Industry data shows that over 65% of industrial equipment still relies on RS232 or RS485 , and in retrofit projects, up…
Many hotel tech upgrades start with a simple promise: “Just add smart switches. It’s easy.” In practice, it rarely is. A 12‑floor hotel built in the 1980s faced the classic problem. Walls were thick, conduits were stuffed with decades of old telephone and coax cable, and no wiring diagram existed. When the property decided to…
Remote Patient Monitoring Is Growing Fast Here’s a number that puts this in context: the global remote patient monitoring market was valued at $50–60 billion in 2024 and is projected to reach $120–150 billion by 2030, growing at a CAGR of 15–18% . According to MarketsandMarkets , the healthcare IoT market exceeded $150 billion in 2024 , driven by aging populations, the shift to…
The Market Shift: Why Cities Are Moving to Wireless Street Lighting Street lighting accounts for 40–50% of municipal energy costs in many cities . According to industry data, the global smart street lighting market was valued at $8–10 billion in 2024 and is projected to grow at a CAGR of 20–25% through 2030 . he main things that make…
A military outpost needs radar data from a hilltop 3 kilometers away. Radio jammers are active. Copper cable is impossible. Fiber is the only option—but the radar speaks RS232. A factory floor has five VFDs running conveyors. Every time a motor starts, RS485 data from nearby temperature sensors turns to garbage. The control room is…
RS485 is the backbone of industrial automation, but when communication drops, troubleshooting can be a nightmare. While it often runs for years without trouble, random timeouts, node dropouts, or corrupted data frames can bring a production line to an expensive halt. When an RS485 network fails, it’s usually due to one of a few common…
When you are adding I/O to an industrial control system you will have to choose between three protocols: EtherNet/IP, PROFINET and Modbus TCP. People usually think it is easy: if you have a Siemens PLC you should use PROFINET. If you have a Rockwell PLC you should use EtherNet/IP. For everything you should use Modbus…
RS485 repeaters do one thing: they take a RS485 signal in and send a clean copy of the RS485 signal out. They work well when the RS485 repeaters are wired correctly. According to maintenance logs from industrial sites, over 80% of repeater-related problems come from installation errors, not defective hardware . The RS485 standard specifies a maximum…
RS485 can handle up to 32 devices on a single pair of wires—If you do the wiring correctly everything will work properly.. If you get it wrong you will waste a lot of time trying to find and fix problems that happen sometimes like messed up data or nothing working at all. The standards for…
You search for “best fiber optic modem” and you get list after list of home gear. Wi-Fi speeds. Mesh coverage. Which router works best with Verizon Fios. If you’re putting a fiber link in a factory, a substation, or a remote monitoring site, those lists are useless. This guide is for industrial users. Here’s what…
