    摘要: In a store data communications system, multiple data sources having disparate communications standards are connected with respective device interfaces of a multiple device communications controller unit. Multiple protocol controllers are coupled with the respective device interfaces and convert the data from each to a common protocol for transmission via a single telephone line. The interface units preferably can be customized to operate with various data sources, a fiber optic coupler, or a modem, or another controller unit for convenient expansion. The device interfaces preferably have snap-in assembly with the controller unit so that device interfaces customized to different standards can be inserted or replaced at any interface receptacle, the multiple protocol controllers preferably being capable of corresponding re-programming by downloading from a remote station preferably via one of the device interfaces.
