Overview

USB-503-RJ45 is a converter that converts from USB to RS485. It is an isolated type that can be used safely even for use in the factory environment.
It is a general specification and can be used for a wide range of applications.
RS485 is equipped with RJ45 connectors used for LANs, and commercially available LAN cable can be used as communication cables, so the work of wiring steps can be reduced.
