Abstract: A mailing machine base includes a docking system for a User Interface Controller (UIC) that provides a feedback signal to the mailing machine based on the presence of the UIC. When the UIC is inserted into a docking connector of the mailing machine, the mailing machine detects the presence of the UIC. A delay circuit within the mailing machine provides a signal to a power control circuit after a predetermined time delay. The power control circuit, based on the signal from the delay circuit, will provide power to the UIC only after the UIC has been securely docked for the full predetermined time delay. When the UIC is removed from the mailing machine, the mailing machine, based on the feedback signal, will quickly remove the power provided to the docking connector. Thus, the mailing machine can remain powered during removal and replacement of the UIC.

Abstract: A mailing machine that includes a docking system for the User Interface Controller (UIC) that provides a safety interlock to protect the user from accessing potentially hazardous voltages when the UIC is removed is provided. A docking board provides a connection between the mailing machine and the UIC. The UIC mates with a docking connector on the docking board. Potentially hazardous signal levels pass through a relay on the docking board to the docking connector. A supply voltage for the relay's coil passes through docking board to the UIC and back to the relay on the docking board. If the UIC is removed, the supply voltage for the relay's coil will be removed, causing the relay to open and preventing any of the potentially hazardous signals from being transmitted to the docking connector on the docking board.
