DLPC300: Cannot connect to DLPC300

Part Number: DLPC300

Hello,

In Win 7, the TCP-IP settings for the DLCP300 are set to be

You can test these to see they are set OK:

But in order to communicate with it, in the GUI (V5.0), we have to set the IP as 192.168.1.98, which is not correct since it is actually192.168.1.99.  We can ping 192.168.1.98 but not 192.168.1.99! Since we use the C++ code samples provided by TI, our program, therefore, does not work. What's is it that we are setting wrongly?

  • Cem,

    Have you tried checking if your IP configuration settings could be customized by recompiling the LightCrafter SDK? There is a link to it below:
    www.ti.com/.../dlp-alc-lightcrafter-sdk

    Otherwise, I'll see if I can find anything regarding the default IP assignment provided by the LightCrafter 3000 EVM.

  • Cem,

    Please see my reply to other thread. I recommend you use SDK base to rework IP settings to match your system.

  • Hello Philippe,

    Thank you for your response. As mentioned in the manual, LC sets the IP Address for TCP/IP connection at 192.168.1.99 (with DHCP/Gateway address as 192.168.1.100). I have one device that I finally connected through LC GUI, but I had to set its communication IP to be 192.168.1.98. If it is 192.168.1.99 as default, I cannot connect to it. Therefore, our test program does not work (it complains that “(Connect) Could not connect the projector properly”, “Unable to Connect to server, the projector”). I can ping ..98 and ..99 (see attached) but not ..100 (On working units I can ping ..99 and ..100).  I looked at the C++ code controlling the LC. There is a definition in a program called  “lcr_packetizer.h”,  in which LCR_CMD_IP = 192.168.1.100. Is it because the IP is ..98, our program does not work? If I do not set the IP through OS to be .99, and let the program automatically obtain the IP, LC sets the IP to be ..97, and I can connect to GUI, but our program does not work in this case either.

  • Hello Philippe,

    The only way I resolved this TCP/IP addressing problem was to reburn the DM365 firmware again. Aftyer that Windows reported the default IP and Gateway addresses (192.168.1.99, and 192.168.1.100 correspondingly). Oterwise none of the test made any sense. So teh solution fro similar cases is to reload the Dm365 firmware.
  • Thank you Cem for sharing information.
