it seems that it is possible to program the tipro boards via RS232 (and a USB-R232 adapter) using this cable.

Who does have this cable and could measure the pinout, i.e. could determine which pin of the RS232 connector is connected to which pin on the keyboard side?
Because an USB-R232 adapter is quite cheap. So you would get an good alternative to buying an Tipro USB controller.
