MSB first, left to right.
Register Writes
This section describes how to write to the Data Register including the procedure for writing to
Table 5-1 lists the rear signal connector pin equivalences to the different National Instruments
only register.
The different bits in this register control independent output channels. There are times when you
may want to set a specific channel or channels without affecting the remaining channels.
However, a write to the Data Register affects all channels simultaneously. You cannot read the
register to determine which channels have been set or reset in the past; therefore, you should
maintain a software copy of the channel states. You can then read the software copy to
determine the status of the channels. To change the state of a single channel without disturbing
the remaining channels, change the bit that controls the channel of interest, set all other bits to
the states last written to them, and rewrite to the Data Register.

Register Selection and Write Procedure
1. Select the slot of the module to be written to. Initial conditions:
SERDATIN = X.
DAQD*/A = 1.
SLOT0SEL* = 1.
SERCLK = 1.
2. Clear SLOT0SEL* to 0. This deasserts all SS* lines to all modules in all chassis.
3. For each bit, starting with the MSB (bit 15), do the following:
a. Set SERDATIN = bit to be sent. These bits are the data that is written to the
Slot-Select Register.
b. Clear SERCLK to 0.
c. Set SERCLK to 1. This rising edge clocks the data. If you are using an MIO-16 board,
writing to the EXTSTROBE* register pulses EXTSTROBE* low and then high,
accomplishing steps 3b and 3c.
4. Set SLOT0SEL* to 1. This asserts the SS* line of the module whose slot number was
written to Slot 0. If you are using multiple chassis, only the appropriate slot in the chassis
whose address corresponds to the written chassis number is automatically selected. When no
communication is taking place between the data acquisition board and any modules, write
zero to the Slot-Select Register to ensure that no accidental writes occur.

5. If you are writing to a Data Register, you must first write address 0001 (hexadecimal) or
for a discussion on the uses of the two addresses. Then follow these steps:
a. Establish the desired SERDATIN level corresponding to this bit.
b. Clear SERCLK to 0.
c. Set SERCLK to 1 (clock the data). If you are using an MIO-16 board, writing to the
EXTSTROBE* register pulses EXTSTROBE* low and then high, accomplishing
steps 5b and 5c.
d. After you have written all the address bits, clear DAQD*/A to 0. This selects the Data
Register, and the data on the MOSI line is written to the Data Register.
6. For each bit to be written to the Data Register:
a. Establish the desired SERDATIN level corresponding to this bit.
b. Clear SERCLK to 0.
c. Set SERCLK to 1 (clock the data). If you are using an MIO-16 board, writing to the
EXTSTROBE* register pulses EXTSTROBE* low and then high, accomplishing
steps 6b and 6c.
d. After clocking the last data bit, if you do not want to write to or read another register,
write hexadecimal address FFFF to the Address Handler to increase the noise immunity
of the module when it is in the quiescent state. This also latches the data into the Data
Register. Selecting another register also latches the data in the Data Register.
7. Pull SLOT0SEL* low to deassert the SS* line and establish conditions for writing a new slot-
select number to the Slot 0 Slot-Select Register.
8. If you are not selecting another slot, write zero to the Slot 0 Slot-Select Register. If you are
selecting another slot, repeat the procedure starting at step 3.

Initialization
The SCXI-1163 powers up with its Data Register set to logic ones and with the output mode of
operation the same as the jumper-set primary mode of operation. If you reset the chassis, the
Data Register resets to logic ones, and the output mode reverts to the primary mode of operation.

Examples
This section describes how to program the SCXI-1163, either alone or in conjunction with other
modules.
The following examples are intended to aid your understanding of module and Slot 0
Example 1
You want to set all the outputs to their logic high state on an SCXI-1163 in Slot 1 of an
SCXI-1000 chassis. The SCXI-1163 is directly cabled to a data acquisition board and has the
primary mode of operation set to serial.
The programming steps are as follows:
11111111 11111111 11111111 11111111to the Data Register of the SCXI-1163 in
Slot 1.
Example 2
An SCXI-1000 chassis has four SCXI-1163 modules in Slots 1, 2, 3, and 4. The SCXI-1163 in
Slot 4 is cabled to the data acquisition board and has the primary mode set to serial. The
SCXI-1163 in Slot 3 is not cabled to a data acquisition board and has the primary mode set to
parallel. You want to set the following channels to their logic low states and leave all the other
channels in their logic high states. The channels of interest in each slot are as follows:
•
•
•
Channel 3 on the SCXI-1163 in Slot 1
Channels 0 through 2 on the SCXI-1163 in Slot 4
Channels 10, 7, 5, and 3 on the SCXI-1163 in Slot 3
The programming steps are as follows:
11111111 11111111 11111111 11110111to the Data Register of the SCXI-1163 in
Slot 1.
11111111 11111111 11111111 11111000 to the Data Register of the SCXI-1163 in
Slot 4.
11111111 11111111 11111011 01010111to the Data Register of the SCXI-1163 in
Slot 3. Since this module is jumpered for a parallel mode of primary operation, the Data
Register must be written to via address 0001(hex) to ensure that the output mode is serial
and therefore that the Data Register drives the outputs.

