Serial-IP Converters
Serial-IP converters (more commonly referred to as Terminal
Servers or Device Servers) are hardware devices which convert
serial asynchronous data from an RS232 port to TCP/IP or
UDP packets. These converters or adapters are typically found
in 1 port or multiport models and include a 10/100 Ethernet
network interface.
What to consider when choosing a Serial-IP converter
Serial RS232 async start/stop characters in 7, 8 or 9 bit
formats are received by the Serial-IP converter and then
encapsulated in TCP or UDP packets. These packets are then
forwarded to a remote software based IP socket application,
another serial device connected to a peer Serial-IP converter
on the network or to a virtual COM port redirector software
utility like Perle’s TruePort.
Perle’s TruePort COM port redirector appears as a local
serial COM or TTY port to a serial application including
RS232 control signals. This enables a serial based application
to communicate directly over an Ethernet connection without
changes to the application software. TruePort is supported
on all major operating systems such as Windows, Vista, Linux,
Solaris, SCO and Unix and is included with all purchases
of Perle IOLAN serial-IP converters (Terminal Servers).
In order to ensure that the original serial data stream is
received by the other end point, it is important that these
Serial-IP converters have sufficient processing power to
handle high throughput serial data. They must also have the
ability to properly packetize the data onto TCP/IP packets.
Perle’s IOLAN Terminal Server and Device Server family with TrueSerial technology
greatly exceeds the performance of all other similar Serial-IP
converters on the market and provides the most authentic serial
connection across a TCP/IP Ethernet network. A wide selection
of models are available in both compact and rack sized form
factors.
