The manufacturer part number National Instruments uses for this mating connector is as follows: • ERNI Components, Inc.
Chapter 2 Configuration and Installation This chapter describes the SCXI-1163 jumper configurations, installation of the SCXI-1163 into the SCXI chassis, signal connections to the SCXI-1163, and cable wiring. Module Configuration The SCXI-1163 module consists of five user-configurable jumpers and one reserved jumper as shown in the parts locator diagram, Figure 2-1.
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.
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.
Chapter 2 Configuration and Installation - 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.
Configuration and Installation 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.

Configuration and Installation Chapter 2 Rear Signal Connector Signal Descriptions, Serial Configuration Pin Signal Name Description 24 or 50 DIG GND Digital Ground – Supplies the reference for data acquisition board digital signals and is tied to the module digital ground. Pin 50 is for DIO-type boards. Pin 24 is for MIO-type boards. Jumper W3 selects the pin. 25 SERDATIN Serial Data In – Taps into the SCXIbus MOSI line to provide serial input data to a module or Slot 0.
Chapter 2 Configuration and Installation All other pins are not connected. 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.
Configuration and Installation Chapter 2 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.
Chapter 2 Configuration and Installation 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.
Configuration and Installation Chapter 2 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.
Chapter 2 Configuration and Installation To write to the Address Handler, follow these steps: 1. Initial conditions: SS* asserted low. SERDATIN = don't care. DAQD*/A = 1 (indicates data will be written to the Address Handler). SLOT0SEL* = 1. SERCLK = 1 (and has not transitioned since SS* went low). 2. For each bit to be written, and starting with the MSB, perform the following actions (these bits are the address of the register of interest): Establish the desired SERDATIN level corresponding to this bit.
Configuration and Installation Chapter 2 To write to the Data Register, follow these steps: 1. Initial conditions: SS* asserted low. SERDATIN = don't care. DAQD*/A = 0 (indicates data will be written to a Register). SLOT0SEL* = 1. SERCLK = 1 (and has not transitioned since DAQD*/A went low). 2. For each bit to be written: Establish the desired SERDATIN level corresponding to this bit. SERCLK = 0. SERCLK = 1. This rising edge clocks the data. 3. Pull DAQD*/A high.
Chapter 2 Configuration and Installation To read from the Module ID Register, follow these steps: 1. Initial conditions: SS* asserted low. SERDATIN = don't care. DAQD*/A = 0. = 1. SERCLK = 1 (and has not changed since DAQD*/A went low). 2. For each bit to be read: SERCLK = 0. SERCLK = 1. This rising edge clocks the data. Read the level of the SERDATOUT line. 3. Pull DAQD*/A high. This disables further reads from the Module ID Register.
Configuration and Installation Chapter 2 To read from a Status Register, follow these steps: 1. Initial conditions: SS* asserted low. SERDATIN = don't care. DAQD*/A = 0. = 1. SERCLK = don't care. 2. The Status Registers are 1-bit read-only registers that indicate the primary or 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.
Chapter 3 Theory of Operation This chapter contains a functional overview of the SCXI-1163 module and explains the operation of each functional unit making up the SCXI-1163. Functional Overview The block diagram in Figure 3-1 shows the key functional components of the SCXI-1163.

SCXIbus Equivalents for Rear Signal Connector Rear Signal Connector Signal SCXIbus Equivalent SERDATIN DAQD*/A SLOT0SEL* SERCLK SERDATOUT MOSI D*/A INTR* SPICLK MISO 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.
Chapter 3 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 jumperconfigured primary operating mode. When the primary operating mode is serial, the signals from the rear connector are routed to the SCXI digital interface.
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.
Chapter 3 Theory of Operation 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. TTL Input from SCXI-1163 Data Register VCC 4.
Chapter 4 Register Descriptions This chapter describes in detail the SCXI-1163 Address Handler, the Module ID Register, the Data Register, the Status registers, and the SCXI-1000/1001 Slot 0 registers. 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.
Register Descriptions Chapter 4 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).
Chapter 4 Register Descriptions 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.
Register Descriptions Chapter 4 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.
Chapter 4 Register Descriptions 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.
Register Descriptions Chapter 4 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.
Chapter 4 Register Descriptions 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.
Register Descriptions Chapter 4 Slot-Select Register The Slot-Select Register contains 16 bits that determine which module in which chassis is enabled for communication when the SLOT0SEL* line is high. An SCXI-1000 chassis selects the appropriate module in its chassis, regardless of the chassis number written. The Slot-Select Register shifts in the data present on the MOSI line, bit 15 first, when SLOT0SEL* is low.
Chapter 5 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.

Chapter 5 Programming 5. If you are writing to a Data Register, you must first write address 0001 (hexadecimal) or address 0006 (hexadecimal) to the Address Handler. See Chapter 4, Register Descriptions, 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).
Programming Chapter 5 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 programming. It will be helpful to refer to the bit descriptions for the Data Register, Status Register, and Address Handler in Chapter 4, Register Descriptions. 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.
Chapter 5 Programming 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.
