This installation guide describes how to install and connect signals to
the TB-2705 terminal block for use with PXI E Series and waveform
generation devices.
The TB-2705 is a terminal block assembly consisting of a printed circuit
board, 62 screw terminals, and a plastic enclosure with a strain relief. The
terminal block assembly connects directly to the front panel of National
Instruments E Series and waveform generation devices, eliminating the
need for an external cable.
The TB-2705 allows you to easily connect analog input, analog output,
counter-timer, and digital I/O signals to your National Instruments device.
The 62 screw terminals allow access to every pin on the device with the
exception of some digital ground signals that are common to one another.
The TB-2705 also has a shielded strain-relief to secure your I/O wires and
provide an adequate chassis-ground connection.
You need the following to set up and use your terminal block:
