Help connecting to the COM.

Question

I have the 1.1 version of this software. It works, but sometimes it has some glitches. I'm trying to make this version work, but I can't seem to be able to connect with the COM. If I try to send something to the sign it displays: Failed to open COM! Also in setup I already followed the instructions of the tutorial/help section, but when I try to look for the COM it cant find it. Any suggestions on what I'm doing wrong?

Answer 1

The COM refers to the PORT. If you can't connect to the port, then there is something which blocks the connection from the software to the device through the COM port. I recommend re-installing the drivers. Go to Device Manager using Start > Run > devmgmt.msc and locate the COM ports. Right click the device and select uninstall. Install the software and drivers again and connect to the computer.
