In modern network installations, speed alone isn't enough—precision is what keeps systems reliable and downtime low. Tools like the WireXpert MP cable certifier reflect how far copper cable diagnostics have evolved, moving beyond simple pass-or-fail testing into actionable insight. By running a full 500 MHz sweep on a Category 6A link, technicians can instantly verify performance while simultaneously collecting detailed diagnostic data. When issues like crosstalk appear, the real advantage is visibility: the tester pinpoints not just that a problem exists, but exactly where along the cable it occurs. Instead of replacing an entire run or guessing at weak terminations, installers can focus on a specific jack and even the exact wire pairs causing interference. This kind of targeted troubleshooting saves time, materials, and frustration on the job site. Ultimately, smart diagnostic tools turn cable certification from a reactive chore into a proactive way to build and maintain better networks.

The tester pinpoints not just that a problem exists, but exactly where along the cable it occurs.

Okay, let's look at the diagnostic tools on the WireXpert MP cable certifier. These are the tools that help tell you where the problem is on the cable. I've got the certification tester set up on a longer link here. Let's go ahead and test. You can see I'm set up for category 6A. I'm gonna go ahead and start this test. Super fast test even with the diagnostic information turned on. There we go. That's a full five hundred megahertz sweep. Now this cable is wired correctly, five sixty eight b, but I've got a problem with crosstalk showing us that that's not okay, but we can use this function to actually dig in to the exact build of the cable. It's telling us along this thirty meter long cable exactly where the crosstalk is the worst. So in this situation, the highest peak is right there at two meters in. So it's my near jack that is giving us the problem. It has the most crossed off and it's even telling us which particular pairs are the offenders here. So if I want to make this cable better instead of yanking the whole cable out, instead of guessing which termination is the weakest, I'm gonna go directly to the near termination and I'm gonna go directly to that one, two, seven, eight pair combination and I'm gonna clean those up. That's a powerful tool for technicians to fix cable on the fly telling them exactly where the problems are in copper cabling links. This is the WireXpert MP and this is our next locator option on the WireXpert MP certifier.

Case's N Series small dozers keep the same engines and rebuild the cab

Case Construction Equipment's 650N, 750N and 850N dozers keep the same engine, with updates focused on cab controls, display and customization.

  • 01With the engine unchanged, the M-to-N story is cab controls, operator profiles and improved sightlines.
  • 02With the 650N now on electric-over-hydraulic blade control, Case says its entire dozer lineup uses EH blade control.

Data centers and advanced factories now compete for the same crews, DPR says

DPR Construction's fourth-quarter 2026 analysis finds AI data centers and advanced manufacturing plants now need the same power, planning, workforce and prefabrication.

  • 01Factory schedules can shift as data centers draw the same electricians, mechanical trades and commissioning specialists.

HCSS Fleet now pulls engine hours, miles and fuel straight from Motive

HCSS Fleet now pulls engine hours, miles and fuel straight from Motive

HCSS Fleet now pulls engine hours, odometer readings and fuel use straight from Motive, so crews no longer have to key them in by hand. Motive-equipped vehicles and assets also appear on the same map as OEM-connected and HCSS-tracked equipment.

  • 01Engine hours, odometer readings and fuel use from Motive-equipped assets now arrive in HCSS Fleet automatically, delivering hours, miles and preventive maintenance triggers without manual entry.
  • 02How much a contractor gains depends on fleet mix: the more units carrying Motive, the more of the fleet map fills in without anyone typing.
  • 03The question for equipment managers now is which telematics source each asset should report through, because HCSS Fleet takes in OEM, HCSS and Motive data side by side.
