Industrial Serial Server

The Brainboxes ES-522 is a two-port device server that connects serial equipment to an Ethernet network. It suits automation engineers and system integrators who need reliable serial-to-IP conversion for monitoring or control applications. First listed by the manufacturer in 2019, it carries the model number 522 and is supplied in new condition.

Fit for Purpose

This unit fits projects that require exactly two serial ports bridged to a LAN. It is not for installations needing more than two ports, Power over Ethernet, Wi-Fi connectivity, or integrated I/O beyond simple serial tunnelling. Buyers who need a different port count or wireless uplinks should look at alternative hardware.

Deciding Specification

The defining detail is the dual serial-port count combined with wired Ethernet bridging. If your design calls for precisely two serial connections over a standard network cable, this model matches that requirement; otherwise a different port density or interface will be necessary.
