(GC) RS232 Connection Troubleshooting with GC-2010

You should be able to determine the COM port it's connected to in Device Manager within Windows.

From there, in the LabSolutions RealTime software go to the assistant toolbar, Main -> System Configuration (at this point can you please send me a screenshot of the system config) ->Properties -> check Communication -> Settings... -> edit Communication and COM Port accordingly.

When you press okay and close these windows using the 'OK' button, then close System Configuration with OK and it should take a second or two to load then you will hear an audible beep sound when the system connects to the PC.
