This only happens when we run out of the spare digitizers for certain color. The only configuration needs to be modified is the jumpers. The right most one (master) must have two vertical jumpers. The left-most one must have the lower horizontal jumper. The two middle ones have no jumpers set.

The threshold setting needs no change. Since the computer will get energy range info from the boards and change the threshold accordingly.

After the replacement of the digitizer, verify the firmware version of the new digitizer.
