Installing the USB to serial converter for the EGM-4

We’ve had some installation problems with the EGM-4: these have been linked to the IOGEAR USB serial adapter (GU232A) not installing properly. Note the installation disk with the USB to serial adapter is not compatible with 64 bit operating systems. If you’re having problems installing the USB to serial adapter follow these instructions:

  1. Check your system software in System Properties; System type (32 or 64 bit) and operating system
  2. Go to this site:
  3. Choose the correct driver software for your computer. Click download and when finished, unzip the zipped file and save to a known location.
  4. For Windows 7 64 bit; now plug in the USB to serial adapter to your computer (important: please remember which USB port you have used) and wait for several minutes- windows should automatically install the driver. To check, go to Computer, System Properties, Device Manager, Click next to Ports (COM and LPT) and you should see “ATEN USB to Serial Bridge”. If nothing has happened after several minutes, look in Device Manager and you should see an exclamation mark next to “USB serial converter D”; right click on this and a window should appear with an option to select the driver manually; you can navigate to the folder where you saved the driver and install it. Once it is installed you should see the name has changed to “ATEN USB to Serial Bridge in Device Manager”.
