Abstract
A system for enabling and programming a plurality of pumps wherein each pump can be selectively enabled and loaded with an application program. Each pump also has an interface port. The system comprises a central computer having a storage medium configured to store a plurality of application programs and a remote computer. The remote computer has a first interface arranged and configured to be operatively connected to the interface port of the pumps, a second interface arranged and configured to be operatively connected to the central computer, and circuitry operatively connected to the storage medium, the first interface, and the second interface. The circuitry is configured to generate an enable signal for selectively enabling a pump, and if one of the pumps is operatively connected to the first interface, download an application program from the storage medium in the central computer to the operatively connected pump and transmit the enable signal to the operatively connected pump, thereby causing the pump to become enabled. A data manager stores information to track the application programs and the pumps. A disable signal is generated to later disable the pumps. A security system using checksum values is also provided.
