USR-DR13X User Manual
1. Introduction
1.1. Overview
USR-DR13X is an ultra-small DIN rail mounting industrial-grade serial device server launched by PUSR. It can
realize two-way fast data transmission between RS232/RS485 and RJ45 Ethernet port. It integrates TCP/IP
protocol stack internally and Modbus gateway function. It can be directly integrated into industry scenarios, thus
quickly completing business framework construction and saving human resources investment.
This series of products support wide voltage power supply with terminal blocks connector, come with
RS232/RS485 serial port, support baud rate 600~230400bps, high and low temperature resistance, can be 7×24H
stable operation, no fear of any harsh environment.This series of products have been strictly tested by the market
for many years, and have been recognized by users in many industries such as finance, transportation, large
company networks, factory manufacturing, etc. and widely used in their own project solutions.
