Yes, that's the concept.
Also for downhill races where the start and finish are miles apart & completely obscured from each other, meaning TEDs are ineffective (even chained together), and there are no existing cables.
Have the Timy or ASC2 record the ST, send the ST via an SMS or connect to the Timy from the finish via serial over IP.
A PC at the finish pushes the ST into the TDC, and as you say there are logs of the STs. The Timy needs to be sync'd to the TDC, but that's easy enough.
There are several times this would be very handy for us, I wish they'd implemented it with hundreths to begin with!
The Timy's can be connceted over GSM, but then you lose the benefit of the TDC.
It's been mentioned to Alge before, was hopefull that perhaps it might have made it into the firmware.
