I remember the beginning of the serial networking (remember RS232 and RS422/RS485?) transition to ethernet. There were two companies that I recall who specialized in serial-to-ethernet converters. Digi was one. I thought those days were long faded into memory. Imagine my surprise to receive this press release announcing an nee serial device server. I know that devices used in manufacturing have a long lifespan. But, wow, this goes back!
Digi International announced May 19 the Digi Connect EZ 4 TS and Digi Connect EZ 8 TS, next-generation serial device servers designed to help organizations modernize legacy serial infrastructure with enhanced security and centralized management — without requiring enclosure or wiring changes.
The EZ TS family builds on the current Digi Connect EZ platform and provides an efficient transition path for existing ConnectPort TS and PortServer TS deployments, while introducing new capabilities for today’s IT and OT requirements.
Digi expands upon the many devices still in use.
Serial connectivity remains essential across industrial automation, robotics, retail POS, kiosks and embedded systems. However, many deployments lack the security and remote access capabilities required in modern environments. Digi Connect EZ TS enables organizations to securely connect and manage legacy serial devices over IP — without replacing existing equipment.