Example 3
You have a multiple-chassis system with an SCXI-1163 in Slots 4 and 8 of Chassis 1, and
another SCXI-1163 in Slot 11 of Chassis 2. The SCXI-1163 in Slot 8 of Chassis 1 is configured
for a primary mode of operation of parallel, but you have been writing to it in serial by using
address 0001 to access the Data Register. The other two modules have their primary modes of
operation set to serial. You want to do the following:
1. In Chassis 1, Slot 4, set the outputs to their high states on channels 1, 5, and 18, leaving all
other channels in their low states.
2. In Chassis 1, Slot 8, return control of the outputs to parallel control via the rear connector.
3. In Chassis 2, set the outputs to their low states on channels 0 through 7 and on 23, leaving all
other channels in their high states.
Leave all other channels unchanged.
Assuming that the modules are cabled correctly and jumpers W5 and W1 are set correctly, do the
following:
00000000 00000100 00000000 00100010.
0006 and write anything (XXXXXXXX XXXXXXXX XXXXXXXX XXXXXXXX) to the Data
Register. Using address 0006 will return control of the outputs to the rear connector in
parallel, so the pattern written to the Data Register becomes irrelevant.

SCXI-1340 Cable Assembly
The SCXI-1340 cable assembly connects an MIO-16 or DIO-24 board to an SCXI-1163 module.
The SCXI-1340 consists of a mounting bracket at one end and a 50-conductor ribbon cable that
has a 50-pin female connector at the other end. This female connector attaches to the I/O
connector of the data acquisition board. Attached to the mounting bracket is a 50-pin female
mounting bracket connector that connects to the rear signal connector of the module. A male
breakout connector is near the mounting bracket on the ribbon cable. You can use this male
breakout connector to extend the signals of the MIO-16 or DIO-24 board to an SCXI-1180
feedthrough panel or an SCXI-1181 breadboard module. All 50 pins from the MIO-16 or
DIO-24 board go straight to the rear signal connector. You can use a standard 50-pin ribbon
cable in lieu of the SCXI-1340 cable assembly.
The SCXI-1340 has the following advantages over the ribbon cable:
•
•
The SCXI-1340 provides strain relief so that you cannot accidentally disconnect the cable.
The SCXI-1340 includes a mounting bracket that mounts to the chassis so that you can
remove and reinsert the module without explicitly removing the cable from the back of the
chassis. This is especially useful when the SCXI chassis is rack mounted, making rear access
difficult.

The SCXI-1340 has an extra male breakout connector for use with the SCXI-1180
feedthrough panel or additional modules or breadboards that need a direct connection to the
MIO-16 or DIO-24 board.
The SCXI-1340 rear panel gives the module and the chassis both mechanical and electrical
shielding.

SCXI-1340 Installation
Follow these steps to install the SCXI-1340:
1. Make sure that the computer and the SCXI chassis are turned off.
2. Install the SCXI module in the chassis.
3. Plug the mounting bracket connector onto the module rear signal connector (see Figure E-1).
An alignment tab on the bracket enters the upper board guide of the chassis.
4. Screw the mounting bracket to the threaded strips in the rear of the chassis.
5. Connect the loose end of the cable assembly to the MIO-16 or DIO-24 board rear signal
connector.
Check the installation.
After step 1, the order of these steps is not critical; however, it is easier to locate the correct
position for the mounting bracket with a module installed in the chassis. If you are attaching a
cable to the breakout connector, installation is easiest if you attach the second cable before
installing the SCXI-1340.

SCXI-1341 Lab-NB, Lab-PC, or Lab-PC+ and SCXI-1344
Lab-LC Cable Assembly
The SCXI-1341 Lab-NB, Lab-PC, or Lab-PC+ cable assembly connects a Lab-NB, Lab-PC, or
Lab-PC+ board to an SCXI-1163 module. The SCXI-1344 Lab-LC cable assembly connects a
Lab-LC board to an SCXI-1163 module. The SCXI-1341 and SCXI-1344 cable assemblies
consist of two pieces–an adapter board and a 50-conductor ribbon cable that connects the Lab
board to the rear connector of the adapter board. The adapter board converts the signals from the
Lab board I/O connector to a format compatible with the SCXI-1163 rear signal connector pinout
at the front connector of the SCXI-1341 or SCXI-1344. The adapter board also has an additional
male breakout connector that provides the unmodified Lab board signals for use with an
SCXI-1180 feedthrough panel or SCXI-1181 breadboard module. The adapter board gives the
Lab boards full access to the digital control lines. The position of jumper W1 on the SCXI-1341
and SCXI-1344 is irrelevant because the SCXI-1163 does not use jumper W1. Table E-2 lists the
SCXI-1341 and SCXI-1344 pin translations.

