Unable to change IP address for LightCrafter

Cheung Ka Yan
Prodigy 225 points

Yesterday we have received two new LightCrafter DLPs for the project. But we found that ONE of them was not able to change IP address.

We receive "Command SUCCESS" message on GUI after we set the new IP but the IP is still the old one after we reset the device.

Both device are with same firmware version, and we have re-update the malfunctioning device but it didn't work.

We have even grabbed the TCP/IP packets and found that both send & receive packet data are correct.

Now we are completely confused. PLEASE HELP!!!

    Hi Cheung Ka Yan,

    Below is the procedure for connecting more than one LightCrafter to a PC,

    1. Connect ‘first’ device to your PC using GUI. Change the IP address in the “Connection” tab, click on ‘Change in LightCrafter’ button and wait until the command is successful.

    2. Power cycle the LightCrafter. Before clicking on ‘Connect’, change the Current IP address to reflect the new value.

    To connect to the GUI, manually change the “Current IP Address” value to 192.168.1.115.

    3. Now, click on ‘Connect’ and you should be able to establish a connection with the device.

    4. For the second device, repeat steps 1, 2 and 3 but make sure the IP address last subnet is 2 numbers higher or lower than the previous one.

    In the above case, since 192.168.1.115 has been assigned to the LightCrafter, the virtual IP on the PC would be 192.168.1.114.

    You can check the IP configuration by typing ipconfig in cmd terminal.

    Hi Divya:

    Thanks for your reply!

    But I am afraid the problem is not solved.

    Note that we have 2 identical devices. When we configure them on IP address individually (configuring one device without the other one being connected), using same procedure, we found that one of them can always be configured, the other one fail(Unable to connect using the configured address, but using the original one).

    But we receive "COMMAND Success" feedback in both case from GUI 3.8.

    And it is strange that the sent and received packets' data shows the configuration command is success.

    Thus we suspect there is a defect in the failed device.

    Any more suggestion for our case? Thank you!

    Hi Divya, Sorry for the inconvenience!

    Origin state

    Change IP

    REBOOT the device

    Cannot connect using the configured address...

    ...but the original one.

    The DHCP service address from device remains the same.

    Grabbed packets during configuring.

    COMMAND packet

    COMMAND REPLY packet

    All ip config

    Please help to judge. Thank you!

    Hi Cheung Ka Yan,

    Sorry for the delay. Are you able to change the Display Modes and project patterns with the default IP address on this LightCrafter?

    One workaround is to change the IPaddress in the LAN properties manually as mentioned by Stuti in this E2E post. I will look into this and let you know of my findings.

    Thanks,

    Divya

    Hi Divya,

    The Change Display Mode and Project Patterns work fine. So far we have only discovered problem in changing IP address.

    And we have read the workaround. Seems it talks about how to apply a static IP address to PC so that no time consumed on acquiring IP address from the DHCP server in LightCrafter. While our problem is unable to change the IP address of LightCrafter.

    Thanks for your work. We are looking forward a solution coming out soon! :)

    Hi Cheung,

    Can you please try one more thing,

    Before assigning 'New IP Address' in the GUI, change the IP address in the Network connections as follows,

    • Go to Network Connections. Right click on the new LAN connection, and choose "Properties"
    • In the box "This connection uses the following items" under the Networking tab, look for “Internet Protocol Version 4”. Highlight by clicking on it, and then click “Properties” underneath the box.
    •  Choose "Use the following IP address" and enter the address and subnet mask you would like to assign (192.168.1.101). Power-cycle the LightCrafter.

    Now, change the IP address (192.168.1.102) in GUI and see if you are able to connect. Please let me know of your findings.

    Regards,

    Divya

    Hi Divya:

    Happy Lunar New Year! Thanks for the reply!

    We've tried the method and it doesn't work.

    Here are the screen captures:

    Hi Cheung Ka Yan,

    Thank you and I wish you a very Happy Lunar New Year :)

    I wonder why the DHCP server address is not changing for this LightCrafter. The DM365 command sets this value and I request you to reload the DM365 build booting from NAND and try connecting.

    Regards,

    But the operation of modifying IP address is still not working. The phenomenon is identical with the one before.

    And actually we have tried to re-upgrade all firmwares before but it doesn't work.

    Does this possibly show the existence of a hardware defect?
