Updating TT4

Clint Bradford #150 Confirming all I need to (a) update firmware and (b) update settings for my TT4 is a null modem cable - from it to an older Windows laptop also with a 9-pin serial port? (Clint has some time on his hands ... )
Rob Giuliano All Messages By This Member #151 That and a way to power the unit. Unfortunately, the TT4 cannot get power from the old DB9 serial cables - at least not without some extra components. You could try JP6 set to Vin, but it didn't work for me. I'd recommend JP6 removed so that port settings (hardware flow control) won't cause problems Byon and Allen would know better about that last point.
