For the remote session, you will need a Windows computer (with Windows 7 or later), an FTDI serial to USB cable (click to purchase) if you have an older clock with a Serial rainbow cable on the back (click to purchase) or a USBA to USBB cable for 500CCM or newer green-backed clocks, an internet connection, and TeamViewer (click to download) on a Windows computer connected to the clock.
It is crucial on older clocks that the USB to serial cable has an FTDI chipset, if the wrong cable is acquired we will have to reschedule the remote session.
