Introduction

The NI TB-2630B terminal block installs in front of the NI PXI-2530B switch module. The
NI TB-2630B has ribbon cable headers to connect signals to the switch. Screw terminals for the trigger
input and trigger output signals are also available. The NI TB-2630B is designed for use with the
NI PXI-2530B and is not compatible with the NI PXI-2530.

1. Unpack the Terminal Block

To avoid damage when you handle the terminal block, take the following precautions:

Caution Never touch the exposed pins of connectors.

• Ground yourself using a grounding strap or by touching a grounded object.

• Touch the antistatic package to a metal part of the chassis before you remove the terminal block
from the package.

Remove the terminal block from the package and inspect the terminal block for loose components or
any sign of damage. Notify NI if the terminal block appears damaged in any way. Do not install a
damaged terminal block on a switch module.

Store the terminal block in the antistatic package when not in use.

2. Verify the Components

Make sure you have the following:

❑ NI TB-2630B terminal block

❑ PXI chassis

❑ NI PXI-2530B switch module

❑ 1/8 in. flathead screwdriver

❑ Eight 2 × 9, 0.100 in. pitch ribbon cable connectors (included)

❑ 18-conductor, 28 AWG, 0.050 in. pitch ribbon cable (not included)

3. Connect Signals

Caution To ensure the specified EMC performance, operate this product only with shielded cables

and accessories.

To connect signals to the terminal block, complete the following steps:

1. Remove the terminal block top cover screws with the flathead screwdriver.

2. Gently lift the terminal block top cover off the terminal block.

3. Loosen the two screws on the strain-relief assembly and remove the top strain-relief bar.

4. Prepare your ribbon cable by installing the 2 × 9 ribbon cable connectors onto separate
18-conductor ribbon cables.

5. Connect each ribbon cable to a header.

6. Connect the shield of the ribbon cable to the safety ground lug shown in Figure 1.

7. Replace the strain-relief bar and tighten the two screws on the strain-relief assembly to secure the
cables.

8. Replace the terminal block top cover.

9. Secure the terminal block top cover with the top cover screws.

0.100 in. 0.050 in.

When a double row ribbon cable connector is used, the pitch of the ribbon cable is half the pitch of the
connector. For example, a 0.050 in. pitch ribbon cable uses a 0.100 in. pitch connector. Ribbon cable
connector assemblies are typically defined by the pitch of the connector. Refer to Figure 4 for a diagram
of a 0.100 in. pitch cable assembly with a 0.100 in. pitch connector and a 0.050 in. pitch ribbon cable.

The NI TB-2630B includes eight 2 × 9 0.100 in. pitch ribbon cable connectors. Refer to Table 4 for
additional connectors that you can use with the NI TB-2630B.

Figure 4. 0.100 in. Pitch Cable Assembly

You can use any 0.050 in. pitch ribbon cable with the NI TB-2630B. To use a ribbon cable with more
than 18 conductors, remove the unwanted conductors before using. Refer to Table 4 for more
information about the cable connector assembly.
