Electronic control device for high performance printer, has parallel data bus, and microcontroller that is provided on input/output module for controlling combined data transfer over data bus and serial data connection

摘要

The device (1) has a parallel data bus (5), and an input/output module (2) that is connected with the bus. A processor unit and a memory unit are connected with the data bus by a multi-bus module. The input/output module comprises an interface to a serial data connection for transmitting data. A microcontroller is provided on the input/output module for controlling a combined data transfer over the data bus and the serial data connection. An independent claim is also included for a method for operating an electronic control device.
