Installing the TB-414X
Complete the following steps to install the TB-414X with a PXIe-414
x
and prepare signal
connections.
Before you begin, install the PXIe-414
x
in a chassis and ensure that all signals are
disconnected from the PXIe-414
x
if you have not already done so. Refer to the getting started
guide for your module at
for installation instructions.
Note
Maintaining low leakage performance of the SMU and TB-414X requires
careful selection and termination of the external wiring to ensure guarding of the HI
and HI Sense signals and to minimize negative effects from wiring insulation
materials and contaminants. The SHDB25F-DB25F-LL cable accessory has been
designed with these considerations in mind and utilizes the TB-414X, allowing for
one end to be easily reterminated into an alternate connector, if needed.
Note
NI recommends wearing clean gloves during assembly to avoid
contamination from residues or other debris.
1.
Prepare the wires by stripping the insulation 5 mm to 6 mm (0.197 in. to 0.236 in.) from
one end of all wires.
Use signal wires with a wire gauge of 24 to 18 AWG.
2.
Disassemble the TB-414X.
a)
Unscrew the four screws on the top of the TB-414X to remove the top cover.
b)
Unscrew the two screws securing the strain relief to remove the strain relief.
