Centrifuge data communications system
First Claim
1. A data communications system for a plurality of centrifuge instruments, each instrument having a programmable instrument controller therein, each said programmable instrument controller being adapted to control the operation of the centrifuge instrument with which it is associated in accordance with a predetermined set of operational parameters, wherein said data communications system comprises:
- a central data controller having memory therein, anda communication link connecting said central data controller to each of the programmable instrument controllers for communication therebetween,said central data controller being operative to transmit a predetermined command signal and a predetermined instrument address signal over said communication link,each said programmable instrument controller being responsive to the transmission of said predetermined command signal and to its respective instrument address signal by transmitting to said central data controller over said communications link the then-current values of at least some of the set of operational parameters for the particular centrifuge instrument.

Abstract
A data communications system for a plurality of centrifuge instruments, each with a local controller, includes a central data controller and a communication link that connects the central data controller to each of the instrument controllers. The link complies with Electronic Industries Association (EIA) Standard 485. The central data controller transmits a predetermined command and an instrument address signal over the link. Each instrument controller is responsive to the transmission of the command signal and to its respective instrument address signal by transmitting to the central data controller over the communications link the then-current values of at least some of the set of operational parameters for the particular centrifuge instrument.
