Make sure your THC board is installed correctly first. The red LED is on the THC control board that you installed on the Motion Control Board:
If the board is installed correctly, unplug the USB from your computer and then restart the computer. Wait for complete boot up and then plug in the USB to the LS control box. You should hear the tone as Windows recognizes the device. If you don’t hear the tone, you may get a message that Windows is installing drivers/device. After that start FireControl to check connection. If you get neither tone or message and FireControl does not connect, you definitely need to reinstall drivers.
Post back and if need be I will try to post instructions on driver install…
