Hello.
the LEDs connected to the Pro-Shift automatically light up when you open the Pro-Shift configuration screen in SimDash.
you don't have to do anything and the LEDs light up.
With the DLC-247 instead, when you open the DLC-247 configuration screen the LDEs and displays that are connected stay switched off.
you have to press the TEST buttons on the right-hand side of the configuration screen to switch the LEDs and displays ON, for testing them.
what have you connected to the Pro-Shift and DLC-247 at the moment?
is it possible that the connected LEDs and displays are connected wrong?
for example, with the Pro-Shift, there is a correct way to connect the LEDs. if you connect them the other way round they won't work.
thanks
Cristiano
