Perle’s RS485 to Ethernet converters (commonly referred to as Terminal Servers or Device Servers) connect RS485 based equipment across an Ethernet network enabling you to do such things as:
With the broadest choice of full featured RS485 to Ethernet solutions available, Perle has the right product to meet your RS485 to Ethernet conversion project.
RS485 data sent and received on serial ports on the RS485 to Ethernet adapter are encapsulated in Ethernet packets in a manner that best fits the type of data being transported.
Perle's line of IOLAN RS485 to Ethernet adapters are extremely flexible and can match your specific application requirements. Described below are just some of the possibilities.
Using RAW TCP Sockets
A raw TCP socket connection which can be initiated from the RS485 device 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 RS485-Ethernet converter.
Using Raw UDP Sockets
For use with UDP based applications, Perle IOLANs can convert serial equipment data for transport across UDP packets either on a point to point basis or shared across multiple devices.
For access to remote console ports on routers, switches,etc, Perle IOLAN’s enable administrators secure access to these RS485 ports via inband Reverse Telnet / SSH or out of band with dial-up modems. Perle IOLAN models with integrated modems are available.
Connect RS485-based Applications with a COM/TTY Port Driver
RS485 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 TruePort.
Serial Tunneling between two RS485 Devices
Serial Tunneling enables you to establish a link across Ethernet to a serial port on another IOLAN. Both IOLAN RS485 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).
Enables the RS485-Ethernet converter to simulate a modem connection. When connected to the IOLAN and initiates a modem connection, the IOLAN starts up a TCP connection to another IOLAN serial-Ethernet converter configured with a Virtual Modem serial port or to a host running a TCP application.
