If your I-CubeX setup needs to be all over the place the USB-CableExtender will be useful to enable a greater distance between USB-microDig and computer. It converts the USB signals so that you can use regular CAT5 ethernet cables up to 45 m long (not included with the USBExtender) ! If it turns out to work great as trip wire we really recommend you to consider going wireless with the Wi-microSystem.