DIO-96, AT-MIO-16D, and AT-MIO-64F-5 Board
Connection
To use your SCXI-1163 with a DIO-96, AT-MIO-16D, or AT-MIO-64F-5 board, you need an
NB5 cable. The NB5 cable is a ribbon cable with a 100-pin connector that mates with the data
acquisition board rear signal connector. The other end of the cable is divided into two 50-pin
connectors. Use positions 1 through 50 of the NB5 connector to control the SCXI-1163 and the
SCXIbus via serial communication or to provide parallel inputs to the module. You can either
connect the positions 1 through 50 connector of the NB5 cable directly to the SCXI-1163, or use
an SCXI-1351 between the SCXI-1163 and the NB5 cable. The SCXI-1163 does not use
positions 51 through 100 of the NB5 cable for serial communication; however, you can use those
positions to provide parallel inputs to the module with the DIO-96 and AT-MIO-16D boards.
The SCXI-1351 has the following advantages over the ribbon cable:
•
•
The SCXI-1351 provides strain relief so that you cannot accidentally disconnect the cable.
The SCXI-1351 includes a mounting bracket that mounts to the chassis so that you can
remove and reinsert the module without explicitly removing the cable from the back of the
chassis. This is especially useful when the SCXI chassis is rack mounted, making rear access
difficult.
•
•

or additional modules or breadboards that need a direct connection to the board.

holes in the front panel to hold the SCXI-1302 securely in place.
Check the installation.
SCXI-1351 One-Slot Cable Extender
The SCXI-1351 cable extender is a miniature SCXI-1340 cable assembly. Instead of connecting
to an MIO board 1 m away, the SCXI-1351 female rear connector connects to a male breakout
connector that must be in the rear connector space of the slot to the left. The SCXI-1351 has a
female mounting bracket connector that mates with the rear signal connector of a module, and
also has a male breakout connector on the ribbon cable for connecting to a feedthrough panel or
more cable extenders, or for connection to an NB5 cable for use with a DIO-96 or an
AT-MIO-16D.

SCXI-1351 Installation
Follow these steps to install the SCXI-1351:
1. Make sure that the computer and the SCXI chassis are turned off.
2. Install the SCXI module in the chassis.
3. Connect the rear connector of the cable extender to the breakout connector in the adjacent

Check the installation.
Multiple-Chassis Connections for the SCXI-1163
The SCXI-1163 can operate in a multiple-chassis system with the DIO-24, DIO-96, and the MIO
boards. A multiple-chassis system can consist of up to eight SCXI-1001 chassis controlled by
the same data acquisition board. Notice that you cannot use the SCXI-1000 in a multiple-chassis
system. For each chassis, you need an SCXI-1350 multichassis adapter board and an NB1
ribbon cable.
Note: When connecting multiple chassis, you should use 0.5 m length ribbon cable between
chassis to minimize cable length and maintain signal integrity. However, you can use a
1.0 m cable from the data acquisition board to the first chassis. When you are using the
DIO-96, AT-MIO-16D, or AT-MIO-64F-5, use an NB5 ribbon cable from the data
acquisition board to the first chassis, connecting positions 1 through 50 to the SCXI-1350
in the first chassis.
Installation
After you have installed the data acquisition board into the computer and the SCXI modules into
each of the SCXI-1001 chassis, cable one module from each chassis to the data acquisition board
as follows:
1. Make sure the computer and all the SCXI chassis are turned off.
2. Connect one end of the NB1 (or the 100-pin connector of the NB5) cable to the data
acquisition board.
3. Plug the other end of the cable (positions 1 to 50 of the NB5 cable) into the connector with
latches at the rear of the SCXI-1350 adapter board.

4. Connect another ribbon cable to the chassis extender connector in the middle of the
SCXI-1350.
5. Plug the SCXI-1350 into the back of the SCXI module in the first chassis so that the module
rear connector mates with the front connector on the SCXI-1350. When you are connecting
to an SCXI-1163, be sure to set the jumpers for either a DIO-type or an MIO-type board as
appropriate.
6. Screw the rear panel to the threaded strips in the rear of the chassis.
7. Connect the loose end of the ribbon cable from Step 4 into the rear connector of the second
SCXI-1350 and install the adapter board.
8. Continue until all chassis are connected. You do not need to connect anything to the middle
connector of the SCXI-1350 adapter board in the last chassis.
SCXI-1343 Rear Screw Terminal Adapter
You use the SCXI-1343 universal adapter to adapt custom wiring to the SCXI-1163. The
SCXI-1343 has screw terminals and solder pads for signal connection. A strain relief is on the
outside of the rear panel. Table E-6 shows the SCXI-1343 pin connections.
