The AXIS 2490 in Your Application
The AXIS 2490 can be used in a wide variety of applications. Installing directly onto an
Ethernet network, the product is completely independent and requires no additional
software, unless you plan on using a COM-port Redirector (see below).
This section will help you prepare for the installation and configuration of the unit. Not to
be regarded as a comprehensive catalog of possible applications, the section describes
several typical general applications. For more examples of applications, see Examples, on
page 35.
Networking Applications
Traditionally, serial devices have always been connected to PCs, either directly by cables or
via modems. Now, however, you can use an existing Ethernet network (LAN/WAN) to
connect to your serial device. Using the AXIS 2490 Serial Server as the link between the
serial device and the network, simply connect the device to the AXIS 2490, which in turn
plugs into the LAN/WAN. Lastly, set the IP address for the Serial Server and you’re ready
to start using your serial devices over the network.
Port Modes
The Serial Server has two operational modes: Generic TCP/IP and Generic HTTP. The mode
can be set independently for each serial port: (two RS-232 ports and one RS-422/485 port).
Generic TCP/IP
This mode is as a data connection for transparent communication, where the AXIS 2490
can act both as a server and a client. The mode can be used for the following
configurations:
Remote access using an application with network support
The AXIS 2490 supports the Telnet option for COM port control according to RFC2217.
This is one example of how the setup shown below can be used. Please see Protocols, on
page 27 for a complete list of the protocols supported.
