Product Introduction & Supply Chain Strategy
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.
The National Instruments BNC-2110 is a shielded connector block designed to simplify signal connections to NI multifunction DAQ cards via standard BNC cabling. Sourcing this unit as New Surplus provides a strategic supply chain advantage for test labs and automated test equipment (ATE) setups requiring noise immunity. Buying genuine New Surplus guarantees optimal shield continuity and eliminates signal cross-talk risks common in worn or refurbished units with loose BNC bayonets, while skipping standard OEM lead-time delays.
Installation & Configuration Guide
1.Pre-Installation (Prep & Safety):Disconnect power and verify ESD protection.
Shut down the host PC or PXI chassis hosting the target DAQ board. Put on an ESD-grounded wrist strap before handling the connector block. Inspect the 68-pin port for bent or contaminated pin receivers.
2.Cable Hookup:Connect primary 68-pin cable.
Connect an SH68-68-EEP or compatible 68-pin shielded cable between the NI DAQ card and the 68-pin connector on the BNC-2110. Tighten thumbscrews hand-tight to ensure complete ground shell shield termination.
3.Configuration & Wiring:Configure signal modes and BNC connections.
Set internal DIP/slide switches or jumper block states (FS/GS for Floating/Ground-Referenced sources) to match your sensor configuration (DIFF vs. RSE/NRSE). Attach coaxial BNC cables from transducers or signal sources directly to designated BNC ports.
4.Power-On & Verification:Verify device identification in software.
Power on the host system. Open NI Measurement & Automation Explorer (MAX) or NI-DAQmx drivers to verify device detection and run a self-test diagnostic. Run an initial test panel loopback to verify noise floors and signal fidelity.

Firmware/Software Versions & Upgrade Notes
- Driver Compatibility: The BNC-2110 is a passive signal routing accessory that works seamlessly with NI-DAQmx driver packages across Windows and Linux environments.
- Pinout Alignment: Ensure your connected DAQ device (e.g., PCIe-6363, PXIe-6361, USB-6363) supports the standard 68-pin M Series or X Series pinout mapped by the BNC-2110.
- Signal Isolation: The BNC-2110 provides shielding against ambient EMI/RFI, but does not contain active galvanic isolation. Ensure input signal voltages remain strictly within the target DAQ board’s rated common-mode limits (typically ±10 V).
Frequently Asked Questions (FAQ)
Q: Is this NI truly brand new, or is it a pulled/refurbished unit?
A: This product is 100% Genuine New Surplus. It has never been deployed in an active test rack or industrial laboratory. We maintain a zero-tolerance policy for second-hand or refurbished stock, ensuring pristine connector contact plating and full structural integrity.
Q: Why is New Surplus a better investment than refurbished signal blocks?
A: Refurbished connector blocks frequently suffer from oxidized solder joints, intermittent BNC spring contact tension, and compromised grounding shields. Purchasing New Surplus guarantees factory-grade shielding and zero channel cross-talk, preventing costly measurement errors in high-precision test applications.
Q: Does the require an external power supply?
A: No. The operates as a passive shielded breakout interface and derives any necessary reference or pull-up signals directly from the connected NI DAQ card via the 68-pin cable.
Q: Can I use both the BNC terminals and the internal screw terminals simultaneously?
A: Yes, provided they route to different signals. The screw terminals give direct access to extra digital lines and custom breadboard nodes not directly pinned out to the primary BNC connectors on the enclosure exterior.
Q: What warranty coverage is included with this connector block?
A: Every NI New Surplus unit is backed by a comprehensive 1-year functional replacement warranty. Each unit undergoes full mechanical and continuity inspection prior to dispatch.
