StarTech.com Industrial RS232 to RS422/485 Serial Port Converter with 15KV ESD Protection

Product Overview

AI-generated summary

StarTech’s Industrial RS232 to RS422/485 converter is a sensible little “fix the wiring” box if you’ve got legacy RS-232 gear and you need to move it onto longer-distance RS-422/485 runs. At ~£62 ex-VAT, it’s priced like a practical tool rather than a mission-critical controller, and that’s exactly how I’d use it: for point-to-point or small device networks where you want more noise immunity and better reach than plain RS-232. The 15KV ESD angle is also genuinely useful in UK industrial environments (plant floors, control cabinets, occasional wiring gremlins) because serial ports are often the first victim when the install gets messy.

That said, I wouldn’t buy this if you’re expecting it to behave like a full-on industrial comms gateway or if you’re building a complex multi-drop RS-485 system with lots of nodes and tricky bus termination requirements—you still need to get the RS-485 side right (termination, biasing, cabling, addressing, baud rate consistency). Also, if your real issue is protocol/application-level incompatibility rather than the electrical layer (RS-232 vs RS-422/485), this won’t magically solve it. Overall: good value for an engineer/sysadmin who just needs reliable electrical conversion for industrial serial, not a “network adapter replacement” for modern Ethernet workflows.
