摘要： In a network of a topology of a loop and a bus, occurrence of a failure is detected and a location of the failure is specified. Occurrence of the failure is detected by detecting that a specific signal pattern to be received at regular time intervals within a fixed time period is not received. A node which has detected occurrence of the failure transmits or receives a specifying signal among the nodes, and decide whether or not the failure has occurred adjacently to itself. A packet indicating a decided location of the failure is transmitted or received among nodes, and thereby respective nodes specify the location of the failure. When the failure has occurred at the master node, a node having a smallest node ID after waiting time according to the node ID operates as the alternative master node.

摘要： A master station 11 produces a token packet for isochronous data in which a slave station 12 and slave stations 13 and 14 serving as a sending station and receiving stations are designated using IDs for isochronous data “#2” and “#3” in accordance with contents described in a table 161 held in its inner part so as to manage a transmission bandwidth using a token packet sending/analysis executing device 16, and sends out the produced token packet to a transition path 15 on the downstream side. The slave station 12 sends out an isochronous data packet 42 using the token packet for isochronous data 41. According to the token packet for isochronous data 41, the slave stations 13 and 14 are designated as receiving stations using the ID for isochronous data “#3”, so that the slave stations 13 and 14 perform the above-mentioned operations, to receive the isochronous data packet 42. The sending station can thus transmit the same isochronous data to a plurality of receiving stations belonging to a broadcast group, so that it is possible to establish multicast communication (communication to a plurality of nodes).

摘要： A network system comprises a main loop in which one master node which issues a token packet for data communication, and at least one slave node are connected in a loop; a first sub loop in which the master node, one sub-master node, and at least one slave node are connected in a loop; and at least one second sub loop in which the master node, at least two sub-master nodes including the sub-master node of the first sub loop, and at least one slave node are connected in a loop. In this network system, each node has an analysis execution unit which performs analysis of the token packet, control of data transmission and data reception, and a switch for changing the connection. When each node receives and analyzes the token packet, it controls the switch so as to output, transmit, or discard the token packet and a data packet. Therefore, addition of nodes and loops is facilitated while maintaining the transmission efficiency, without increasing the packet transmission time.

摘要： A first initialization pattern signal is a signal in which a maximum signal level and a minimum signal level appear alternately, and a second initialization pattern signal is a signal in which all signal levels appear in a predetermined arrangement. In a ring-shaped network including plural stages of data transmission apparatuses (100), a transmission unit (110) of each data transmission apparatus outputs the first initialization pattern signal successively to a next-stage data transmission apparatus at turn-on of power or immediately after reset, and a reception unit (120) establishes clock synchronization on the basis of the first initialization pattern signal received. When synchronization is established in all of the data transmission apparatuses, the transmission unit (110) outputs the second initialization pattern signal successively to the next-stage data transmission apparatus, and the reception unit (120) sets evaluation levels for the respective signal levels on the basis of the received second initialization pattern signal, and transmission/reception of data is started when evaluation levels are set in all of the data transmission apparatuses.

摘要： A data transmission system in which normal transmission can be performed irrespectively of the inserting orientation of a connector is provided. A transmitting device transmits to a receiving device a differential transmission signal including polarity decision data for deciding the polarity of the connector. Based on the polarity decision data included in the differential transmission signal transmitted from the transmitting device, the receiving device decides whether the polarity of the connector has been reversed or not. When it is decided that the polarity has not been reversed, the receiving device reads data from the differential transmission signal. When it is decided that the polarity has been reversed, the polarity of the differential transmission signal is reversed for data reading.

摘要： To a data reception device, a signal having a frequency of 12.5 MHz and including data is transmitted. The data reception device generates a clock B having a frequency of 400 MHz of (1) in FIG. 8, and performs sampling for the above-described 12.5 MHz signal based on the clock B ((2) in FIG. 8). Then, the data reception device detects zero cross points of the sampled data, and generates a 25 MHz frequency clock signal indicating the zero cross points ((3) in FIG. 8). Next, the data reception device generates, by delaying the generated clock signal by the time amount corresponding to eight clocks ((4) in FIG. 8), a 25 MHz signal indicating symbol points. Thus, symbol points can be detected.
