DLPNIRSCANEVM: Changing IP Address of NIRscan EVM to Add to Local Network

Part Number: DLPNIRSCANEVM

Hello, 

For the project I am working on, I need to control the NIRscan through a computer that is connected (through Ethernet) to a small local network of other computers. However, whenever I connect the NIRscan through USB over Ethernet to one of the computers on the network, the computer can successfully connect to the NIRscan, but it looses connection to the LAN network. I believe this is a problem because the NIRscan has a set static IP address (192.168.0.10) that takes priority over the previous LAN connection of the computer. 

Therefore, I think that in order to solve this problem, I will need to register the NIRscan on my LAN by manually reassigning the IP address of the NIRscan so that the computer can be simultaneously connected to the LAN network (over Ethernet) and also the NIRscan (either over USBoverEthernet or just straight Ethernet). I tried changing the IP address of the NIRscan by ssh-ing into the device (at root@192.168.0.10) and then running 'ifconfig eth0 192.168.X.XXX".

At first this seemed to successfully change the IP address assigned to the Ethernet port, however I still could not maintain connection between the LAN network and the NIRscan. So my main question is, is there a way to control the NIRscan through a computer on a LAN so that the computer maintains connection to the other devices in the network and the NIRscan? Has anyone come across a similar issue? Any help is greatly appreciated! 

Thanks, 

Justin

  • Hi Justin,

    This isn't an issue that I've experienced before. On my computers, usually the RNDIS driver is separate from the Ethernet driver and I've never had a conflict or been kicked off. My first step would be to investigate the driver settings on your machine to see if there are any setting there you can tweak first. I'll need to look into changing the default IP address, it's not something I've done before but I fear is not going to be a simple task. It likely involves recompiling the code.

    Maybe other users will be able to contribute in the meantime. I'll see if I can learn anything about changing the IP address.

    Best,
