In our experience across hundreds of factory retrofits, more than 65% of industrial equipment still uses RS232 or RS485. But in retrofit projects, up to 60% of the time, structural problems make it impossible to run new cable. Your factory has a PLC on the floor, a power meter hidden away in an electrical room,…
The Reality: 30% of Industrial Retrofits Face a Cable Problem According to Astute Analytica , the global serial device server market was valued at $323 million in 2024 and is projected to reach $476 million by 2033, growing at 4.75% annually . Industry data shows that over 65% of industrial equipment still relies on RS232 or RS485 , and in retrofit projects, up…
You have two RS485 devices, maybe a PLC in one building and a remote sensor in another, separated by a few hundred meters. The cost and complexity of new cable trenching is prohibitive, and complicated IT networks are a headache you don’t need. You just want a reliable, transparent data link. This is exactly where…
You deployed a wireless bridge to replace that final, impossible mile of RS485 cable to your solar string inverters. The theory was simple. But now, the connection drops randomly, Modbus data is garbled, or the bridge mysteriously reboots every day at dawn. Solar sites are brutal environments. Wide temperature swings, electromagnetic interference (EMI) from humming…

Why Remote Electric Meter Monitoring Matters The global smart electric meter market was valued at $20–25 billion in 2024 and is projected to grow at a CAGR of 8–10% through 2030 . A key driver is the need for real‑time energy data in commercial buildings, factories, and utility networks—data that traditionally required manual meter reading or dedicated wiring. According to industry…
