If you do not see Ports (COM & LTP) in the list, then either the interface cable has not been connected, or the drivers have failed to install. Ports (COM & LPT) will only display if you have a COM port or LPT port installed. (LPT ports refer to parallel printer ports - but you do not need to worry about them in this instance).

  7. View available Ports

  8. Windows - View Available PortsIf you can see Ports (COM & LPT), then click the little triangle to the right of Ports (COM & LPT), or double click on Ports (COM & LPT), and you should how see all of the ports installed on your computer drop down as part of a tree display.

  11. Double click on the USB Serial port shown, (in this demonstration case it is COM18, but yours may well be different) and you should now see the property window for that port.
  12. Check that the title shows the COM port, and the Manufacturer shows FTDI as well as the device status showing as "This Device is working properly". If it shows another manufacturer then you might be looking at a different interface. A correctly installed driver and an official E-Stim Systems Digital interface will always show the manufacturer as 'FTDI'


If you don't see the Digital Interface, or if you don't see Ports (COM & LTP) in the list, then either the cable is not correctly connected to your PC, or the drivers have not installed correctly.
