Do NOT attempt to download or install any device drivers for the USB to Serial cable from the internet. Windows must use the device driver it selects and installs on its own.
If you have an older USB to Serial adapter (the short translucent blue and silver cable) which was purchased before March of 2016, then to work with recent versions of Windows, you will need to purchase a new USB to Serial adapter from
FarmTek or a computer store. To purchase from FarmTek, contact us at 972-429-0947.
To determine if you already have the compatible USB to Serial adapter, look for the LED in the blue connector while the cable is connected to a powered on computer as shown here. If you see an illuminated LED, the cable is is compatible
with recent versions of Windows. Otherwise, a new USB to Serial adapter must be purchased.
To access the Windows Device Manager under Windows 10 and Windows 8.x, press and hold the Windows key (bottom left corner of keyboard) and type an "X". A menu will pop up near the bottom left of the screen. Left-click on "Device Manager."
