| TCP |
|---|
|
Using RAW TCP Sockets A raw TCP socket connection which can be initiated from the serial-Ethernet 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 serial-Ethernet adapter. .jpg) |
| UDP |
|
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.  |
| Console Server |
|
Console Management For access to remote console ports on routers, switches,etc, Perle IOLAN’s enable administrators secure access to these RS232 ports via inband Reverse Telnet / SSH or out of band with dial-up modems. Perle IOLAN models with integrated modems are available.  |
| COM/TTY |
|
Connect Serial-based Applications with a COM/TTY Port Driver 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 TruePort. .jpg) |
| Tunneling |
|
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). .jpg) |
| Virtual Modem |
|
Virtual Modem (Ethernet Modem) Enables the serial-Ethernet adapter 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 adapter configured with a Virtual Modem serial port or to a host running a TCP application.  |
