Chapter 2 DAQ System Overview

68-Pin BNC Accessories

You can use your 68-pin cable to connect your DAQ device to the following BNC accessories:

• BNC-2110—Provides BNC connectivity to all analog signals, some digital signals, and

spring terminals for other digital signals

• BNC-2111—Provides BNC connectivity to 16 single-ended analog input signals,

two analog output signals, five DIO/PFI signals, and the external reference voltage for

analog output

• BNC-2120—Similar to the BNC-2110, and also has a built-in function generator,

quadrature encoder, temperature reference, and thermocouple connector

• BNC-2090A, BNC-2090—Desktop/rack-mountable device with 22 BNCs for connecting

analog, digital, and timing signals

• BNC-2115—

(NI 6225/6255 Devices) Provides BNC connectivity to 24 of the differential

(48 single ended) analog input signals on Connector 1 of NI 6225/6255 devices

68-Pin Screw Terminal Accessories

You can use your 68-pin cable to connect your DAQ device to the following screw terminal

accessories:

• SCB-68A, SCB-68—Shielded connector block with temperature sensor

• TB-2706

—Front panel mounted terminal block for PXI/PXI Express M Series devices

• SCC-68—I/O connector block with screw terminals, general breadboard area, bus

terminals, and four expansion slots for SCC signal conditioning modules.

• TBX-68—DIN rail-mountable connector block

• CB-68LP, CB-68LPR—Unshielded connector blocks

RTSI Cables

Use RTSI bus cables to connect timing and synchronization signals among PCI/PCI Express

devices, such as X Series, E Series, CAN, and other measurement, vision, and motion devices.

Since PXI devices use PXI backplane signals for timing and synchronization, no cables are

required.

SCC Carriers and Accessories

SCC provides portable, modular signal conditioning to your DAQ system. Use your 68-pin cable

to connect your device/module to an SCC module carrier, such as the following:

• SCC-68—68-pin terminal block with SCC expansion slots

• SC-2345—Shielded carrier for up to 20 SCC modules

• SC-2350—Shielded SCC carrier for TEDS sensors

TB-2706 uses Connector 0 of your PXI/PXI Express module, therefore does not require a cable. After a

TB-2706 is installed, Connector 1 cannot be used.
