PDF Content Summary: INSTALLATION INSTRUCTIONS NI SCB-264X Shielded Connector Block for the NI PXI-2532
̭ Ρ ̈́νιϋΠ͉ͅȂ඾ུࢊβȜΐ͜܄̞̳ͦ̀͘͘ȃ This document describes how to install and connect signals to the National Instruments SCB-264X shielded connector block. Use the NI SCB-264X to interface individual signal wires to the rows and columns of the NI PXI-2532 matrix. The NI SCB-264X has five ribbon cable connectors for connecting to the NI TB-2640/2641/2642/2643/2644 (NI TB-264X) connector blocks and screw terminals for connecting signals. The NI SCB-264X supports all NI PXI-2532 topologies that are configured with the NI TB-264X. The NI SCB-264X can be used alone, or it can be rack-mounted using the included DIN rail-mounting kit. Note References to the NI TB-264X in this document do not include the NI TB-2645. The NI TB-2645 is not compatible with the NI SCB-264X. Refer to the NI Switches Getting Started Guide to determine when to install the NI SCB-264X. Visit ni.com/switches for information about other switching solutions.

Install the DIN-Rail Mounting Bracket (Optional) If you prefer DIN-rail mounting instead of stand-alone operation, the NI SCB-264X is packaged with an optional DIN-rail mounting bracket. The bracket can be installed horizontally or vertically to the bottom of the NI SCB-264X. To install the mounting bracket, align the bracket with the appropriate horizontal or vertical holes, and secure the bracket to the NI SCB-264X using the two included screws. 4. Connect the NI SCB-264X to the NI TB-264X The NI TB-264X connects to and configures the NI PXI-2532 switch module into different topologies. To use the NI SCB-264X, you must connect to the NI PXI-2532 through one of the NI TB-264X terminal block accessories listed in Table 1. To connect the NI SCB-264X to the NI TB-264X, refer to Figures 1 and 2 while completing the following steps: 1. Gather the ribbon cables required for connecting the NI SCB-264X to the NI TB-264X. Depending on which NI TB-264X you are using, you may have up to four column cables (34-conductor ribbon cables with 2 × 17 connectors) and one row cable (16-conductor ribbon cable with a 2 × 8 connector). Refer to the installation instructions for your NI TB-264X for more information about the required cables. 2. Follow the steps in the NI TB-264X installation instructions to connect the ribbon cables to the NI TB-264X. Note the location of each cable in the NI TB-264X. Specifically, note whether the cable is connected to the J2 or J3 connector and whether it is connected to the lower or upper column connection board. 3. To access the ribbon cable connectors on the NI SCB-264X, insert a 1/8 in. flathead screwdriver into the groove on the edge of the NI SCB-264X. 4. Carefully turn the screwdriver counterclockwise until the top cover of the NI SCB-264X unsnaps. 5. Remove the top cover. 6. Inside the NI SCB-264X there are two strain-relief bars. Loosen the strain-relief screws on the strain-relief bar closest to the ribbon cable connectors. 7. Route the ribbon cables through the strain-relief opening. NI SCB-264X Installation Instructions 4 ni.com 8. Attach the ribbon cables to the column and row ribbon cable connectors. To secure the cables, ensure that the locking mechanism engages. Note The installation location of each cable must be consistent with the connections made inside the NI TB-264X. Use the designators on the NI SCB-264X printed circuit board to ensure the correct location of each cable. LOWER J2 and LOWER J3 refer to the J2 and J3 connectors on the lower column connection board of the NI TB-264X; UPPER J2 and UPPER J3 refer to the J2 and J3 connectors on the upper column connection board of the NI TB-264X. If these connections are incorrect, Tables 2 through 10 are invalid. 9. To connect signal wires to the NI SCB-264X, refer to step 5. Connect Signals. Otherwise, replace the top cover, and refer to step 6. Connect the NI TB-264X to the NI PXI-2532. 13 2

Connect Signals To connect signals to the NI SCB-264X, refer to Figures 1 and 2 while completing the following steps: 1. Prepare the signal wire by stripping the insulation no more than 7 mm from the end of the wire. 2. Loosen the strain-relief screws on the strain-relief bar closest to the screw terminals. 3. Route the signal wires through the strain-relief opening. 4. Based on the NI TB-264X you are using, refer to the appropriate table (Tables 2 through 10) to determine which screw terminal to connect the signal wire. 5. Insert the stripped end of the wire fully into the terminal. Secure the wire by tightening the screw of the terminal. Caution No bare wire should extend past the screw terminal. Exposed wire increases the risk of a short-circuit causing a failure. 6. Connect the protective earth (PE) ground to a safety ground lug. 7. Tighten the screws on the strain-relief assemblies to secure the cables. 8. Replace the top cover. Note As illustrated in Figure 2, the NI SCB-264X contains six unused screw terminals, Node 1 and Node 2, that you can use to assist in your signal/ground connections. Node 1 consists of two screw terminals that are connected to each other but are not connected to any other screw terminals; Node 2 consists of four screw terminals that are connected to each other but are not connected to any other screw terminals. Node 1 and Node 2 are not connected together. Use of the node terminals is optional. Tables 2 through 8 illustrate the wiring configurations available for the NI SCB-264X. © National Instruments Corporation 7 NI SCB-264X Installation Instructions
