Request a price
The ATOP SE5201 is a single-port serial device server that puts one RS-232/422/485 device on Ethernet through a 10/100BASE-T(X) RJ45 port. It accepts 5 VDC and 9-30 VDC inputs with power redundancy, carries industrial EMC protection and operates from -40°C to +70°C in a 65 × 78 × 28 mm metal housing. Typical uses are PLCs, HMIs, barcode scanners and shop-floor terminals.

Description
Despite Ethernet having become the new backbone standard of Industrial Automation, Serial devices still remain highly relevant today, with numerous devices installed on sites worldwide. So with ATOP’s SE5201 Series, you can transform any serial device into an Ethernet-capable one, allowing you to control and monitor your legacy serial devices via your LAN or WAN – or even over the internet.
With such connectivity, the amount of time required to configure or troubleshoot a serial device located on a factory floor or in a remote location is eliminated. And with such Ethernet-based connectivity, serial devices can be integrated into modern practices such as Industry 4.0 and IIoT, allowing you to extend their lifetime and avoid wholesale device upgrades in the near future.
Featuring 1 x software-selectable Serial Port and 1 x RJ45 Port, the SE5201 Series is a simple-to-install device, with easy configurations options such as Telnet, Web browser, or other Windows utilities. And using the VirtualCOM software, Windows-based applications can access serial devices by mapping the virtual com ports to the SE5201 serial server series.
Encased in a rugged metal housing offering high EMC protection, the SE5201 Series is ideal for industrial and manufacturing automation applications, such as PLCs, HMIs, Barcode Scanners, Data Terminals, Electronic Kanbans, Shop Floor Control Systems, and Pick-to-Light Systems.

Which version do I need?
This page covers the SE5201 series, which ATOP's brochure lists as two codes: SE5201-DB with a DB9 serial connector and SE5201-TB with a TB5 terminal block. Both have one RS-232/422/485 port and one 10/100 RJ45 port, so pick on the connector your field cabling uses. The SE5201C is the lighter entry version (5 VDC only, semi-industrial EMC); the SE5202 adds a second serial port, an optional 100 Mbps SFP uplink and optional isolation.
Typical applications for the SE5201
- Connecting PLCs and HMIs with serial ports to a plant Ethernet network
- Barcode scanners and data terminals on the factory LAN
- Electronic kanban and shop floor control systems
- Pick-to-light systems
- Remote configuration and troubleshooting of legacy serial devices over LAN or WAN
- Letting Windows applications reach a serial device through a VirtualCOM port

SE5201 — frequently asked questions
What is the difference between the SE5201 and the SE5201C?
Both have one RS-232/422/485 port, one 10/100 RJ45 port, a 65 × 78 × 28 mm housing and a -40°C to +70°C rating. The SE5201 adds a 9-30 VDC input alongside 5 VDC with power redundancy and is ticked for industrial EMC protection; the SE5201C runs from 5 VDC only with semi-industrial EMC protection.
Does the SE5201 convert Modbus TCP to Modbus RTU?
ATOP's selection guide lists serial server modes for the SE5201 (TCP server, TCP client, UDP, VirtualCOM and Reverse Telnet) but no Modbus TCP to RTU/ASCII gateway function. For protocol conversion ATOP lists the MB5201 Modbus gateway, which also has one serial port and one RJ45 port.
What power supply does it need?
It accepts 5 VDC and 9-30 VDC inputs, and ATOP's selection guide ticks power redundancy for this model.
How many network connections can it serve?
In TCP server mode it accepts up to 4 connections; TCP client mode is listed as 1/VCOM and UDP supports 4 ranges. VirtualCOM and Reverse Telnet are also supported.
Can Windows software use it as a COM port?
Yes. ATOP's VirtualCOM software maps a virtual COM port on the Windows PC to the SE5201's serial port, so existing serial applications can reach the device over the network. Configuration is by web browser, Telnet or ATOP's Windows utilities.
When should I choose the SE5202 instead?
Choose the SE5202 when you need two serial ports, a 100 Mbps SFP fibre uplink instead of RJ45, or optional 3 kV serial isolation. It shares the SE5201's power input, EMC and temperature ratings in a 75 × 85 × 28 mm housing.
