Abstract: A method of detecting master/slave response time-out under continuous packet format communications protocol, which calculates the time required for the slave device to respond to a Modbus request subject to Modbus TCP/UDP protocol. The method is to continuously send Modbus requests to a slave device through a detection device and to record each Modbus request sent time, and to have the slave device provide to the detection device a response for each Modbus request. By means of calculating the precise response time-out from the response time-outs which are gotten from the slave device responds to a predetermined number of Modbus requests, the user or manager can determine the response time-out required for the slave device precisely so as to give an EXECUTE instruction or command at the accurate time point.

Abstract: The present invention discloses a method for receiving data by a universal asynchronous receiver transmitter, which includes a receive shift register (RSR), a receiver FIFO, a receiver buffer register (RBR), a line status register (LSR), and a good data length register (GDL). The RSR is connected to the receiver FIFO and the LSR in parallel. The receiver FIFO is further connected to the RBR, and the LSR is connected to the GDL. The receiver buffer register, the good data length register, and the line status register are connected to a microprocessor through a bus, such that when the receive shift register receives a plurality of serial data, the good data length register counts the number of correct data, and the microprocessor uses the count of the good data length register as a number of times for reading the receiver buffer register thereby enhance the performance of reading data.

Abstract: An open terminal connector formed of a plug-in connector, a circuit board, a terminal block, baffles, an electrically insulative inner housing and an electrically insulative outer housing, in which the baffles stop the molten material from entering wiring holes of the terminal block during molding of the inner housing and the outer housing and reinforce the structural strength of the connector after molding of the inner housing and the outer housing, and the outer housing is directly injection-molded on all parts to prohibit the internal metal conducting terminals and the circuit board from direct contact with the outside air, allowing the connector to be used under a high humidity and/or critical temperature environment.

Abstract: An equipment monitoring system line swap fast recovery method by installing a link detection mechanism in an Ethernet switch of an equipment monitoring system in an Ethernet between equipments at respective terminals of the Ethernet and a monitor equipment for enabling the monitor equipment to monitor working status of the equipments, such that when one equipment changed from a first port of the Ethernet switch to a second port thereof, the link detection mechanism detects the change of the connection, clears all address entry for the first port, and learns all address entry for the second port, for enabling the equipment monitoring system to keep functioning during the change of the connection.

Abstract: A remote data scope by installing a remote monitor equipment and an Ethernet switch in an Ethernet to monitor working status of remote equipments (computers or power generators, etc.) at terminals of the Ethernet. The Ethernet switch includes a packets switching mechanism adapted to copy working status packets of the remote equipments, a processor, a packets conversion mechanism controlled by the processor to convert the format of working status packets from the remote equipments, and communication systems adapted to transmit working status packets from the remote equipments to the packets switching mechanism and formatted working status packets from the packets conversion mechanism to the remote monitor equipment, for enabling the remote monitor equipment to unpack received formatted working status packets so as to obtain working status of the remote equipments.

Abstract: A remote equipment monitoring system with active warning function is constructed to include multiple remote equipments to be monitored, an Ethernet connected to the remote equipments, a remote monitor equipment installed in the Ethernet and adapted to monitor working status of the remote equipments, and an Ethernet switch installed in the Ethernet and adapted to collect working status messages of the remote equipment and forward collected working status message to the remote monitor equipment. The Ethernet switch has an event detection mechanism adapted to detect working status of the remote equipments, a processor adapted to analyze working status messages collected by the event detection mechanism, and a warning message generator controlled by the processor to generate a warning E-mail message to the remote monitor equipment when one working message judged to be the message of an abnormal working status.
