Product information

Description

The StarTech.com 4-Port Serial to Ethernet Adapter (I43-SERIAL-ETHERNET) enables remote access and management of RS232 serial devices over an IP network. Housed in a full metal enclosure with wall and DIN-rail mounting hardware, the unit measures 178 x 59.4 x 23 mm and supports IEEE 802.3 Ethernet connectivity and multiple serial-to-IP protocols.

Advantages

This 4-port DB9 to Ethernet adapter provides centralized serial device management via Windows Virtual COM Port software or a platform-independent Web User Interface. It supports Telnet Server (RFC2217), TCP Server, TCP Client and UDP protocols, offers dual power input options (DC jack and terminal block), includes ESD level 4 surge protection, and can supply 5 VDC on pin 9 when required. The compact metal chassis and included mounting hardware allow flexible installation in industrial environments.

Suitable for

  • Remote management of RS232 devices such as PLCs, barcode scanners and meters
  • Industrial and factory automation requiring reliable serial-to-IP connectivity
  • Networked serial device deployments on walls or DIN rails
  • Environments needing ESD protection and a rugged metal enclosure

Key specifications

  • Model: I43-SERIAL-ETHERNET
  • Serial ports: 4 x RS232 (DB9)
  • Ethernet: 1 x RJ45 10/100 Mbps (IEEE 802.3)
  • Protocols: Telnet Server (RFC2217), TCP Server, TCP Client, UDP
  • Power input: 100–240 V (adapter included); outputs 5 VDC (can supply 5V on pin 9)
  • Surge/ESD: ESD level 4 protection
  • Dimensions: 178 x 59.4 x 23 mm
  • Mounting: Wall and DIN rail included

How to use

Install the adapter in the chosen orientation using the supplied wall or DIN-rail hardware. Connect RS232 devices to the DB9 ports and link the adapter to the network via the RJ45 Ethernet port. Power the unit using the included universal adapter or the terminal block input. Configure device servers using the Windows Virtual COM Port software to create virtual COM ports on Windows systems or use the Web User Interface from any operating system to set up network parameters and serial-port behavior.

Usage recommendations

For stable operation in industrial settings, mount the adapter on a secure surface or DIN rail, ensure proper grounding, and verify network and serial baud rate settings match connected devices. Use the WebUI for cross-platform configuration and the Windows software for centralized management if deploying multiple units.
