AXIS 2490 Serial Server
Network Access to Serial Devices

With the AXIS 2490 Serial Server it is now possible to extend RS232 full-duplex communication over intranet networks and the Internet, allowing you to fully utilize serial port devices that were previously slaved to a host via a length of cable. 

Complete with its own built-in Web server and unique IP address, the AXIS 2490 installs onto any 10 or 100 Mbps TCP/IP network to provide direct network access, control, and management of serial devices.

The AXIS 2490 has two RS232 ports and one RS485/422 port which can be used in either 2 or 4 wire configuration (RS422). Data can be transferred back and forth from several serial devices in multi-drop configuration via the Terminal Block connector. The serial devices are accessed from a standard desktop browser or other application that uses serial or network communication.

Protect earlier investments in non-networked serial devices with the new AXIS 2420 Serial Server — and enjoy serial port access through network connectivity.

  • Direct access, configuration and management from a standard Web browser

  • Extends RS232 data communication over intranet networks and the Internet

  • Supports up to two RS232 ports and one RS485 port

  • Password protection with user and IP address filtering

Technical Specification - AXIS 2490 Serial Server
 
Technical Overview Physical Network Connection Serial Connection
• Simply assign an IP address using ARP/PING, BOOTP or AXIS Utilities. Access and configure the product using a standard Web browser. Optionally install a COM port redirector software for use with a personal computer client.

System Requirements
• The AXIS 2490 uses the standard Internet TCP/IP suite of protocols and can be used with most operating systems: Windows 95/98, Windows NT/2000, Linux, UNIX, Mac, and several others. The only software needed is Internet Explorer 4.x or Netscape Navigator 4.x for configuration and an application supporting TCP/IP or a COM port redirector

Additional Software
• Optionally install commercially available COM port redirector software on your workstation and create a virtual RS232 port that sits anywhere on your network. A COM port redirector allows existing Windows software to access networked attached serial devices. You can download Axis’ unsupported Virtual COM Port Driver software for Windows NT, 95, 98 and 2000 free of charge from our Website at: www.axis.com
• The AXIS IP Installer, used to assign IPaddresses, is also available from our Website.

Supported Protocols
• ARP, BOOTP, TCP, IP, HTTP, ICMP, FTP, and DNS. Raw TCP/IP connections for communication with the attached serial devices. Telnet options can also be enabled for
COM port control according to RFC2217. HTTP can be used to communicate with those serial devices that support it.

Configuration and Management
• Product configuration and status monitoring using a standard Web browser; such as Microsoft Internet Explorer 4.x or Netscape 4.x. Includes FTP support for uploading and/or downloading product configuration files.

 • Physical network connection on 10BaseT Ethernet or 100BaseTX Fast Ethernet networks using RJ45 twisted pair cable (Category 5 shielded or unshielded twisted pair cable).
Note: Shielded cable is recommended for industrial environments.
