Using the AXIS 2490 Serial Server

The AXIS 2490 Serial Server allows serial devices to connect directly to an Ethernet network

without using a PC, thus providing convenient remote access to these resources via HTTP

and TCP/IP. A few examples of physical setups using the AXIS 2490 are shown below:

Ports

The AXIS 2490 is used for connecting serial ports to a network via the following:

• Two RS-232 serial ports on 9-pin male DSUB

• One 4-wire RS422 serial port on screw terminal block. This can also be used as a 2-wire

RS-485 port (direction controlled by RTS signal)

Each serial port operates independently of the others and can be used in these modes:

• Generic TCP/IP – used for communication using network sockets, with a COM-Port

redirector, or for tunnel communication between two serial devices or between a serial

device and a PC

• Generic HTTP – allows access via network browser (Netscape 4.x or Internet Explorer 4.x)

The Front Panel

Both ports support: RX, TX, RTS, CTS, DSR,

DTR, RI and CD.

unit to its default factory settings.

❶to ❸The application

uses a network socket or a

COM-Port redirector to

communicate.

An application that uses a

local serial port will not

work with a networked

serial port. To make the

server’s port appear as a

local port on your PC, you

must install and use a

COM-Port Redirector.

each other via a “virtual extension

cable”.

an old application that uses the serial port and

when you can’t use a COM-port redirector.

The Rear Panel

Network Connector

The AXIS 2490 is designed for 10

Mbps Ethernet and 100 Mbps

Fast Ethernet networks and con-

nects to the network via a

twisted pair category 5 cable

(10baseT and 100baseTX) termi-

nated using a standard RJ-45

connector. Supporting NWAY,

the AXIS 2490 detects the speed

of the local network segment

and varies the speed of data

communication accordingly,

between 10 Mbps and 100 Mbps.

Status Indicator

The yellow Status Indicator shows the unit’s operational

status, as described below:

• slow flash - indicates normal operation

• rapid flash - indicates a hardware failure

For the Status Indicator’s behavior during a reset to the

factory default settings, see page 4.

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 can be used for half-duplex RS-485. The port can be used for:

• 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.

Connecting the AXIS 2490 to the Network

Follow the guide below to quickly connect your AXIS 2490 to an Ethernet network:

❶Note the serial number on the underside of the

unit. You need to know this to set the IP address:

❷Using an appropriate method for your

operating system, assign your product with a

unique IP Address from a computer on your

network, as follows:

Note: In some Unix systems, the arp command can be located in a directory that is not on the

command path; e.g: /usr/sbin/arp.

You will now see ‘Request timed out ...’messages repeatedly returned in the window.

Windows 95, 98, NT and 2000 only - Start a DOS

window and type these commands:

Syntax:

arp -s <AXISServer IP address> <Ethernet address>

ping -t <AXISServer IP address>

Example:

arp -s 172.21.1.200 00-40-8c-10-00-86 172.21.1.193

ping -t 172.21.1.200

UNIX only - Type these commands

in the command line:

Syntax:

arp -s <IP address> <Ethernet address>

temp

ping <IP address>

Example:

arp -s 172.21.1.200 00:40:8c:10:00:86

temp

ping 172.21.1.200

❻Exit Ping. The installation is now complete, and you are

ready to access the AXIS 2490 from your browser.

connector ❸Connect an Ethernet cable to your AXIS 2490

and attach it to the network.

❹Connect the external Power Supply to

the unit and connect it to your main

power supply.

❺10-15 seconds after connecting the power supply, the message

‘Reply from 172.21.1.200...’ - or similar, is returned

within the window. Ensure that the Power Indicator is permanently

lit and that the Status Indicator flashes slowly.

❼Verify the connection to the AXIS 2490 by starting your

browser and entering the IP address in the location/address

field, e.g. 171.21.1.200. You should then see the AXIS 2490’s

Welcome page displayed.

❽You can now set up your application using the AXIS 2490. For more information,

see page 1 of this guide, or see the User’s Manual.

Refining the Installation

Click the Installation Wizard button. The wizard helps you complete the remaining

installation steps. For further configuration, click the Admin button. The buttons on the

Admin page provide access to general settings, port settings and settings for the network.

The information and screen examples shown here provide a very brief introduction to

configuring your AXIS 2490. For more detailed information, please refer to the AXIS 2490

User’s Manual, which can be obtained from www.axis.com.

Reinstating the Factory Default Settings

In certain circumstances, it may be necessary to reinstate the Factory Default settings for

your AXIS 2490. This is performed by clicking the appropriate button within the

Administration Tools, or by pressing the Control Button. Follow the instructions below to

reinstate the product factory default settings using the Control button:

1. Switch off the AXIS 2490 by disconnecting the power cable.

2. Press the Control Button and keep it pressed. Reconnect the power supply cable.

3. With the Control button pressed, the Status Indicator will now flash briefly and then go out.

When the Status Indicator has been out for about 5 seconds, release the Control Button. When

the Status Indicator starts to flash again after approximately 5 seconds, the AXIS 2490 will then

have been reset to its default settings.

Note: Reinstating the original default settings will cause all parameters (including the IP address) to be

reset.

Troubleshooting

Note: If you still have a problem after reading this information, please contact your reseller or

check the AXIS 2490 product pages at www.axis.com. The complete manual for the AXIS

2490 can also be obtained here.

Symptoms Possible causes Remedial actions

The AXIS 2490 cannot be

accessed from a browser.

The IP address is already used

by another device.

Disconnect your AXIS 2490 from the network, run the PING utility and

follow the appropriate recommendations.

The IP address is located on a

different subnet.

Run the PING utility. If the utility returns “no response” or similar, in

Windows 95/98 or Windows NT/2000, you should then check that the

IP address for your AXIS 2490 is on the same subnet as your

workstation.

If these subnets are different, the IP address cannot be set from the

workstation. Please contact your network administrator.

In Windows 95, the ARP

table was empty when you

tried to set the IP address.

If the table is empty, re-install the product, ensuring that the IP

address for your own PC is also used. Type arp -a to view the ARP

table.

Proxy server. Try disabling the proxy default in your browser.

Other networking problems. Try replacing your network cable.

Test the network interface of the product by connecting a local

computer to the unit, using a standard Crossover (hub-to-hub) Cable.

If the above actions don’t solve the problem, the AXIS 2490 may be

faulty. In this case, try to localize the problem by connecting the AXIS

2490 to the serial port of a local computer, using a Null Modem Cable

and report your findings to your local distributor.

The Power indicator is not

constantly lit.

Faulty power supply. Verify that you are using an AXIS PS-B power supply.

The Status indicator flashes

rapidly.

Hardware failure. Contact your Axis dealer.

Your AXIS 2490 works

locally, but not externally.

Firewall protection. Check the Internet firewall with your system administrator.

Default routers required. Check if you need to configure the default router settings.

"Unable to connect to

remote host: Connection

refused" or similar error

message.

The IP settings in the 2490

are wrong.

Check the IP number, router and netmask settings.

The TCP port number is

wrong.

Make sure you use the same port number the 2490 is configured for.

The 2490 is not in Generic

TCP/IP mode.

Check the settings in the 2490.

An established connection is

immediately closed.

Someone else is already

using the port and has

connected to the Axis 2490.

Select "View Log FIle" in the Server settings to see if anyone else has

connected. You may want to configure "Allowed IP addresses" and

restart the unit.

You have enabled "Allowed

IP addresses" but your IP

address is not allowed.

Check the settings in the 2490.
