RPC jumper location for Pioneer DVD drives

Before using the drive, be sure the RPC jumper is inserted. If not the drive will become RPC-2 (zone locked) after the first DVD insertion, definitively!!! Once RPC-2, the drive is detected with a R (ex DVD-103 became DVD-103R)
Even a firmware upgrade couldn't change anything. You could change your region only 5 times.
After the fifth time, it will stay with the last region programmed.
RPC pin on the new 10X drives do not works (DVD-104S / DVD-114).

Jumper location for IDE drive (DVD102/A02 - DVD103/A03 - DVD-113)

Jumper location for SCSI drive (DVD-302/U02 - DVD-303/U03)
