RS232 to Ethernet
Transmit RS232 data over Ethernet
RS232 to Ethernet Converters connect devices with RS232 serial interfaces to a local area network for transmission of serial data over wired or wireless Ethernet. By converting RS232 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 RS232 data in Ethernet packets in a manner that best fits the type of data being transported.
RS232 to Ethernet Converters have a physical wired or wireless (LTE or WiFi) network connection on one side, and one or more RS232 serial ports on the other side. They are designed to ensure that when you access attached devices over a network the connection operates as if you are locally connected to the RS232 port with a direct cable connection. This is perfect for M2M communication where client access needs to be made independent of any operating system or proprietary protocol. While some RS232 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.

RS232 to Ethernet Converter Applications
Installing a RS232 to Ethernet Converter is ideal if you need to:
- Replace RS232 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
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.
Remove dial-up modems and instead connect to remote serial equipment across an Ethernet network while still using the AT command set. Learn more about IOLAN Vmodem technology.
Connect Electronic Variable Message Signs
Transmit data from video surveillance technology, pavement sensors, and variable message signs to traffic operation centers.
Factory Floor Automation
Utilize the TCP Socket multi-host capability on IOLAN Device Servers to enable one workstation to simultaneously transmit data to multiple factory machines.
Transmit GPS data
Custom Packet Forwarding allows the user to define the packet forwarding rules based on the packet definition or the frame definition.

More About RS232
RS232 vs EIA232 vs EIA/TIA232
Originally called RS232, the standard was developed in the 1960's to specify the electrical signalling between a communications device and the computer it is attached to. As the standards body made revisions to the standard, and the EIA merged with the TIA, the name changed. EIA/TIA232 is the most recent and correct name however, RS232 is the most commonly used name. Ultimately they all refer to the same standard to define the interface between Data Terminal Equipment (DTE) and Data Circuit Terminating Equipment (DCE) employing serial binary data interchange.
RS232 Distance Limitations
While the standard does not define a maximum cable length, a widely used rule of thumb indicates that RS232 cables should be limited to 15 m (50 ft). An RS232 to Ethernet Converter is ideal when users want to replace RS232 serial cabling with Ethernet but maintain the use of devices that were active on the serial network. Ethernet cabling is generally run up to 100m (328ft).
RS232 Flow Control
Flow control on the IOLAN RS232 to Ethernet converter is accomplished through the use of software Xon/Xoff flow control, as well as hardware flow control with RTS and CTS signaling between DTE and DCE.
RS232 Control Signaling
As a DTE, the IOLAN presents DTR and RTS signals on its RS232 port(s). This is straightfoward when communicating directly with a modem or modem emulating DCE device. However, when connecting to another DTE device or when using RJ45 CAT5 cabling schemes, a crossover cable or converter is required. IOLAN cable accessories are available to assist with these connections.
Asynchronous RS232 baud rates typically range from 50K baud to 230K baud with some devices operating at speeds as high as 500K baud. While most RS232 to Ethernet converters on the market offer a limited selection of baud rates for communicating, the Perle IOLAN supports the full typical baud rate range and also offers customizable baud rates for those RS232 devices that require unique baud rates.
