■ Setting of the user port power supply
Use the user port power supply setting jumper on the adapter board to set the reference voltage of
the user data bus probing circuit.
The user data bus for which the reference voltage is set corresponds to user port 0 or 1. Set the user
port reference voltage for each user port power supply.
See "■ Setting of the user data bus" for details on the user data bus probing circuit.
