Mother Pba - Toshiba DP120F Service Manual

5. MOTHER PBA

This section describes the functions of the Mother PBA.
The Mother PBA relays signals and power supplies between the Main PBA and each PBA and
is connected to CN12 and CN13 on the Main PBA.
The Mother PBA relays the control signals sent from the Main PBA to each PBA connected to
the Mother PBA and relays the status signal of each sensor connected to the Mother PBA, to
the Main PBA. It also relays the power supply delivered from the LVPS to each PBA.
The Mother PBA simplifies the harness connection between each PBA or I/O equipment and
the Main PBA, thereby making more efficient the attaching and detaching operations for the
Main PBA.
