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. 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.

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 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.

SCXI-1163 User Manual 2-4 © National Instruments Corporation

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.

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 kΩ pullup resistor to the SERDATOUT line. This is the factorydefault 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 factorydefault setting is position DIO.

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. 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.

The terminal block kit is listed in the Optional Equipment section in Chapter 1, Introduction.

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 labeling as indicated in Figure 2-3, SCXI-1326 Parts Locator Diagram.

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.

Configuration and Installation Chapter 2

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.

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.

9. Connect the terminal block to the SCXI-1163 front connector as explained in the SCXI-1326

Installation section, the next section in this chapter.

Figure 2-3 shows a parts locator diagram for the SCXI-1326 terminal block.

Warning: 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

Configuration and Installation Chapter 2

SCXI-1326 Installation To connect the terminal block to the SCXI-1163 front connector, follow these steps:

1. Connect the SCXI-1163 front connector to its mating connector on the terminal block.

2. Make sure that the SCXI-1163 top and bottom thumbscrews do not obstruct the rear panel of the terminal block.

3. Tighten the top and bottom screws on the back of the terminal block to hold the terminal block securely in place.

Rear Signal Connector

Note: If you will be using the SCXI-1163 with a National Instruments data acquisition board

and cable assembly, you do not need to read the remainder of this chapter. If you will also be using the SCXI-1180 feedthrough panel or the SCXI-1343 rear screw terminal adapter with the SCXI-1163, you should read this section.

The rear signal connector is configured based on the jumper settings described earlier in this chapter. Jumper W6 determines whether the rear connector will be used for serial or parallel communication. If you set jumper W6 to serial, jumpers W2, W3, and W5 determine whether the rear connector is configured for an MIO-type connection or a DIO-type connection.

Figure 2-4A shows the pin assignments for the SCXI-1163 rear signal connector configured for serial communication. Figure 2-4B shows the pin assignments for the rear signal connector configured for parallel communication.
