Abstract
A communication system between a microprocessor based device and a network of a plurality of remote input/output repeater modules uses a synchronous serial communications protocol. The microprocessor based device contains a transmitter module for generating a data packet containing the status of output device connected to remote input/output repeater modules coupled to the network. A receiver module also contained in the microprocessor based device receives and decodes a returned modified data packet that indicates the status of input devices connected to the same or other remote input/output repeater modules also coupled to the network. The receiver module can detect errors in the returned data packet.
