Using BNCs
You can connect BNC cables to your DAQ device using BNC accessories
such as the BNC-2110, BNC-2120, and BNC-2090A. To connect your
DAQ device to a BNC accessory, use one of the following cables:
• SH68-68-EPM—shielded cable
• SH68-68R1-EP—shielded cable with one right angle connector
• SH6868—shielded 68-conductor cable
• RC68-68—unshielded cable
Using Screw Terminals
You can connect signals to your DAQ device using a screw terminal
accessory such as:
• CB-68LP, CB-68LPR—low-cost screw terminal block
• SCB-68—shielded screw terminal block with breadboard areas
• TBX-68—DIN rail mountable screw terminal block
To connect your DAQ device to a screw terminal accessory, use one of the
following cables:
• SH68-68-EPM—shielded cable
• SH68-68R1-EP—shielded cable with one right angle connector
• RC68-68—unshielded cable
Using SSR or ER Digital Signal Conditioning
SSR and ER series provide per channel digital signal conditioning.
Custom Cabling/Connectors Options
The CA-1000 is a versatile connector/enclosure system. It allows the user
to define I/O connectors on a per-channel basis. Internally, the system
allows for flexible custom wiring configuration.
If you want to develop your own cable, follow these guidelines for best
results:
• Use shielded twisted-pair wires for each differential AI pair. Connect
the shield for each signal pair to the ground reference at the source.
• Route the analog lines separately from the digital lines.
• When using a cable shield, use separate shields for the analog and
digital halves of the cable. Failure to do so results in noise coupling
into the analog signals from transient digital signals.
