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.

Specifications

• Model Number - AXIS 2490
• System Requirements - TCP/IP on Windows 95, 98, NT/2000, Linux, UNIX, Mac and several others. Microsoft Internet Explorer 4.x or higher, or Netscape 4.x or higher.
• Protocols - ARP, BOOTP, TCP, IP, HTTP, ICMP, FTP, and DNS. The serial server supports telnet options for COM port control according to RFC2217.
• Network Management - Configuration and status via standard HTTP browser. Microsoft Internet Explorer 4.0 or Netscape 4.0 or higher. Possible to use FTP to upload/download configuration files.
• Network Connection - 1 RJ-45 connector (Category 5 shielded or unshielded twisted pair cable) for 10BaseT Ethernet or 100Base TX Fast Ethernet. (Shielded cable recommended for industrial environments).
• Additional Software - A COM Port Redirector, which allows existing Windows software to access networked attached serial devices, can also be used with the serial server. For more information about COM-Port Redirectors, please see the AXIS 2490 product pages at www.axis.com. The Axis IP-installer can be used to assign IP-addresses.
• Security - User-level password protection. It is also possible, when using the ports in TCP/IP mode, to specify Allowed Users and Allowed IP addresses. These settings will disallow all other IP addresses and users.
• Software Updates - Flash memory allows central and remote software updates over the network using FTP over TCP/IP. All software upgrades are available free of charge from the product pages for the AXIS 2490 at the Axis Website www.axis.com.
• CPU - 32 bit RISC processor (ETRAX 100).
• Memory - Flash Memory - 2MB. RAM - 8MB.
• Serial Connectors - Two RS-232 serial ports, 9 pin MALE D-SUB. Both support: RX, TX, RTS, CTS, DSR, DTR, RI and CD. Supported speeds of up to 115200 bps. MALE 9-pin DSUB (RS-232 levels) (X3 and X2)
• 1 RS-485/422 serial port - Supports speeds of up to 1843200 bps
• Delimitations for RS-485/422 - RS-485 and RS-422 are similar, although there are differences in the electrical specification. Most driver circuits are compatible with both, at least for the receiver part. The AXIS 2490 Serial Server is primarily designed to work with RS-485 devices, although it will probably work with most RS-422 devices as well. A terminating 100-120 Ohm termination resistor might be needed between RX+ and RX-.
• Operating Temperature - +5 to +50 ° C.
• Humidity - 8-80% RHG, non-condensing.
• Dimensions (H x W x L) - 27mm x 112mm x 110mm
• Weight - 0.32kg
• Power Supply - Power: 9-24 V AC (or DC), 6 VA, via external power supply (PS-B). Typical power consumption is 2,5-3,5 VA.
• Mechanical Design - Stable aluminum metal casing, with screwholes for wall mounting.
• EMC and Safety approval - The AXIS 2490 Serial Server fulfills both industrial and light industrial/commercial EMC standards for emission and immunity, and Standards for Safety.
• Safety Standards - EN 60950, UL, CSA.
• Warranty - 1 year.
• AXIS Chipset Technology - The AXIS 2490 Serial Server comprises Axis’ own ETRAX 100 32-bit RISC processor and embedded Linux. See http://developer.axis.com for info about our embedded Linux.
