I am very pleased with my new VM110 USB experiment interface board, it works perfectly when I plug it into my laptop. All of the LEDs light and inputs work when I use the demo program K8055_DEMO.EXE. However, I am trying to control the board over my WAN and then over the internet (ie remotely). When I do this the inputs are show okay on my laptop but when I try to control the outputs the application on my laptop hangs and the LEDs on the circuit board don’t light. I don’t think it’s my router set up as my laptop can detect the USB port (inputs show), but it just can’t control it 100%. I would be grateful if you could help me? Robert Kent
Your problem is extremely vague… i can’t make heads or tails of it
So you have two laptops (?), one with the board attached, one laptop that connects to the other via some sort of TCP/IP application (?), …
Does everything work with the demo application?
Sorry I’ve not used one of these on line help lines before.
So back to basics, yes the USB board works okay when plugged directly (ie single USB cable) into my laptop or main PC desk top.
It only partially works when plugged into my Belkin router via a local USB/Ethernet hub. Here only the outputs come up on the screen when I press the test buttons. When I try and control the outputs no LEDs light and the application hangs and I have to kill the application running on my laptop with the Xp Task Manager.
I am trying to control my USB board over the web to pick some relays to control lights in my house. I only want my laptop to be powered on (not my home PC), when I am not at home so, I guess, my Belkin ADSL/Wireless router will need to direct the controlling telegrams to the USB board directly via the Ethernet/USB hub that I have.
I have tried using the AbelCam interface and this does not help but I may have the settings wrong in my router (port/TCP/IP).
Thanks for your help, if you could explain what I need to do it would be of great help.

I think the driver and software has to be specifically designed to be able to work with your USB-to-Ethernet Hub. The hub sounds cool but the chances of it working are slim I think.
Your best solution might be to use your home PC instead of the USB hub as an intermediary.
Usually you will need to set up ‘port forwarding’ on your router; put simply: tell your router that a specific port should be directed to your home pc / router (since you can have multiple pc’s in your network).
