Serial to Ethernet Converters
Transmit RS232/422/485 over Ethernet
A Serial to Ethernet Converter connects devices with RS232, RS422, or RS485 serial interfaces to a local area network for transmission of serial data over wired or wireless Ethernet. By converting serial data signals into Ethernet (TCP or UDP) packets, and vice versa, they enable reliable data transmission to other devices or network server applications. This is accomplished by encapsulating the serial data in Ethernet packets in a manner that best fits the type of data being transported.
With a physical wired or wireless (LTE or WiFi) Ethernet network connection on one side, and one or more serial ports on the other side, Serial to Ethernet Converters are designed to ensure that when you access attached devices over a network the connection operates as if you are locally connected to the serial port with a direct cable connection. This is perfect in M2M communication where client access needs to be made independent of any operating system or proprietary protocol. While some Serial to Ethernet Converters can be very simple devices, it is best practice to use one with advanced security functionality, data encryption, and user authentication to ensure network data transmissions, and access to network equipment is protected.
Installing a Serial to Ethernet Converter is ideal if you need to:
- Replace serial cabling with Ethernet but maintain the use of devices that were active on the serial network
- Set-up virtual COM ports to connect PC or Servers to remote serial devices over Ethernet
- Communicate to multiple serial devices at the same time across a network
- Replace existing serial dial-up modem connections
- Manage the serial console port on servers, routers, switches, PBX’s, firewalls, etc... over Ethernet or through out-of-band connections
- Connect serial PLCs or serial signage equipment to Ethernet
IOLAN Serial to Ethernet Converters

Serial to Ethernet Applications
Out-of-Band Console Management
Secure access to USB or RJ45 RS232 console ports on routers, switches, etc, via inband Reverse Telnet / SSL / SSH or out-of-band over integrated LTE, WiFi, or modem for multiple alternate access methods when the network is down. Out-of-Band Management: What is it and why do I need it?
Using RAW TCP Sockets
A raw TCP socket connection which can be initiated from the IOLAN serial to Ethernet converter or from the remote host/server. This can either be on a point-to-point or shared basis where a serial device can be shared amongst multiple devices. TCP sessions can be initiated either from the TCP server application or from the Perle IOLAN serial to Ethernet converter.
Using RAW UDP Sockets
For use with UDP based applications, Perle IOLANs can convert serial data for transport across UDP packets either on a point-to-point basis or shared across multiple devices.
Serial Tunneling between two Serial Devices
Serial Tunneling enables you to establish a link across Ethernet to a serial port on another IOLAN. Both IOLAN serial ports must be configured for Serial Tunneling (typically one serial port is configured as a Tunnel Server and the other serial port as a Tunnel Client).
Create a Virtual COM Port
Serial ports can be connected to network servers or workstations running Perle's TruePort software operating as a virtual COM port. Sessions can be initiated either from the Perle IOLAN or from the TruePort COMport Re-director Utility.
