Overview AXIS 2490 User’s Manual Overview The old way of installing serial devices was by connecting them to PCs, either directly with serial cables or by using modems. This often required a lot of PCs, long cables, etc. The AXIS 2490 Serial Server makes it possible to connect serial devices directly to a network without using a PC, thus providing applications with convenient remote access to these resources via HTTP and TCP/IP.
AXIS 2490 User’s Manual Overview With its own built-in Web server, the AXIS 2490 allows direct access from any browser on the network and provides full Web-based control of the management and configuration functions. The AXIS 2490 Serial Server supports high data rates and high throughput. It enables 10 Mbit and 100 Mbit Ethernet network access to serial devices using TCP/IP or HTTP as the transport protocol.

The AXIS 2490 in Your Application AXIS 2490 User’s Manual Telnet RFC2217 Options COM port control according to RFC2217 uses telnet options in the data stream to encapsulate status and control information. It can be used to control the state of the control outputs (RTS and DTR) and to monitor the state of inputs (CD, DSR, CTS and RI). It can also be used to control the COM port settings, such as baudrate, parity settings etc. A COM port redirector that supports RFC2217 will configure the baud rate etc.
AXIS 2490 User’s Manual The AXIS 2490 in Your Application 2 Serial Servers used together create a "tunnel" and use the network as a "virtual extension cable" This alternative can be used to connect two serial devices or a serial device with a PC using an application that uses COM ports. See Tunnel Communication, on page 36 for the necessary settings. Generic HTTP The Generic HTTP mode gives you the ability to receive status/data and send commands via HTTP.

AXIS 2490 User’s Manual Updating the Software Appendix C - Updating the Software The AXIS 2490 software is stored in Flash memory. This memory is provided by a silicon chip that, just like any other ROM device, retains data content even after power is removed. Flash memory is unique because it allows its data to be erased and re-written. This means you can install software updates for your AXIS 2490 as they become available - without having to replace any parts.
The Unit Connectors AXIS 2490 User’s Manual Appendix D - The Unit Connectors This section provides a detailed overview of the Serial Server’s serial port connections: the two RS-232 Serial Ports, and the IO Block Connector, including the RS-422/485 Port. The Serial Connectors The two RS-232 serial connectors provide the physical interface for connecting serial devices to the AXIS 2490 and thus to the network.
AXIS 2490 User’s Manual The Unit Connectors communication is initiated. RS-485 is similar to RS-232, but without a signal ground and with double-wired transmit and receive data. The wires are TxD+, TxD-, RxD+ and RxD-. Data detection is done by measuring the voltage difference between the positive and negative line. This eliminates disturbance by interference, because interference appears identically on all lines simultanously. This means greater distances can be covered than with RS-232.
The Unit Connectors AXIS 2490 User’s Manual The RS-485/422 port A 4-wire RS-422/485 port (one TX pair and one combined RX/TX pair). The RX port can be used for both RX and TX (controlled by RTS) and for half-duplex RS-485. The port can be used in any of these configurations: • Full-duplex RS-422 (4-wire) or • 4-wire RS-485 or • Half-duplex RS-485 (2 wire) The port is compliant with EIA-RS-485 up to 1843200 bps.
AXIS 2490 User’s Manual Examples Appendix E - Examples Applications Access Control Devices Many buildings nowadays do not use door keys for controlling access, but instead use magnetic cards and card readers at each door or access point. Entering a code on a keypad is another alternative. Both the card readers and the keypads are connected to a computer that opens/unlocks the door.
Examples AXIS 2490 User’s Manual Surveillance and Alarm Systems in Buildings In places such as lifts and toilets, there might be a push button to activate a distress signal in case of an emergency. The button would be linked directly to the network via a serial server. Barcode Readers Barcodes and barcode readers can be found in many different locations, such as shops and factories. In production plants, different parts could have a barcode which would show where it belongs.
AXIS 2490 User’s Manual Examples Climate Control Monitoring of indoor climates includes heating, ventilating and air conditioning systems. These systems are usually connected to computers via long serial cables. A more convenient solution is if the building’s control systems are connected to a network via AXIS 2490 Serial Servers. This enables remote access and monitoring from anywhere in the network. Service engineers can also locate and identify errors.
