    Default Cannot connect using LAN card

    I am having a similiar issue to other users in trying to connect to the profilux II unit over my LAN.

    I installed the LAN card into Slot 1 and configured the card with an ip address of 192.168.0.14 using the front panel of the profilux.

    Using the profilux control software I cannot connect to the unit even though it is visible on the network and I can connect using the ip address in a browser, which allows me to reconfigure the ip address and saves this information to the card.

    I have tried to auto configure the ip address, still unable to connect. I have moved the LAN card to slot 2 still unable to connect.

    I have tried a direct connection to the profilux, bypassing any routers or switches and have disabled the firewall on the computer.

    The only thing I am unsure of is the device address so I have tired connecting using address # 1, 2 and 3.

    I believe the issue is not related to my network configuration as the device appears on the network and I can connect to it sucesfully using the inbuilt server.

    did you change the baudrate in the inbuilt server and/or in Profilux?

    another idea - we noticed that there is a problem with some routers/switches if the LAN card uses "auto negotiation" for the LAN speed

    Please change this setting in the Lantronix built-in server:
    Network - ethernet configuration
    disable "Auto negotiate"
    chose 10MBps
    click OK
    click Apply settings

    No I did not change the Baud rate at all.

    I have changed the configuration to 10 Mbps and still cannot connect.

    If the card is plugged into the middle slot on my profilux what Device Address should I select in the software?

    Also the paperwork mention a program call redirector from www.lantronix.com to provide a Virtual COM-Port but this is not mentioned in the downloaded instructions, do I need this software?

    the device address is usually 1, independent from the used slot
    you don`t need the redirector, actually this part of software is included in ProfiLuxControl when you use "TCP/IP" under connection settings

    The port 10001 is used for transmitting data to ProfiLux - is there maybe a firewall which blocks this port? If you can see the built-in server you access standard port 80, so this means even if you see the server it is still possible that the other communication does not work.

    As per original post, I have directly connected to the profilux LAN car with no routers or firewalls involved, still unable to connect.

    I have tried to connect using the USB interface I previously used and that too is now failing to connect, even though it was previously working perfectly.

    I am unable to check the Serial port connection as I do not have a computer with a serial port.

    At this time I am unable to connect using any interface.

    Then you need a cross over cable to connect directly, it will not work without

    "As per original post, I have directly connected to the profilux LAN car with no routers or firewalls involved, still unable to connect."
    -> I meant the windows firewall (not a hardware firewall) - is it deactivated

    "I have tried to connect using the USB interface I previously used and that too is now failing to connect, even though it was previously working perfectly. "
    -> this is trange, it worked and now it doesn`t work any more? What was changed? PC-software, firmware-update, operating system?
    Please let us find from what event on the trouble started and let us go from there

    Windows Firewall deactivated, and no hardware firewall at all.

    I have tried it using both WinXP and WIndows 7 RC. The USB connection worked perfectly until I removed it to install the LAN card. I re-installed the USB Card so I could use the software while I sorted out what was wrong with the LAN connection. I have tried the USB card in every slot as I did with the LAN card.

    I was using Version 4.0.5.0 of ProfiluxControl but downloaded 4.0.6.1 to see if that fixed the issue.
