Let's face it - the data communication ports of all computers and most intelligent field devices were designed for the office and not industry. You may not even suspect some of the problems this can cause, but they include :

• burned comm ports - and even hard disks and video cards too!
• random system reboots
• applications hanging or crashing which cannot be duplicated in the lab
• intermittent data comm failures
• frequent site visits with spiraling labor and transportation costs
• waning customer confidence in your products and expertise
  

The main culprit is the office-grade assumption that all grounds are the same, so ground loops are Ok. Plus your RS-232 ground wire acts as a big antenna to bring in all kinds of noise and surges in to affect your hard disk and CPU.

Full galvanic isolation protects your computer, your scope of supply, your work schedule, and your reputation. So don't install another system until you talk to us. Our expertise on grounding, surge, and robustness in RS-232, RS-422, RS-485 and fiber optics will make your data flow like water ... safely, silently, and sanely.
